11. Read the passage and circle the best option A, B, or C. (1.5 points)
Since pollution and CO2 emissions have become a problem in our world, scientists have turned
to new forms of catching energy. They have used water power from rivers and tides, light and heat
from the sun, as well as wind power from the wind. The wind is blowing around us all the time.
There's a lot of energy there, and scientists have figured out how to use it.
Wind turbines take wind energy and make it into electricity that humans can use. A wind
turbine usually has three or four arms that are designed to catch the wind. When they do, these four
arms turn in a circle. The turbine is connected to a generator, which works to change the wind
energy into electricity. Wind turbines have been built all over the world.
A wind farm is a place where many wind turbines are built. The biggest wind farm in the world
is in Roscoe, Texas. It has 627 wind turbines. Wind farms are often built off the coast because areas
over the ocean have strong winds. The Thanet Wind Farm in the United Kingdom is the biggest
offshore wind farm. Many believe that wind turbines and wind farms will be important for the
future, as we need cleaner energy.
