The outlook for clean energy remains strong because smart investments like state Renewable Portfolio Standards (RPS) are combining with technological innovation to produce tremendous growth for the industry and tens of thousands of good-paying American jobs. These policies have successfully stood up to forceful attacks from entrenched fossil fuel interests in more than a dozen states in the past year. Washington should take note that the public supports and wants more energy from renewable sources.

At the state level, fossil fuel interests have worked through the American Legislative Exchange Council (ALEC) to weaken or eliminate RPS, because the clean energy industry poses a competitive threat to their market share. State renewable energy standards are projected to add enough new renewable power capacity by 2025 to power 47 million homes.

So, it’s no surprise that fossil fuel interests like American Electric Power, Peabody Coal, ExxonMobil and others are working to rollback renewable energy laws. These corporations that sell electricity produced from coal and natural gas are in direct competition with electricity generated from clean energy sources. This year, ALEC members and fossil fuel-funded front groups worked to rollback RPS laws in at least 13 states. But, a bipartisan coalition of business leaders, farmers and clean energy advocates stopped them in their tracks. Of all the bills proposed by ALEC members to weaken or eliminate RPS, 0 out of 13 passed, including in key target states like Kansas, Missouri and North Carolina.

Despite failing completely in 2013, ALEC’s energy task force met last week to propose new model bills that would effectively gut RPS laws by allowing large, existing hydro and landfill gas and other electricity sources from out-of-state to count towards the Renewable Portfolio Standards. The Market-Power Renewables Act and the Renewable Energy Credit Act would let utilities meet the clean energy standards by purchasing credits from out-of-state companies instead of generating or buying their own clean energy. In effect, the new model bills would eliminate incentives for in-state clean energy investment that are creating jobs and economic opportunities. Since their inception 10 years ago, RPS laws have leveraged over $100 billion in private sector investment in clean energy in 29 states.

ALEC and fossil fuel-front groups are lobbying our state representatives and spreading disinformation behind closed doors to attack pro-clean energy laws. With energy policy mostly stalled at the federal level, fossil fuel-funded attacks on the state level will continue and likely ramp up in the future, posing a major threat to the clean energy industry and the policies that support its growth.
