"The only realistic way to analyze the cost of subsidies is to view it as cost per unit of energy, not a summation of history. "

Lol, what a joke. After the initial investment, Renewables by definition produce more power for much cheaper over the life the unit. Hence why Nuclear and Coal are being priced out of the bottom of the market. 

Are you suggesting the price of of Nuclear Fuel and Fossil Fuel is free? The perhaps once these plants are built the fuel magically appears? Please enlighten me.
