Earlier quoted context omitted.
Not taxing a negative externality is a 'subsidy'? This a huge stretch. If this is true, the government must be subsidizing obese men to wear banana hammocks.
Say the government decided to let Wal-Mart park delivery trucks on your property for free ( i.e. decline to enforce your property right in favor of a business). Economically, it'd be indistinguishable from a subsidy. Shareholders don't care whether the government policy increases Wal-Mart's revenue or decreases its expenses. The same is true for power generation.
Even the renewables would then need more subsidies, to pay for increased manufacturing costs and the fuel for the trucks that repair their transmission lines.
Point is its obviously misleading to say that fossil fuels are more heavily subsidied than renewables. People who hear that will assume that fossil fuel companies are being given taxpaper money, as the renewable companies are, when that is not the case. I don't think lumping together "companies that receive free money" and "companies we think should be fined" is an honest way to frame the situation.
