Wind Power
-
Extreme engineering is becoming the norm as offshore wind continues to scale up. Sweeping the area of 12.3 standard NFL fields each rotation, with gargantuan 140-meter (459-ft) blades, the MySE 18.X-28X will be the largest wind turbine ever built.
-
Wind energy is often thought of as "clean" but, in fact, the technology has the blood of thousands (if not millions) of bats on its hands. A new drone-mounted system shows promise in rerouting some bats above the turbine blades and away from danger.
-
Floating wind turbines are crucial to the future of offshore wind, but they require radically different thinking. French company Eolink is building a full-scale pyramid-style floating wind turbine that reduces materials and weight by more than 30%.
-
Aeromine says its unique "motionless" rooftop wind generators deliver up to 50% more energy than a solar array of the same price, while taking up just 10% of the roof space and operating more or less silently. In independent tests, they seem legit.
-
While wind energy systems can come in some pretty big forms, scientists at Nanyang Technological University (NTU), Singapore have developed a small, low-cost device sensitive enough to capture energy from a light breeze.
-
A prototype wind turbine has recorded an extraordinary single-day renewable energy production total, bringing in a massive 359 megawatt-hours in a 24-hour time period. To get there, it had to operate over its rated capacity, essentially all day long.

As the shipping industry moves to decarbonize, huge sails could be making a comeback. The China Merchant Energy Shipping company (CMES) has taken delivery of a new supertanker, whose four large sails will cut down average fuel consumption by nearly 10%.
-
Swedish company SeaTwirl says its floating vertical-axis wind turbines have what it takes to dramatically reduce the cost of deep offshore wind energy, and it's signed a deal with Westcon to build and deploy a commercial-scale 1-MW turbine in Norway.
-
We interviewed the core team at Norway's World Wide Wind to learn more about its floating, tilting, contra-rotating, double turbine design, which it says can unlock unprecedented scale, power and density to radically lower the cost of offshore wind.
-
Norway's World Wide Wind has a radically different take on offshore wind power. These floating, vertical-axis wind turbines feature two sets of blades, tuned to contra-rotate – and they promise more than double the output of today's biggest turbines.
-
Through its massive wind turbines and innovative offshore designs, GE continues sharpening its toolkit in a bid to built the future of sustainable energy, and a newly unveiled turbine blade shows how that can extend to the materials used.
-
New renewable energy projects in the Gobi and other deserts will raise China's world-leading wind and solar capacity by a further 70 percent. Some 450 GW of new capacity will cement China as both the biggest and fastest-growing renewable energy generator.
