Wind Integration and the Cost of Carbon

Renewables are greenest when displacing coal, not gas.

With the abandonment of a nationwide energy policy by the previous Congress, states continue leading carbon mitigation efforts. Indeed, existing state policies and renewable portfolio standards (RPS) are already having a significant impact on the U.S. generation portfolio. FERC now proposes to weigh state policy as a consideration in transmission filings. Should state policies guide federal action? Will they suffice to reduce carbon emissions?

In light of coming GHG legislation, price transparency is the key to achieving cleaner generation through the dispatch of lower-carbon sources.
