Solar Energy
As this wonderful little video from Alex, Ashley and Michael reminds us, we are smart to know and work with the Laws of Thermodynamics. For example-the “further” our energy source is from the “original” source, the sun, the more transfers that must occur before we use it, so the more useful energy lost (entropy)…
So, solar energy is a wonderful choice–only one transfer needed! If you (or your parents) are interested in learning more about solar power, Jeff Martin sent me this link:
It has great info photovoltaics, solar thermal, “zero-energy” buildings, wind power and much, much more…a great resource for anyone thinking of retrofitting solar or building solar. I think it even features a picture of Jeff’s house in the “zero-energy” section.
