Energy is defined in Webster's dictionary as "capacity for action or performing working." Any action that occurs in nature are accompanied by a reduction in the overall quality of energy while energy is neither destroyed not created, but transformed into state or form with an overall lower quality or potential. (Matter may be considered as a special forms of energy and should also to be included in the energy conservation principle stated above when involving nuclear energy.) Higher forms of energy are been harnessed by natural or humen processes and are downgraded to lower forms of energy and rendered often useless, thus a continuous depletion of usefull energy forms occur in nature. The various forms of energy including heat, light, microwaves, electricity, potential energy stored in a body held in a force field, say the gravitational field at an elevation, kinetik energy of a moving object, energy associated with the chemical bonds that hold atoms and molecules together and nuclear energy that created by transforming matter into energy. Primary sources of energy are being fossil fuels such as natural gas, oil, coal and to a lesser extent, nuclear by fission of radioactivity elements (in France however, majority of electricity is producing by nuclear), solar in direct heating, in photovolcanic cells, rivers that provide hydroelectricity which in certain regions such as the U. S. Pacific Northwest and in Norway and Sweden is vary significant (note that it is the solar energy that was actually "drives" the rivers), wind for turning turbines to generate electricity, geothermal, biomass and possibly oil shale in the future.
