What is the Full Fuel Cycle?
Many people feel energy efficiency begins and ends in their homes. In reality, energy efficiency begins prior to reaching your home. The Full Fuel Cycle represents the amount of energy expended to bring a fossil fuel, such as coal from the earth to your home.
What is CO2
Carbon dioxide (CO2) is a colorless, odorless, non-combustible greenhouse-gas that contributes to global warming. It is formed by complete combustion of fossil fuels (coal, charcoal, natural gas, petroleum) and carbon containing products (such as wood). It also is released through respiration by living organisms and by the gradual oxidation of organic matter in soil.
What is global warming?
It is the increase in the average temperature of the earth's near-surface air and oceans since the mid-20th century and its projected continuation. Most global warming is due to the increase of man-made greenhouse gases.
How were the CO2 emissions calculated on your Web site?
Electric emissions were obtained from the EIA eGRID 2006 report. The emission data for natural gas was obtained from the EPA Clean Energy Calculations and References as 117 lbs. CO2/decatherm.
