Humans and Energy: Crash Course World History 207
About | Information | History | Online | Facts | Discovery
In which Stan Muller subs for John Green and teaches you about energy and humanity. Today we discuss the ideas put forth by Alfred Crosby in his book, Children of the Sun. Historically, almost all of the energy that humans use has been directly or indirectly generated by the sun, whether that be food energy from plants, wind energy, direct solar energy, or fossil fuels. Stan looks into these different sources, and talks about how humanity will continue to use energy in the future as populations grow and energy resources become more scarce.

-
stan is awesome though
-
NOOOOOO IM TO USED TO THE JOHN GREEN sorry dude

I've got a question, does nuclear waste give off any heat at all? If it emits a noticeable amount of heat I vote we stick it in RTGs as fuel.
-
Like with most substitutes...class gets out early. Ftw
-
Staaaaaan!

Tive que curtir com o pé, porque com as mãos estava batendo palmas. Excelente vídeo, Stan.
I had to like it with my foot, 'cause my hands were applauding. Such an excellent talk. Nice work, Stan! -

You are the most adorable big teddy bear.
-
Ya know what I like Stan
-
your voice is so clear, thank you!

nuclear energy is the most sustainable. waste products have been substantially reduced and can be stored safely for millions of years without risk. The only solution which would eliminate energy production carbon footprint 100% by this time next year if we simply used it.

Stan!!!

The province of Ontario gets close to 60% of its power from nuclear. It is safe and clean. Wind and solar are unreliable.
-
Mr .Green is better
-
What happened to John Green on that day?
-
There's a great way of disposing of radioactive waste (and regular non recyclable waste for that matter). Just dump it into holes near plate melting areas (subduction zones). Eventually our garbage will be melted and absorbed into the Earth by magma.
-
I think you gave nuclear a bit of the short shrift in that video. There are ways to use nuclear waste to power reactors, and there are newer reactor designs that are much safer than ones used in the past. The reasons why we don't reprocess 97% of our waste and use it to fuel reactors, or use the newer designs are political in nature (read up on the Integral Fast Reactor to see what I'm getting at).

water power Is still solar power. Its the sun that moves the water to higher elevations via rain that then flows down stream to be used for work.
