As the race to develop a permanent sustainable aviation fuel (SAF) that will eventually replace kerosene continues, two new developments shed light on how quickly the technology is advancing. A company called Enviva, which is touted as the world’s largest producer of biomass, has invested in biomass factories all throughout the southeastern U.S. These factories […]
Costa Rica has charted another clean energy accolade. So far this year, the Central American country has run on 300 days of 100 percent power generation from renewable energy sources, according to the Costa Rican Institute of Electricity (ICE), which cited figures from the National Center for Energy Control. With six weeks left of 2017 […]
A new study published Wednesday in the journal PLOS ONE adds more evidence that insect populations around the globe are in perilous decline. For the study, researchers from Radboud University in the Netherlands, alongside their German and English colleagues, measured the biomass of trapped flying insects at 63 nature preserves in Germany since 1989. They […]
By Sami Yassa A pre-eminent think tank in the United Kingdom, Chatham House, issued a seminal report last week challenging a fundamental assumption underlying European renewable energy policy: that burning forest biomass to produce electricity is “carbon neutral.” The report, Woody Biomass for Power and Heat: Impacts on the Global Climate, finds that many forms […]
The Himalayan Mountains and Tibetan Plateau, dubbed the “Third Pole” for having the largest ice mass on Earth after the polar regions, are rapidly losing their glaciers. Eighteen percent of China’s glaciers have vanished in the past 50 years according to the Chinese Academy of Sciences. Air pollution and rising air temperatures are combining to […]
The shift from fossil fuels to renewable energy is occurring mainly at the power plant level. But what about transportation? Can we significantly reduce greenhouse gas emissions by switching to cleaner fuels? Or is this just an attempt to keep 20th century technology chugging along while trading one set of environmental problems for another? Biofuels […]
