Paper from Land Use History of North America giving results of a study to estimate the extent of developed land in the United States and the impact of development on soil resources.
We estimated in-place resources of 1.07 trillion short tons of coal in this area using a geology-based assessment methodology. Of that total, recoverable coal was 162 billion tons, 25 billion economically recoverable.
We estimate that there are about 85 trillion cubic feet (TCF) of undiscovered, technically recoverable gas resources within gas hydrates in northern Alaska.
Using the Fischer assay measure of oil yield, we estimated a total of 1.44 trillion barrels of oil in three assessed units. There is currently no economic method to recover oil from this geologic unit.
We estimated a total of 1.525 trillion barrels of oil are in place in seventeen oil shale zones in this area using a geology-based assessment methodology.
Using a geology-based assessment methodology, we estimated a total of 1.32 trillion barrels of oil in place in eighteen oil shale zones in this Eocene geologic unit.
The electric power generation potential from identified geothermal systems is 9,057 Megawattselectric (MWe), distributed over 13 states. Undiscovered resources are estimated to provide an additional 30,033 MWe.
