France has been held up, worldwide, as the forerunner in using nuclear fission to produce electricity. However, a third of the nation's nuclear reactors will need replacing in the next decade, and public opinion has shifted toward reducing reliance on nuclear power.
The Amazon rainforest, energy grids, and cells in the human body share a troublesome property: they possess multiple stable states. When the world's largest tropical forest suddenly starts retreating in a warming climate, energy supply blacks out, or cells turn carcinogenic, complex-systems science understands this as a transition between two such states.
In the wake of the Fukushima disaster, nuclear-dependent Japan began shutting down its other reactors. Toshiya Okamura, a Tokyo Gas executive and visiting scholar at Stanford University, explains how the country survived the summer, and expresses deep concerns about this winter and his country's energy future.
These projects use innovative synthetic biological and chemical techniques to convert biomass into processable sugars that can be transformed into bioproducts and drop-in biofuels for cars, trucks, and planes.
For almost 30 years, researchers have sought to identify a particular enzyme that is involved in regulating electron transport during photosynthesis. A team of scientists has now found the missing link, which turns out to be an old acquaintance.
The New York State Energy Research and Development Authority (NYSERDA) has awarded a total of $15 million to Columbia University, the Polytechnic Institute of New York University and High Tech Rochester to create three Proof-of-Concept Centers dedicated to helping inventors and scientists turn their high-tech, clean-energy ideas into successful businesses.
An efficient, robust, and compact wind power plant with a 10 MW superconducting generator is being developed by partners from industry and science within the recently established EU project SUPRAPOWER.
Amid growing concern over the surprisingly large amount of greenhouse gas produced by the Internet and other telecommunications activities, researchers are reporting new models of emissions and energy consumption that could help reduce their carbon footprint.
By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years, researchers based at the National Oceanography Centre, Southampton have found that greenhouse gas concentrations similar to the present (almost 400 parts per million) were systematically associated with sea levels at least nine metres above current levels.
The new monitoring will include not only PM2.5, but also sulfur dioxide, nitrogen dioxide, ozone and carbon monoxide, the Xinhua news agency said, citing a Friday announcement by the Ministry of Environmental Protection.
Industries across Europe are threatened as European Union emission rules for Volatile Organic Compounds are tightened. Now an aircleaning invention from the University of Copenhagen has proven its ability to remove these compounds.
