Making wind farms more efficient
9 Nov 2018 at 9:26am
With energy demands rising, researchers have completed an algorithm -- or approach -- to design more efficient wind farms, helping to generate more revenue for builders and more renewable energy for their customers.
Solar power: largest study to date discovers 25 percent power loss across UK
9 Nov 2018 at 7:14am
Regional 'hot spots' account for the power slump and these are more prevalent in the North of England than in the south.
Harvesting renewable energy from the sun and outer space at the same time
8 Nov 2018 at 11:24am
Scientists have demonstrated for the first time that heat from the sun and coldness from outer space can be collected simultaneously with a single device. Their research suggests that devices for harvesting solar and space energy will not compete for land space and can actually help each other function more efficiently.
Images of photosynthetic protein complex splitting water
7 Nov 2018 at 10:38am
In a new article presents high-resolution images of photosystem II, the protein complex that splits water into hydrogen ions and oxygen during photosynthesis. The images will help researchers better understand this complex mechanism, possibly opening up the door to developing cheap and efficient solar fuel devices.
Magnetic pumping pushes plasma particles to high energies
5 Nov 2018 at 7:54am
The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists now have a new idea about what heats the solar wind, a theory called magnetic pumping.
A carbon neutral solution for desalination? Maybe so by tapping into geothermal
5 Nov 2018 at 6:17am
Water shortages are hitting some areas of the world hard, and with increasing global temperatures, more regions may be experiencing drought conditions.
Modelling a future fuelled by sustainable energy
30 Oct 2018 at 6:36am
Economists have modeled the transition from a world powered by fossil fuels to one in which sustainable sources supply all our energy needs.
A solar cell that does double duty for renewable energy
29 Oct 2018 at 10:10am
Researchers have developed an artificial photosynthesis device called a ''hybrid photoelectrochemical and voltaic (HPEV) cell'' that turns sunlight and water into two types of energy - hydrogen fuel and electricity.
Coal power plant regulations neglect a crucial pollutant
29 Oct 2018 at 10:10am
Researchers determine that particle-forming sulfur dioxide is the most damaging pollutant from Texas' coal-fired power plants that lack equipment to scrub emissions.
New material, manufacturing process use sun's heat for cheaper renewable elec...
18 Oct 2018 at 9:51am
Scientists have developed a new material and manufacturing process that would make one way to use solar power -- as heat energy -- more efficient in generating electricity.
Wind farms and reducing hurricane precipitation
17 Oct 2018 at 11:10am
New research reveals an unexpected benefit of large-scale offshore wind farms: the ability to lessen precipitation from hurricanes.
Renewable energy is common ground for Democrats and Republicans
16 Oct 2018 at 11:24am
While conservatives and liberals tend to disagree on many environmental issues, they both view the development of solar power and other forms of renewable energy as financially savvy and a step towards self-sufficiency.
New technique for turning sunshine and water into hydrogen fuel
11 Oct 2018 at 7:36am
Researchers have developed new photocatalyst synthesis method using Magnesium hydride (MgH2) and Titanium dioxide (TiO2). The result is expected to contribute to hydrogen mass production through the development of photocatalyst that reacts to solar light.
Windier wind farms
4 Oct 2018 at 10:18am
Depending on how wind turbines are situated relative to each other and to the prevailing wind, those not directly in the path of the wind could be left to extract energy from significantly depleted airflow. However, according to researchers, there are ways to get around this issue of diminishing wind returns.
Large-scale US wind power would cause warming that would take roughly a centu...
4 Oct 2018 at 8:25am
Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. Researchers report the most accurate modelling yet of how increasing wind power would affect climate, finding that large-scale wind power generation would warm the Continental United States 0.24 degrees Celsius because wind turbines redistribute heat in the atmosphere.
