Here is what some folks may miss in all this. Transitions take time. Trying to shut out coal and gasoline is going to require decades to prevent a major economic burden on the citizens and government.
For example, The Chevy Volt cost more than several of the Cadillac models. I went to the dealer and read the window stickers myself. It may be the way to go at some point but most people can't afford the damn thing.So gas needs to be affordable in the mean time until cars of that type can be made affordable to the mass's. IF the greenies and government want folks in hybrids and electric cars, the prices should be equal or LESS than gas burners.

Coal, Ok,so the scientist think we need to reduce the amount we use. Reduce regulations so new plants of Hydro, nuclear,whatever, can be built to replace it as a energy source. It is my understanding no new nuclear plants have been built in many years. I **** them. but anyway, Regulations are to strict. Cutting off the coal,and expecting the existing system to keep up is ludicrous. It can't keep up. The basic electric grid in this country is old,outdated and overloaded. Research it,I own stock in 2 energy company's so I am not stupid on that point.

But look at the big picture this way for a moment, let's imagine you are a scientist and the government hires you to study climate change. They hire 9 more folks. They explain the goals of the study and turn you loose.
7 of you decide we have a serious problem and changes need to be made. 3 feel the whole thing is bullshit and call it for what it is. Now those 3 have not done the job the government hired them to do. Poof, fired. The study is concluded and the ideas of the 7 are presented as they support the goals originally set. The 3 that are fired try to explain all this is bullshit. They are not invited on CNN or CBS to talk. Fox might let them on. Or a republican may let them speak at a event. But simply because they disagree, they are denied credibility by slanderous government and private industry.
If you were trying to sell solar panels, would you support someone who proved that coal was not as bad as claimed? NO it would work against your cause and industry. So you would pay someone,a lobbyist or reporter to "fix" the problem.

I don't think you will find many folks in the world that just enjoy dumping burnt motor oil on baby ducks or burning barrels of oil just to see the black clouds.
It is just sometimes the folks that support a clean environment don't think about the burden all the changes they demand puts on others.

As crazy as it sounds, discussions like this need to take place all over America.
Reduce regulations, I would also go as far as saying cut off patent control sooner so that better technology can be made affordable sooner.
