Explain why oil exploration in the areas shown could lead to high economic and environmental costs. (10) Oil exploration in the areas show brings many environmental and economical challenges with it. The economic cost can be very high due to the extraction techniques used as in the majority of the areas highlighted there are extraction issues due to technical difficulties such as unconventional oil, such as the Canadian Tar Sands and deep water see oil, such as in the Gulf of Mexico which is hard to access. The extraction costs for both these methods is very high and would need high oil prices to see a good return economically. To add to this these methods need vast amounts of energy for extraction, causing the high extraction cost and with this also pollute greatly as the oil is extracted and so raise CO2 and other GHG emissions before the fuel is even burnt.
Another global player are the OPEC nations. These nations have major reserves of oil, therefore can set the price of oil in its member countries. This has led to prices of oil changing, having periods of very high prices and periods of very low prices. For example, Saudi Arabia has 22% of worldwide oil reserves, meaning they can sell their oil globally to countries with smaller oil reserves meaning they can make a large profit. Nationally, different Governments are involved in the global supply of energy.
When the clutches and bands can’t fully lock the shafts in place the transmission begins to slip. Low fluid in the transmission creates rapid wear of the friction plates and extreme fluid temperatures. Additionally, automatic transmission failure can be caused by abuse. Towing too much weight causes extra stress on the
Methanex had become the world’s largest producer of methanol, with production and trade all around the world. It became successful in large part due to its cost leadership by continually seeking remote locations where natural gas was stranded, and also due to its reliable delivery by developing its own Waterfront Shipping Company. By 2012, Methanex produced roughly 7 million tonnes of methanol, taking about 16% of the global market share. However, Methanex was faced with strategic issues at this moment from both demand and supply sides. In the demand side, Methanex’s revenue was exposed to the fluctuation of the demand for methanol, since Methanex only produced methanol.
The consequence of climate change is serious. It will cause sea level rises，more flooding and stronger storm. Secondly, the shortage of fossil fuels is also a big problem, which is means fossil fuels are finite and non-renewable. If people cannot use them reasonably and economically, fossil fuels will be used up very soon. Klass model is a good illustration of this problem and it assumes a continuous compound rate and computes fossil fuel reserve depletion times for oil, coal and gas of approximately 35, 107 and 37 years, respectively (Shahriar & Erkan, 1).
Acid rain as a result of industrialization has had many negative effects on the New England region in particular. The Adirondack Mountains are of special interest due to their soil composition that does not allow for the seizure of the two primary particles in acid rain. This has caused issues pertaining to the water reservoirs in the area that now are sometimes unable to support life do to the high acidity. Acid deposition as it is more formally called is typically composed of sulfur dioxide and nitrogen oxide. These two components are naturally occurring from sources like volcanoes but the industrial revolution has exponentially increased the amount of these chemicals in the air.
Fossil fuels, those substances that move our cities, communicate our countries, make our life style possible, those precious elements we all know, are nonrenewable resources. In reality this is not the real issue, it is something that we cannot control and that anyway is going to happen; the problem is, what are we going to do after that happens? “Oil peak is the point at which irreversible decline of oil supplies around the world begins.” “This is based in the M. King Hubbert's theory that explains that as an oil field, that reaches its maximum and then its production rapidly declines until nothing is left, the earth´s oil supply will peak and this will lead us to a terminal decline of the availability of this resource”. Even though it is
The inefficient engines consume too many resources so that people are anxious about that. In addition, the pollution is more and more serious in terms of the waste from engines, especially on the greenhouse effect by the exhaust gases of engines. Therefore, engines seem dangerous to the society and the earth. Although they have some negative influence on the environment and resources, it is doubtless that engines are more and more efficient with the development of technology and have changed people's life and history. Admittedly, in some engines such as atmospheric engines and hydrogen engines, they have little waste to exhaust.
Burning coal, petroleum and other fossil fuels at extremely high temperatures is the primary means by which electricity is produced. This leads large amounts of pollutants in our air and water. The atmosphere already absorbs a ton of greenhouse gases naturally, but is trapping up to 25 percent more of the sun's radiation due to annual increases in
oil spills Crude oil is a major energy provider for the world today; but when accidents happen, crude oil becomes a major pollutant for our world. An oil spill is an accident that occurs when a transport vehicles, oil rigs, pipe lines, or tankers have malfunctions and release oil into the surrounding environment affects the surrounding area. There are two types of oil spills: those occurring on land, and those in water. Land spills can usually be contained and cleaned up easily, while oil spreads and becomes more dangerous in ocean spills. Oil spills have a number of effects on the environment and economy.
