Debate Over Value of Renewables Brings in Heavy Hitters
by RP Siegel
A recent article in The Economist describes a blog post by Charles Frank of the Brookings Institute in which he questions the methods that have been used to compare renewable energy sources with more traditional sources like coal, gas and nuclear.

Joskow’s reasoning is that since these intermittent sources vary their output at different times of the day and the year, that should be reflected in their value, since the demand for, and the price of electricity also varies throughout the day, at least in the commercial market.
