Science: Discussing EVs, E-bikes, E-scooters, and some latest climate science
HTML-код
- Опубликовано: 1 фев 2024
- Quick little catchup of the last month, and some discussion on what's going on. I wanted to discuss EVs and E-bikes, and link to some studies that combat some of the disinformation I've been seeing lately on EVs.
I cut some of the climate science discussion to keep the video short. I may get into this in more detail in a future video if there is enough interest (Hansen et al, Climate Sensitivity, Aerosols, Ocean transportation fuel policy changes and how they impact 2024, etc)
Timestamps:
07:46 Are EVs worse than ICE? What about E-bikes and E-Scooters?

Totally agree with your summary - the future must be about smarter transportation networks and urban design around cycling and light transportation, I can't help but feel your view of 'greens' is very simplistic.. I don't know many greens who think that we switch to EVs and job done. Everybody knows that 2 cars per household is just madness, that EVs powered by coal-plants are worse than from renewable/low carbon sources. The 'green man' stereotype you describe simply does not exist - enthusiasm for EVs? of course, as a pedestrian it's a no-brainer. I live in Paris, and smelling ICE exhausts and hearing their chug is the biggest streetside discomfort in the city now. The 'greens' in France and Paris for instance seem to have focused on a cycling-friendly pivot, far from the stereotype you describe. They've just upped the parking fees for cars above a certain weight too (targetting city SUVs)... They seem a lot more enlightened than you give them credit for.
Totally agree. For clarity, that's not MY view but it's how the green movement is perceived by many on the right. My audience (in the homesteading space) tends to lean quite right, so I often attempt to curb some of the common misconceptions. My position on climate is that we should (and NEED) to do EVERYTHING that isn't mutually exclusive.
Electrify transportation, regenerative agriculture, biodiversity protections and restoration, recycle waste, eliminate plastic, which often requires alternative materials development like myco-materials, carbon storage and capture, planting trees, redesigning cities, and heck even human societal norms like buying local instead of global, supporting farmers markets, eating WAY less meat, not supporting anything unsustainable, etc.
It's at the point now where if we do everything we can it's likely still too late to prevent societal constriction in the next 50 years, but if we fail, we are looking at much worse outcomes, including potentially extinction through biodiversity collapse impacting food chains and eventually human agriculture.
Thanks for the comment, I totally agree with you.
City Nerd on RUclips is an excellent channel offering insights on city planning and transportation.
I'm living on the west coast, but the government hasn't indicated whether E-Bikes are allowed on roads or if they're considered vehicles or bicycles and either do or don't require insurance (vehicle).
We've got a relatively green grid, but this creates serious problems for anyone wanting a true E-bike and not end up in court. 🤦♀️
The Provincial Government hasn't really been pushing green technology either for home, like heat exchangers, replacing inefficient windows.
I use transit, walk, but I am not young anymore and would like to find a quick way to get around for longer distances, but right now, it's confusing.
Yo Bestie! It's been a while so I just thought I'd send you some happy vibes.
My ebike remains the best thing I've bought in the last 5 years. So many car miles saved - and I managed to do a camping holiday on it last year. Previously I'd just been riding around my local area, but it was cool to see another part of my country for next to nothing. Like you said, it's great for your health, and in the long term great for your pocket too.
All the best :)
Nice!
I think this is the year we will be growing actually! My mom and dad, aged in years say it would be hard to grow in a food forest because of our clay soil. I told them that you can slowly change clay to more soil-like, but it is a process lol. Otherwise, we have a garden bed and I am making a greenhouse (I live in Zone 7, but I want to grow Citrus.) I am thinking of using an earthen structure to slowly change/integrate my greenhouse over time.
Also, yeah these numbers and studies get me a tad depressed too. We need more action, and unfortunately both the media and government are kind of out of touch. Wish you the best!
Thanks for referencing the specific studies, it helps a lot when citing your videos among friends
It's my pleasure
Cannot tell you how excited I was when a new video popped up from you and the first word of the title was 'science' 😂
Fantastic discussion as always and thank you for sharing the references. Absolutely would love a follow up going into more detail
❤️
Great Video, here are some concerns
1) I live completely offgrid in Northern BC , my home solar system is just 2500 watts , fir me to run a 240v ev charging system I would need to expand my system upwards of 5-6 fold to get an additional 7500 watts it would take to charge an EV truck…unrealistic
2) we are just supporting a system that is evonomically colonizing smaller poorer African/south American countries. I would rather build out a mining industry here that we can demand cleaner safer facilities.
3) BC hydro grid is falling apart , last I heard they are 3-4 billion behind in maintenance, and now everyone is going to increase the system load by 7500 watts per vehicle. It can’tdo it without serious economic inputs .
4) we should be going to a regional green policy, if you have sun in your area use PV , if you have great wind use wind turbines , if you are in northern regions without either use fossil fuel or nuclear …. One shoe doesn’t fit all……
I work really hard to offset my ICE carbon footprint a holistic approach is needed
Cheers
FYI, CNG is Compressed Natural Gas not combined. It is a real technology in Toronto where it powers fleets and taxis. Better than petrol and diesel, but not electric.
thank you for this. i just watched the entire video, and i did not find any misstep, and i want to endorse what you said about the unnecessary commuting to work!!!
Wonderful!
