@@LordTalax prove it
Yeah, air conditioners used to be cool, but then they became a hot topic.
There was a guy that moved from here in cold northern Sweden to sunny, hot California. When he built his house he built it like we do here with LOTS of insulation. People laughed at him but he saved a ton on air conditioning because once the house was cooled it stayed cool without having to run the AC constantly because the heat outside couldn't get in.
so simple solution: install air conditioners backwards so the outside cools off
*Modern problem requires modern solution*

I live in an arid semi-desert, but because my house is surrounded by huge trees (trees that don't need lots of irrigation) my house is always cool, so I don't use air conditioning

Trees are natural Air Conditioning devices, and they don't produce CO2. remove your lawns and flower beds and try surrounding your selves with more trees.
YES!

In other words, you have a garden, and not just a lawn. 🙂
Yes, except in fire-prone areas where we're told to keep a wide vegetation-free perimeter.
@@ragnkja ya, pretty much. but I just see how people are scared of having huge trees these days, they want a lawn a few small fruiting trees and small shrubs, nothing that will be taller than their house, they might even just pave the front yard, that's the worst.
@@regular-joe that's a bummer
I remember one hot day when my friend and I were on a walk. We saw a small area of overgrowth with plants and flowers that were a little higher than our heads. We decided to check it out and couldn't BELIEVE the temperature difference within it! Must have been about 10 degrees (Fahrenheit) cooler.
Wow so now blame it on the developing countries, not addressing the fact few countries who have citizens pouring tons of co2 everyday.
AC "burns fossil" the same way the electric car does, but changing the electrical generation mix to Nuclear (France, for example) or renewable, the problem can be somewhat offset.
Somewhat offset yeah, but not with it's own slough of issues. Not to mention the TRILLIONS of dollars that need to go into the infrastructure and technology required to switch completely over to renewable sources. The tech just isn't even close to being there yet
@@DreadJester448 Nuclear is extremely viable, just a few billion dollars could retrofit some existing coal and gas plants to nuclear plants, which could drastically reduce emissions. But people are spooked by Nuclear because communists fucked up, so now we gotta deal with green peace being fucking retarded as usual.
Nice to see someone who ain't panicing about nuclear power 😊.
Wanna talk more about it?
@@SCIFIguy64 And Americans (Three Mile Island, Idaho Falls, others). And Japanese (Tokaimura (twice), Fukushima, others). And Canadians, French, Swiss, a bunch of other nations...
Nuclear power is super clean, but if done safely (including providing a _permanent_ storage solution for burnt fuel before letting a plant go operational) it's also super-expensive. Much more so than renewable.
@@giantnanomachine Thorium reactors wouldn't be nearly as expensive, and much better overall.
Well, to pump the heat from inside the house to outside has exactly the same effect than prevent it to enter in the first place. That's not an issue. The issue is the additionnal heat due to the power consumption.
Edit: so many likes, thank's! That surprised me because i was sure people would disagree.
Depends on whether sunlight would be reflected or not. A house is essentially a black body box, all the sunlight that enters gets turned into heat, if instead that sunlight was reflected back to space, that heat would not be a contributor to global heating.
@@CorwynGC It's still impossible for the house to reflect all that heat anyways. You can reduce it, yes, but the best you can do is maybe 20 degree difference, and when it's 110, that's not enough.
@@SCIFIguy64 If you are unwilling to do what it takes to reduce the problem because it doesn't completely fix the problem, you are dooming humanity. Thanks.

Thank you , I live in 50C summer country and I witnessed the exact thing happening, air conditioners were expensive and the max temperature was 43 44 now every house has one in each room , stores , shopping centres ... the sad part is when I talk about this people laugh and don’t believe 😔
I have always hated air conditioners. My father can't sleep without an ac in summers. He apparently has asthma as well so he can't bear the humidity caused by water based floor fans. Shit's bad and I can only see us dying very soon.
Because u are stupid. Air conditioners make up for about 4% of global greenhouse gas emissions into the atmosphere. U people are retarded if u think reducing the 4% by "60%" to a measly 2.5% of total greenhouse gas emissions, IS SOMEHOW JUSTIFIABLE. THOUSANDS AND THOUSANDS WILL DIE DUE TO HEAT WITHOUT AIR CONDITIONING, U FUCKING MORONS!!!
Well , the people are stupid.....
Fortunately, Atlanta is already very tree covered, keeping much of the city beautiful and nice and cool!

