Because transportation is such a large contributor to global warming, both globally and in the United States, climate and energy experts say finding clean alternatives to gasoline is also key to replacing fossil fuels and slowing global warming. Just as there is debate and competing research about which type of alternative transportation fuel should be developed to produce electricity, however, there is also competition among possible new transportation fuels. So far, in the United States, significant funding has been put into two transportation technologies—ethanol and hydrogen fuel cells. Many energy commentators say cars powered by electric batteries are the technology closest to mass production capability, however. (more…)

At present, in the United States and worldwide, motor vehicles are fueled almost exclusively by petroleum based gasoline (or reformulated gasoline) and diesel fuels. Since the first oil price shock in 1973, efforts have been made to seek alternative fuels to displace gasoline and diesel fuels and achieve energy and environmental benefits. Some of the alternative fuels that have been researched and used are liquefied petroleum gas (LPG), compressed natural gas (CNG), liquefied natural gas (LNG), methanol (MeOH), dimethyl ether (DME), Fischer– Tropsch diesel (FTD), hydrogen (H 2 ), ethanol (EtOH), biodiesel, and electricity. Production processes associated with gasoline, diesel, and each of these alternative fuels differ. (more…)

Prior to the Clean Air Act of 1990, environmental issues regulations were aimed at reducing emissions as they left the exhaust system. The catalytic converter has been the primary means of attacking air pollution in this way. After 1990, regulations for the first time undertook to alter the composition of the fuel itself. Reformulated gasoline applies to gasoline that is sold in the nine metropolitan areas designated by the EPA with the highest level of ozone in air pollution problems. About 48 million people reside in areas where ozone concentrations exceed federal standards. (more…)

The development and blending of gasoline additives and petroleum additivies are undertaken for the most part by the petroleum refining industry. Additives are essential to the economic well-being of the industry because they tend to boost sales for gasoline fuel and diesel fuel. In most cases, gasoline additives do not differ in price by more than three to four cents a gallon. The recently developed additives do not necessarily sacrifice fuel efficiency and fuel savings for higher octane numbers. They are multifunctional. In addition to boosting octane ratings they may also clean the engine, which, in turn, leads to greater fuel efficiency. (more…)

Whatever the actual motivation, American policymakers perceived a need after 1973 to restrict automobile and light truck consumption of gasoline. How The Energy Policy and Conservation Act of 1975 imposed Corporate Average Fuel Economy (CAFE) standards on all auto and light truck manufacturers who sold vehicles in the Unite d States. The weighted average of miles per gallon (MPG) for each manufacturer’s car sales was required to be at least 18 MPG by 1978 and 27.5 MPG by 1985. Manufacturer s that failed to meet this standard were to be fined $50 per vehicle sold for each gallon (of MPG rating) by which they failed. (more…)

There are many possible reasons for suspecting market failure in a product like gasoline. Throughout the world, the exploration, refining, and selling of petroleum products has long been controlled by large firms in oligopolistic or monopolized national markets. The United States is a sufficiently large importer of oil that it could have monopsony power, which would mean that we could increase the welfare of our own citizens by reducing our imports. Moreover, the consumption of petroleum products, especially in motor vehicles, generates many negative external costs, and will begin to examine closely in the next chapter. Where there are negative externalities, a free market will overproduce and over consume. (more…)