I need a bit of translation with the terms used... particularly scooter. In Melbourne we have scooters that you stand up on a board close to the ground... but they are for short distances because of the lack of comfort. We have light electric motor bikes that are commonly used for food delivery. We have electric bikes that are a heavy version of a push bike. A normal geared bike usually can get you to most places if the weather permits. I appreciate these kinds of videos. I certainly agree that having cities that are walkable, safe for bike riding, with efficient, readily accessible, and frequent public transport is critical to reduce car transport needs. Internet availability allows many people to work at home.
Talking about working from home... I'm in Melbourne for a year (carbon footprint of a plane from Mexico to Australia and back again) so that my daughter in law can return to work. She works at home. Since it's a flat, my 'job' is to take my granddaughter out of the flat for daily adventures in the morning and the afternoon. We often use the free trams to get us to the libraries for song group, museum children's and different parks. And my other 'job' is to visit my mother when my granddaughter is asleep because my mother has short term memory loss after two major falls and we want her to maintain living at home. I take my mother for a daily walk in the park and other activities. Sometimes I feel that I have walked km back and forth from one place to the other...so people can be 'at home'. Melbourne does have many beautiful tree lined streets and gracious parks. I'll miss them when I return to dusty Chihuahua.
This is an important point, and one I found when searching for academic studies on "scooters". These can mean anything from the small wheel plank standing style scooters, to a moped, which is like a small motorcycle.
The second study mentioned here is the former.
Thank you for this. I sure appreciate how you deal with the myths out there about EV's. We are am looking to buy a PHEV sometime in the next few years when our current little ICE car is ready to be replaced.
We bought pedal-assisted E-bikes in the Fall. We don't need them for commuting because we are retired. However, we find them exhilerating to ride. Far more enjoyable than driving a car (when the weather is good).
If you are looking for pedal assisted e-bike manufacturers to talk to, may I suggest Erik at WestLake E bikes? It is locally owned (Prince Edward County).
Great video, Keith. Everything is spot on.
It always peeves me when I hear people insist that EVs are being charged from coal plants and therefore are worse than ICE cars. I imagine it's true in some places, but I heard that lie from multiple people back when I lived in WA (where something like 70% of the electricity comes from hydropower). So many people have been sold these lies.
After watching my son commute on his ebike for several years, I'm tempted to get an ebike for around-town errands. Unfortunately, it wouldn't do for my commute (13 mi + ~900' elevation), so I am commuting in a hybrid for now and hoping for a Nissan Leaf or something similar in the future.
Love it :)
I love my ebike. I've been riding it for over half the trips where I'd normally be taking my car, even through the winter. Got a long-tail cargo style to take my kids to appointments.
It has made it VERY obvious how poor some of our city planning is for biking/walking. I tried to go to pick up some embroidery floss earlier today (I'm patching up an old hoodie). There's a lovely bike path on that side of town, so I took that. But quickly realized that there was no curbcut/crosswalk from the bike path to the whole line of businesses on the other side. I ended up having to pick up my bike and dart across 4 lanes of traffic. Apparently bike riding is for fun, and if you want to go shopping, you should have a car. :(
Ive had my ebike (Aventon Aventure 1) for 6 months now, nice mid range bike, no complaints. Just dont sit flat on the seat when you go over bumps.
It is just 3 miles to get to work which ive done perfectly fine with my mountain bike, but its nice to have an ebike so i dont have to do work to go work at my job. All i have to do is charge it every couple days. Im usually pedaling with the highest pedal assist setting, so im not even getting the maximum milage.
Also, since im on a bike im able to have about 80% of my route to work be wooded trails.
As a plant addict, getting to look at plants while im on my way to plant plants to make money so i can buy more plants; is wonderful.
Wow what a great commute into work :)
Yes, city redesign! Smaller communities with walking access to gardens, shops, etc ❤
I'm excited to see your ebike deal video! I had an escooter years ago when they first came out. I went the scooter option because I liked having turn signals and being treated more like a car. It was fantastic to get to work on. The boss let me park it inside, so I didn't have to worry about it being stolen. I think that's the biggest worry for me, right now, that's keeping me from getting an ebike again. Bicycles get stolen all the time in this city. Where could I go and not worry about my ebike being stolen?
Right now, I just have an old 3 speed bicycle from the 1970s that I ride around in the community. But I don't use it for errands or anything where I'd have to leave it unattended because I worry it'll get stolen despite being practically an antique.
Thank you #SaveSoil #Consciousplanet 😊
Ive been wanting an ebike for a long time and i think you just gave me the perfect excuse!
Questions
If you moved to the desert and wanted to have a backyard garden how would you build it and what would you do for water retention?.
What growing beds would you choose?
I've watched Geoff Lawton so I do get the concept but I wanna grow vegetables more than trees. I definitely agree that shade is important because the sun is brutal in the desert. Not to mention water is basically non existent.
Would you give me the what when where how's ins and outs of what you would do in the desert to have a small veg garden? Please and thank you.
I've never done it before, so I would start copying what Geoff Lawton does in the greening the desert project.
One minor nitpick. All climate models do not feed into each other. They are parallel models that are then averaged together. What happened though was that some models started to deviate (known as Hot Models) from the majority. Those that deviated didn't seem to align with historical data so they were de-weighted in the averaging. Turns out those models are more likely the better fit as we understand more, and if so we are totally screwed.
Not true. Some models are independent but many do feed into eachother. The output of many are used to determine and refine the starting assumptions of others. For examples, there are some models which seek to calculate current Earth albedo, and future albedo changes, and then other models used those numbers (and updates) as the core values for albedo in their warming models.
Other models simulate GHG emissions through NG pipelines, and use methsat data to verify and refine. These values then feed into warming models.
