INCIPIENT TRENDS IN ENERGY FORAGING: A REVIEW

Abstract

The search for new alternative energy systems has increased greatly in the last few decades for the following reasons: The extra demand on energy within the next five decades will continue to increase in such a manner that the use of fossil fuels will not be sufficient, and therefore, the deficit in the energy supply will be covered by additional energy production and discoveries. Fossil fuels are not available in every country because they are unevenly distributed over the world,
but renewable energies are more evenly distributed and, consequently, each country will do its best to research and develop their own national energy
harvest. Fossil fuel combustion leads to some undesirable effects such as  atmospheric pollution because of the CO2 emissions and environmental
problems including air pollution, acid rain, greenhouse effect, climate changes, oil spills, etc. It is understood by now that even with refined precautions and technology, these undesirable effects can never be avoided completely but can be minimized. One way of such minimization is to substitute at least a
significant part of the fossil fuel usage by renewable energy sources
