Energy Information Administration FAQs:

"Different fuels emit different amounts of carbon dioxide (CO₂) in relation to the energy they produce when burned. To analyze emissions across fuels, compare the amount of CO₂ emitted per unit of energy output or heat content.

Pounds of CO₂ emitted per million British thermal units (Btu) of energy for various fuels:

The U.S. Geological Survey (USGS) estimates that the United States has the geologic formations to store approximately 3,000 metric gigatons of carbon dioxide.¹ For comparison, the United States produces around 5.3 gigatons of carbon dioxide per year.² Humans worldwide currently produce around 34 metric gigatons of carbon dioxide per year.³
