Frac away, boys, enjoy!

Fifty years to so-called "clean energy".
The U.S. is covered by a network of old, tired pipelines leading to the Gulf coast and the major refineries. The Keystone will lead to the closure of some of these.
A diversion away from the Ogalalla and the Sand Hills, approved by Nebraska. Portions of the Keystone are already up and carrying.

The bitumen sands of Alberta-Saskatchewan hold an estimated 60 years of U.S. oil needs.
The Kearl mega-billion project starts moving product next year, regardless of Keystone completion. http://www.imperialoil.ca/Canada-English/operations_sands.
This is just one of the new projects going online. If not to the U.S., to the Pacific and China.

The Keystone Project is the logical solution for the U.S. and the industrial growth of the States. Otherwise surrender to China, India, South Korea and Indonesia.
