Renewable Energy vs Fossil Fuels Presentation 

NOTE: Many people have wondered why I didn't cover nuclear "properly". It is because nuclear is not technically a renewable, which was the focus of the talk. I had a brief from the school to do something on renewable energy specifically because the kids were about to embark on a week long project of building a solar air heater. That is why I didn't go into detail on nuclear, as I couldn't call it a "renewable", and I couldn't exactly leave mention of it out.

nuclear is the greener energy!

I have to strongly disagree. Nuclear is really the way forward in combination with solar wind etc.

Nuclear fanboys are going wild... 😂

Hydrogen is not a energy source but a expensive energy storage method thats best at extracting money from goverments.

Hydrogen is listed in "Renewables" but hydrogen is not an energy source

All my plants are screaming for their vital CO2. And back to my shoephone to save the world!

I appreciate that you touched upon the fact that even renewable energy is not clean. I get that you are pro renewable energy, especially solar, but I think you should have done an in depth comparison of renewables to nuclear, not fossil fuels. I think everyone already knows that fossil fuels are the least environmentally friendly and that we should curb our reliance on them. Not going in depth on nuclear is a disservice to your audience. Or are you just not very familiar with nuclear energy? If you compared it to renewables, you would find that the environmental impact of nuclear is substantially less than renewable energy sources like solar or wind, and we should be pushing more nuclear to ease reliance on fossil fuels. We're doing that here in Canada. In my province, more than 50% of our energy comes from nuclear and they are building three new SMRs.

Nuclear id only clean ehen you don't count the waste

Would have loved to have someone like you hold presentations when I was in high school, so glad that you have been doing this, and hopefully you have been and will continue doing presentations for younger students!

That "10g could power your phone for a month" calculation seems off to me. 240kJ is only 66Wh or so, at less then 50% efficiency, you get maybe 30Wh and that's it?

if you're a full time youtuber, why am I waiting forever for every bodies favourite segment! maaaaaaaailbag!

An oldie, but fun to watch! Not getting too deep, but I like your SFR rants. Speaking of which, the South Korean bike road with solar panels above it... It's complete bonkers too. No way in, no way out for kilometers. Noise from four lanes on the left and another four on the right, all you see is tarmac and cars, and you breath in the fumes. It's a nightmare.

If you rename refueling torepair, nuclear reactors are more renewable than solar and wind, because the installation remains operational for much longer.

It's great that you did this talk for the kids, I hope it inspires them to become scientists or engineers.

Hello Dave, wonderful video as always. I got curious though about your comment about the lifespan of solar panels. From my own research, the only data i could find on this is the <1% efficiency reduction per year. This would only mean roughly 20% reduction after 25 years. Do you know of any other factor that limits their lifespan?

The pace of renewable build out has been incredible lately, electricity prices where I live in northern Europe used to go negative at some nights with strong wind before, now they regularly go negative in the middle of days because of the massive installation of solar panels. 50% of electricity mid day in Europe now regularly come from solar panels.

Phenomenal presentation Dave, thanks very much for sharing!

Great presentation! Hopefully the kids don't read the comments here...
