• There is enough wind power to meet global energy demand

    There is enough energy available in winds to meet all of the world’s demand; atmospheric turbines that convert steadier and faster high-altitude winds into energy could generate even more power than ground- and ocean-based units

  • Predicting waves’ height, force could double marine-based energy

    In the search for alternative energy, scientists have focused on the sun and the wind; there is also tremendous potential in harnessing the power of the ocean’s waves, but marine energy presents specific challenges that have made it a less promising resource; one of these challenges is the fact that waves differ in terms of their size and force; forecasting wave height one second in advance optimizes energy collection

  • Innovative hydroelectric solution harvests power from water flowing through municipal pipes

    An innovative solution has made it so dams do not have to be built in order to get hydroelectricity; hydroelectric power can now be harvested from water flowing through municipal pipes; the innovation is creating energy by using existing infrastructure, as well as solving a problem in that infrastructure

  • Engineers develop electricity-free home cooling system

    Researchers are developing a solar cooling and heating system for the home which will run independently of the electricity grid and generate domestic hot water as a by-product

  • Mystery of dramatic leveling off of methane in the atmosphere solved

    Increased capture of natural gas from oil fields probably accounts for up to 70 percent of the dramatic leveling off seen in atmospheric methane at the end of the twentieth century; methane has twenty times the global warming potential of carbon dioxide, although CO2 is filling the atmosphere in far larger amounts

  • Engineering students build U.K. first hydrogen powered locomotive

    Engineering students and staff at the University of Birmingham have designed and built a prototype hydrogen powered locomotive, the first of its kind to operate in the United Kingdom

  • Future increases in U.S. natural gas exports may not be as large as thought

    Amid policy debate over potential liquefied natural gas (LNG) exports from the United States, a new study predicts the long-term volume of exports from the United States will not likely be very large; the paper also argues that the impact on U.S. domestic natural gas prices will not be large if exports are allowed by the U.S government

  • New process doubles production, slashes costs of butanol

    Butanol has a 30 percent higher energy content than ethanol, lower vapor pressure, and is less volatile, less flammable, and mixes well with gasoline; a new discovery should make butanol more attractive to the biofuel industry

  • Farmers upset by plan for water banking system

    Depending on the depth of the drilling, it can take anywhere from two gallons to two million gallons of water to frack one well; drilling companies consumeenough water in their fracking operations to meet the needs of between 66,400 and 118,000 households; in the parched Midwest, farmers raise questions about water-use priorities

  • Wind farms pose risks to ultra-light aircraft

    Airfields for ultra-light aircraft are typically constructed on level ground — and so are wind farms; do wind power plants generate turbulence that could endanger lightweight planes? A simulation can compute how these power plants influence aircraft at various wind speeds and wind directions

  • Study finds correlation between injection wells and small earthquakes

    Most earthquakes in the Barnett Shale region of North Texas occur within a few miles of one or more injection wells used to dispose of wastes associated with petroleum production such as hydraulic fracturing fluids, according to new research

  • Improving oil recovery, aiding environmental cleanup

    Researchers have taken a new look at an old, but seldom-used technique developed by the petroleum industry to recover oil, and learned more about why it works, how it could be improved, and how it might be able to make a comeback not only in oil recovery but also environmental cleanup

  • A second look at off-shore use of vertical-axis wind turbines

    Wind energy researchers are re-evaluating vertical axis wind turbines (VAWTs) to help solve some of the problems of generating energy from offshore breezes; though VAWTs have been around since the earliest days of wind energy research, VAWT architecture could transform offshore wind technology

  • Conflict of interests charges surround two pro-fracking studies

    Two recent studies — by research institutes at  the University of Buffalo and the University of Texas — on the relationship between fracking and the contamination of groundwater, offered what was claimed to be scientific, peer-reviewed research which concluded that fracking does not contribute to such contamination; an examination of the two reports reveals that they were not properly reviewed according to accepted academic standards, and that their authors, and the research institutes which sponsored them, are heavily involved with companies which conduct fracking operations; the author of the University of Texas report sits on the board of a leading fracking company, where his compensation is more than twice as large as his UT salary; he did not disclose this fact in the study — or inform UT of this connection; UT is investigating

  • Replacing coal with natural gas would reduce global warming

    A new study finds that a gas substitution scenario, in which natural gas replaces all coal power production and any new oil-powered facilities by midcentury, would realize 40 percent of the reduction in global warming that could be achieved with a full switch to low-carbon fuel sources; this is a less costly, and more feasible, option, than switching all electricity generation immediately and aggressively to non-fossil fuel sources such as solar, wind, and nuclear
