Renewable Energy
Efficiency measures can help conserve on both the supply and
demand sides of energy use. Using renewable energy technologies
makes a difference at the source.
While the supplies of fossil fuel-based energy sources such as
coal, oil or natural gas are finite, sources like wind and biomass
are constantly replenished or renewed. So no matter how much is
used today, there will still be the same supply in the future.
There are additional advantages for the use of renewables. These
include:
- Many countries do not have domestic supplies of coal or oil
and must import much of their energy, but most countries do
have access to some form of renewable energy which can be
readily tapped.
- As a source of clean, non-polluting electricity
they emit no air pollution or greenhouse gases and thereby
have excellent appeal for greenhouse reduction/stabilization
strategies.
- For several countries that rely on imported
fuels for power generation, there could be some significant
savings by developing sustainable energy policies. Conservation
and renewables also help a country's fuel supply diversity
and security.
- They can help transform rural economies into
more viable communities for national development in most
developing countries, by providing power for small-scale
industries and job creation.
Most renewable energy comes either directly or indirectly from
the sun. Current renewable energy sources include: hydropower,
biomass, wind, solar, and geothermal. Power from these energy
sources is already being used successfully around the world.
