Sen. Josh Penry will be a main sponsor to a bill he hopes will boost Western Slope jobs, The Grand Junction Daily Sentinel reports. The measure, to be detailed in a press conference led by Gov. Bill Ritter later today, is designed to help clear the air around the Denver metropolitan area and boost jobs elsewhere in the state. The bill, to be co-sponsored in the Colorado Senate by Penry and Sen. Bruce Whitehead, D-Hesperus, would call on Xcel Energy to convert its Front Range coal-fired power plants to burn natural gas.
