Small Wind Electric Systems | Department of Energy
How a Small Wind Electric System Works. Wind is created by the unequal heating of Earth''s surface by the sun. Wind turbines convert the kinetic energy in wind into clean electricity. When the wind spins the wind turbine''s blades, a rotor captures the kinetic energy of the wind and converts it into rotary motion to drive the generator.
Section B: Off-grid and Grid-intertied Systems
A renewable energy system that generates electricity can either be tied into the grid (grid-intertied system), or it can operate separately from the grid (off-grid). Off-grid renewable energy systems are not connected to the utility electrical grid. These systems have no wires bringing electricity on or taking electricity from the site.
