LOL. Change we can count on. Just keep repeating to yourself that it will get cheaper and tap them ruby slippers three times... and lo, your feet will hurt and your voice is hoarse and the costs still have not come down 300%. But, I do agree that alternate energy is a good idea...it just needs more work to become a great idea.
I'd bet a cup of coffee, in 60 years, this country will achieve about 30 percent of it's power, via solar energy.
That being said, if we had any real leadership in this country, we'd have a many dozens of nuclear power plants on line, with more under construction.
