Putting alternative sources of energy into prospective

The present United States energy consumption pattern is discussed and a realistic evaluation of the various energy options for the next ten to thirty years is presented. In this period oil and natural gas will essentially be exhausted and the emphasis will most likely shift to coal, nuclear energy, solar energy and synthetic fuels. Other alternative energy sources should also be developed since they may offer excellent solutions to specific regions. Energy conservation is essential and must be continuously implemented in all sectors of the economy.
