Read the text carefully then choose the correct answer: The search for alternative source of energy has led in various directions. Many opportunities are burning garbage and other biological products to produce electricity. Converting waste products to gases or oil is also an effective way to dispose of waste. Experimental work is being done to desire synthetic fuels from coal, oil shale and oil tars. But today, that process has proven expensive. Other experiments are underway to harness power with windmills. Some experts expect utility companies to revive hydroelectric power derived from steams and rivers. Fifty years ago hydroelectric power provided one third of the electricity used in the United States, but today it supplies only four percent. The oceans are other potential source of energy. Scientists are studying ways to convert the energy of ocean currents, tides and ways to electricity. Experiments are also underway to make use of temperature differences in ocean water to produce energy. 46. Which is the best title for the passage? a. The use of water products for energy. b.
