DESCRIPTION

Facts  USA constitutes 4.5% of the world population, yet we consume 25% of planets energy resources and emit 25% of the global greenhouse gas emissions.  In order to stabilize the concentration of carbon dioxide in the atmosphere at 550 ppm (double the pre-industrial amount) within the next 100 years would require cutbacks of ~70% from current levels.  For USA in 2001, renewable energy generated was 5.5 quadrillion(10 15 ) BTU of the total 97.3 quadrillion BTU of energy consumed or about 5.7%.

consume 25% of planets energy resources and emit consume 25% of planets energy resources and emit 25% of the global greenhouse gas emissions. 25% of the global greenhouse gas emissions.

In order to stabilize the concentration of carbon dioxide In order to stabilize the concentration of carbon dioxide in the atmosphere at 550 ppm (double the pre-industrial in the atmosphere at 550 ppm (double the pre-industrial amount) within the next 100 years would require amount) within the next 100 years would require cutbacks of ~70% from current levels.cutbacks of ~70% from current levels.

For USA in 2001, renewable energy generated was 5.5 For USA in 2001, renewable energy generated was 5.5 quadrillion(10quadrillion(101515) BTU of the total 97.3 quadrillion BTU of ) BTU of the total 97.3 quadrillion BTU of energy consumed or about 5.7%.energy consumed or about 5.7%.

Older coal plants (~1940’s) escape the 1990 Clean Air Act through a congress Older coal plants (~1940’s) escape the 1990 Clean Air Act through a congress approved “grandfather” clause. It is estimated by Environmentalists to be about approved “grandfather” clause. It is estimated by Environmentalists to be about a 2¢/kWh subsidy. This is due to their lack of incorporating cleaner processes a 2¢/kWh subsidy. This is due to their lack of incorporating cleaner processes to reduce NO/NOto reduce NO/NO22 & SO & SO22 emissions. emissions.