The same thing for ice sheet melting and sea level rise. These values then feed back into albedo models, since higher surface level increases solar absorption due to albedo changes.
Every single model has core assumptions. Every variable used in the model is derived somewhere else, often in other models which are constantly updated.
I was just reading about how an aerosol model was being used to refine cloud nucleation in another model, as the aerosol model was updated with recent observations and new data, so the cloud nucleation model had to then be updated, which then caused an update to climate sensitivity models, which is essentially what caused the update of the Hansen et al paper.
@@CanadianPermacultureLegacy No, that is not what "feed into each other" mean in data science. When you do that, it means the data inputs for a model are directly fed by the outputs of another. What you describe is the idea of controls and variability cross checking for *tuning* of models. That is not feeding one model into another.
That is not to say these models are not fed by others. Often there can be smaller, more specific "feeder" models that provide specific inputs. Those are what you are describing with Albedo, but those are not the big climate models you are referring to in the video.
Thank you for doing this video. Lately, I've been reading about electric cars being twice as heavy as gas-powered cars. The point being that the heavier electric cars would use up the tires quicker. So you would have to buy tires sooner with an electric car than if you drove a gas-powered car. What?! Electric cars have very few parts, so there's no engine. Does this make sense?! Is this just scare tactics like you said from the oil companies?
Like all propaganda, it's based in truth, just not the whole truth. It's true that they go through tires faster IF you drive them the same. However, with regenerative braking, you are almost never actively using your brakes, which means your tires are almost always in rolling friction, not sliding friction. If you drive the EV properly, and not like a maniac, then you almost never need to replace brakes or tires.
I've gone 5 years on the same brakes, and the last time I got them checked (when I put in my winter tires) they said they are pretty much brand new. I've also had the same tires and winter tires for 5 years, but will likely need new ones next year or the one after. That's pretty standard tire wear compared to an ICE vehicle.
However, I also don't need any oil changes, no transmission work, etc. There are like 6 parts on an EV that wear. Sure there is the battery, but if and when I replace that, I have a brand new vehicle. So it's not so much about spending 20k to replace the battery, but being ABLE to get a "brand new EV" for $20k.
Either way, in 5 years the car has paid for itself off fuel savings plus about another 10-20%, so its almost like an investment. Plus I now have a ~$30k asset. IVE vehicles are financial liabilities, EVs are investments. I did a video on this, with numbers, last year if you are interested in more details.
@@CanadianPermacultureLegacy Sorry...thought you had only a 1 paragraph answer, but there are some points...tires on EVs don't last forever. Also, with Tesla dropping new car cost (per their mission), currently EV resale values are dropping more than in the previous years. Probably the reason Hertz is selling much of their Tesla cars. Not a reason not to get an EV, but needs to be said.
To be fair, reasonably driven regen braking electric cars almost never need brake replacement. But, reasonably driven electric cars have about a 30% increased tire wear vs equivalent classed ICE cars. But tire engineering hasn't advanced much on the ICE front while it is advancing on the electric front. ICE cars are so noisy that tire noise wasn't a thing. Companies like Firestone are engineering quieter tires for EVs that can take the greater weight. The hope is to get similar mileage as with ICE (hopefully better) per tire.
From a psychological perspective: EV tire wear is higher because people on average don't drive the same way as with ICE cars. The insane acceleration is so fun than people really gun it and then sometimes have to slow much more rapidly. Heavy acceleration/deceleration wears tires more. Not necessary if you're always sedate but...
To counter this, the ABS/Traction control available with an electric motor is much superior to the hydraulic systems on an ICE car. That is why some people feel safer in a rear wheel drive EV over an AWD ICE car. And of course AWD EV is the best. With that comes the ability to better modulate brake and acceleration power so the wheels don't slip (where the fastest tire wear occurs). So, with the same sedate or insane driving but ignoring weight, EV tires will last longer.
Here are some reasons the increased tire cost is outweighed by other EV factors:
From a financial and economic lifecycle impact, an EV not wearing out brake pads (manufacturing cost, relacement cost and toxic brake dust), no transmission fluid/engine oil/hydraulic fluid (manufacturing, replacement and disposal cost). (EV industry will transition away from hydraulic as steer-by-wire and brake-by-wire are adopted-Cybertruck is current example of both), belts/seals/plugs (manufacturing, replacement and disposal cost). And the car itself...we have EVs over 1M miles in Europe
insideevs.com/news/592845/tesla-model-s-passes-1-million-miles/
Not having to replace your car because the engine is worn out is a big local and global savings. As well, since the motors will really last almost forever, rusted out/crashed EVs can give their motors up as replacement parts with plenty of life.
Yes, the carbon burden of building an EV currently is greater than an ICE car, but that advantage goes away in 6 months (renewable charged) to 2 years (Poland has one of the dirtiest grids). What isn't much realized is that batteries themselves are a renewable resource. Once your battery degrades to perhaps 80% in 10-20 years, it can then last decades in a stationary storage (home or grid storage-companies using used Nissan Leaf batteries currently). And then it can be recycled with massively less impact than virgin mining. A report came out in the last week projecting that 2050-2060 would be the point where we no longer need to mine battery minerals on Earth. Everything will be taken care of by recycling end of life batteries.
And cost...in China, in town EVs are cheaper than ICE equivalents. Tesla is aiming to produce a $20-25k vehicle in the next 2 years. Some Tesla models are now cheaper than the American average price (not cheap necessarily because the average price is pushed up by big luxury cars).