Isn't using a reversible heat pump more efficient than just burning fuels? So we pump the heat out when we want it cooler inside, and we pump the heat in when we want it warmer inside. I've also started to want an all-in-one unit that uses the waste heat from the AC to help the water heater.
Oh that sounds neat, could have it work in tandem with any solar power stuff if you have it too.
Reversible heat pumps are more efficient AT THE SITE, whether it is more efficient, or more green, depends on how you make your electricity. Solar plus a heat pump is a cheap, green, and efficient system. But still not as good as using more insulation, night flushing the heat, and other such passive measures.
Shad Sterling
My uncle’s “old” house, which they got built in the 1990s, has (or at least had) large “heat catchers” that warmed water for both heating the house and regular hot water. To facilitate this it had a gigantic hot water tank - 4000 litres if I remember correctly.
@@ragnkja Still do-able, and 4000 liters is not always required.
CorwynGC
Yup, the gigantic hot water tank was more because they had the capacity to heat that much water than because they needed that much hot water. Even if it’s just the capacity of a regular hot water tank, that’s still energy you don’t need to get from other sources. After all, that thing was/is about 20 times the size of a regular household hot water tank.
I guess I’ll just make my house out of ice cubes to cool myself and save the earth
Your refrigerator/freezer uses the same principle as air conditioning
How'd you make ice without refrigerator
@@CarlvanGoens nani!?
Don't drown XD
But who cools the ice?
Well the irony is, this video must have been made in an air conditioned office only!!
Insulation helps with heating and cooling the house alike. I use my A/C almost exclusively only for heating... Way more effective than the electric heating I used (that was only 100%). I feel pretty good about using A/C.
If we use non-heat trapping refrigerants, or always recycle / destroy them, and also convert to 100% renewable engergy, doesn't that eliminate all the problems of air conditioners?
Of course, better buildings, more green spaces, etc., are also good ideas in their own right.
A lot of poor people in Asia buy AC units now. They are buying the cheapest product available, they just dump it somewhere when it breaks because returning it for recycling would cost money they don't have and the installation is usually, say, "not meeting professional standards". If they can, they "fix" them but that often leaves them leaking (just more slowly).
Well this will probably cost way less than the entire us military Budget 😂
The mechanism of AC itself requires that some amount of heat is still released. Its impossible to have a 100% efficiency AC (except for when room temperature is equal to outdoor temperature).
I learned that in thermodynamics class
Good fucking luck converting to 100% renewable energy within your lifetime
Patrick W. Gilmore using non-heat trapping refrigerants to move out heat? How lmao
Air conditioning has one major plus: It can heat the building way more efficiently than traditional heating. Most Air Conditioning systems can reverse the cooling process and heat up your home by cooling the outside. Wich needs only ~10% of the energy than heating up the inside with coal, oil or gas.
With that being said: green or regenerative city design, using renewable energy sources and changing to greener coolants are still very important points. Thanks for this awesome video 🙌
Yes that is true.
I always felt hot air from the outside of air conditioners, but I never truly realized how until this video
I like how you give us this looming warning of our grim future with a few solutions that could help us in a cheerful way
I love the meme addition. Clever writing & production!
I get that this video was supposed to make me alarmed that Air Conditioning is a vicius cycle, but I had already realized that.
In fact, the very cool thing here is that now I know there's many possible solutions and therefore hope
Thank you for this. I never thought about it.
I heard about a group of students in Oregon in a science club that developed polyhedral container units that could be put inside walls and regulate temperature. It has a substance that changes state around the comfortable range of temperature. when it freezes the formation of bonds releases so much heat it warms the building, and when it melts it absorbs so much energy it cools the building, then when it gets cool at night it refreezes, resetting to keep the building cool again. They got special permission to make prototypes and install them in one building.
Air conditioning and pv power pair really well. After all most of the ac demand is during the day when the sun is shining. It should almost be required, if you want ac you have to install solar to balance it.
Yep. If you have solar panels, running a/c does not contribute to greenhouse gas emissions. All you are doing is moving heat inside to outside or other way around. You at least aren’t generating heat. It’s effectively the same as opening a window but just faster.
MinuteEarth: Don’t use AC
Me: How bout I do anyway
this is everyone, cutting down trees for the funs and not caring about how ac warms the earth ,sad
I find these videos really helpful in learning about whatever it is your teaching... Australia (where I live) don't use nuclear power because everyone screams when they hear the word "nuke." Could you make a video explaining how nuclear energy works?
“This is fine”
I love that one
2:56
*this is fine*
While I agree the vicious cycle of air conditioning, the proposed solution are focused on cities that need too cool, but don't address cities taht also need warm. For example, I live in Buenos Aires, where summer can reach 40°C and winter can reach below 0°C. During winter, the proposed solutions that for cooler buildings won't help, and they may even be worst, since people will have to use more energy to heat their homes. And I believe, based on statistic energy consumption, people in this city use way more energy during winter than summer.
Making your house more efficient by adding insulation works in both winter and summer.
I love you MinuteEarth. Absolutely.
Great video!! Thank you all for putting this together. Most people don't understand air conditioning translates to overall heat
few years back, only our house had an AC in the neighborhood but today everyone has it . .

