"Iowa's Republican senator on Wednesday raised concerns that U.S. Energy Secretary Rick Perry has commissioned a 'hastily developed' study of the reliability of the electric grid that appears 'geared to undermine' the wind energy industry.

In a letter sent to Perry, Senator Chuck Grassley asked a series of questions about the 60-day study he commissioned. Grassley also said the results were pre-determined and would show that intermittent energy sources like wind make the grid unstable.

Last month, Perry ordered the grid study and said Obama-era policies offering incentives for the deployment of renewable energy had come at the expense of energy sources like coal and nuclear."
