Conventional and non-conventional sources of energy

   Conventional energy sources are typically fully developed, nonrenewable resources, while nonconventional sources may be functional but are still undergoing development and use renewable resources. Conventional sources of energy usually include fossil fuels like coal, natural gas and oil as well as nuclear power. Nonconventional sources include solar power, hydropower and wind power. Fossil fuels are inexpensive and require established technologies that can produce energy around the clock. Nonconventional energy sources have a much smaller environmental footprint and are renewable. Conventional sources of energy have a limited supply because eventually the nuclear elements and fossil fuels will be used up. In addition, burning fossil fuels release significant amounts of greenhouse gases and contribute to acid rain. Nonconventional energy sources are quite expensive and are often limited to producing energy only under certain circumstances such as sunny days for solar plans and windy days for windmills. Fossil fuels provide about 85 percent of the energy in the United States, and oil provides almost all of the energy for automobiles. Even though there are significant environmental costs associated with fossil fuels, the U.S. Department of Energy expects their usage to increase of the next 20 years because nonconventional energy sources will not develop quickly enough to meet the growing energy demands. Many sources of power are also base upon a thermal cycle including solar power towers and parabolic trough collectors, coal, oil, gas, nuclear. Some power that is not thermal base includes hydroelectric, wind, and photovoltaic.
