Electric utility deregulation offers the great promise of market forces leading to lower electric rates, lower air pollution environment, greater energy (and economic) efficiency, and perhaps greater use of renewable energy sources. Ideally, deregulation involves the restructuring of a previously monopolized or nationalized electric utility into separate generation, transmission, distribution, and marketing companies, and allowing wholesale and retail choice of generation company or power marketer. Deregulation has occurred to varying degrees since 1989 in the United Kingdom, Norway, Australia, New Zealand, Chile, Argentina, and about 20 states in the United States. There have been promising results in a few countries and in some U.S. states in some respects, especially lower rates and lower air pollution problems. In most cases, competitive markets have yet to be realized and lower rates can be attributed to other causes, such as previously planned amortization or retirement of expensive power plants, unexpected surplus in natural gas, rate caps, etc. In addition, deregulation has had only a slight beneficial effect on the use of renewable electricity sources. The promise of electric utility deregulation is thus unfulfilled and deserves further study.
Geopolitical considerations have played a major role in many renewable energy policy decisions, e.g., in domestic debates over gasoline taxes, pipeline construction, radioactive waste disposal, and acid rain control legislation in the United States, and in petroleumrelated violence in Nigeria. The most prominent role for geopolitics in energy policy has probably involved international discussions on controlling greenhouse gas emissions, and in oil markets. In the cases of the Kyoto Protocol of 1997 and the 1992 Framework Convention on Climate Change, nations carefully considered their national economic interests, domestic politics, and international trade during the negotiations. European countries, with the lowest rates of population and economic growth along with strong domestic environmental lobbies, have pursued a greater rate of greenhouse gas reduction.
The United States, in contrast, has been stubbornly cautious and backed out of the treaty in 2001 (arguing it is not in its economic best interests), and the oil-rich nations of the Middle East have been least supportive of any emissions controls. In the case of oil markets, with the United States now dependent on imports for over half its supply, energy policy and trade strategy have played major roles in the pursuit of new oil discoveries in Alaska and in warfare in Kuwait, Iraq, and perhaps Afghanistan.
air pollution problems created by coal combustion. Meanwhile, coal-fired power plants and industrial boilers spewed out tons of gaseous and particulate pollutants into the atmo- sphere. During combustion, the small amounts of sulfur and nitrogen in coal combine with oxygen to form sulfur dioxide (SO2), sulfur trioxide (SO3), and the oxides of nitrogen (NOx). (more…)
The spark-ignition and compression-ignition engine and internal combustion engines technologies that are currently employed in motor vehicles were developed more than 100 years ago. These conventional vehicle technologies are fueled by petroleum-derived gasoline and diesel fuels (the socalled conventional fuels). Over the past 100 years, the conventional technologies have been dramatically improved, reducing cost and increasing performance. (more…)

The operations on-board an oil tanker transportation are radically different from those on other types of ships, primarily due to the physical properties of the cargo. The entire cargo operations are highly automated and proceed with no one on-board the ship or shore seeing the cargo physically. Even minor misunderstanding of an order or a miscalculation can cause a major spill in pristine locations. By the same token, a tanker crewed by properly trained seafarers under good management could very well be the safest ship afloat. Although most tanker voyages today are completed safely and go unreported, even a minor tanker pollution accident often gets widespread attention from the media, and the image of a polluted beach laden with dead flora and fauna is a sad and telling picture.

Designers in China have launched the first wind turbine levitating in the world of permanent magnetic levitation (Maglev) in the Wind Power Asia Exhibition 2006.
Considered a key step in the evolution of global wind power technology and a notable advance in independent intellectual property rights in China. The generator was jointly developed by the Institute of Energy Research of Guangzhou in the Chinese Academy of Sciences and Guangzhou Hengyuan Energy Science & Zhongke Technology Co., Ltd. (more…)
Mustard and sausages are a couple indestructible material. This dressing made from seeds of Brassica plants is inevitable in most hot dogs, hot dogs, according to the country we are. However, a group of Argentine scientists is to demonstrate that mustard also has other elements function utilities. (more…)
Do we have the resources? Rudolf Diesel developed the diesel engine which ran on biodiesel vegetable oil in the late 1800s. At the time, he speculated that his discovery seemed insignificant, but later could prove to be as important as mankind’s uncovering of future energy uses for petroleum and coal tar. Given the U.S.’ rapid expansion into biofuels, it would appear his vision was correct due to the drawbacks of biofuels. But widespread adoption of biomass-based fuels is not a foregone conclusion. Two questions haunt its progress. First, will it truly reduce U.S. reliance on fossil fuels? And second, is there enough farmland to accommodate widespread production, without jeopardizing food supplies? (more…)
Foundations have made good progress on the energy front, but huge gaps remain. Promising technologies in energy production and use today prove that the prospects for an affluent but low-carbon society are good. But the U.S. and the world economies continue to run primarily on oil and coal. As the largest consumer and producer of energy in the world, the United States has the responsibility to lead the transition to cleaner energy technologies. (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…)
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…)
