So, to be clear, if Obama got on TV and announced that no taxes would need to be paid on corporate or personal income from renewable energy sales, you would NOT consider that a form of subsidy? And he would get no resistance from the right, because it would just be "taking less of someone's money"?
No, that would be a subsidy, if it wasn't applied to all businesses equally. My point was that some people claim a tax cut, usually in the form of a rate cut, is "the same thing as spending." E.g., if a tax cut is expected to reduce revenues by $100 million, they will say it's the same as the government spending $100 million. It's not, for various reasons too off-topic to go into.
