Thanks Sheryl, that’s who I meant.

Almost no proponent of renewables will be honest with you about the cost per kWHr, the only true "apples to apples" method of comparing them to each other and to local energy.

In Colorado, energy costs about 4 cents per kWHr. The best renewable is solar thermal, which when you calculate the equipment cost after incentives over its lifetime, comes out to about 2 cents per kWHr. For most Coloradoans, that is not enough of a slam-dunk to justify it. Energy is usually more expensive in non-oil and gas states, and can be up to 20 cents per kWHr, making some renewables reasonably attractive.

But many in Colorado WILL buy a photovoltaic system that runs about 11 cents per kWHr after incentives. Pretty much a bad deal, but most of them are environmentalists who will lie and tell you their meter runs backwards all the time, to justify the embarrassment of the true cost they eventually realize.

Wind and geothermal both cost around 40 cents per kWHr after incentives over their short lifetimes - ergo their higher cost. Not smart economics nor ecovironomics.

Best bang for your buck? Seal all the cracks in your window frames, wall plates, and attic penetrations, and add insulation.

FYI, industrial renewables are a whole different animal, because economies of scale become two or three times as significant in reducing the cost per kWHr of industrial applications.

I was a North American Board of Certified Energy Practitioners, certified Solar Thermal Installer 2010-2013. To be certified I had to pass a test more difficult than the EIT exam I passed when I received my mechanical engineering degree. The NABCEP test contained most of the information above. My disclaimer: I am no longer in the solar thermal installation business.

i looked into many of the countries of the EU and they all use oil, coal or electricity. they have had very little luck with wind or sun power. the small amount they have done is kind of to satisfy some nutbars out there who want to believe that we have gone green. fossil fuels will be with us a long time.

Pamela - I hope you don't mind my posting this vid here. I've been paying attention to Jo Nova for several years now. I think more people need to know about her work.
