Profile
The National Science Foundation is an independent U.S. federal agency established by Congress in the NSF Act of 1950 "to promote progress of science," and "advance national health, prosperity, and welfare," and "to secure the national defense." NSF provides financial support for fundamental research and education across all fields of science and engineering. The majority of the funds are provided to support basic research performed in U.S. academic institutions.

Electric drive vehicles have little impact on U.S. pollutant emissions
A new study from North Carolina State University indicates that even a sharp increase in the use of electric drive passenger vehicles (EDVs) by 2050 would not significantly reduce emissions of high-profile air pollutants carbon dioxide, sulfur dioxide or nitrogen oxides.22 Jan 2014
Organic mega flow battery promises breakthrough for renewable energy
A team of scientists and engineers has demonstrated a new type of battery that could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and solar far more economical and reliable.22 Jan 2014
How to tap the sun's energy through heat as well as light
