Radio Iowa: Republicans in the Iowa Senate have ratified a plan that will limit energy efficiency programs run by Iowa utilities, reducing annual charges on gas and electric bills in Iowa by an estimated $100 million. Sen. Rob Hogg, a Democrat from Cedar Rapids, predicted many of the 20,000 Iowans who work in the energy efficiency industry will lose their jobs if the governor signs the bill into law. Sen. Michael Breitbach, a Republican from Strawberry Point, said an estimated $150 million worth of rebates and energy efficiency incentives will still be handed out annually by Iowa electric and gas utilities.