Sorry to tell you this, but not enough people are willing to give up their ac. So, yeah, i hope we can find ways to make them more efficient and echo friendly. Using a fan isn't going to cut it.

@@PGraveDigger1 The entire southern U.S. would be abandoned. The North sometimes really needs A/C too though.
@@mattwolf7698 I live at the same latitude as the northern part of the USA, and I have never needed AC. It is a luxury and unnecessary for a large part of the USA.

😎
I wonder what the relations between PBS and MinuteStuff are now
nowadays air conditioners use eco friendly gases, and if ACs cool our homes and let out heat in the summer (heating the earth additionally) isn't that effect counteracted in winter when we heat our homes with ACs, generating hot air inside our homes and letting that cold air out again ?
That little HP reference made this video 10 times better
Nice Wall-E easter egg. I like that a lot. ❤️😉
I think you overestimate the proportion of energy produced being used to power AC units
'Climate change' sells. If your science research is not related to climate change somehow, you can forget about getting grants. So everybody jumps on the climate change gravy train.
@@PaulaJBean
That's funny because many government tend to be somewhat hostile toward climate research
especially the US, so I doubt they'll give much money to that sector
@@Pac0Master NASA was given a 2B dollar budget to study Climate Change Exclusively, by being told to divert all research over from Space Exploration and in Total the US spends over 166 Billion Dollars since 2016.
@@pathfinder290 Gonna need source for that.
www.popularmechanics.com/space/a13895/president-obama-nasa-funding/
"NASA would get $1.9 billion for Earth science, something that could prove contentious in Congress given the number of anthropogenic climate change deniers on Capitol Hill."
www.climatedollars.org/full-study/us-govt-funding-of-climate-change/
After examining the reports, and removing double counting, calculations show that from Fiscal Year 1993 to FY 2014 total U.S. expenditures on climate change amount to more than $166 billion in 2012 dollars.
I don't think the first argument that ACs bringing heat out from a room and leaving it to surroundings results in an increase of temperature on a global level because energy in earth is still the same it has just gone out from ur room it has not been added to the earth it was already present before and is present now also just that it's now outside the room.
Correct me if I'm wrong.
Yes, the total energy of the atmosphere is the same wether there is AC or not. But that doesn't mean that you can't create hot spots.
I mean yeah, the AC doesn't contribute to climate change by moving heat from one place to another (if you exclude the energy required to make so) like the video seems to say. But it contributes to heat up the local space around the AC. And boy oh boy is there a loooot of ACs in cities... Add up the cost of energy to make them work and bam > you simlultaneously heat up the cities, and add up to the climate change.
@Fortescue May be my bad but I'm not truly understanding your thoghts. If an AC is using energy to move the air from room to 'outside' and if that's causing the planet to heat up, then so does every other device, including fans , TV's , laptops. All are taking energy. Why not blame them?
But if you're saying that using appliances more, results in greater demand of electricity at the same time, and the coal used for producing the electricity causes, CO2 to go in the atmosphere, and hence result in global warming, then I get your point.

