Quadrupling turbines, US can meet 2030 wind-energy goals
24 Feb 2020 at 3:34pm
The United States could generate 20% of its electricity from wind within 10 years, without requiring any additional land, according to new research.
Could water solve the renewable energy storage challenge?
19 Feb 2020 at 12:28pm
Seasonally pumped hydropower storage could provide an affordable way to store renewable energy over the long-term, filling a much needed gap to support the transition to renewable energy, according to a new study.
An early warning system for damage in composite materials
18 Feb 2020 at 3:22pm
A team has developed a tool to monitor changes in widely used composite materials known as fiber reinforced polymers (FRPs), which can be found in everything from aerospace and infrastructure to wind turbines. The new tool, integrated into these materials, can help measure the damage that occurs as they age.
New bio-inspired wing design for small drones
29 Jan 2020 at 11:33am
Taking a cue from birds and insects, researchers have come up with a new wing design for small drones that helps them fly more efficiently and makes them more robust to atmospheric turbulence.
Consider marine life when implementing offshore renewable power
17 Dec 2019 at 8:42am
With countries adopting green energy practices, renewable energy now accounts for a third of the world's power. As this trend continues, more countries are looking to offshore energy sources to produce this renewable energy. Researchers identify situations where green technology such as wind turbines, wave energy converters, and other marine renewable energy devices (MREDs) have had negative consequences on marine life.
Supporting structures of wind turbines contribute to wind farm blockage effect
12 Dec 2019 at 7:46am
Much about the aerodynamic effects of larger wind farms remains poorly understood. New work looks to provide more insight in how the structures necessary for wind farms affect air flow. Using a two-scale coupled momentum balance method, researchers theoretically and computationally reconstructed conditions that large wind farms might face in the future, including the dampening effect that comes with spacing turbines close to one another.
Insects' drag-based flight mechanism could improve tiny flying robots
10 Dec 2019 at 8:17am
Thrips don't rely on lift in order to fly. Instead, the tiny insects rely on a drag-based flight mechanism, staying afloat in airflow velocities with a large ratio of force to wing size. Researchers have performed the first test of drag force on a thrip's wing under constant airflow in a bench-top wind tunnel and, drawing from microfabrication and nanomechanics, they created an experiment in which a thrip's wing was glued to a self-sensing microcantilever.
Biodiversity and wind energy
27 Nov 2019 at 9:13am
The location and operation of wind energy plants are often in direct conflict with the legal protection of endangered species. The almost unanimous opinion of experts from local and central government authorities, environmental NGOs and expert offices is that the current mechanisms for the protection of bats in wind power projects are insufficient.
Wind more effective than cold air at cooling rooms naturally
20 Nov 2019 at 9:11am
The effectiveness of non-mechanical, low-energy methods for moderating temperature and humidity has been evaluated in a series of experiments.
Decarbonizing the power sector
19 Nov 2019 at 4:53am
Electricity supply is one of the biggest CO2 emitters globally. To keep global warming well below 2°C, several paths lead to zero emissions in the energy sector, and each has its potential environmental impacts -- such as air and water pollution, land-use or water demand. Using a first-time combination of multiple modelling systems, an international team of researchers has now quantified the actual benefits and downsides of three main roads to decarbonization.
Boosting wind farmers, global winds reverse decades of slowing and pick up speed
19 Nov 2019 at 4:53am
In a boon to wind farms, average daily wind speeds are picking up across much of the globe after about 30 years of gradual slowing. Research shows that wind speeds in northern mid-latitude regions have increased by roughly 7% since 2010.
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.
