Climate impact of hydropower varies widely
13 Nov 2019 at 5:29am
Hydropower is broadly considered to be much more environmentally friendly than electricity generated from fossil fuels, and in many cases this is true. However, a new study reveals that the climate impact of hydropower facilities varies widely throughout the world and over time, with some facilities emitting more greenhouse gases than those burning fossil fuels.
Superconducting wind turbine chalks up first test success
12 Nov 2019 at 8:03am
A superconducting rotor has been successfully tested on an active wind turbine for the first time. The researchers designed, developed, manufactured a full-size superconducting generator for a 3.6 megawatt wind turbine, and field-tested it.
Study shows where global renewable energy investments have greatest benefits
12 Nov 2019 at 6:06am
New study finds that the amount of climate and health benefits achieved from renewable energy depends on the country where it is installed. Countries with higher carbon dioxide (CO2) emissions and more air pollution, such as India, China, and areas in Southeast Asia and Eastern Europe, achieve greater climate and health benefits per megawatt (MW) of renewable energy installed than those operating in areas such as North America, Brazil, and parts of Europe.
Where to install renewable energy in US to achieve greatest benefits
29 Oct 2019 at 5:07am
A new study shows that to achieve the biggest improvements in public health and the greatest benefits from renewable energy, wind turbines should be installed in the Upper Midwest and solar power should be installed in the Great Lakes and Mid-Atlantic regions.
To rid electric grid of carbon, shore up green energy support
28 Oct 2019 at 2:51pm
Engineers, along with an economist, have created an energy model that helps to remove carbon-generated power from the US electric grid -- replacing it with a greener, financially feasible wind, solar and hydro energy system.
Study casts doubt on carbon capture
25 Oct 2019 at 2:08pm
Current approaches to carbon capture can increase air pollution and are not efficient at reducing carbon in the atmosphere, according to new research.
Replacing coal with gas or renewables saves billions of gallons of water
21 Oct 2019 at 2:13pm
The transition from coal to natural gas in the US electricity sector is reducing the industry's water use, research finds. For every megawatt of electricity produced using natural gas instead of coal, the water withdrawn from rivers and groundwater drops by 10,500 gallons, and water consumed for cooling and other plant operations and not returned to the environment drops by 260 gallons. Switching to solar or wind power could boost these savings even more.
Computer models show clear advantages in new types of wind turbines
16 Oct 2019 at 9:45am
Researchers have modeled the fluid dynamics of multi-rotor wind turbines via high-resolution numerical simulations. The simulations demonstrate a clear advantage for a turbine model with four rotors. The researchers found, that the wind turbine wake recovers much faster with multi-rotor turbines, that multi-rotor turbines produce slightly more energy than single-rotor turbines, and that a turbine with four rotors as far apart as possible is the optimal construction.
Volleyball: The secret to sneaky float serves
10 Oct 2019 at 6:58am
A team of researchers performed wind tunnel experiments to determine the role of asymmetry caused by the orientation of a volleyball on its aerodynamic characteristics. They found that switching from the standard panel arrangement to a hexagonal or dimpled pattern may improve the consistency of flight, with many potential applications in aviation.
Model helps choose wind farm locations, predicts output
24 Sep 2019 at 12:13pm
The wind is always blowing somewhere, but deciding where to locate a wind farm is a bit more complicated than holding up a wet finger. Now a team of researchers has a model that can locate the best place for the wind farm and even help with 24-hour predictions of energy output.
New report deepens understanding of wind-wildlife interactions
23 Sep 2019 at 11:08am
An increase in the generation of wind energy is a key component of the U.S. strategy to reduce carbon emissions from the power sector. Approximately 97 gigawatts of wind energy production capacity are currently installed in the U.S., and in 2018, wind energy supplied about 6.5% of the nation's electricity. Scenarios developed by various groups, including U.S. Department of Energy, indicate that a four- to five-fold expansion over current levels of electricity produced by wind is needed by the year 2050 to help meet U.S. carbon emission reduction goals.
Europe has the untapped onshore capacity to meet global energy demand
14 Aug 2019 at 5:12am
Europe has the capacity to produce more than 100 times the amount of energy it currently produces through onshore windfarms, new analysis has revealed.
Growth of wind energy points to future challenges, promise
13 Aug 2019 at 8:22am
Advances in adapting the technology and better methods for predicting wind conditions have fanned significant growth of the use of wind turbines for electricity in the last 40 years. A new report takes stock of where the field is now and what lies ahead. Researchers surveyed the growth of wind technology as a source of renewable energy and assessed its viability for continuing to capture larger shares of the electricity market.
Installing solar panels on agricultural lands maximizes their efficiency
8 Aug 2019 at 9:38am
A new study finds that if less than 1% of agricultural land was converted to solar panels, it would be sufficient to fulfill global electric energy demand.
Supercomputers use graphics processors to solve longstanding turbulence question
25 Jul 2019 at 6:18am
Advanced simulations have solved a problem in turbulent fluid flow that could lead to more efficient turbines and engines.
