Fossil fuels provide most of the energy that powers U.S. industry.
Fossil fuels are consumed at an increasing rate, and they are not renewable within human life spans. Hydroelectric power has been an extensively developed alternative. Recently, there has been increasing public resistance to development of more hydroelectric and nuclear power sites. Other alternatives such as hydrogen, sun, and wind do not have widespread acceptance, due to high costs. Since our everyday lives are so dependent on fuels as energy sources, conservation programs have been adopted to insure efficient production and use.
