Restricting nuclear power has little effect on the cost of climate policies

October 2, 2012 9:03 am | News | Comments

Applying a global energy-economy computer simulation that fully captures the competition between alternative power supply technologies, a team of scientists from the Potsdam Institute for Climate Impact Research and the University of Dayton, Ohio, analyzed trade-offs between nuclear and climate policies. They found that incremental costs due to policy options restricting the use of nuclear power do not significantly increase the cost of even stringent greenhouse-gas emissions reductions.

Study: Solar and wind energy may stabilize the power grid

September 14, 2012 8:49 am | News | Comments

If increasing numbers of wind turbines and photovoltaic systems feed electrical energy into the energy grid, it becomes denser—and more distributed. Researchers in Germany, using model simulations, have discovered that consumers and decentralized generators can easily self-synchronize. Their results indicate that a failure of an individual supply line in the decentralized grid less likely implies an outage in the network as a whole. But care must be taken when adding new lines.

According to data from a 2008 Business R&D and Innovation Survey by the National Science Foundation, businesses perform the lion's share of their R&D activity in just a small number of geographic areas, particularly the San Jose-San Francisco-Oakland area and the New York-Newark-Bridgeport area.

Computerized house to generate as much energy as it uses

September 13, 2012 4:11 am | News | Comments

NIST unveiled a new laboratory designed to demonstrate that a typical-looking suburban home for a family of four can generate as much energy as it uses in a year. Following an initial year-long experiment, the facility will be used to improve test methods for energy-efficient technologies and develop cost-effective design standards for energy-efficient homes that could reduce overall energy consumption and harmful pollution, and save families money on their monthly utility bills.

Two-faced materials boost hydrogen production

September 12, 2012 9:48 am | News | Comments

Though costly to produce, hydrogen is crucial for the oil-refining industry and the production of essential chemicals such as the ammonia used in fertilizers. The recent invention of a new photocatalyst may help the efficiency of this process. Nanometer-scale “Janus” structures consisting of cheap metal and oxide spheres were recently demonstrated as an excellent catalyst for a hydrogen-production reaction powered only by sunlight.
