WASHINGTON — The chances for a Senate vote to approve the Keystone pipeline died Monday along with an energy efficiency bill, victims of Congress’ inability to enact energy policy.

The Senate, paralyzed by partisan bickering, has not been able to pass a major energy bill since 2007, and it now appears unlikely to do so before the November election.

Senate Majority Harry Reid, D-Nev., had agreed to schedule a vote on whether to force President Barack Obama to approve the controversial Keystone XL pipeline from the Canadian oil sands to the U.S. Gulf Coast, a key issue in election races around the country. But Reid said he would only allow that vote if the Republicans agreed to the modest energy efficiency bill, which has bipartisan support.

Senate Republicans, though, insisted on offering amendments to the energy bill – including measures to help the coal industry by limiting regulation of greenhouse gases and to speed up approval of U.S. natural gas exports. Reid refused to allow amendments to be considered on the floor.

The Republicans in return threatened a filibuster of the energy bill, killing it and Reid’s offer for a vote on Keystone.

Reid claimed the Republicans broke deals and held hostage the energy efficiency bill, sponsored by Sens. Jeanne Shaheen, D-N.H., and Rob Portman, R-Ohio, to offer incentives for energy-efficient homes and buildings; it was introduced in 2011.

Senate Republicans, though, said they never had any deal with Reid and simply wanted their amendments to be considered. They said that, given how rare it is for an energy bill to reach the Senate floor, they had the right to debate energy policy.
