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...

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.
Emissions-free energy system saves heat from the summer sun for winter
3 Oct 2018 at 6:03am
Researchers have made strides towards the development of a specially designed molecule which can store solar energy for later use.
Artificial leaf: Highly active organic photocatalyst discovered
1 Oct 2018 at 10:03am
Scientists have synthesized a new organic material that can convert water into hydrogen fuel using sunlight.
Eco-friendly nanoparticles for artificial photosynthesis
1 Oct 2018 at 7:19am
Researchers have developed a nanoparticle type for novel use in artificial photosynthesis by adding zinc sulfide on the surface of indium-based quantum dots. These quantum dots produce clean hydrogen fuel from water and sunlight -- a sustainable source of energy. They introduce new eco-friendly and powerful materials to solar photocatalysis.
Fewer biofuels, more green space: Climate action researcher calls for urgent ...

Scientists have harnessed the abilities of both a solar cell and a battery in one device -- a 'solar flow battery' that soaks up sunlight and efficiently stores it as chemical energy for later on-demand use. Their research could make electricity more accessible in remote regions of the world.
Photosynthesis discovery could help next-gen biotechnologies
24 Sep 2018 at 2:44pm
Researchers have purified and visualized the 'Cyclic Electron Flow' (CEF) supercomplex, a critical part of the photosynthetic machinery in all plants, in a discovery that could help guide the development of next-generation solar biotechnologies.
Origami inspires highly efficient solar steam generator
19 Sep 2018 at 8:14am
Water covers most of the globe, yet many regions still suffer from a lack of clean drinking water. If scientists could efficiently and sustainably turn seawater into clean water, a looming global water crisis might be averted. Now, inspired by origami, the Japanese art of paper folding, researchers have devised a solar steam generator that approaches 100 percent efficiency for the production of clean water.
Europe's renewable energy directive poised to harm global forests, experts argue
12 Sep 2018 at 5:12am
Europe's decision to promote the use of wood as a 'renewable fuel' will likely greatly increase Europe's greenhouse gas emissions and cause severe harm to the world's forests, according to a new paper.
Barriers and opportunities in renewable biofuels production
11 Sep 2018 at 8:02am
Researchers have identified two main challenges for renewable biofuel production from cheap sources. First, lowering the cost of developing microbial cell factories, and second, establishing more efficient methods for hydrolysis of biomass to sugars for fermentation.
