Grassley wrote in a letter to Energy Secretary Rick Perry: “I’m concerned that a hastily developed study, which appears to pre-determine that variable, renewable sources such as wind have undermined grid reliability, will not be viewed as credible, relevant or worthy of valuable taxpayer resources . . . Not only is Iowa's wind energy resource reliable, it's also affordable." (American Wind Energy Association graphic: Wind energy in the U.S., state production totals by megawatt)
Volcovici writes, "Perry served as governor of Texas, a leading oil-producing state, from 2000 when he succeeded President George W. Bush until 2015. Under his tenure, Texas became the country's leading wind energy producer. But Perry has also been a strong advocate of the fossil-fuel industry. He told Department of Energy staff that he wanted them to examine whether environmental regulations and tax credit programs that bolster wind and solar energy are forcing coal and nuclear plants to shut down prematurely."
