Primary Energy Use and Clean Coal Technology

clean coal technology
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.

Flex Fuel Vehicles Auto Industry Ford, Chevrolet, Honda, Toyota, and Nissan

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…)

Alternative Transportation Fuels And Alternative Fuel Vehicles

Alternative Fuel Vehicles
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…)

New Car Tax Credit Promoting Higher Fuel Economy in Japan

new car tax credit
This latter form of new car taxes can actually serve as an impediment to higher fuel economy to the extent that increased energy efficiency is attained with high-cost technology, such as continuously variable automatic transmissions, hybrid electric vehicles drive trains, and variable valve controls, and such taxes add to the cost of these technologies. (more…)

Fuel Taxes in Europe to Reduce Fuel Consumption

Fuel Taxes in Europe
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…)

Sulfur Gasoline as Source of Automotive Emissions

In recent years, there has been a greater understanding of the role of automotive emissions as environmental pollutants. Sulfur dioxide, nitrogen oxides, and carbon monoxide degrade the earth’s atmosphere and are health hazards. Carbon dioxide adds to the atmospheric buildup of greenhouse gases and in turn accelerates the process of global warming. (more…)

Alternative Fuels and Vehicles Cost-Competitive

alternative fuels vehicles
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…)

Reformulated Gasoline Fuel and MTB

reformulated gasoline fuel
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…)

Gasoline Additive: Fuel Efficiency and Reduce Automotive Emissions

gasoline additive
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…)

Reducing the Use of Gasoline | Corporate Average Fuel Economy

gasoline consumption

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…)
