The development of
economics has been dependent on both the availability
and the advancement of energy. Addition, Today
energy source can affect local,
regional, and global environments through land
use and degradation, air pollution, the acidification
of water and soils, and through global climate
change via greenhouse gas emissions, and
require additional advancement before they can
become cost-competitive with conventional energy
sources. They also face the challenge of providing
sufficient amounts of electricity to be a meaningful
contributor to our growing power needs.
Gravity is the most abundant
potential energy in the earth and could be an
important factor in our energy future. |
