In 2012, wind energy became the number one source of new U.S. electricity generation capacity for the first time - representing 43 percent of all new electric additions and accounting for $25 billion in U.S. investment.
Researchers describe a novel process to cut down on heat loss during the winter and keep buildings cool during the summer. Their 'bio-inspired approach to thermal control for cooling (or heating) building window surfaces' calls for attaching optically clear, flexible elastomer sheets, bonded to regular glass window panes.
The overall aim of the EU-funded CLIMSAVE project, ('Climate change integrated assessment methodology for cross-sectoral adaptation and vulnerability in Europe'), is to help in the assessment of the impact of climate change over a range of environmental and economic areas in different regions.
Although e-vehicles make up only a tiny fraction of the European car fleet at present, sales are expected to grow exponentially over the coming years, thanks, in no small measure, to advances in e-vehicle technology.
A University of Colorado Boulder team has developed a radically new technique that uses the power of sunlight to efficiently split water into its components of hydrogen and oxygen, paving the way for the broad use of hydrogen as a clean, green fuel.
A technique for trapping the greenhouse gas carbon dioxide deep underground could at the same be used to release the last fraction of natural gas liquids from ailing reservoirs, thus offsetting some of the environmental impact of burning fossil fuels.
Using a simple solar cell and a photo anode made of a metal oxide, scientists have successfully stored nearly five percent of solar energy chemically in the form of hydrogen. This is a major feat as the design of the solar cell is much simpler than that of the high-efficiency triple-junction cells based on amorphous silicon or expensive III-V semiconductors that are traditionally used for this purpose.
