I just read about these today on a german website. In Germany even as a private individual you can sell electricity by feeding into the grid whatever surplus you have from your solar installation or your backyard windmill and the tariffs that you get are so good that this law in Germany has caused emission reductions they had set for 2010 have already been reached and now they go for 45 percent greenhouse reduction by 2030 which is pretty spectacular. Also this has turned out good for the economy because the mount of people working in the renewable energy industry in Germany doubled from 2004 to 2006 to now 250,000 people. It's always good when something good is also economically beneficial because then it might actually work.
Anyways, several other countries are looking into this now and I was excited to read here
http://www.eere.energy.gov/states/ne.../news_id=11316 that someone is proposing this as a law in the State of Michigan now. I'm somewhat doubtful it will pass in Michigan because this state has not been one of the forerunners in environment (can't even get a decent tax break when you insulate your house).
I do have some visions of a solar roof and a small windmill behind the garage though
Imagine the excitement at every storm hehehe
