Using an atomic-force microscope fitted with an electrode tip 1,000 times smaller than a human hair, researchers have identified in real time how nanoscale catalysts collect charges that are excited by light in semiconductors. It's a discovery that could help efforts to design devices that can store solar power for later use.
Read morePolluting emissions from Chinese thermal power plants declined significantly between 2014 and 2017, according to new research. The study analyzed data from 2014, when China introduced the ambitious Ultra-Low Emissions (ULE) Standards Policy for renovating coal-fired power stations to limit air pollutant emissions, to 2017.

Read moreA new concept for an aluminium battery has twice the energy density as previous versions, is made of abundant materials, and could lead to reduced production costs and environmental impact. The idea has potential for large scale applications, including storage of solar and wind energy.
Read moreThe 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 moreWhen designed holistically, tidal barrage schemes can provide additional transport links for commuters, become tourism destinations, mitigate wildlife habitat loss, as well as provide opportunities to boost people's health and wellbeing with additional options for cycling and walking, say researchers.
Read moreAn 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 moreAn international team of scientists has figured out how to capture heat and turn it into electricity. The discovery could create more efficient energy generation from heat in things like car exhaust, interplanetary space probes and industrial processes.
Read moreA scientist has discovered a way of using one of the world's most abundant natural resources as a replacement for humanmade chemicals in soaps and thousands of other household products.
Read moreA team of scientists has developed a computational model that uses artificial intelligence to find sites for hydropower dams in order to help reduce greenhouse gas emissions.
