A formula to increase wind turbines’ efficiency level

September 11th, 2009 WASHINGTON - In a new research, scientists have estimated that wind alone has the potential to meet China's electricity demands projected for 2030. The research, carried out by environmental scientists from Harvard and Tsinghua University, demonstrated the enormous potential for wind-generated electricity in China.

September 10th, 2009 Study: Wind could cut China's emissions by 30 pctBEIJING — China could cut its emissions by 30 percent in the next two decades if it switches to wind power to meet about half of its electricity demands, a U.S. study published Thursday said.

September 8th, 2009 WASHINGTON - Americans used more solar, nuclear, biomass and wind energy in 2008 than they did the year before, according to latest energy flow charts released by Lawrence Livermore National Lab (LLNL). The US used less coal and oil during the same time frame and only slightly increased its natural gas consumption.

September 7th, 2009 LONDON - The results of a new study indicate that winds turbines might be hastening the local extinction of an endangered vulture in southern Spain. Studies have so far focused on the short-term effects of wind turbines, looking at the number of bird collisions per turbine per year.

July 14th, 2009 SYDNEY - Effective glazing of windowpanes may reduce the growing reliance on energy-gobbling airconditioners, says a researcher at Queensland University of Technology (QUT). John Bell, professor at the QUT Institute of Sustainable Resources, has found how different window glass options can increase the energy efficiency of houses and decrease carbon emissions, saving money too.

June 10th, 2009 Congress abandoning Obama clean energy goalsWASHINGTON — Congress is all but abandoning President Barack Obama's goal of producing fully one-quarter of the nation's electricity from renewable sources — wind, solar and the like — by 2025, though a push for at least some increase is making headway. Both the House and Senate are considering legislation that would establish the first national requirement for electric utilities to generate a certain percentage of their power from renewable energy — from wind turbines and solar cells to biomass and geothermal sources.

May 28th, 2009 WASHINGTON - Researchers in the US have said that wind turbines of the future could incorporate shape-shifting blades that make them efficient at generating electricity at any wind speed. According to a report in Discovery News, these smart wind turbines would not only maximize the amount of electricity generated by wind power, but also extend their life span.

May 1st, 2009 WASHINGTON - A researcher at Purdue University has found a novel way to detect trace amounts of melamine in infant formula. With the help of infrared lasers and light spectroscopy methods, Lisa Mauer, an associate professor of food science, was able to detect melamine in baby formula at one part per million in about five minutes or less.

May 1st, 2009 WASHINGTON - Infrared lasers have helped researchers detect minute traces of a synthetic chemical like melamine in baby formula, within minutes. Melamine, used in plastics and other products, has been found in baby formula and other milk-based products imported from China.

April 22nd, 2009 Obama heads to Iowa for Earth DayWASHINGTON — President Barack Obama is going on the road to pitch his energy plan — as well as environmentally friendly jobs production — in a hard-hit Iowa town, while administration officials make a similar push back in Washington. The White House's Earth Day message comes as Obama has watched his energy legislation slow in Congress.

April 21st, 2009 High cost of addressing climate change challengedWASHINGTON — An environmental group is challenging claims that major reductions in greenhouse gases would lead to soaring energy costs. The Union of Concerned Scientists says its analysis, using Energy Department computer models, show that higher electric and gasoline costs will be offset by improvements in energy and automobile efficiency.

March 25th, 2009 WASHINGTON - Researchers at the Georgia Institute of Technology have developed a surface treatment that boosts the light absorption of silicon photovoltaic cells in two complementary ways. The surface treatment increases absorption both by trapping light in three-dimensional structures and by making the surfaces self-cleaning - allowing rain or dew to wash away the dust and dirt that can accumulate on photovoltaic arrays.

March 13th, 2009 WASHINGTON - A new research has indicated that with adequate financial and political support, renewable energy technologies like wind and photovoltaics could supply 40 percent of the world's electricity by 2050. This research was presented at a press conference by Peter Lund of the Helsinki University of Technology's Advanced Energy Systems in Espoo, Finland, ahead of the scheduled congress session titled, "Renewable Energies: How Far Can They Take Us?" "Our findings demonstrate that with global political support and financial investment, previous notions that the potential for renewables was in some way limited to a negligible fraction of world demand were wrong," said Lund.
