There are several reasons for the US to develop alternative
energy sources.
1) Fossil fuels are running out. Strong winds, sunny skies,
plant residues, heat from the earth, and fast-moving water can
provide a constant supply of energy.
2) Alternative energy sources such as wind, solar, geothermal,
hydroelectric and biomass produce little or no global warming
emissions.
3) Extraction and transport of fossil fuels causes environmental
damage.
4) Combustion of fossil fuels causes global warming, acid rain
and air pollution and contributes to lung cancer, heart attacks,
neurological damage, and other respiratory illnesses.
5) The renewable energy industry is more labor intensive,
creating more jobs and other economic benefits.
6) Renewable energy prices are relatively stable while fossil
fuel prices can vary and are prone to price swings.
7) There is less risk of large scale failure with wind and solar
energy because they are distributed and modular. A severe weather
event in one area will not cut off power to an entire region.
8) The US will be energy self-reliant, no longer dependent on
other countries and their changing governments and policies.
