FWIW, there are actually fewer "subsidies" to fossil fuels that could actually be redirected than most people here think. When you read HN articles and comments on the "fossil fuel subsidies", in my experience the bulk of these is "fossil fuel has this and that externality, and users of fossil fuels don't have to pay for it, so we count it as a subsidy". Whether you agree that this actually counts as subsidy or not, it's not like you can redirect it.
