Renewables Poised for Rapid Growth Worldwide

Renewables Poised for Rapid Growth Worldwide

About 500,000 solar panels are installed each day worldwide. In China, two wind turbines are built every hour. Those statistics are laid out in a new International Energy Agency report cataloguing the rise of renewable energy, which is expected to be the source of about 28 percent of the world’s electricity by 2021 — up from 23 percent last year. … Read More

U.S. Energy Shakeup Continues as Solar Capacity Triples

U.S. Energy Shakeup Continues as Solar Capacity Triples

Solar power capacity in the U.S. will have nearly tripled in size in less than three years by 2017 amid an energy shakeup that has seen natural gas solidify its position as the country’s chief source of electricity and coal power continue to fade, according to monthly data published by the U.S. Department of Energy. Cutting carbon dioxide … Read More

Scientists Warn Negative Emissions Are a ‘Moral Hazard’

Scientists Warn Negative Emissions Are a ‘Moral Hazard’

Removing carbon dioxide emissions from the atmosphere to prevent global warming from becoming catastrophic may be a fool’s game amounting to a “moral hazard par excellence,” according to a paper published Thursday in the journal Science. Nobody knows if atmospheric carbon removal — known as negative emissions — will work, and it could delay … Read More

Ethanol in U.S. Gas Tanks is Backfiring for Climate Change

Ethanol in U.S. Gas Tanks is Backfiring for Climate Change

A team of researchers has concluded that for every three gallons of corn ethanol that’s being burned under America’s flagship renewable fuel rules, Americans will avoid burning just one gallon of gasoline made from crude. Their findings add to evidence that the mandated use of biofuels under the Renewable Fuel Standard, which was approved by… Read More

Study Finds Biofuels Worse for Climate than Gasoline

Study Finds Biofuels Worse for Climate than Gasoline

Years of number crunching that had seemed to corroborate the climate benefits of American biofuels were starkly challenged in a science journal on Thursday, with a team of scientists using a new approach to conclude that the climate would be better off without them. Based largely on comparisons of tailpipe pollution and crop growth linked to biofu… Read More

Biomass Power Slumps as EPA, Industry Spar on Science

Biomass Power Slumps as EPA, Industry Spar on Science

With the biomass power industry in financial tumult, its leaders are pinning hopes for revival on Congress’s potential willingness to interfere with climate science. The legislative language, introduced by some Republicans in the House and Senate and by a Democrat-aligned independent Senator, varies slightly. But it all requires that most wood… Read More

Europe Aims to Close Loophole on Wood Energy

Europe Aims to Close Loophole on Wood Energy

European officials are moving to close a loophole that promotes the burning of wood for electricity by an industry that’s felling American trees, and a new report they commissioned has laid bare the urgent need for reform.… Read More

Michigan Scientists See Urgency for Negative Emissions

Michigan Scientists See Urgency for Negative Emissions

Beyond Carbon Neutral at the University of Michigan is one of several university programs across the country investigating potential ways of taking large-scale negative emissions out of the theoretical realm and into the real.… Read More
