Maine Hits Clean Energy Grand Slam

As a baseball fan, I’m looking forward to watching the best players in the world compete for bragging rights in the 90th Major League Baseball All-Star game tonight. As a Maine resident for the past 11 years, I’m even more thrilled to see Maine regain its all-star status as a clean energy leader. Read more >

50% by 2035 National Renewable Electricity Standard Would Boost Economy and Cut Carbon Emissions

Today, Senator Tom Udall (D-NM) and several others introduced The Renewable Electricity Standard Act of 2019, a bill that would more than double the supply of renewable energy from 18% of US electricity generation in 2018 to at least 50% by 2035. It’s a strong proposal that builds on the recent clean energy momentum in the states and establishes a long-term national policy for renewable energy. A new UCS analysis shows that a national renewable electricity standard (RES) of 50% by 2035 would boost the economy, benefit consumers, and put the nation on a pathway to decarbonize the power sector by 2050.

5 Reasons Why HB 6, Ohio’s Nuclear Plant Subsidy Proposal, Should Be Rejected

Last November, UCS released Nuclear Power Dilemma, which found that more than one-third of existing nuclear plants, representing 22 percent of total US nuclear capacity, are uneconomic or slated to close over the next decade. This included the Davis-Besse and Perry plants in Ohio that are owned by Akron-based FirstEnergy Solutions. Replacing these plants with natural gas would cause emissions to rise at a time when we need to achieve deep cuts in emissions to limit the worst impacts of climate change.

7 Things People Got Wrong with our Recent ‘Nuclear Power Dilemma’ Report

On November 8, UCS released The Nuclear Power Dilemma: Declining Profits, Plant Closures, and the Threat of Rising Carbon Emissions, which found that more than one-third of existing nuclear plants, representing 22 percent of total US nuclear capacity, is uneconomic or slated to close over the next decade. Unfortunately, some of the media coverage and statements by the nuclear industry and other groups have mischaracterized our report and our past work. Here are seven points to correct the record.

Carbon Pricing is Key to Economic Viability of Xcel’s Nuclear Power Plants in Minnesota

A new UCS report released today found that more than one-third of U.S. nuclear plants–representing 22 percent of total US nuclear capacity–are uneconomic or slated to retire over the next decade under current market conditions. The UCS study, The Nuclear Power Dilemma, shows that the economic viability of the nation’s nuclear plants is threatened by low natural gas prices, the declining cost of renewable energy, investments in energy efficiency, and the costs of upgrading aging plants to ensure safe operation.
