Most of the countries in the world have searched for alternative sources of energy 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 waste.
Experimental work is being done to derive synthetic fuels from coal, oil, shale and coal tars. But today that process has proven expensive. Other experiments 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 five 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 the temperature differences in ocean water to produce energy.
