IX. Read the passage carefully, then answer the questions: (1m)

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. Experimental work is being done to derive synthetic fuels from coal, oil
shale, and coal tars. But to date, that process has proven expensive. Other experiments are underway to harness
power with giant windmills. Geothermal power 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 currents, tides, and waves to
electricity. Experiments are also underway to make use of temperature differences in ocean water to produce
energy.
