Reply #40: Funny. But I have to break it to you:

It isn't near feasible, at least for the level of energy we demand. Twelve percent of our current demand would be very highest I'd expect solar to provide. I don't wish to discourage anyone, however, because 12 percent is significant, but if anybody thinks we can rely totally on solar, wind and geothermal, for all our energy needs, they're dreaming and should sit down and do the math sometime.

Also, if you ever get solar, wind and geothermal to the point where they do provide a significant amount of power, expect environmental damage to become significant, too. We simply can't support the population we have on the planet now.

There's no such thing as a free lunch.
