Energy Videos for Newcomers to the Field

I’ve been preparing to make a few videos for newcomers to the subject of clean energy that answer basic questions on renewable energy, fossil fuels, nuclear energy, and the energy-related challenges we face. I'll be recording a series of short talks, aided by graphics, that point out that all our energy sources go back to the Big Bang, and come forward through time to us as follows:

Solar power is nuclear, of course, as all that hydrogen that became our sun billions of years ago undergoes fusion and emits enormous amounts of energy. That which we accumulated over hundreds of millions of years as fossil fuels (ancient biomass) we extract and burn as oil, coal, and natural gas. That which we receive right now, or in the very recent past, we have the potential to harvest as renewables: photovoltaics, concentrated solar power, wind, new biomass, run-of-river hydro, ocean current, and wave.

Tidal and geothermal are two energy-related products of the Big Bang that don’t derive from the sun. Tides are caused largely by the moon, which was created by a huge collision shortly after the formation of the Earth. Geothermal energy actually has four different causes (the energy of impacts, friction from heavier elements migrating toward the core, radioactive decay and compression due to gravity) -- all of which stem, however indirectly, from the mass and energy released in the Big Bang.

Nuclear energy comes from splitting some large atoms that resulted as simpler element combined after the Big Bang. Here, I’ll point out that nuclear reactions are perfectly safe when they occur 93 million miles from us – on the sun, where they belong.  Though, as we're slowly learning, this is not necessarily the case down here where we live.

Coincidentally, Bill Paul, our renewable energy finance guru, has been working along a similar vein, and sent me this masterpiece, a site on environmentalism for kids. I hope you’ll check it out.
