Here's my humble opinion.
Most of these "alternative energy" systems are simply scams. Boondoggles. etc.
ALL are manufactured and used ONLY because of government "rebates", "credits", and "incentives".
None would exist without the taxpayer supporting it.
(OK, perhaps some veerrry small percentage where someone lives 50 miles from the nearest line.)
If you took away the taxpayer's contribution all of these companies (manufacturers and installers) would dry up and float away.
Sadly, none of them can compete with the cost to the customer for "conventional fuels" such as coal, gas, or nuclear.
There is nothing cheaper than Wyoming coal for producing energy, 24/7, day or night, calm or windy. No storage required. The sun's energy is already stored in the fuel from millions of years ago. And using the technology available today with scrubbers and such, the pollution becomes less and less every year.
But as Obama said:
"Under MY plan, electricity rates will necessarily skyrocket."
He's talking about alternative energy here, and Tax and Trade of course.
Here's my bottom line: If someone designs a wind or solar system without government handouts, if someone then builds that system without government handouts, if someone installs and maintains that system without government handouts, and if someone can produce energy, 24/7 with that system at a competitive rate, then GREAT! Go for it! I'm on board!
Until then, it's a scam. Like ethanol.

BTW, the retail rate for residential electricity here in Crook County with Powder River Energy is $0.055/KW-Hr. They don't produce the energy, they just distribute it. Much of our energy comes out of Gillette from the Dry Creek and Wyodak plants. In fact, they're having the grand opening of the new Dry Creek coal fired power plant on August 11, just north of Gillette.
