After taking a months-long break from energy negotiations, senators appear poised to restart debate on some of President Obama's so-called bite-sized pieces of energy legislation.

The "chunk" of energy policy that has gotten the most buzz in recent days is the proposal for a "clean energy" mandate, which Obama touted high up in his State of the Union speech last week.

The idea would require utilities to generate a certain percentage of their electricity from low-carbon sources, like renewables, nuclear or "clean coal." The president's promotion of such a policy in his prime-time address buoyed the hopes of many environmentalists and renewable energy advocates who had all but given up on seeing substantial energy legislation move through the closely divided Senate or Republican House this year.

But such a proposal still has naysayers. And the details are far from finalized.

For one, the White House and Congress have yet to firmly establish which energy sources would be considered "clean" under such a mandate. And Obama's proposal to produce 80 percent of the nation's electricity from clean sources by 2035 is seen by some would-be champions on Capitol Hill as being too aggressive.

It also lacks the full-fledged support of some of the chief negotiators on energy issues in the Senate.

Energy and Natural Resources Chairman Jeff Bingaman (D-N.M.), who historically has been opposed to such a measure in favor of mandates limited to renewable energy sources, last week said he was "anxious" to work with the Obama administration and others in Congress to "come up with a proposal that does what the president outlined."

"I never felt it was a bad idea; I just haven't seen a concrete proposal yet that I thought was workable and made sense," Bingaman told reporters last week (E&ENews PM, Jan. 26).

He may offer more insight into his position on a CES this afternoon when he delivers remarks about his energy policy priorities during a luncheon hosted by think tank NDN.

Sen. Lisa Murkowski (R-Alaska), the panel's ranking member, likewise has not signed onto the idea of a CES despite having supported a broad energy bill in the last Congress that included language to create a renewable energy standard that would limit the mandate to renewable sources.

And Obama's proposal could face resistance from more conservative Republicans, who campaigned on limiting government regulation.

But the idea of a clean energy standard does have champions on Capitol Hill. Sen. Lindsey Graham (R-S.C.), for one, is backing the idea. Once a chief negotiator on sweeping climate legislation, Graham late last year floated language that would have set targets of 25 percent clean energy by 2025 and 50 percent by 2050, targets that Energy Secretary Steven Chu said were viable.

Sens. Tom Carper (D-Del.) and Mark Begich (D-Alaska) also have noted their willingness to work on a CES measure in the past.

Graham has also said he is working on a measure that would expand access to domestic reserves of oil and natural gas.

"I'm trying to come up with a clean energy standard, and also energy independence initiatives," Graham said. "They're not illogical. We have to find more domestic oil and gas, but at the same time we need to be pushing more clean energy, because that's our ultimate break from dependency on fossil fuels" (E&ENews PM, Jan. 28).

Oil spill, efficiency measures

A CES is not the only energy piece to gather buzz in recent days.

Last week, Sen. Robert Menendez (D-N.J.) reintroduced a measure that would eliminate the liability cap for oil companies involved in a spill. The language, which caused dissension among Republicans and oil-state Democrats last year, ultimately contributed to the demise of the Democrats' energy package last summer.

But after the bill stalled, Menendez vowed to work with some of the measure's harshest critics -- Begich and Sen. Mary Landrieu (D-La.) -- to come up with compromise language. Earlier this month when he announced plans to float a new measure, Menendez said he would work with other senators "who have constructive ideas to help it pass."

Such a compromise on liability could resurrect talks on oil-spill response legislation, something Bingaman had listed as a top priority in the final months of the 111th Congress.

Another priority of Bingaman's last year that likely will crop up in energy discussions this year is energy efficiency.

Sen. Jeanne Shaheen (D-N.H.) is prepping a package of efficiency measures to float in the next few weeks, an aide said.

Her legislation will reflect many of the same efficiency priorities as the broad energy bill that passed out of the Energy Committee last Congress. Specifically, the package will address appliance standards and Energy Department loan guarantees, among other issues.

Late last year, Bingaman listed efficiency as one of his top priorities, along with a renewable energy standard and oil-spill response legislation. His presentation this afternoon likely will reiterate those priorities with the possible substitution of a clean energy standard for the RES.

Energy markets

Bingaman's committee later this week will focus on the energy and oil market outlook in a hearing that could have implications on oil and gas policy.

Increases in oil demand this year are expected to keep crude prices rising, which could prompt calls for more domestic production of oil and gas.

Schedule: The hearing is Thursday, Feb. 3, at 9:30 a.m. in 366 Dirksen.

Witnesses: Richard Newell, administrator, Energy Information Administration; Nobuo Tanaka, executive director, International Energy Agency; Roger Diwan, partner and head of financial advisory, PFC Energy; and Jim Burkhard, managing director, Cambridge Energy Research Associates.
