Yes, it is a scam ... It's about the money, not the greenery.

Not really, what you need to wonder is are they trying to fail in the first place? They mention the cost of creating there own power grid, why do that at all, it's a wast of money and not needed. All power flow can be measured and directed with some simple modification. If it's being done elsewhere why must it be harder to do in the US? Could it be because big business wants it to fail?

Your right about the amount of power from fossil fuels, as of 2006 seventy percent is derived from coal (50%) and oil and natural gas (20%). I don't think nuclear qualifies as green simply on the toxicity and length of toxicity of the waste left. While some clean up has worked by and large it is still getting worse and not better out there. If I lived in almost any major city in north America there would be so many days a year I couldn't go outside because of poor air quality, most of that is directly related to motor vehicle emissions, coal use, and manufacturing using chemicals. Thats why I would like to see major changes in fuel consumption standards for cars and trucks and more power generated from natural resources.

If greedy hands can be kept out of it going green can be cost effective.
