Issue 3
a) I highly doubt that major oil companies, such as Exxon and BP, will ever seriously develop and support alternatives–not until the world has been sucked dry of oil. They’re getting real money from their oil enterprise; why would they try to change something that brings in the excessive profit? They wouldn’t. The CEOs are still money-oriented. They know the people are unwilling to shift from cheap, easy fuel; that’s what they mean when they say, “No one is beyond petroleum.” As a nation, our main source of fuel comes from petroleum, and we take pride in that.
b) The Heartland Institute and the Competitive Enterprise Institute are considered “denial groups,” or groups that do not believe global warming is happening, and who believe that excessive carbon dioxide emissions are okay–”they are a part of life” says one groups commercial. Exxon agreed with these groups and did not think climate change was happening. When confronted about how much money they are putting in to searching for alternative energies, Exxon replied that they thought they were doing enough. Although they were not putting much money in, they said that they offered enough money for research. Also, they said that no matter how much money they put in, some would always say they could put in more. Now, Exxon is trying to address climate change not because they want to, but because the shareholders and investors think that addressing climate change is the best thing for the company. They wanted Exxon to change course and attempt to bring down its carbon footprint. This makes Exxon in an awkward place with the climate change denial groups (Heartland Institute and Competitive Enterprise Institute) because Exxon has completely changed its mind. They are considered hypocrites which is another reason why some scientists are cynical about their efforts. After all, they are only making efforts to gain more money from investors. Exxon and other oil companies try to advertise as being environmentally conscious to gain the support from the public. Personally, I do not think that these oil companies will ever throw a significant amount of their profits behind alternatives because if there are more alternatives, then gas will not be in demand as much and therefore the companies will not be earning as much money.
c) Currently, up to 1.2 million barrels of oil are produced from the tar sands every day. The goal of 5.3 million bdp could be reached by 2020.
However, oil from the tar sands is much more difficult to extract than the conventional oil. This oil is found in the ground in the form of bitumen, a hydrocarbon that is solid at normal temperaturesand mixed in ith sand, water, and clay.
There are two processes to extract this form of oil and both are harmful to the earth’s atmosphere.
Surface mining, which requires cutting down trees, must be done to expose layer of bitumen in the ground. Two tons of this material equals only one barrel of oil. This process destroys the local ecosystems, leaving open “pit mines” about 75 meters deep.
The other process is in-situ mining; a technique needed to reach about 90% of the bitumen. This process requires high pressure steam to increase the bitumen’s viscosity and seperate the oil from sand. Heating the water to produce the steam requires large amounts of natural gas. “Tar sands mining requires 750 cubic feet of natural gas for each barrel of oil.” The production of this oil uses large amounts of cleaner, nonrenewable gas to produce a dirtier gas. It just does not make sense why the companies would want to forgo using a cleaner gas, and instead use this to make a dirtier gas.
Both processes are water intensive, using about 3 and 7 barrels of water per barrel of oil. A large percentage of this water ends up in large tailing ponds with toxic materials. An average of 2 to 4.5 barrels of water are used to produce one barrel of this oil. This is seriously lowering the water levels in Canada. Toxic water from the production of the oil has infected fish and other wildlife. This toxic water has also caused sickness among the Aboriginal people that live near the production sites
Also, with oil prices reaching as high as $90 a barrel, extraction has become very expensive. In addition to the overall cost, oil sand extraction is highly energy intensive.
The most alarming statistic was learning about how the production of tar sands release about three times more greenhouse emissions than pumping conventional oil. If this continues, the tar sands industry will be the largest producer of greenhouse gases of all the industries in Canada. “The tar sands consume as much gas every day as is needed to heat half the homes in Canada.” Clearly, tar sand and shale production is an inefficient way to make a dirtier oil to use in our homes. Why not invest in cleaner, more efficient energy sources?
