What is a sensible energy transition? What are the key challenges? What are the requirements? How to prioritize the appropriate low carbon energy technologies? How to ensure global energy security? How to minimize short- and long-term environmental impacts? How to ensure the fastest possible energy transition?
Energy expert, Dr Tushar Choudhary will address these questions in this episode.

Brilliant
Thanks. Glad you found it informative
I like your video. Good summary.
When talking about costs, I think that every renewable energy carrier like lithium-ion, green hydrogen, metal-air, synthetic and bio fuels are always going to be more energy intensive and thus expensive to use compared to equivalent amount of energy being stored in fossil fuels.
Reason is thermodynamics. Renewing or making a fuel sustainably takes energy and more so than just refining fossil fuels.
That's basic science (to use your vocabulary).
Fossil fuels aren't actually cheap. They are cheap because they non-renewable. In addition, their low price is an illusion because their negative enviromental is very costly for economy.
Cheap energy is an idea which died. Only nuclear fusion can get it back.
We have to accept and adapt to higher prices. There is no way around it because thermodynamics claims what it claims.
Fossil fuel price is not any measure of good or desirable. It's low price is fundamentally incompatible with sustainable society because this price is precisely low due fossil fuels being non-renewable.
You mention that solar panels are an expensive investment. I really disagree. Return point of investment is inside 10 years today (around 8). Since people use energy through the their whole life, 10 years is nothing much.
I know a family who lives off the grid for years without bills. They have solar panels with sodium-ion battery and a heat pump. Not only do they don't have any bills, they're making money by selling electricity to the grid.
I'm also pro-nuclear. Great source of energy. Fast neutron reactors can power society for a very long time.
Thank you for your comment. As I mention in the video, the fastest path to address climate change is via a sensible transition. The key is to consider all crucial challenges and address them.

Yes, there are many aspects. It's funny how people made many advancements in science, but we don't seem to be capable of doing much more than burning fossil fuels when talking about energy production.
We're primitive in this regard.
I'm not sure how much did oil lobby contribute to inadequate funding in energy transition. I'm guessing a lot.

Yes, there are so many aspects. My point is that basic science doesn't support the idea of cheap energy. Nothing is actually cheap; fossil fuels, renewables or nuclear fission.
Using fossil fuels a lot is much more costly than the latter two, though. Negative enviromental impact is costly for the economy.
Only nuclear fusion can get cheap energy idea back.
It's funny how many advancements we've done in science, but we don't seem to be capable of doing much more than burning fossil fuels.

My discussion about cheap is in terms of current energy cost. For example price of electricity. And, the whole reason we want to transition is because of the externalities (environmental cost). For doing this correctly we have to consider the major challenges.

Interesting. How do you see world energetics in 100 years?
My estimate is that if we succed in transition; renewables 50%, nuclear 30% and 20% fossil fuels.
Let's leave nuclear fusion out as it's not currently an option and there are a lot of unknowns.
