Obama’s Administration fights against the Keystone XL pipeline extension. Because the oil price is getting lower and lower, Obama’s administration assumes that the expansion of the Canadian-American oil supplier will conduct to the oil demand growth. The fear is on expansion of Canadian tar sands, and then the increase in greenhouse gas emission. The construction of the Keystone XL pipeline is dividing Canadian and American authorities. It is thought that the result is going to be an increase of the oil demand and worsening of the greenhouse gas emission, because oil will be extract from tar sands, and this process creates more pollution than others. The further US argument is that in 5 years, oil price is going to fall down with 2 possible negatives effects. First, the increase of the oil supply will further decrease the oil price. Second, the low price of the oil makes hard a realization of profits. From January to June 2014, prices of benchmark West Texas Intermediate and Brent crude oil vacillated between about $90 and $110 per barrel. Then they fell off a cliff, dropping to about $50 per barrel as the U.S. energy boom injected huge amounts of the oil into a market already crippled by weak demand from a sluggish global economy. The pipelines opponents think that it is less expensive to ship oil through pipeline than by trucks or rail. And they suggest to American oil refineries to send their daily orders of 8 or 9 million barrels to the Canadian producers instead to the gulf producers. The Environmental Protection Agency published its statement informing that “There should be no more doubt that President Obama must reject the proposed pipeline once and for all.” The gLAWcal Team EPSEI project Tuesday, 3 February 2015 (Source: U.S.News)