You can use your car's battery for electricity security (power your house) and energy arbitrage (selling electricity during grid stress times). Some people have made significant money in grid stressed areas like Texas and California. So this is a cost offset vs buying batteries to sit in your house.
EVs generally have improved safety engineering over legacy ICE vehicles. And EVs have much more advanced collision avoidance systems. A lot of that is influenced by Tesla as they prioritize safety more than other manufacturers. So engineering safety design is probably most important, but in head on collisions, lighter cars suffer the most deceleration so EVs are in principle safer than a similar sized ICE car.
From a societal perspective, realistically only EVs can be driven by artificial intelligence. Tesla's FSD Ai driving with about 700M miles of data so far is 6-10x safer than a human depending on highway vs city. So, your safety and the safety of others must be weighed against increased tire cost.
The majority of trips in N. America are 30 miles (per AAA). Once driverless EVs are permitted, small (lighter->less tire wear) robotaxis will become commonplace for transport-on-demand. So the cost per mile of transport (including purchase cost) could go down to $0.25 from perhaps $0.50 today. Better and cheaper utilization of societal resources so there is more available to do other useful things. You might choose to run a business with a fleet of these.

as a cyclist i delight in lowering everyone else's carbon footprint as they slow down their vehicles behind me
😆 🤣 😂
Given what you know about the importance of density how did you decide to live in a detached home in a less dense town? Asking because I also struggle with wanting a garden / more quiet but knowing it’s not great for us all to be in detached homes and far apart.
We bought this home before I became interested/aware in these things. Where I live now isn't just my decision (I personally would enjoy living in a tiny home somewhere on land, but that's not for everyone). That being said, having access to land in which to plant a food forest is really nice. However, I could also be very happy in the right city, in a dense urban environment with the proper outdoor spaces and access to healthy activities, and live in an extremely sustainable way. That would also be quite fulfilling to me.
Thank you for putting out an analysis that challenges the mainstream analysis. An simplified story necessarily cuts out edge cases and in depth analysis, so in the interest of a fair view I'll have to present a divergent edge case on e-bikes...
I'm an experienced and at one point professional cyclist with the technical skill to easily retrofit a bike to an eBike or could buy a new e-bike. But contrary to Keith's view, in my specific case I have chosen not to use an eBike.
1. I am building a food forest/permaculture system and as the initial setup gets done it's starting to take very little effort and definitely no intense (cardio or weight training) effort. Science's understanding of healthy levels of exercise has changed greatly in the past 10 years. So, rather than sitting on an indoor bike for exercise, I ride a regular bike for local things (10 mile/16 km) radius. It's hard to get enough exercise without resorting to exercise for it's own sake, so useful exercise needs to be preserved where possible.
2. Anything further than 16 km can generally be delivered with a lower carbon footprint than with an ICE vehicle trip, and probably with an EV trip. Certainly EV delivery trucks would take the carbon footprint of my package very low. Regular bicycle would be better. eBike...hard to say given the myriad of factors.
3. E-bikes depending on class are limited to 20-28mph. The unfit regular cyclist is about 10mph, fit 15mph, Tour de France pelotons are 28+mph. We see more severe injuries on e-bikes probably due to speed and skill.
www.reuters.com/article/us-health-ebike-injuries/e-bikes-show-distinct-pattern-of-severe-injuries-idUSKBN1YT0MV/
Once you get fit enough to ride an average of 15mph, your bike handling and safety skills have likely improved commensurately. Certainly as a Tour de France pro at 28+ mph, your skills are the best in the world. But taking a new rider and allowing them to go 28mph without commensurate skills is a real issue.
4. Let's assume we have commensurate skills to handle 20 mph on a Class 1 eBike...
Cycling in the Netherland is awesome and highly encouraged at 20 mph. Cycling in a big Canadian city or non-Dutch European city isn't as good but is decent. Cycling in the rural midwest N. America is a risky thing.
Cities generally accept cyclists. Midwest N. America seems to see cyclists at best as annoyances or worst as targets. While riding legally, safely and with consideration for cars, there is often honking at best. At worst, cars have actively tried to run me off the road. Drunk teenagers yes, but also a potential fatality.
The ability to dodge cars or handle a fall if knocked over by a car is easier at 15 mph than at 20 or 28. I'm hoping this isn't true everywhere in the Midwest e.g. Iowa should be better as they host RAGBRAI.
But, in conservative areas, there is a heightened hostility to change and EVs can be a target. I'm guessing eBikes will also be targeted.
This isn't so prevalent that I won't cycle, but it's another factor that goes into the decision matrix.
5. Car drivers on average are poor
AI is already 6-10x safer than the average driver, and humans are actually getting less safe (texting while driving) over than last few years. Getting hit by an unattentive driver is something you can't really control while cycling, but it's just that much worse if you're going faster on an eBike.
Drivers are bad especially around cyclists, so a cyclist travelling up to 2x what drivers are used to is yet another compounding factor.
I will feel better cycling on-road when the proportion of AI vs human drivers is much higher.
6. I can currently fold my bike, put it in a shopping cart with one hand, shop and then ride off.
No current eBike can do this, certainly not one handed, so you must lock it outside. This is an area where the Midwest is better than cities. In large cities, people will try to steal bikes, especially the more expensive bikes compared to keeping the bike with you (batteries can be targets). Additionally, some perverse people will mess with your brakes or axles presumably because they think it's funny if you crash because your wheel came off. So, you either keep your bike with you or do a mechanical check every time you ride off after locking your bike.
