Researchers from North Carolina State University have developed a new technique that allows users to better determine the amount of charge remaining in a battery in real time. That?s good news for electric vehicle drivers, since it gives them a better idea of when their car may run out of juice.
Americans used less energy in 2011 than in the previous year due mainly to a shift to higher-efficiency energy technologies in the transportation and residential sectors. Meanwhile, less coal was used but more natural gas was consumed according to the most recent energy flow charts released by Lawrence Livermore National Laboratory.
Demand for palm oil is driving the deforestation of forests in Borneo, as trees are cleared to make way for the planting of oil farm plantations, which will send carbon dioxide, a global-warming gas, into the atmosphere.
Controlling "mixing" between acceptor and donor layers, or solar cell domains, in polymer-based solar cells could increase their efficiency, according to a team of researchers that included physicists from North Carolina State University. Their findings shed light on the inner workings of these solar cells, and could lead to further improvements in efficiency.
New research from Carnegie's Ken Caldeira examines the limits of the amount of power that could be harvested from winds, as well as the effects high-altitude wind power could have on the climate as a whole.
A cost analysis of the technologies needed to transport materials into the stratosphere to reduce the amount of sunlight hitting Earth and therefore reduce the effects of global climate change has shown that they are both feasible and affordable.
Scientists today unveiled new technology intended to move soybeans, second only to corn as the top food crop in the U.S., along that same use-to-all path as a raw material for a wider portfolio of products.
With enough sunlight falling on home roofs to supply at least half of America's electricity, scientists have described advances toward the less-expensive solar energy technology needed to roof many of those homes with shingles that generate electricity.
