Adding up renewable energy

Do the overall efficiencies of renewable energy sources, such as wind, solar and geothermal add up in terms of their complete life cycle from materials sourcing, manufacture, running, and decommissioning? Researchers in Greece have carried out a life cycle assessment to find the answer.

   07-24-2007 · EurekAlert!
   Renewable does not mean green. That is the claim of Jesse Ausubel of the Rockefeller University in New York. Writing in Inderscience's International Journal of Nuclear Governance, Economy and Ecology, Ausubel explains that building enough wind farms, damming enough rivers, and growing enough biomass to meet global energy demands will wreck the environment.

6. All alone, ammonia and hydrogen chloride use negativity to get attached
   02-14-2008 · EurekAlert!
   Electrons can spur the chemical reaction between an acid and a base, according to new results in Science, a finding that may help researchers precisely control reactions in areas from biology to energy technology. By isolating one molecule each of hydrogen chloride and ammonia, the researchers found that by adding or removing one extra electron to this skeletal environment, they could make the reaction go from acid and base to neutral molecule or back again.

10. Power switch
    09-20-2007 · EurekAlert!
    The wisest energy strategy for the United States and other countries facing similar challenges is to move away from their reliance on large-scale centralized coal and nuclear plants, and instead, invest in renewable energy systems and small scale decentralized generation technologies. According to Benjamin Sovacool from the Virginia Polytechnic Institute and State University, these alternative technologies are simultaneously feasible, affordable, environmentally friendly, reliable and secure. His analysis is published in Springer's journal Policy Sciences.
