A Department of Energy study suggests America’s rivers are a vast untapped hydropower resource, and developing many of them could help combat climate change by using renewable energy, to reduce reliance on coal-fired power plants that emit climate-changing greenhouse gases. In all, undeveloped rivers and streams in the U.S. have. . .
U.S. greenhouse gas emissions fell nearly 10 percent from 2005 to 2012, more than halfway toward the United States’ 2020 target pledged at United Nations climate talks, according to the latest national emissions inventory. The report showed that emissions dropped 3.4 percent from 2012 to 2011, mostly due to a. . .
Researchers at the U.S. Naval Research Laboratory have now proven that it’s possible to power engines instead with a cheap, convenient supply of fuel: seawater. Scientists have spent nearly a decade laboring to turn the ocean into fuel. The breakthrough, demonstrated in a proof-of-concept test, was made possible by a specialized. . .
Wind energy is expected to make up about 4.6 percent of total U.S. electric power generation by 2015, totaling about 77,000 megawatts of wind power capacity nationwide, U.S. Energy Information Administration data show. That’s up from 3 percent in 2012, when total U.S. wind power generation capacity was about 60,000 megawatts. One. . .
Illinois is buying more renewable energy than any other state in the nation, which has reduced pollution by the equivalent of removing a million cars from the road over the past few years, according to a report released Friday by national and state environmental groups. A 2009 state law allowed. . .
The convenience of toilet paper is a comfort many Americans can’t picture themselves living without. America is the world largest market for toilet paper. Americans per capita use 23.6 rolls per year, totaling about 7 billion rolls a year for the country. Unfortunately, using toilet paper is not the most sustainable. . .
A New Jersey agency tasked with protecting the ecologically fragile Pinelands region narrowly defeated a proposal Friday to run a 22-mile natural gas pipeline through it. The decision delighted environmentalists, who had turned out by the hundreds to oppose the plan over the past six months. But it disheartened business. . .
When it comes to carbon emissions, don’t blame big cities, blame the suburbs, says a new study from the University of California, Berkeley. The study, released this past Monday, found that population-dense cities contribute less greenhouse-gas emissions per person than other areas of the United States. However, these cities’ suburbs are so. . .
Hawaii has become the first state in the union to ban plastic bags. All three of the counties in Hawaii have passed legislation banning plastic bags at checkout counters. On the Big Island, where consumers have been paying for plastic bags at checkout lines for the past year, the ban officially. . .
According to Scientific American, strains of a particular soil fungus, Fusarium oxysporum f. sp. cubense, or Foc, have struck a key variety of banana grown for export in Mozambique and Jordan. Scientists fear that if the banana fungus spreads further, the popular Cavendish banana could become critically threatened. The fungus, which has. . .
U.S. President Barack Obama on Saturday boasted of the nation’s progress in cutting dependence on foreign energy sources and lowering pollution levels, saying that the United States is now poised to control its own energy future. In his weekly radio address, Obama noted that for the first time in nearly. . .
Scientists at Chicago’s Lincoln Park Zoo are raising meadow jumping mice and releasing them into the wild to help restore dwindling Midwestern prairies. Right now, biologists there say only 1 percent of historical prairie grasslands remain in Illinois. So the zoo is raising the mice and other species to help. . .
A new paper published this week in the journal Environmental Science & Technology Letters written by a team of researchers in the Netherlands, describe how CO2 could be mixed with a fluid electrolyte, generating electrical energy in the process. A press release from the American Chemical Society, which publishes the journal, calls. . .
The world’s energy-related carbon dioxide emissions rose 1.4 percent in 2012 to a record high of 31.6 billion tons, even though the U.S. posted its lowest emissions since the mid-1990s, the International Energy Agency said Monday. In its annual World Energy Outlook report, the Paris-based IEA said top carbon polluter. . .
