What
is an Windturbines?
Wind is a form of solar energy. Winds are caused by the uneven heating
of the atmosphere by the sun, the irregularities of the earth's surface,
and rotation of the earth. Wind flow patterns are modified by the earth's
terrain, bodies of water, and vegetation. Humans use this wind flow,
or motion energy, for many purposes: sailing, flying a kite, and even
generating electricity.
The terms wind energy or wind power describe the process by which the
wind is used to generate mechanical power or electricity. Wind turbines
convert the kinetic energy in the wind into mechanical power. This mechanical
power can be used for specific tasks (such as grinding grain or pumping
water) or a generator can convert this mechanical power into electricity.
So how do wind turbines make electricity? Simply stated, a wind turbine
works the opposite of a fan. Instead of using electricity to make wind,
like a fan, wind turbines use wind to make electricity. The wind turns
the blades, which spin a shaft, which connects to a generator and makes
electricity. Take a look inside a wind turbine to see the various parts
