Key US Energy Sources for Power Generation

In order of importance the US uses coal, natural gas, nuclear, water power, geothermal, biomass, wind and solar.

Key US Energy Source for Transportation

Oil powers most of the vehicles in the US. However, these can also run on alcohols such as methanol and ethanol made from natural gas.

The US oil supply peaked in 1971, i.e., we have never since drawn as much oil out of US soil. The rate of decrease is such that, even with the Alaska oil finds, and shale oil production, we are pumping less than half the 1971 amount per day.

Domestic Energy Resources

Discussion of the relative role of our energy sources is adequately presented in myriad DOE web sites, and the reader is referred to them (see for example What IER wants to concentrate on and spur discussion of is the only fossil fuel that has a renewable counterpart, natural gas. This fuel, while burning much cleaner than coal, or gasoline, is domestically supplied (whether fossil or renewable), in abundant supply as fossil fuel, and by making a national effort to make use of our wastes to generate the renewable version, we can add a major amount to our energy supply while significantly reducing our waste problems, and definitely lowering the CO2 addition we make to the atmosphere. Although it can be used in Internal Combustion Engines directly, by compressing it or liquefying it, it is better utilized by converting it to methanol, which allows a much larger fraction of our existing infrastructure to remain the same, while still getting the benefits of using our natural gas.

Fossil Natural Gas

As recently as 2009, the 'official' view has been that the US is running out of fossil natural gas. However, as insiders new, new technology has enabled vast reserves of formerly unobtainable natural gas to be acquired. The Potential Gas Committee, an organization of geologists long relied upon to make reliable estimates, has this summer 2009, determined that we have 80-100 years of natural gas if we take into account the newly available finds of shale gas. This map give some idea of the vastness of the shale gas reserves in 2005, and the growth in those reserves in 2011 here.

Renewable Natural Gas

Renewable natural gas has two main sources, the portion coming from wastes, municipal, industrial and farm, and a component coming from the anaerobic digestion of cultivated bio-mass. Renewable natural gas will constitute a major component of our energy needs, with essentially a zero carbon footprint. Although the methane burning will release CO2, the methane prevented from entering the atmosphere if the wastes were allowed to decay under controlled conditions and the gases captured, more than compensates for the CO2 from combustion. Furthermore, additional CO2 is taken from the atmosphere by growing the bio-mass. Go to link on Renewable natural gas.