Another cool tech is "space cooling" where we literally radiate heat into space. This works by emitting infra red frequencies for which the atmosphere (=air, water vapor, clouds and dust) is transparent. Infra red telescopes use the same trick to look deep into space. Google: "radiating heat into space" and "TED space cooling"
The math behind that seems a bit dodgy, considering how low energy IR is. Interesting concept, and innovation is always welcome, nonetheless.
This reminds me of the old Patrick meme “Why don’t we just take Bikini Bottom and push it somewhere else?”
Your you tube video is outdated about air conditioners:
1) Modern Aircons use newer coolants and very soon may even use Co2 coolants as well. These coolants have only 1-4x times warming capacity of CO2 and not thousands of times as you are saying and through proper disposal they will not contribute anything to global warming as these coolants are buried deep inside earth.
2) The total heat released by aircon does create heat islands in cities but its impact in raising temperature is minuscule compared total atmospheric heat.
3) The only way in which aircons contribute to global warming is by consuming more electricity which uses more energy burning more fossil fuels but with greater use of renewable energy , even these could become redundant.
Well said brother, I was thinking the same as AC only moves heat from one side to the other and also make a minuscule heat increase by the motor and compressor, the only problem would be reducing energy consumption...
Thanks for this video!
Woow just watching this makes me warm
Definitely interesting, I never knew that AC’s alone contribute to global warming by a good amount. Summers are just gonna get hotter!
Just judging from title... No.
Air Conditioning units are just heat pumps, they just move heat from one place to another (if you don't count small amount of motor heat from compressor and fans)
This is an old comment but... do watch the video, it's more complicated than that.
I love the little meme at the end
It's why I use passive cooling AND being smart about how much light and heat enter my house to begin with. Use vegetation like trees and bushes to insulate the house externally from the sun. Use grey or neutral toned color curtains to allow some light in while still filtering out most of the infrared light (heat). Use overhead fans on low to keep air flowing around the house.
Thanks to air conditioning, this video was made possible
1. That is true in general for any device that uses electricity from the net and is not limited to AC in any way.
2. The localized warming might be true (you unfortunately didn't tell us which of your references that number cam from for easy confirmation and further details) but it can't contribute global warming because there is no change to the total heat energy in the system (Except for the waste heat from running the AC with electricity of course but again, that's true for running any electronic device and is not specific to AC). Putting it the way it was presented in the video is misleading IMO.
3. That's not an issue with AC, that's a waste management issue and affects all devices with components that are dangerous for the environment and (again) is not specific to AC at all.
The improvement suggestions are great and should be implemented IMO but the reasons/issues shown in this video are poor and/or misleading.
Most people won't understand unfortunately, though it is refreshing to see a few comments mentioning the fact that the total heat in the system remains the same, and you actually are not adding more heat
@@mrfoodarama Burning fossil fuels to power everything including a/c units, adds energy to the system. That is the problem. Oil is part of carbon sequestration, a long term process that keeps a lot of energy out of the system.
@@mrfoodarama tl;dr We are changing the system by quickly adding in energy from millions of years ago.
2. Yes, the total heat energy of the system does increase. You can't neglect the electrical energy consumed just because every electrical device consumes electrical energy. All the energy that is consumed by the air conditioner is sent out as heat, in addition to the heat that is pumped out from the inside. Therefore, the total heat of the system increases by the amount of energy consumed by the air conditioner.
@@jasonmraz3311 Earth is not a closed system. Energy goes in, energy goes out. Not necessarily at the same rate. The problem with global warming isn't heat, it's atmospheric conditions preventing heat from leaving.
Energy production is GOOD because it increases wealth and happiness and that in turn makes people care about the environment and the future.
How can this not be on trending page!!
love the planting roofs idea so much!
and then on the other hand there are water cooling systems large building owners/architects refuse to use to minimize cost and use of freons in regular a.c. units. all they require are existing pumps to bring natural cooled water from basement reservoirs to the solar panel-shaded roof tank to flow down floor by floor to cool the building by evaporative techniques(like swamp coolers). and some of the energy can be recaptured via microturbines in downpipes. it doesn't have to be a vicious cycle. or at least some passive cooling can help minimize workload of active cooling... more indoor plants and water features also help. heck, in developing countries, one of the better ways to lower neighborhood microbiomes is to spray their sidewalks during the summer. it cools the immediate area outside storefronts by a few degrees for a few hours.
Sounds like we need to urgently address the issue of heating homes since it is far more damaging!
Heating homes is about survival, not comfort. It isn't really possible to tell people in Britain or Scandinavia to get rid of heating.
@@pkmntrainermann4476 You are very unaware of how much cooling is VITAL to survival my new friend... No worries. I will hook you right up mate. I suggest spending a few summers in white sands new mexico or Kuwait if you would like a proper lesson in dealing with arid climates. Thankfully I now live far away from deserts these days. I have to now move, stack, and split *6 tons* of wood each year, by hand mind you to heat my home as that is the primary heat source available to me. Doing things like correcting the insolation, windows, and adding soap stone to my wood stove went a very long way to making sure that I don't have to use even more wood during the 6 months of winter I have to deal with. I can guarantee that in my town alone, at least 50% of the population has not done what I have done. Worse, there are a ton of oil fired heaters around here. So yes, addressing heating will be FAR more helpful to dealing with this issue since we only really need the AC for 3 out of 12 months. Why do we *NEED* it? Because some of us have family that literally will die in high heat that would be merely uncomfortable to others.
@@derptothemaxclearly I get that, I have been to Mexico, Arizona and malta, all of which where very hot or arid. However heating is needed from October to February in the UK, and this year it was still 10 celsius in April.
@@derptothemaxclearly Cooling is needed for survival but the amount of cooling that is needed is very less and most people who use AC are using it much more than necessary. An AC set at 27 degrees Celsius can ensure comfortable health whereas when people use AC at 24 degrees Celsius for example, it is nothing but addiction. In most places using an evaporative cooler (in dry places) or a dehumidifier (in humid places) can work very well enough and is much more sustainable than using ACs.
@@yashagrawal88 lived in 4 different desert climates in two different countries on opposite sides of the planet. Gotta say I disagree with you about evaporative coolers. They tend to be so inefficient that they are on left on constantly in addition to using water directly.
Future me not using AC during the summer: Ah that’s hot that is hot
I knew it! Been thinking this for years! Didn't think about the refrigerants tho.
What's the Solution on this with minimizing compromizes??
Luckily, we once tried to have air conditioner and immediately stopped when we figured out that ACs consume a lot of electricity and increase the electricity bill by almost 100x. And never thought about having one again 😁
if minisplit ones, find the inverter ones
If we start a global energy project, perhaps organized by the UN, to supply Thorium fueled nuclear power to the world, including the developing world, we could essentially solve these problem for good. Waste is managable, the energy is completely clean and molten salt reactors are very reliable and safe. Ideally we could fund this project with a form of extra-national tax that is adjusted based on GDP per capita. This way the whole world gets clean, cheap energy that is fair to everyone and doesn't affect economic competition between countries.
Sadly nucler power is too stigmatized for this to be very likley to catch on.
@@tubegerm6732 Yeah. It's really frustrating to know that we have the solution to this problem in our grasp but because misguided fearmongering we refuse to use it, even as the world burns and millions starve.

