Alternative Energy Sources

Alternative Energy Sources

Introduction

The depletion of conventional and non-renewable sources of energy i .e fossil fuels , which include coal , gasoline and natural gas , has caused concern among the policy makers and the consumers . Moreover , the recent increase in oil prices has caused inflation due to higher transportation costs of the commodities . However , the biggest drawback of using the non-renewable sources of energy has been an increase in environmental pollution , and the phenomenon of global warming . When the fossil fuels are burnt by millions of vehicles on road , ships on water

, and by aeroplanes in air , toxic emissions including deadly hydrocarbons , and lethal carbon monoxide are released into the atmosphere . These poisonous gases cause severe respiratory diseases , and cancer in the most vulnerable human population i .e . children and elderly . Is it beneficial to continue the use of fossil fuels whose emissions cause deadly diseases in humans ? Also , one of the emissions is carbon dioxide , which is the main cause of global warming . Since the fossil fuels are limited in supply , scientists , environmentalists and policy makers have been striving to find the alternative sources of energy , which are replenishable , easily available , non-polluting , non-detrimental to the health of humans , environmental friendly and do not cause global warming . Isn 't it beneficial for us to explore and deploy the alternative energy sources ? I strongly feel that we must develop technology to commercially exploit the alternative energy sources . Some of the types of alternative energy sources along with their utility to humanity are...
