Transportation is another sector that has increased its relative share of primary energy use. This sector has serious concerns as it is a significant source of CO2 emissions and other airborne pollutants, and it is almost totally based on oil as its energy source. An important aspect of future changes in transportation depends on what happens to the available oil resources, production and prices. At present, 95% of all energy for transportation comes from oil.

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…)

Analysis of future light-duty transportation energy use require estimates of the impact of fuel prices on travel and fleet fuel economy, estimates of the fuel price elasticity of travel, fuel economy, and fuel consumption are ubiquitous in the literature. However, there is substantial disagreement about the magnitude of these elasticities because travel volumes, fuel economy, and fuel consumption are dependent on several variables other than fuel price and because fuel prices have tended to be volatile during the past few decades, thereby complicating attempts to estimate long-run elasticities. Thus, the magnitude of the effect of changes in fuel taxes in US on fleet fuel economy and on travel volumes and fuel consumption is also subject to considerable disagreement. (more…)

The increase in the prices of major fuels, like gasoline and diesel fuel products is a major global problems recently. Those prices are increase associated with the global economic crisis. Now, it is the ideal time to move all the focus and effort to alternative fuels for vehicles. There are different types of alternative energy sources for fuel to choose from. But the hard fact is that the areas of alternative fuels have not passed many real qualitative and quantitative surveys and breakthrough research. (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…)

If you are not up-to-date with scientific developments, you probably have not have heard of the process of converting gas to liquids. It might not sound like it could apply to many people, but in fact it should appeal to everyone. This newer method of using our natural resources to our advantage could be the key to less reliance on foreign energy sources, resulting in lower natural gas prices. (more…)

Natural gas is found mainly in underground reservoirs and in coal beds. Natural gas is a fossil fuel that consist primarily of methane and some smaller amounts of hydrocarbons subtracts like ethane, propane and butane. There might be some inert gas like nitrogen, helium, and carbon dioxide involved and dissimilated into natural gas. The actual mixture composition is varies depending upon the region where that natural gas is found. (more…)
