Wind power is a renewable source of energy that is currently increasing in use by 28% every year. If the current growth rate persists, wind power will account for 10% of global electricity production in 2015. In 2007, Swedish wind energy constituted about 1.5% of total electricity production.
Vertical Wind goes against the grain
TThe innovative detail of Vertical Wind turbines is that their technology is based on a vertical axis of rotation so that it captures the wind regardless of its direction. Unlike large horizontal axis wind turbines, the vertical turbine does not need to be facing into the wind to operate. Vertical Wind can also absorb energy from the turbulent winds that cannot be harnessed by traditional wind turbines.
This innovative concept provides a high level of wind production with only a few moving parts. The turbine does not need a gear box (transmission) and the construction is simple, robust and silent. Furthermore, it only requires low maintenance costs.
