The land-based wind energy resource in the United States is over 10,000,000 megawatts, which could produce enough electricity to power the entire country 10 times over.

The wind provides another free and inexhaustible source of clean energy. Wind turbines harness the kinetic energy of moving air and convert it into electricity without releasing harmful air emissions or consuming water.

Sempra U.S. Gas & Power is an equal partner in five operating wind farms that are collectively capable of generating more than 1,000 MW of clean energy for roughly 325,000 homes. In partnership with BP Wind, our company recently completed two projects in Kansas and Pennsylvania that are currently the largest ever built in their respective states. Additionally, Sempra U.S. Gas & Power recently completed an innovative wind project in Maui, Hawaii.

How A Wind Turbine Works

When the wind turns the blades of a wind turbine, it rotates the shaft inside the turbine's generator and produces electricity. The electricity travels through transmission lines to a substation, then on to homes, businesses and schools through local distribution lines.

The bigger the wind turbine, the more electricity it produces. Turbines are generally built in remote areas with more active wind conditions.
