They've been trying to build one for years (Keystone XL) but have been stonewalled at every turn by Obama.
Not just Obama, but the by anti-oil people. They think by blocking the pipeline, they will be reducing CO2 in our atmosphere. The sad part is, they are actually INCREASING the amount of CO2 and other pollutants.
Rather than move the oil from Canada to Texas via an electric powered pipeline, they are forcing the oil to be loaded onto trains, where they are transported to a port where they are loaded onto an oil tanker where they will be transported to China. All of these modes of transportation are diesel powered. Once in China, they will be refined by Chinese workers under Chinese environmental regulations into various petroleum products. Then they are loaded back onto tankers and shipped around the world, with all profits going to the Chinese government.
Or, we could transport the oil to Texas refineries, where we have control over the emissions the refineries emit, by a pipeline using electrical pumps.
Tell me which option makes more environmental sense (not to mention the economic sense!)