I've never seen this in the Midwest, but have in large cities.
7. Mortality
It's hard subject, but in the contest between tonnes of metal and a human, the human loses. Cycling is pretty safe, but with low speed defensive driving, driving in a car is probably safer (don't have statistics on this). But it's a consideration especially if you have alternatives like working from home, having things delivered etc.
You are welcome, but just to be very clear, the misinformation on EVs is not mainstream whatsowever, it's only mainstream on Rupert Murdoch's media empire. So if that's what someone watches, then I suppose it's mainstream, but so are many other conspiracy theories and misinformation lol
Read the rest of your post, agree with it completely. The only thing I'd like to add regarding injuries, as this is another argument I've heard against how dangerous pickleball (of all things) is for elderly people who play it. The injury rate for elderly people playing pickleball is really high. However, it keeps them active, and fit, and happy. So while there may be more strains, sore feet by them playing pickleball, increasing health care costs, other studies have shown that it's believed that overall healthcare costs are greatly REDUCED, because now these same people who would be otherwise sitting on a couch are up playing sports, sweating and exercising.
I believe the same thing happens when discussing taking people out of cars and putting them on bikes. Even though it may be a slightly dangerous thing to ride a bike (much less so if you are intelligent about where you ride it), the benefits of moving people out of cars (which, sitting in the same position for extended periods is one of the worst things we can do with our bodies), that the overall picture is much more bike-favored that the "e-bikes cause injuries" article states.
Obviously I think riding regular bikes is superior to e-bikes. I would give away my e-bike before I gave away my bike. However, in the cycling club I belong to, there are many elderly people in their 80s and they can keep up with us younger folk by riding an e-bike, whereas they previously left the club. These e-bikes keep them active, in ways that a bike wouldn't. So I do believe there is a place for these.
Also, even if people just simply use it to replace a vehicle drive, and they use the e-assist the whole time, the carbon footprint savings is quite large, and I'm all for it. That being said, I think it's imperative that we allow for this transition in our city designs, and design in bike paths for e-bikes (even separate from regular biking lanes, since many people on e-bikes FLY). Cities like Amsterdam can be used to templates of what good design looks like.
@@CanadianPermacultureLegacy And as usual, I agree. I'm not arguing that the next benefit of biking is less, only that one should consider all factors (as long as complex analysis doesn't reduce your ability to act.).
But on another note, when faced with a dilemma, choose the third option. A 3rd option would be mountain biking on trails with extra nature nutrition and impetus to save forests (we save what we love). Another 3rd option: stationary biking/xc skiing amongst conifers on our own properties. (I suspect this is novel enough it needs a video). Another 3rd option: Go play pickleball instead of riding bikes on streets (Weird that you mention this sport...just got invited to play, but as a competitive racquet sport person, I wonder if it's something I won't be able to play based on my history).
@@CanadianPermacultureLegacy From what I've seen when looking at Tesla vs other car manufacturer's coverage in the mainstream, downplaying/misreporting on Tesla (the only N. American mass market EV) is not limited to a single media empire. The going theory in the Tesla fanboy world is that since Tesla buys no advertising and people like to see anyone with aspirations put in their place, ALL mainstream media misreport on Tesla (and so to on EVs generally). So far looking at a year's worth of experiencing reporting fairness, this seems to hold true from my sampling. e.g. an OTR Tesla software update is reported as the end of the world and reasons why Tesla vehicles are the most dangerous and unreliable cars out there. Real mechanical design issue recalls of legacy manufacturers and long term patterns of recalls aren't reported at all.
@SeekingBeautifulDesign Love your response, totally agree. As for pickleball, it will depend on the group you can find. I play very competitively, come from competitive baseball and squash, and the high level pickleball games are a completely different sport than rec play. I think if you can find a high level group, you'd love it.
Thanks for bringing up the complexity of both earth systems AND how to model them! Chaos theory/complex systems theory just means earth does so much stuff the way that earth does stuff and we can barely keep up and sometimes science just can’t keep up. Hence why I believe that we don’t actually need too much “science” to communicate effectively with people that 1) the dominant belief system/worldview of human-supremacy just doesn’t work with the ways that earth works. 2) the global industrial economy, born out of that worldview, also pretty much doesn’t work with the ways that earth works. Our inner world and the resulting outer world that industrial humans (for the last 6k to 12k or so years, very generally speaking) have created, is fundamentally incompatible with the ways that earth does all the earth things.
All it really requires, for a majority of people to share the same version of reality and be in agreement with the basics is, just seeing this truth and then accepting it as simple, common sense, truth.
Fantastically worded rant! And I'm here for it!
@Keith- i feel like you might like a guy named Rosh D’Arcy- his channel is ‘all about climate’ (I think) anyway you might vibe with what he’s doing and find it helpful for what you’re doing 🙌
Ps- sorry for commenting on a few comments here, and being a little bit evangelical 🤣 I rarely indulge in comment threads anymore these days (thankfully mostly bc there’s a lot of planting and planning for planting to do!) but now and then when I see the memeified/regurgitated talking points crowd show up on a climate video I guess I get ranty
@Corrie-fd9ww thanks, I will check him out
I wonder how practical it would be to have an e-bike with a solar charger? Would it be feasible? Would it be an overall benefit to carbon reduction? Basically, the owner would have a couple battery packs and just swamp them out when needed.
Another perspective of the e-Bike compared to an electric car would be a safety comparison, especially a safety comparison by age. Falling off a bike when you are 50 is not the same experience as when falling off when you are 10.
