U.S. Energy Use Declines in 2015, Renewables Gain

(DoDLive.mil)

20 April 2016. Energy use by Americans in their homes and businesses declined in 2015 from the previous year, due to a sharp drop in coal burned for electric power, among other factors. The findings were published in an annual accounting of national energy supply and demand by Lawrence Livermore National Laboratory, based . . . → Read More: U.S. Energy Use Declines in 2015, Renewables Gain

What it Takes to Innovate in the Old Economy

Richard van Atta (A. Kotok)

12 February 2016. Innovation is important throughout the modern economy, particularly in established industries that may lack the excitement of hot new sectors like biotechnology. A panel at the American Association for the Advancement of Science, or AAAS 2016 annual meeting today (12 February) in Washington, D.C. examined ways . . . → Read More: What it Takes to Innovate in the Old Economy

Solar Process Converts CO2 to Source of Power, Chemicals

Andrew Bocarsly (Brian Wilson, Princeton University)

2 July 2014. Chemists from Princeton University and spin-off company Liquid Light Inc. in Monmouth Junction, New Jersey created a process to use sunlight for converting carbon dioxide into formic acid, a source for electric power and industrial chemicals. Princeton chemistry professor Andrew Bocarsly, also a founder of . . . → Read More: Solar Process Converts CO2 to Source of Power, Chemicals
