True cost of the planet's energy and transport systems
1 Mar 2021 at 10:38am
The hidden social, environmental and health costs of the world's energy and transport sectors is equal to more than a quarter of the globe's entire economic output, new research reveals.
Low-level jets create winds of change for turbines
23 Feb 2021 at 8:07am
Global wind power capacity has increased more than fivefold over the past decade, leading to larger turbines, but low-level jets are one cause for concern. The effects of these strong, energetic wind flows depend on how high the wind flows are in relation to the turbines. Researchers considered three different scenarios in which the LLJs were above, below, and in the middle of the turbine rotors.
Thermal energy storage with new solution meant to ease grid stress
16 Feb 2021 at 3:59pm
Scientists have developed a simple way to better evaluate the potential of novel materials to store or release heat on demand in your home, office, or other building in a way that more efficiently manages the building's energy use.
Aging offshore wind turbines could stunt growth of renewable energy sector
16 Feb 2021 at 8:49am
A new study highlights the urgent need for the UK's Government and renewable energy industries to give vital attention to decommissioning offshore wind turbines approaching their end of live expectancy by 2025. The research reveals that the UK must decommission approximately 300 and 1600 early-model offshore wind turbines by 2025 and 2030, respectively.
Solar awnings over parking lots help companies and customers
10 Feb 2021 at 2:00pm
Engineers look into the untapped potential of parking lots in a study that investigates the energy-related benefits of developing charging stations powered with solar canopies built into the parking infrastructure of large-scale retailers.
Shining a light on the true value of solar power
9 Feb 2021 at 12:18pm
Utility companies have worried that solar panels drive up electric costs for the people who don't have panels. Renewable energy researchers show the opposite is actually true -- grid-tied solar photovoltaic (PV) owners are actually subsidizing their non-PV neighbors.
Radiative cooling and solar heating from one system, no electricity needed
8 Feb 2021 at 10:44am
A new study describes a new technology that provides both radiative cooling and solar heating, all is one system and without using electricity or fuel. It could help impoverished communities, reduce cooling and heating costs, lower CO2 emissions.
Coal and COVID-19: How the pandemic is accelerating the end of fossil power g...
8 Feb 2021 at 5:54am
COVID-19 has not only caused a temporary drop in global carbon dioxide emissions, it has also reduced the share of power generated by burning coal -- a trend that could in fact outlast the pandemic, according to a new study that looked at COVID-19's impact on the energy system and demand for electricity.
Optical coating can simultaneously reflect and transmit the same wavelength, ...
4 Feb 2021 at 4:25pm
The technology, based on Fano resonance, results in a coating that fully reflects only a very narrow wavelength. The technology could improve the effectiveness of devices that use hybrid thermal-electric power generation as a solar energy option.
New global 'wind atlas' propels sustainable energy
3 Feb 2021 at 5:53pm
Wind energy scientists have released a new global wind atlas - a digital compendium filled with documented extreme wind speeds for all parts of the world - to help engineers select the turbines in any given region and accelerate the development of sustainable energy.
Salt battery design overcomes bump in the road to help electric cars go the e...
1 Feb 2021 at 7:30am
Using salt as a key ingredient, researchers have designed a new type of rechargeable battery that could accelerate the shift to greener, electric transport on our roads.
Carbon: Getting to net zero -- and even net negative -- is surprisingly feasi...
27 Jan 2021 at 9:24am
Reaching zero net emissions of carbon dioxide from energy and industry by 2050 can be accomplished by rebuilding U.S. energy infrastructure to run primarily on renewable energy, at a net cost of about $1 per person per day, according to new research.
Solar hydrogen: Photoanodes made of alpha-SnWO4 promise high efficiencies
26 Jan 2021 at 10:40am
Photoanodes made of metal oxides are considered to be a viable solution for the production of hydrogen with sunlight. Alpha-SnWO4 has optimal electronic properties for photoelectrochemical water splitting with sunlight, but corrodes easily. Protective layers of nickel oxide prevent corrosion, but reduce the photovoltage and limit the efficiency. Now a team has investigated at BESSY II what happens at the interface between the photoanode and the protective layer.
Producing green hydrogen through the exposure of nanomaterials to sunlight

Researchers are paving the way towards the production of green hydrogen.
An anode-free zinc battery that could someday store renewable energy
20 Jan 2021 at 5:50am
Renewable energy sources, such as wind and solar power, could help decrease the world's reliance on fossil fuels. But first, power companies need a safe, cost-effective way to store the energy for later use. Massive lithium-ion batteries can do the job, but they suffer from safety issues and limited lithium availability. Now, researchers have made a prototype of an anode-free, zinc-based battery that uses low-cost, naturally abundant materials.
