he 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 [arrange] of wastes. Experiment work is being done to
derive [gain] synthetic [combining] fuels from coal, oil shale, and coal tars [nhựa]. But to date, that process
has proven expensive. Other experimental are underway to harness [tận dụng] 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.
