Abstract

Worlds electricity demand is increasing at a rapid rate Presently newlinemost of our electricity demand is met by fossil fuels oil coal and natural gas newlineFossil fuels are conventional resources and are not renewable which means newlinethat they will not be replaced within the timespan of human necessity These newlinefossil fuels introduce many harmful pollutants into atmosphere and burning of newlinecontributes to environmental problems like global warming and acid rain newlineBesides growing scarcity and rising prices of these fossil fuels may lead to newlineeconomic instability in the future There are also nonconventional sources of newlineenergy which are renewable they are solar wind biomass geothermal etc newlineRenewable energies are nonpolluting Nowadays renewable energy sources newlineplay an important role in electricity newline
