Crystalline perovskite cells are the key to cutting-edge thin-film solar cells. Although they already achieve very high levels of efficiency in the laboratory, commercial applications are hampered by the fact that the material is still too unstable. Furthermore, there is no reliable industrial production process for perovskites.
In June 1979 President Jimmy Carter made a huge investment by installing 32 solar panels on the White House roof. At the time, the price of photovoltaic cells hovered close to $40/watt. Seven years later Regan took the panels off again, and when President Obama put the White House back on the solar track just a few months ago, the price of solar PV cells had dropped to $0.74/watt.
Route in Tourouvre-au-Perche cost €5m to construct and will be used by about 2,000 motorists a day during two-year test period.
Germany will soon be home to a groundbreaking wind farm that solves a big problem with wind power: What happens when the wind isn’t blowing?
Lightweight, collapsible, and quick to deploy, this little wind generator might be a viable off-grid portable power source in places where solar isn’t appropriate.
The new Ellum Solar is an intuitive smart light, embedded with sensors that illuminate the dark when motion is detected.
FOSCAT-32 is a uniquely designed folding solar catamaran which hassecured for itself the winning trophy in the A’ Vehicle andTransportation Design Award.
A new report released by WWF-Australia says Australia can be powered on 100% renewables with the same levels of reliability that we enjoy today.
In the first study of its kind, scientists have been able to measure the climatic effect of a wind farm on the local environment.
