A federal program that has cleaned up or removed 50,000 high-polluting diesel engines from U.S. roads is scheduled to be cut by 70 percent under President Barack Obama’s latest budget.
The program eliminated 230,000 tons of soot and smog-causing pollutants, slashed more than two
The U.S. Energy Department is investing up to $4.3 million in a pilot biomass project that will convert the stalks and leaves of corn plants into diesel fuel using a new chemical process.
The pilot plant in Indiana will be run by Mercurius Biofuels, whose goal is to convert the corn biomass
Sea surface temperatures along the northeastern U.S. were warmer in 2012 than during any year in the last 150 years, a new report finds. According to the National Oceanic and Atmospheric Administration’s (NOAA) latest Ecosystem Advisory for the Northeast Shelf, sea surface temperatures across the region — which extends from Cape Hatteras, N.C., to the Gulf of
In recent test flights, NASA researchers have confirmed that commercial airliners can safely fly on an alternative jet fuel blend and that under some conditions the biofuel mix produced 30 percent fewer emissions than typical jet fuel.

As atmospheric concentrations of carbon dioxide approach the milestone of 400 parts per million (ppm), a scientist at the Scripps Institution of Oceanography has launched a Website that will publish daily readings of CO2 concentrations, an online resource he hopes will drive home the urgent threat of rising greenhouse gas emissions.
Annual investment in renewable energy is predicted to triple between now and 2030, according to a report by Bloomberg New Energy Finance.
In an analysis of several factors shaping the global energy future — including economic conditions, market demands, and the evolution of technologies
Researchers at the Massachusetts Institute of Technology (MIT) say they have achieved a major breakthrough in the conversion of sunlight into electricity, surpassing what was long believed to be an absolute limit to the efficiency of solar cell devices.
Portugal generated more than 70 percent of its electricity from renewable sources of energy during the first quarter of 2013, a record amount fueled largely by hydroelectric and wind energy sources, according to a report from the country’s grid operator.
Hydroelectric generation provided 37 percent of the
The Danish capital is moving rapidly toward a zero-carbon future, as it erects wind farms, transforms its citywide heating systems, promotes energy efficiency, and lures more people out of their cars and onto public transportation and bikes.
Among the first sights to greet visitors to Denmark on
The so-called “artificial leaf,” a solar cell being developed by MIT and Harvard scientists to produce low-cost electricity, is now capable of “self healing” the damage that occurs during energy production, clearing a hurdle to deploying the device in the developing world, scientists say.
A wind farm being planned in a remote Alaska village will seek to demonstrate that small, vertical-axis turbines can produce more energy than conventional wind turbines and cause less environmental damage.
While the turbines used in most standard wind farm projects can produce turbulence that actually
U.S.-based BrightSource Energy has shelved its second major solar thermal project this year as the company and Pacific Gas and Electric terminated the utility’s contract to buy power generated by the plant in south-central California.
In an email, a BrightSource spokesman said the $2.9
Air pollution contributed to the premature deaths of more than 1.2 million people in China in 2010, or about 40 percent of early deaths worldwide caused by dirty air, according to a newly released analysis.
The findings, based on data from a study on the distribution and causes of death globally, categorized
A city in southern California this week passed a zoning regulation that requires developers to install solar power systems on every new house they build. Beginning next year, all new homes built on lots at least 7,000 square feet in size in Lancaster, Calif. will be required to produce at least one kilowatt of solar electricity.
