Cheaper?
Two things you may have missed. First, solar is on track to be the cheapest source of electricity. In Hawaii, it already is (even unsubsidized). In the southwest US, solar will be the cheapest electricity, at the retail level, by 2016 even without subsidies.
Second, if the full environmental cost of fossil fuel (the open pit mining, franking, ground water contamination, air pollution, global warming) was included in your electric bill rather than just dumped on your fellow citizens, you would be screaming for renewable power because its true cost is so much less.
