Wind Energy
In windy places, large windmills called wind
turbines can be used to capture the energy of the wind. Often lots
of these turbines are built together on a “wind farm” and used to create
electricity. Smaller turbines can also be used to provide electricity
to individual homes or to small villages. Some wind turbines can also
be used to pump water or grind grain.
Wind turbines are often very tall. This is because wind speed increases
with height - so taller towers allow turbines to capture more wind energy
and generate more electricity. These tall towers can often be seen from
a long distance, so care must be taken when planning where to build
wind farms.
