World’s average overall energy efficiency ranges from between 30 to
40%. The actual energy efficiency varies from country to country. Since
there are enormous economic and environmental benefits
from improving the World energy efficiency to 70 %, every country
should determine the best way to make the improvements
Programs could improve building's designs, electronic controls, and
heating and cooling systems, which would increase residential,
commercial, and industrial energy efficiencies from 30 to 70%.
Conservation Programs could improve electric power and
transportation to 70% by converting from carbon to clean energy that
would also reduce carbon dioxide emissions.
Achieving a World goal of 70% energy efficiency will significantly
reduced the demand for energy but also save
trillions of dollars and could impact
the World Energy Markets. The U.S.
Energy Information Administration forecast that coal,
liquids, and natural gas would double might actually see the prices of
fossil fuels drop.
