We need to do something before we run out of man made sources for energy.
Renewable energy technologies produce sustainable, clean energy from
sources such as the sun, the wind, plants, and water. According to the
Energy Information Administration, in 2007, renewable sources of energy
accounted for about 7% of total energy consumption and 9.4% of total
electricity generation in the United States. Renewable energy
technologies have the potential to strengthen our nation's energy
security, improve environmental quality, and contribute to a strong
energy economy....(more)
The United States currently relies heavily on coal, oil, and natural
gas for its energy.
Fossil fuels are non-renewable, that is, they draw on finite resources
that will eventually dwindle, becoming
too expensive or too environmentally damaging to retrieve. In
contrast, the many types of renewable energy resources-such as wind and
solar
energy-are constantly replenished and will never run out.
Most renewable energy comes either directly or indirectly from the sun.
Sunlight, or solar energy,
can be used directly for heating and lighting homes and other buildings, for generating electricity,
and for hot water heating, solar cooling, and a variety of commercial and industrial uses..(more)