Safety is a big reason why I'm going to be showing a fat tire bike, because they are more stable. I'm going to make sure to mention these points in the video.
For the solar charger, absolutely it's possible. A typical battery for an ebike is around 500-750 Wh. So for example, I did a video on an Aferiy portable charging station, and it had a foldable 200W solar panel. That panel could easily charge the backup battery through the day in 3-5 hours while you use the other.
I know that this is not what is being asked but we charge our e-bikes from our hoursehold electrical system but that is powered by our solar panels. because a charge typically lasts about 80 kms, we don't need to charge during rides. That can be done overnight. @@CanadianPermacultureLegacy
Can you do a video on the overall impact of electric stoves vs natural gas stoves (which are being banned)?
Have you seen climate towns video on that? It's fantastic
@@CanadianPermacultureLegacyI will have to check that out. Thanks!
@@CanadianPermacultureLegacyI just listened to their video. As a scientist myself, I would want a simple model created integrating the cleanliness of the grid as a variable and comparing the overall CO2 emissions of natural gas vs electric stove. I would want to know at what point does the cleanliness of the grid have to be to make electric an overall better option.
People are saying the metals for the batteries are not available for everyone, meaning we have this zero emission deal and cant provide everyone a vehicle.
How about horses? I am wondering How it would compare to e-bikes
That completely depends on what the horses eat. Hay in a field at their home? They are actually sequestering carbon with their poop, and the flushes of regrowth they cause when they eat grasses and trample them.
However, if they eat hay transported in from somewhere else, that had diesel machines to chop it down, bail it and transport it?And their manure is piled up and never turned and makes methane? Not nearly as good for the environment. In fact, likely just as bad as industrial cows.
One thing that people need to start advocating is for universal, standardized e-bike parts. As it stands, every e-bike has a different charger/battery. There needs to be international, future proofed replacements for these electronic parts.
Part of Taiwan's ebike boom is that there's a company that manufactures an interchangeable battery pack and also maintains a bunch of battery swap&charging stations to quickly top up your scooter's battery levels. Being able to quickly swap takes out a lot of the failure points inherent to EVs and greatly extends the lifespan of the scooters.
Support programs like that are huge for adoption.
@@CanadianPermacultureLegacy it's not even a support program, just a private company that's really good at making batteries. Seriously, if you're ever in Taiwan those gogoro charging stations are easy even if you're hopeless with mandarin like I am. Leagues above the charging stations stateside even with the tons of government funds that get thrown at them.
@@deathpyre42 Yeah the US needs some of that. Just a little point of clarification though, this infrastructure should definitely be considered supported by the government, that’s why it’s possible. When the government was “throwing” money at that battery technology they are using now there were people saying it was a waste. Give those stateside chargers a chance, they might be quite necessary given time, and when someone wants to give a company the credit for that technology, don’t let them haha. But anyway, that standardization is really important yeah.
@@partimentieveryday I'm not doubting the necessity. From what I've seen the ratio of usable stations/cash so far has been 0 built for 7.5 billion according to politico. In principle, I like the idea that you can do it better for less money as a government program because there's no need for profit and the government can be more transparent than a private company. In practice, it seems that government backing just means shady contractors who also lobby and contribute to campaigns get to siphon off far more money than a private company would end up spending to build the same thing, and that private companies are more transparent and up front to their shareholders than the us/canadian governments are to the taxpayer.
Policies can make change too. Why charge for mass transit? Make it free and get rid of the cost of collecting fares. And transit police. No sales tax on electric vehicles or bikes. Surcharges on coal fired utilities, like Nova Scotia, jerks. Separate bike lanes
I'm all for intigrating the use of e vehicals where it's approprate, but forcing it on everyone won't solve the problem. Nothing should be all or nothing. 😊
Totally agree. Nobody should be (and I don't believe anybody is) forcing it on people.
Hearing someone that actually knows what they are talking about is incredibly refreshing.
In my mind average global temperature is a roulette game and people hate me for saying this, my other perception that makes people angry is keep in mind that heat is always temporary and its only hot on the sunny side of the Universe because the heat escapes everynight and Lake tahoe still makes 12 ft of snow two years in a row.
I strongly agree that reducing transportation, increasing mass public transit, and increasing infrastructure for bikes/ebikes are great solutions to lower our energy impact.
There are a few things that worry me about transportation moving all electric. The main one is the matter of distribution of power. If much of the power is being consolidated to a grid that is easily controlled by just a few powerful peoples then there is a potential for abusing the network. Actually, its not even potential, I'd say its certain and just a matter of time and degree. Power corrupts, Absolute power corrupts absolutely.
The second thing that worries me about this whole climate change business is that does it even matter that much? I mean obviously there are many programs/science out there to really push the belief that it matters and that its a very big deal. But how do we know, for sure? (I don't want to get too meta here, but yeah..) Science is limited in its scope and we all know scientific truth flows where funding goes.
Just based on observing changes in my own belief system over the years.. It seems that many of the general narratives/stories pushed by science/mainstream-- even history aren't the whole truth and nothing but the truth. In fact, It seems that the more I dig the more there appears to be a relationship between the amount of programming they put a lot of energy into telling, and the truth. Particularly when it comes to matters of control.
