This website also provides climate change news, green products and information on alternative energy including solar power as well as wind power.
Makani Power is developing a new type of wind turbine, capable of reaching the stronger and more consistent winds above the reach of conventional wind systems. Wing 7 is a 20 kW rated Airborne Wind Turbine (AWT) with a wingspan of eight meters and a mass of 58.4 kg. Wing 7 has been developed with the support of the Department of Energy, office of ARPA-E, and Google. In this September 1, 2011 flight, the AWT can be seen autonomously transitioning from hover into crosswind flight, flying crosswind to generate power and transitioning out of crosswind back into hover. Following this flight, Makani demonstrated launching and landing from a perch to hover, validating all of the flight modes needed for complete autonomous operation.
Wind power… it’s sustainable … it burns no fossil fuels…it produces no air pollution. What’s more, it cuts down dependency on foreign oil. That’s what the people of Meredith, NY first thought when a wind developer looked to supplement the rural farm town’s failing economy with a farm of their own — that of 40 industrial wind turbines. But when a group of townspeople discover the impacts that a 400-foot high windmill could bring to their community, Meredith’s residents become deeply divided as they fight over the future of their community. With wind development in the United States growing annually at 39 percent, Windfall is an eye-opener for anyone concerned about the environment and the future of renewable energy.
In the past three years, China has emerged as a world leader in the development of renewable energy as a part of its growing efforts to combat climate change and create new jobs in clean technologies. ClimateWorks traveled to China to get a sense of the scale of wind power development and talk to some local experts about China’s goals for reducing pollution and growing its renewable energy industry.
