How to really support renewable energy

I was going to write a political post here. I decided against it: the election is generating enough sound and fury on all sides without my help.

Instead, I'll link to an especially sensible proposal on funding for the political football known as the Renewable Electricity Production Tax Credit. What about a tax on non-renewable electricity? An extra penny per kilowatt hour would add only a dollar or so to the average bill, but would more than cover the cost of extending the tax credit indefinitely.

Unfortunately, the idea that more expensive energy might actually be a good thing is likely to be too toxic for either party to touch, especially in an election year. Sigh...
