U.S. Sen. Sherrod Brown (D-OH) recently introduced legislation to renew a clean energy tax cut that delivered nearly $125 million to seven Ohio manufacturers. The Security in Energy and Manufacturing (SEAM) Act would renew the Advanced Energy Manufacturing Tax Credit program, also known as 48C, which provides investment tax credits of 30 percent for facilities that manufacture energy equipment. The stimulus program was more than three times oversubscribed, according to a news release announcing the bill.