Now, I'm not saying climate change is not true. That's a big can of worms that boils down to assumptions. It's not an argument that I care to have. I think the only thing that is true is change, so yeah, I believe in climate change. It may even be true in the way science is saying. That's fine, that could be the case. The point I'm driving at is perhaps climate change is not the main game in town. Maybe, its what seems to be the main item on the agenda, isn't actually the main item on the agenda.
I understand the comment, even if I disagree with it. (agree with the first paragraph).
However the consensus is pretty clear at this point, and we are now seeing measurable results that don't align with the models... because they are happening much faster than the conservative models. That's why the rhetoric has shifted from "climate change isn't real", to "okay its real but it's not that bad" to "Olay it's really bad but it's not from fossil fuels" to "okay it's from fossil fuels but the climate always changes".
I do agree though that there are wolves in sheep's clothing who will take advantage of any situation, ajd they are doing so with climate change. For example, now the plan from the fossil industry is to invest in carbon capture and storage, so that they can keep drilling.
Climate change is definitely not the only game in town and is not the full story! It is partially true. The whole story, or rather, what’s really driving it, is ecological overshoot of earth’s systems. And overshoot, while it’s a concept presented by people and mostly scientists, is in itself not scientific at all. It’s absolutely a fact, and a simple one at that, that. Whole lotta humans doing stuff to earth in many different ways, in an effort and goal to extract stuff to make stuff and then that stuff we make becomes waste- will absolutely change earth systems and degrade them, almost exclusively (although folks seem to like the nuance around a topic like carbon dioxide being plant food and so therefore forests are actually better off than before industrial human activity- which, is also only partially true and that topic has all sorts of depth and context, too)
It’s good to be skeptical of stuff. Especially in the realm of beliefs, opinions, religion, politics. But when it comes to simply just earth- how’s it actually work and maintain relative stability and resilience when undergoing change- which yes, change is inevitable- but then, how are industrial humans changing how earth just naturally changes? And the answer to that has nothing to do with narratives, beliefs or opinions. Earth absolutely has changed and will continue to rapidly change- and not just the weather! The weather changing is just one symptom. All parts of earth are and will rapidly change, because of how indiatrial humans have changed it, and on earth, change isn’t the incremental, linear trajectory most of us hold as a default mode of change. Like, we usually just assume change means inches over a month, or some other steady increment. Earth doesn’t always work that way, when it comes to earth changes. Changes are and will also be nonlinear, super linear, and exponential. All those words mean is- changes don’t happen the way we expect them to.
You (or someone else reading this) might like Jem Bendell’s new book called Breaking Together- a freedom loving response to collapse. In it, he explores all the ways that addressing climate change could become authoritarian control, but also how people’s valid fears of warped partial truths and potential for oppressive responses, are just another way to deny the reality of earth and earths systems, or remain in delusion about all of that. He also has lots of free YT videos about it, in case someone is skeptical of yet another money making attempt
Definitely agree that climate change isn't the root cause, that it is a symptom. A symptom of the true root case, which is overshoot. You may really enjoy my collapse video, because I discuss that there.
@@CanadianPermacultureLegacy Hey Keith, I watched that video when it came out(awesome video, by the way-- I bet it took a lot of work)
I agree with many things in that video and it really struck a chord when I watched it, I can't remember the specifics now-- but overall I liked it.
Climate change being a symptom of a bigger problem is something I'm on board with, too.
What I'm trying to get at (without publically stating too much) is that I think there is a much bigger game being played when it comes to energy and humans. I believe there are energy technologies(and healing tech, for that matter) being surpressed. They are far cleaner and more efficient. It's simply not here because they challenge existing power structures. Lots of the people I'm following or studied these days are proponents of such tech and have been killed, silenced, or censored. (Not just recently, going back 100yr+)
I believe the climate change and shift to "green" is mostly a distraction. The "Green" is basically just slightly greener, and still under control of the powers of power. I believe the real game is securing and controlling energy systems. Its about making sure the other energy tech doesn't get out. The real game is making sure the mainstream doesn't develop this tech and use it, as this would take power away from the powers of power.
Now is climate change happening? Again, Yes. Does it matter? Sure, it does. What I think what's more important is how we choose to focus our own energy in response to such things. Treating the symptom v treating the root cause.
I'd say the root cause is our energy tech. The control/power structures of energy technology.
That said, bringing awareness and excitement to the young tinkerers and brilliant minds coming onto the planet about things like corona motors, magnetos, polarities within rocks/crystals, algae/gasification systems, systems using m3rcury/gold, zero-point.. and all the likes... I think providing a space for spurring that innovation is a much better way to focus energy, in the long run, to address humanities overshooting.
Regardless of that, I think living more harmoniously with nature is paramount in any humans living on earth energy tech situation, super dirty or super green.
Probably I'm agreeing with much of what you were getting at in the overshooting video.
I hope this message finds you well! Thanks for your amazing contribution towards moving humanity in the right direction :)
All the best,
Tyler

2023 Canadian wildfires
From Wikipedia, the free encyclopedia
2023 Canadian wildfires - season to date (map data)
Beginning in March 2023, and with increased intensity starting in June, Canada was affected by a record-setting series of wildfires. All 13 provinces and territories were affected, with large fires in Alberta, British Columbia, the Northwest Territories, Nova Scotia, Ontario, and Quebec. The 2023 wildfire season had the most area burned in Canada's recorded history, surpassing the 1989, 1995, and 2014 fire seasons,[4][2] as well as in recorded North American history, surpassing the 2020 Western US wildfire season.[5][6]
How about solving the things we can .. Traffic is the largest contributor to green house gases "apart from the Us military". So my idea is , no commercial trucks on the road during day light hours , they cause all the slow downs on motorways and in cities . Make them work at night so they, and regular motorists move about as efficiently as possible . I used to spend 2 hours a day minimum in traffic , imagine if that was reduced or even eliminated entirely , it would double everyone's fuel economy , save wear and tear on the vehicles , and greatly reduce road rages .