When I visit my Dad's friend in Phoenix, Arizona. I was so surprised that why A/C in the US is central system, I meant it used so much energy to cool the whole house. Compared with my country, Thailand, which we only turn on the a/c in the room we only used, mostly bedroom.

I like how the refrigerant leaking out is color coded to the two most common types of refrigerant in residential systems. R22 and R410a. (color of refrigerant tank)
Air conditioners that help stop the environment warming:

Air conditioners making it hotter outside isn't ironic lol, that's just how thermodynamics works
They do worse than tht
Hey guys i loved ur videos...plz keep it up...u guys are doing gr8 job.....
I Went To School For HVAC So I Feel Compelled To Stick Up For My Technician Brethren/Sistren By Reminding You That We're Trying Our Best To Combat The Greenhouse Issue By Using Less Harmful Refrigerants In Our AC Units. Our Technology Is Always Evolving, From The Tools We Use (Some Are Now Digitalized) To The Refrigerants We Attain To Replace The Harmful Ones.
That is the cutest sad CO2!
buildings that are naturlly cooler?
what happens if we live in those buildings during the winter?
You'd have to burn more fossil fuel at winter to get warm.
@Fortescue how does that work?
Fan: Did you forget about me? Yeah, use me.
1:00, I was confused as to how rooms which have a very low area than a city can increase the outside temperature by a few degrees.
Then it dawned on me that this is possible in dense downtown areas with lots of skyscrapers, where the rooms make up most of the city space. That could have been clarified.
40C (105F) where I'm at right now, This is fine...

Solar panels also help cooling roofs, as they absorb a big part of infrared and visible radiation
yeah but consume alot of eletricity
I usually use a swamp cooler, but that really only works well when it's not very humid.
1:17 actually the refrigerants don't trap heat, they bond to upper atmospheric ozone, destroying the ozone layer which leads to increased global temperatures.
The ozone layer is concentrated at the Earth's poles, blocking the Sun's thermal radiation from making contact with the sensitive polar ice caps.
Without the ozone layer, the thermal ice caps will melt more quickly, allowing more heat to stay in the Earth's atmosphere, etc etc. This is taking too long. You get the point.

Hi. I was unable to locate in the references the paper that studied the effect of heat generated by AC condensers on temperatures in cities.
I'd be thankful if you could point me in the right direction.
Are there practical designs that store the heat from summer to use it for heating during winter?
You forgot an important thing ! Entropy ! In fact, an air conditionner ALWAYS produces more heat than cold. That is because of the seconde principle of thermodynamics.
They don't produce cold, they suck out the heat energy from your house and pump it outside by a complex mechanism...
