IV. Read the following passage and choose the best answer.
The search for alternative sources of energy has led in various directions. Many communities are
burning garbage and other biological waste products to produce electricity. Converting waste products to
gases or oil is also an efficient way to dispose of wastes. Experiment work is being done to derive
synthetic fuels from coal, oil shale, and coal tars. But to date, that process has proven expensive. Other
experimental are underway to harness power with giant windmills. Geothermal power, heat from the
earth, is also being tested. Some experts expect utility companies to revive hydroelectric power derived
from streams and rivers. Fifty years ago hydroelectric power provided one third of the electricity used in
the United States, but today it supplies only 4 percent. The oceans are another potential source of energy.
Scientists are studying ways to convert the energy of ocean, tides, and waves to electricity. Experiments
are also underway to make use of temperature differences in ocean water to produce energy.
