D. They donft. Turbines depend on weather forecasts Collapse and uncheck the INTRODUCTION folder.

GLOBAL PERSPECTIVE

Wind power is a form of solar power. Solar radiation (sunlight) heats up the surface of the Earth, but does so unevenly. This is because surfaces on Earth absorb, retain, and release heat at different rates. The uneven heating of the Earthfs surface results in the formation of unequal pressures in the atmosphere; namely, high pressures and low pressures. As air pressure moves from high pressure areas to low pressure areas, wind forms. We can harness the power of wind near the Earthfs surface with wind turbines, and convert the kinetic energy of wind into electricity (measured by kilowatts, kW, or megawatts, MW) for our homes and businesses. Note that all the wind speeds have been rounded to the nearest mile per hour. Remember to include your unit of miles per hour. Expand the GLOBAL PERSPECTIVE folder.
