Detractors have called the U.S. Environmental Protection Agency’s proposed limits on power plant emissions onerous and unachievable, but the Union of Concerned Scientists is out with a report that does more than fend off those claims. The group says the Clean Power Plan could go much further than it does in cutting carbon, simply by properly accounting for the demonstrated…

Cutting the U.S. greenhouse gas emissions that stoke climate change could save billions in energy costs and boost revenue for the natural gas industry, according to a new report from the World Resources Institute, a research organization that advocates for environmental sustainability. The report, Seeing Is Believing, focuses on five areas that account for 55…

An area in the U.S. Southwest that’s about half the size of Connecticut has emitted the country’s largest concentration of methane, a potent greenhouse gas, according to a new analysis of satellite data. The study, which was released jointly by the American Geophysical Union and NASA, found that between 2003 and 2009, the area released…

What happens when a manager of Naval Facilities Energy Initiatives decides to go “net zero” on his home in Washington, D.C.? You get a true zero-energy home, done right on a budget. Andrew Knox wanted to “walk the walk” of energy efficiency, so he and his wife, Elizabeth, had some decisions to make.  To attain…

American cars are using less gas per mile and emitting less carbon dioxide than ever before, according to a government analysis released Wednesday. The average fuel economy of 2013 models is 27.6 miles per gallon for cars and 19.8 miles per gallon for trucks, “both of which are all-time highs,” said the report from the…

A year after adding the term “polar vortex” to their vocabulary – and feeling its biting financial impact – Americans can look forward to spending less money to keep their homes warm this winter, whether they heat with natural gas, fuel oil, propane, or electricity, government energy-watchers said on Tuesday. The key driver behind the…

Last week a solar power company based in Australia announced plans to build the world’s first heart-shaped solar field in New Caledonia, a French island in the South Pacific that currently gets most of its energy from coal, oil, and gas. The “heart shape” of Conergy’s forthcoming solar installation was inspired by the neighboring topography…

Like a lot of technologies that might be enlisted in the fight against climate change, carbon capture has faced a bit of a chicken-and-egg dilemma, castigated by skeptics as unproven yet given little opportunity to demonstrate its efficacy on a large scale. That begins to change today with the opening of the Boundary Dam Carbon…

As Indian Prime Minister Narendra Modi met with U.S. President Barack Obama Tuesday, clean energy was on the agenda. A joint editorial from the leaders promised they would discuss ways to “expand affordable renewable energy” in India during the prime minister’s visit, his first official trip to the States. The word “affordable” is key everywhere,…

Green Mountain Power just broke ground on a 2 megawatt photovoltaic (PV) plant in Rutland, Vermont. While some other large PV systems planned for the area have met with strong opposition (some residents worry large, ground-mount solar arrays will be an eyesore on the state’s pastoral landscape), this project seems to be welcomed with open arms. Why? It’s being built on a 9.5-acre closed landfill.