This is a simple fix requiring no mining , no pollution from the manufacturing of battery's , No EV's having electrical fires that require 30 times the water to extinguish. Just a simple change in the law and presto , we cleaned up our act ..
Hard to say. I'm pretty sure that would instantly collapse the economy. I would much rather do something with policy that promotes buying local, to reduce the economics of buying global.
The only solution to traffic is providing viable alternatives to driving.
@@partimentieveryday Ok , I'll work on changing peoples habits .. You grow some wings .. We'll see who makes an impact .
@@5thelementcannabisproduction How about we all work on changing our habits :) Then we’ll see who makes an impact .
@@partimentieveryday Ya thats what I said , you wanted to reinvent society and 6000 years of development ..
lol... let's not be divisive... and ends with "orange man bad." Let's see, if gov't gave everyone an e-bike... this would be good for summer in the city, but not workable in Canadian winter, not so much because the battery temp/mileage would suffer, but for the same reason regular bikes don't get much use in the winter, pedaling around in -20C (or ice covered paths, etc) is only attempted by a few hardy souls. Then there's the issue of battery build logistics, probably workable for Canada (one e-bike per household? how many households?), but not at a bigger scale. Even if the unwilling had to use e-bikes, how many would be unable. The one solution thing never works. I'm sure you've already seen the articles about the evils of agriculture... if only we could stop eating! Please take a step back and discern what is being presented. And note that, yes, all those models are very complex and yes, there are many of them... and they consistently get it wrong. Are they getting better? Maybe (I hope so!). In the meantime, pay attention to the actual weather, and do your gardening... at least that reduces the transportation portion of agriculture, and gets you nutrient density, taste, and variety you can't otherwise get.
If you are on this channel, and think someone saying they will be a dictator day 1 and shouting drill baby drill is "your guy", or think you have some kind of gotcha saying "divisive politics", then I don't even know what to say.
I have nothing against Republicans, (heck, I voted to the right most of my life), but absolutely someone who will remove environmental protections day 1 in office is absolutely not someone I would personally vote for, nor should any sane person. Especially not someone watching permaculture videos. I will let you sort out your own mental disconnect there.
@@CanadianPermacultureLegacy Just pointing out the disconnect between proclaiming inclusiveness on the one hand and mocking a group on the other, in the same video no less. Don't think you've done either this strongly in the past so it was quite the contrast. Thankfully I don't have to chose between Republicans or Democrats, but Canada's political landscape isn't all that much better. Whether blue, red, orange, green, or purple, it's doubtful any will provide remedy for today's ills. Interesting times when the outcome seems quite important for future policy, yet much can said for the "uniparty" of career politicians pursuing the same outcomes regardless of party. None of the parties adhere to their historical ideals, that's for sure! Just a sidebar, not poking... I'm pretty sure there are plenty of permaculture practitioners that would also fall under the ex-pres supporting group down south. Regardless, your channel, do and say as you will. Do enjoy your permaculture vids, particularly because of the food forest & pond which don't typically appear in small scale permaculture content. And of course, context... tough to connect with permaculture folks in Florida or the tropics!
@vesc1389 Indeed I feel very much what you stated here... there isn't a party in Canada that represent me. Nobody understands the collapse we face and the urgency we need action, but also doesn't want to expand the very systems of capitalism that are producing it. Super frustrating.
That being said, what is happening in the US is extremely critically time sensitive and important, and has global ramifications. And I have no problem calling out "sides", and I don't see it as "sides" when I'm simply pointing out that one candidate very vocally wants to destroy the environment at the altar of the economy, and also has a track record of doing exactly that (pulling out of Paris agreement, canceling environmental protections, etc). It's too important to remain "unbiased", because I'm VERY biased towards protecting the natural world.
I don't see the "other side" as a whole lot better here. Sure the inflation reduction act was the single biggest climate action any president in US history ever did, but its also nit close to enough, and I'm very against his military spending and focus on helping people kill others.
Unfortunately we find ourselves in a day and age where not being political IS being political, and is being complicit in the destruction of our planet.
Sorry, but I think your suggestions are useless, and quite unworkable. Who would ever turn to mass transit which takes three hours to get you to the same place you could get to by car in fifteen minutes? My time is worth money, too, but is never included in such calculations. I can't even buy a Tesla. They don't have a retail outlet in my city, and that's supposing I could ever afford one in the first place. I am physically unable to use e-bikes, and they don't make one for people my weight. And how the H am I to go grocery shopping on an e-scooter? The idea is silly. I understand Ford has come out with the EV version of the F-150 and it is so under-powered and useless that people are returning them and demanding their money back. Oops for the EV revolution.
I think you should definitely do some more research on city design. Public transportation will definitely help you and your condition as you get older. You won’t be able to drive forever, none of us will. If your city’s public transit takes 3 hours to get to where you can in a car in 15 min, you should be advocating for better public transportation! Of course, if you don’t in fact live in a city, that doesn’t mean Los Angeles or NYC should be prevented from building their own!
Keep in mind my suggestions aren't to BAN people like yourself from using what you need. It's to promote and expand the options for people that can use them. Very very different things.
Good comeback. Me like.
