“Vertical axis wind turbines are advocated as being capable of catching the wind from all directions, and do not need yaw mechanism, rudders or downloading coning. Their electrical generators can be positioned close to the ground, and hence easily accessible.”
“However, small vertical axis wind turbines are more suited to urban areas as they have a low noise level and because of the reduced risk associated with their slower rates of rotation
One can foresee some future where each human dwelling in the world is equipped with wind generators and solar collectors, making them indispensible for human well being.”
“Wind Energy Outlook 2015: Total Installed Wind Capacity could Reach 2,000 GW by 2030”
In the face of a four-year wind growth stagnation and an energy market that has seen oil fall to its lowest price in years, with robust policy to address climate change, wind power could supply close to 20 percent of global electricity demand by 2050.
Under an advanced policy scenario — the manifestation of the iron political will required in order addressing climate change — wind power could reach a total installed global capacity of 2,000 GW by 2030, supplying up to 19 percent of global electricity. This is the key conclusion of the latest Global Wind Energy Outlook (GWEO) from the Global Wind Energy Council (GWEC) and Greenpeace.
