Study shows where global renewable energy investments have greatest benefits

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. … read more

To rid electric grid of carbon, shore up green energy support

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. … read more

Replacing coal with gas or renewables saves billions of gallons of water

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 For every megawatt of electricity produced using natural gas instead of coal, the water withdrawn from rivers and groundwater drops by 10,500 gallons, and water consumed for cooling and other plant operations and not returned to the environment drops by 260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. … read more

Computer models show clear advantages in new types of wind turbines

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. … read more

Climate Change Policy Measures: Identifying Priorities, Particularly Outside of the Usual Suspects

With the 2020 Presidential race already heating up, issues surrounding climate change, clean energy, and what policy mechanisms are the most critical ones for the federal government to employ are getting more of a spotlight than ever before. While ideas like research & development, tax credits, and carbon prices are among the first policy levers […]

Volleyball: The secret to sneaky float serves

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. … read more

Model helps choose wind farm locations, predicts output

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. … read more

New report deepens understanding of wind-wildlife interactions

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. … read more

Does the U.S. Still Need the Solar Investment Tax Credit?

Over the last 10 years, the Solar Investment Tax Credit (ITC), which offers a federal income tax credit worth 30% of a homeowner’s solar installation costs, has opened up solar to millions of homeowners by dropping that huge financial hurdle. But the ITC is set to begin phasing out at the end of 2019 and […]
