Satellite observations of global sea-surface temperature show that a 30-year upward trend has slowed down within the last 15 years. Climate scientists say this is not the end of global warming, but the result of a rearrangement in the energy flow of the climate system and, in particular, how the ocean stores heat.
The 2014 installment of the Sustainable Energy in America Factbook - produced for The Business Council for Sustainable Energy by Bloomberg New Energy Finance - has found that renewable energy, natural gas and energy efficiency advancements are leading a transformation of America's energy.
Extreme weather events like super-typhoon Haiyan and hurricane Sandy can have major negative impacts on the world economy. So far, however, the effects on global production and consumption webs are missing from most assessments.
While the debate over using crops for fuel continues, scientists are now reporting a new, fast approach to develop biofuel in a way that doesn't require removing valuable farmland from the food production chain. Their work examining the fuel-producing potential of Streptomyces, a soil bacterium known for making antibiotic.
Wastewater from pulp and paper mills contains large volumes of organic material that can be converted into biogas, according to findings by researchers from Water and Environmental Studies (WES) at Linköping University.
Gasoline-like fuels can be made from cellulosic materials such as farm and forestry waste using a new process invented by chemists at the University of California, Davis. The process could open up new markets for plant-based fuels, beyond existing diesel substitutes.
A breakthrough in the use of renewable raw materials in chemical production has been achieved by Karlsruhe Institute of Technology (KIT) and its industrial partner AVA Biochem. The partners developed an innovative hydrothermal method to obtain the organic compound from biomass. Being a platform chemical, 5-HMF can serve as a precursor for various materials.
Last week, the European Commission presented a new action plan to facilitate the further development of the renewable ocean energy sector in Europe. A central element in this action plan will be to establish an Ocean Energy Forum, bringing together stakeholders to build capacity and foster cooperation.
A 3-million dollar grant from the U.S. Department of Energy will allow a University of Oklahoma multi-disciplinary research team to develop a novel biomass conversion process to obtain a bio-oil compatible with refinery operations.
