30 percent federal tax credit for geothermal right now.
but we're libertarian
Just because you disagree with a policy, it doesn't make it wrong or hypocritical to take advantage of that policy.
I'll give an example of Social Security. I'm against the collection of funds in this way but when I reach age 67, I'll take whatever payments are available. If they hadn't taken the money from me, then I would have invested it on my own and been able to get the benefit from that, but because they did take the money, all I'm doing is trying to recoup the losses.
Similarily, here, the government should be taxing 0%, but they aren't so any tax credit is just trying to get back to normal. My preference would be that they do not subsidize any energy including the coal plants, and that they strictly enforce property rights by which companies would be liable for any pollution that goes outside their property. But instead, we have a system that showers subsidies to polluting energy and them indemnifies them against their pollution, and trickles some to clean energy in a pathetic attempt to appear balanced.
