New Hampshire already lags behind most of its neighbors in expanding its use of renewable energy but that hasn't stopped several groups from using this legislative session to attack those nascent efforts. Led by the Americans for Prosperity, these groups support a bill that would pull New Hampshire out of the nine-state Regional Greenhouse Gas Initiative. The program has reduced carbon dioxide emissions from electrical generation in those eight states by 40 percent over the last decade. Another bill calls for repealing the state's Electric Renewable Energy Portfolio, which requires utilities to get a percentage of their power from renewable sources. Supporters of these bills argue they would help bring down energy prices, which are blamed for driving away business from the state. But opponents contend there is little connection between these programs and high energy prices. Instead, they see this as veiled effort to assist the fossil fuel industry that has struggled to compete against cleaner burning natural gas and renewable sources.
