Stable power supply thanks to wind turbines
Wind turbines can help keep the voltage in the electricity network at a constant level. The power electronics in the turbines can effectively correct peaks and dips in the mains voltage. This is the conclusion reached by NWO-funded researchers. Modern wind turbines are a good means of coping with fluctuations in the mains voltage. Such... view more... (2001-10-08)
'Beyond Einstein' research should begin with mission to study dark energy
NASA and the U.S. Department of Energy should pursue the Joint Dark Energy Mission (JDEM) as the first mission in the "Beyond Einstein" program, according to a new report from the National Research Council. view more (2007-09-07)
From campfire to gas tank, Mesquite energy may be harvested for ethanol
The dense mesquite-covered mid-section of Texas could provide fuel for about 400 small ethanol plants, according to one Texas Agricultural Experiment Station researcher. view more (2006-06-23)
Strength training combined with a low energy diet best for obese kids
A low energy diet combined with strength training seems the best way of tackling childhood obesity, shows research in the Archives of Disease in Childhood. view more (2002-05-20)
MIT creates new material for fuel cells
MIT engineers have improved the power output of one type of fuel cell by more than 50 percent through technology that could help these environmentally friendly energy storage devices find a much broader market, particularly in portable electronics. view more (2008-05-16)
Hurricanes, other vortices seize energy via 'hostile takeovers'
For decades, scientists who study hurricanes, whirlpools and other large fluid vortices have puzzled over precisely how these vast swirling masses of gas or liquid sustain themselves. view more (2006-03-07)
Waste not, want not
Tapping industrial waste heat could reduce fossil fuel demands in the short term and improve efficiency of countless manufacturing processes, according to scientists in Japan writing in the International Journal of Exergy. view more (2009-04-02)
University helps reduce poverty through renewable energy
With the spotlight on World Summit on Sustainable Development in Johannesburg, the issue of fossil fuel use has become a pressing one. According to renewable energy specialists at Sheffield Hallam University, fossil fuels have only benefited the development of two thirds of the world’s population and the need to take advantage of already... view more...

Further commitment to sustainable power generation
A further £10M for research into renewable energy technologies Following the Government's "Energy Review" a further £10M is being put into research into renewable energy technology. The kind of work being invested in will include: Power distribution networks - ensuring a high quality, reliable supply of electricity. Marine... view more... (2002-05-31)
Researcher discovers new materials
A research team led by Carnegie Mellon University Materials Science and Biomedical Engineering Professor Prashant Kumta has discovered a nanocrystalline material that is cheaper, more stable and produces a higher quality energy storage capacity for use in a variety of industrial and portable consumer electronic products. view more (2006-07-11)
Geologist troubleshoots silica problem at geothermal plants
In the debate over alternative energy resources, geothermal technology has received scant media attention. Advocates call it one of the cleanest, sustainable energy resources available. However, steep construction, equipment and drilling costs have prevented more widespread development of geothermal technology. view more (2007-03-14)
UW-Madison engineers develop higher-energy liquid-transportation fuel from sugar
Plants absorb carbon dioxide from the air and combine it with water molecules and sunshine to make carbohydrate or sugar. Variations on this process provide fuel for all of life on Earth. view more (2007-06-21)
Flower power
A plastic "energy flower'' that collects solar and wind energy that can then be used to power appliances in the home for free has won a Northumbria University student a top award. Paul Richardson, a third year design student, won a £1,750 Design International Attachment Award from the RSA (Royal Society for the encouragement of Arts,... view more... (2002-05-24)
Supercomputer could throw light on 'mysterious' dark energy
Cosmologists have run a series of huge computer simulations of the Universe that could ultimately help solve the mystery of dark energy. view more (2008-01-11)
Making Wind Power More Efficient
A University of Ulster researcher has come up with a new method, using Artificial Intelligence techniques, to forecast wind energy more accurately than ever before. Predicting how fast the wind will blow has always been a major problem for wind farm operators. It is essential that they have some idea of how much electricity they will be able to... view more...
