Residential coal use in China results in many premature deaths, models indicate
12 May 2021 at 5:34am
Coal combustion by power plants and industry pollutes the air, causing many governments to implement mitigation actions and encourage cleaner forms of energy. Now, a new study indicates that in China, indoor air pollution from residential coal burning causes a disproportionate number of premature deaths from exposure to tiny, inhalable pollutants.
Quantum mechanics paves the way for more stable organic solar cells
11 May 2021 at 9:35am
Quantum mechanics can be used to create more stable and more easily produced organic solar cells.
Chill out: Advanced solar tech runs cooler and lasts longer
10 May 2021 at 7:43am
New mechanisms for converting sunlight to electricity more efficiently are also beneficial for extending the lifespan of solar panels.
Hydrogen instead of electrification? Potentials and risks for climate targets
6 May 2021 at 11:21am
Hydrogen-based fuels should primarily be used in sectors such as aviation or industrial processes that cannot be electrified, finds a team of researchers. Producing these fuels is too inefficient, costly and their availability too uncertain, to broadly replace fossil fuels for instance in cars or heating houses. For most sectors, directly using electricity for instance in battery electric cars or heat pumps makes more economic sense.
Roadmap to expand NY solar energy, meet green goals
6 May 2021 at 7:53am
Solar-power developers need to explore using lower-quality agricultural land for solar energy, incentivize dual-use (combined agriculture and solar) options, avoid concentrated solar development and engage communities early to achieve New York's green energy goals, according to recent research.
Defect that limits hybrid perovskites solar-cell performance identified
30 Apr 2021 at 6:31am
Researchers have uncovered a major cause of limitations to efficiency in a new generation of solar cells.
New optical hydrogen sensors eliminate risk of sparking
29 Apr 2021 at 9:34am
A new study documents an inexpensive, spark-free, optical-based hydrogen sensor that is more sensitive -- and faster -- than previous models.
Combining solar panels and lamb grazing increases land productivity, study finds
29 Apr 2021 at 9:34am
Land productivity could be greatly increased by combining sheep grazing and solar energy production on the same land, according to new research.
Incentives could turn costs of biofuel mandates into environmental benefits
27 Apr 2021 at 10:55am
Researchers examined the economic and environmental costs of the Renewable Fuels Standard mandates through 2030, including the impact on water quality in the Mississippi River basin and Gulf of Mexico. Models showed maintaining the corn ethanol mandate will lead to substantial social and environmental costs because it incentivizes expanded corn production. But the cellulosic ethanol mandate can provide an overall benefit with the right performance-based policies.
Solar-powered desalination unit shows great promise
27 Apr 2021 at 9:24am
Freshwater accounts for only about 2.5% of water on Earth, so much of the world experiences serious water shortages. Scientists report the development of a highly efficient desalination device that uses a titanium-containing layer capable of absorbing solar energy. When sunlight strikes the layer, it heats rapidly and vaporizes the water. By placing the unit in a transparent container with a sloped quartz roof, the water vapor can be condensed and collected.
The new EU climate target could phase out coal power in Europe as early as 2030
27 Apr 2021 at 6:48am
Tightening the EU emissions trading system (EU ETS) in line with the EU Green Deal would dramatically speed up the decarbonization of Europe's power sector - and likely cause a demise of the coal industry.
Vertical turbines could be the future for wind farms
27 Apr 2021 at 5:57am
The now-familiar sight of traditional propeller wind turbines could be replaced in the future with wind farms containing more compact and efficient vertical turbines. New research has found that the vertical turbine design is far more efficient than traditional turbines in large scale wind farms, and when set in pairs the vertical turbines increase each other's performance by up to 15%.
Airports could generate enough solar energy to power a city
26 Apr 2021 at 11:08am
New research shows placing solar panels on the roofs of Australian airport buildings could be an efficient step towards net zero emissions.
Ten ways to ensure bees benefit from the solar power boom
20 Apr 2021 at 9:14am
Researchers assessing the impact of solar energy development across Europe have come up with ten ways in which the expansion of solar can be shaped to ensure pollinators benefit.
Experts' predictions for future wind energy costs drop significantly
15 Apr 2021 at 8:41am
Technology and commercial advancements are expected to continue to drive down the cost of wind energy, according to a new survey. Experts anticipate cost reductions of 17%-35% by 2035 and 37%-49% by 2050, driven by bigger and more efficient turbines, lower capital and operating costs, and other advancements.
