This reaction gives Direct Current electricity though, and it must be passed through an inverter to be converted into an Alternating Current used in our homes to power any electrical items. Some of the power is lost in this part of the process as the inverter is only around 95% efficient but this is a much greater efficiency than was once available.

Save Energy: September 2007
To expand on that simplification, the turbine’s blades are connected to a hub that’s mounted atop a turning shaft which runs into a gear transmission box that increases the turning speed which, in turn, is connected to a high speed shaft that cranks the generator. If the wind speeds get too high, a brake is deployed to slow the blades down and prevent damage being done to the system. 2-blade horizontal axis turbines spin downwind. 3-blade horizontal axis turbines spin upwind vertical axis wind turbines.
