Palin's Pipeline Raises Questions

"Where the natural gas from the Alaska Natural Gas Pipeline will end up is a murky question tied up in a 30-year-old treaty, expansion of Canadian tar sands operations, and trends in natural gas supplies both in the United States and in Canada.

Environmentalists fear at least half of the relatively clean-burning Alaskan North Slope gas will end up fueling tar sands operations in Alberta, where the pipeline will end, instead of coming to the lower 48 states to replace carbon-intensive coal in power plants. The tar sands operations already consume about 20 percent of Canada’s natural gas, and they are expected to need as much as twice that by 2035. "
