The Environmental Protection Agency has proposed increasing ethanol and other biofuels that must be blended into the nation’s fuel supplies over the next three years. Thursday’s announcement was welcomed by renewable fuel and farm groups but condemned by environmentalists and oil industry groups. The proposal also includes incentives for the use of biogas from farms and landfills, and biomass such as wood, to generate electricity to charge electric vehicles. It’s the first time the EPA has set biofuel targets on its own instead deferring to Congress. The agency opened a public comment period and will hold a hearing in January.
