NASA researchers have begun a series of flights using the agency's DC-8 flying laboratory to study the effects of alternate biofuel on engine performance, emissions and aircraft-generated contrails at altitude.
Ford's new five-year global waste reduction strategy calls for a 40 percent per vehicle reduction in the amount of waste sent to landfill between 2011 and 2016 - equal to just 13.4 pounds per vehicle worldwide.
Agriculture is responsible for around ten to twelve percent of all greenhouse gases attributable to human activities. This raises the question of how these emissions could be reduced. A recent study has investigated - for the first time - the full range of factors that contribute to greenhouse gas emissions, namely soil and climate conditions, the agricultural model and the farming intensity on both organic and conventional holdings.
Scientists have established that an electron beam can be accelerated by a laser in free space. This has never been done before at high energies and represents a significant breakthrough. It also may have implications for fusion as a new energy source.
First Solar, Inc. announced it set a new world record for cadmium-telluride (CdTe) photovoltaic solar cell conversion efficiency, achieving 18.7 percent cell efficiency in tests confirmed by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL).
A new study shows that reaching the 3 energy-related objectives proposed by the United Nations in their Sustainable Energy for All (SE4All) initiative, launched in 2011, would reduce emissions of greenhouse gases that contribute to climate change and, in combination with other measures, could help keep global temperature rise from exceeding the internationally agreed target level of 2 C.
