Researchers worldwide are working on a concept for high-altitude wind power: automated light aircraft flying 300-500 meters high, connected by cable to an electricity generator. Each movement of the aircraft is converted to electrical power.
More than 100 cities worldwide get at least 70 percent of their electricity from renewable sources, according to a new initiative. How did they manage and what can we learn from them?
Ireland's wind power potential is vast, and although wind now supplies more than a fifth of the country's electricity, the potential remains mostly untapped. Siemens Gamesa is striving to change that.
The UK is the current world leader in offshore wind capacity. But with the country heading for the EU exit door, can the renewable energy boom last?
France has launched its first offshore turbine to curb reliance on nuclear and reach climate goals — France could become Europe's second-largest wind energy producer after Germany. But the transition brings problems.
