As in a past decades, the world today continues to be at crossroads in terms of energy.
Shortages and rising prices of fuel, accompanied by environmental damage are
leading to a poor quality of life. Fossil fuel consumption is increasing, and our search
for oil has led to ever deeper reserves, with its higher production costs. Rapid
depletion of oil and gas are real issues affecting both current and future generations.
Hydraulic fracturing is an industrial process used to extract fossil fuel reserves that
lie deep underground. With the introduction of horizontal drilling, new commercial sources
of energy have become available. Wells are drilled and injected with large quantities of water
mixed with specially selected chemicals at high pressures that allow petroleum reserves to
flow to the surface. While the increased economic activities and the outputs of domestic energy
are welcomed, there is growing concern over negative environmental impacts from horizontal
drilling in shale formations.
The amount of energy that
people used in the past two decades is equivalent to the total amount of energy in
the past. This huge increase of energy use has been made possible by extending
depletion of fossil reserves and is clearly unsustainable. Does it mean that once the
reserves are exhausted the amount of energy available to humans would be similar
before the era of fossil fuels? Not necessarily. Currently, the total energy used by mankind
No. 1/5500 fraction of the total incident solar energy on earth....
Welcome to this 31st edition of the Transportation Energy Data Book. This edition builds
on a 36-year tradition of Data Books supported by Philip Patterson, whose recent retirement
marked the end of an era for a long-time asset and shining example both for the Department of
Energy (DOE) and the transportation energy community. Twenty-two editions of this Data Book
have been produced by Stacy Davis; DOE is grateful for the dedication, consistency, and skill
she has brought to this effort....
