The economic case for wind, solar energy in Africa
27 Mar 2017 at 2:28pm
To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment has found that wind and solar can be economically and environmentally competitive options and can contribute significantly to the rising demand.

24 Mar 2017 at 5:30am
Renewable thermal technologies have significant market potential in the state if supported by appropriate public policy and financing tools, a new analysis concludes.
New study calls for US solar policy reform
23 Mar 2017 at 12:02pm
Researchers suggest reforming US solar policies and encourage closer collaboration between the United States and China on solar energy in a new report.
Revealing the microscopic mechanisms in perovskite solar cells
21 Mar 2017 at 9:40am
In just a few years, researchers have achieved remarkable power conversion efficiency with materials with perovskite crystal structure, comparable with the best photovoltaic materials available. Now, researchers have revealed the physics for how an important component of a perovskite solar cell works -- a finding that could lead to improved solar cells or even newer and better materials.
Liquid storage of solar energy: More effective than ever before
20 Mar 2017 at 5:54am
Researchers have demonstrated efficient solar energy storage in a chemical liquid. The stored energy can be transported and then released as heat whenever needed, they say.
Nanotube film may resolve longevity problem of challenger solar cells
17 Mar 2017 at 7:23am
Researchers have lengthened the lifetime of perovskite solar cells by using nanotube film to replace the gold used as the back contact and the organic material in the hole conductor.
Hydrogen on demand
13 Mar 2017 at 4:27pm
Using solar energy, researchers have developed a new method for safely and efficiently producing hydrogen in a centralized manner, miles away from the solar farm. It could greatly reduce the cost of producing hydrogen and shipping it to customers.
Scientists harness solar power to produce clean hydrogen from biomass
13 Mar 2017 at 10:49am
A team of scientists has developed a way of using solar power to generate a fuel that is both sustainable and relatively cheap to produce. It's using natural light to generate hydrogen from biomass.
Switzerland could generate more energy out of used wood
13 Mar 2017 at 7:29am
Switzerland is not fully exploiting a significant source of clean energy: 173,000 tonnes of used wood could be re-used producing valuable heat and power energy today, in addition to the 644,000 tonnes of used wood already being used. This was the conclusion reached by a nationwide survey among 567 companies in the construction, waste management and transport sectors.
Environmentally friendly, almost electricity-free solar cooling
13 Mar 2017 at 5:56am
Demand and the need for cooling are growing as the effects of climate change intensify. An emission-free, solar-powered chiller has now been developed by scientists. The potential market is world-wide, particularly in warm countries.
Chemists create molecular 'leaf' that collects and stores solar power without...
8 Mar 2017 at 10:53am
An international research team has engineered a molecule that uses light or electricity to convert the greenhouse gas carbon dioxide into carbon monoxide -- a carbon-neutral fuel source -- more efficiently than any other method of "carbon reduction." The discovery is a new milestone in the quest to recycle carbon dioxide in the Earth's atmosphere into carbon-neutral fuels and others materials.
