ENVIRONMENT AND ENERGY <br />The single most important human component in the preservation <br />of the Earth's environment is energy. Industrial conversion of energy <br />into forms that are useful for human activities is the most important <br />aspect of technology. Abundant inexpensive energy is required for <br />the prosperous maintenance of human life and the continued advance <br />of life-enriching technology. People who are prosperous have the <br />wealth required to protect and enhance their natural environment. <br />Currently, the United States is a net importer of energy as shown <br />in Figure 25. Americans spend about $300 billion per year for im- <br />ported oil and gas - and an additional amount for military expenses <br />related to those imports. <br />s.sx I.preH <br />N~ral Gtr <br />/ ~ <br />~ ux x~elar <br />-\ ss% HyanaNetric <br />aN OH~r <br />\ x.37% Wl.i ui 3dar <br />zs.7x I.prta oe ~ ss% D..e.tle ou <br />Isporbd Ee~rp- <br />s3e~ sili~o^ w^^^a1 co.t <br />Figure 25: In 2006, the United States obtained 84.9% of its energy from hy- <br />drocarbons, 8.2% from nuclear fuels, 2.9% from hydroelectric dams, 2.1% <br />from wood, 0.8% from biofuels, 0.4% from waste, 0.3% from geothermal, <br />and 0.3% from wind and solar radiation. The U.S. uses 21 million barrels of <br />oil per day - 27% from OPEC, 17% from Canada and Mexico, 16% from <br />others, and 40% produced in the U.S. (95). The cost of imported oil and gas <br />at $60 per barrel and $7 per 1,000 ft in 2007 is about $300 billion per year. <br />Political calls for a reduction of U.S. hydrocarbon use by 90% <br />(123), thereby eliminating 75% of America's energy supply, are ob- <br />viously impractical. Nor can this 75% of U.S. energy be replaced by <br />alternative "green" sources. Despite enormous tax subsidies over the <br />past 30 years, green sources still provide only 0.3% of U.S. energy. <br />Yet, the U.S. clearly cannot continue to be a large net importer of <br />energy without losing its economic and industrial strength and its po- <br />litical independence. It should, instead, be a net exporter of energy. <br />There are three realistic technological paths to American energy <br />independence -increased use of hydrocarbon energy, nuclear en- <br />ergy, or both. There are no climatological impediments to increased <br />use of hydrocarbons, although local environmental effects can and <br />must be accommodated. Nuclear energy is, in fact, less expensive <br />and more environmentally benign than hydrocarbon energy, but it <br />too has been the victim of the politics of fear and claimed disadvan- <br />tages and dangers that are actually negligible. <br />For example, the "problem" of high-level "nuclear waste" has <br />been given much attention, but this problem has been politically cre- <br />ated by U.S. government barriers to American fuel breeding and re- <br />processing. Spent nuclear fuel can be recycled into new nuclear fuel. <br />It need not be stored in expensive repositories. <br />Reactor accidents are also much publicized, but there has never <br />been even one human death associated with an American nuclear re- <br />actor incident. By contrast, American dependence on automobiles re- <br />sults in more than 40,000 human deaths per year. <br />All forms of energy generation, including "green" methods, entail <br />industrial deaths in the mining, manufacture, and transport of re- <br />sources they require. Nuclear energy requires the smallest amount of <br />such resources (124) and therefore has the lowest risk of deaths. <br />Estimated relative costs of electrical energy production vary with <br /> <br />~ is.sx coi <br />geographical location and underlying assumptions. Figure 26 shows <br />a recent British study, which is typical. At present, 43% of U.S. en- <br />ergy consumption is used for electricity production. <br />To be sure, future inventions in energy technology may alter the <br />relative economics of nucleaz, hydrocarbon, solar, wind, and other <br />methods of energy generation. These inventions cannot, however, be <br />forced by political fiat, nor can they be wished into existence. Alter- <br />natively, "conservation," if practiced so extensively as to be an alter- <br />native to hydrocarbon and nuclear power, is merely a politically <br />correct word for "poverty." <br />The current untenable situation in which the United States is los- <br />ing $300 billion per year to pay for foreign oil and gas is not the re- <br />sult of failures of government energy production efforts. The U.S. <br />govemment does not produce energy. Energy is produced by private <br />industry. Why then has energy production thrived abroad while do- <br />mestic production has stagnated? <br />This stagnation has been caused by United States government tax- <br />ation, regulation, and sponsorship of litigation, which has made the <br />U.S. a very unfavorable place to produce energy. In addition, the <br />U.S. government has spent vast sums of tax money subsidizing infe- <br />rior energy technologies for political purposes. <br />It is not necessary to discern in advance the best course to follow. <br />Legislative repeal of taxation, regulation, incentives to litigation, and <br />repeal of all subsidies of energy generation industries would stimu- <br />late industrial development, wherein competition could then automat- <br />ically detemvne the best paths. <br />Nucleaz power is safer, less expensive, and more environmentally <br />benign than hydrocarbon power, so it is probably the better choice <br />for increased energy production. Solid, liquid and gaseous hydrocaz- <br />bon fuels provide, however, many conveniences, and a national in- <br />frastructure to use them is already in place. Oil from shale or coal <br />liquefaction is less expensive than crude oil at cunent prices, but its <br />ongoing production costs are higher than those for already developed <br />oil fields. There is, therefore, an investment risk that crude oil prices <br />could drop so low that liquefaction plants could not compete. Nuclear <br />energy does not have this disadvantage, since the operating costs of <br />nucleaz power plants are very low. <br />Figure 27 illustrates, as an example, one practical and environ- <br />mentally sound path to U.S. energy independence. At present 19% of <br />U.S. electricity is produced by 104 nuclear power reactors with an <br />average generating output in 2006 of 870 megawatts per reactor, for <br />a total of about 90 GWe (ggawatts) (125). If this were increased by <br />560 GWe, nuclear power could fill all current U.S. electricity re- <br />quirements and have 230 GWe left over for export as electricity or as <br />hydrocarbon fuels replaced or manufactured. <br />Thus, rather than a $300 billion trade loss, the U.S. would have a <br />$200 billion trade surplus -and installed capacity for future U.S. re- <br />C <br />~; <br />r/~ <br />a <br />:. <br />0 <br />U <br />!5 Delivered Coat <br />of Electric>tl Energy <br />!0 <br />rvrelar CoN Gu WIM Mkre Wled <br />Or Selu~ <br />Figure 26: Delivered cost per kilowatt hour of electrical energy in Great Brit- <br />ain in 2006, without COZ controls (126).
