Crossbenchers are demanding action on energy following the Government's decision to abandon its signature policy, the National Energy Guarantee (NEG).

Key points: The Liberal Party dumped its energy policy prior to the leadership spill

However they are wary over the role of renewable energy in any potential compromise.

Liberal MP Julie Bishop, the party's former deputy leader, announced on Tuesday that she wanted her party to revive the NEG.

Centre Alliance MP Rebekha Sharkie echoed those calls and urged the Government to find an agreement with Labor, saying the industry needed a bipartisan policy for investment certainty.

"We are in a paralysing policy vacuum and the dumping by the Government of their own policy was nonsensical," she said.

"The NEG was a compromise, but we were prepared to support it."

New independent MP Kerryn Phelps declared in her maiden speech on Monday that Australia was running out of excuses for failing to respond to climate change.

Yet she still backed the NEG, which aims to strike a balance between reducing energy bills and reducing carbon emissions.

"The NEG is one way that could provide much-needed certainty and reliability for the energy sector," she told the ABC on Tuesday.

"It may not be perfect but it is better than the policy vacuum of the current Government."

Renewables a key issue

Tasmanian independent MP Andrew Wilkie was critical of the lack of ambition in the renewable target as part of the NEG put forward by the Liberal Party.

He indicated to the ABC he would want to see the detail of any updated policy before deciding on his position.

Labor has pledged a more ambitious renewables target as part of its energy policy compared to the Government's proposal, but it would use the same mechanisms to encourage energy retailers to lock in sustainable and reliable supply.

Greens MP Adam Bandt urged Labor to reject the promise of bipartisanship and wait until it was in Government.

"Instead of doing a deal with the Liberals, who clearly don't take the climate threat seriously, Labor should wait until after the next election and put in place an ambitious climate policy," he said.

"Any deal done now with the Liberals is likely to lock in coal and make life harder for renewables."

Since the NEG was scrapped, Victorian independent MP Cathy McGowan has been pressuring Prime Minister Scott Morrison to pursue a responsible energy policy that includes enough support for renewables.

Former Liberal MP Julia Banks, now sitting on the crossbench, has previously spoken in support of the NEG.

Bishop speaks out

Labor announced it would adopt the NEG policy last week.

The party's energy spokesman Mark Butler said today the NEG was "the last best chance to get a bipartisan agreement to find a way out of the energy crisis that has emerged".

He was responding to Ms Bishop, who has called on her party to support the NEG.

She said electricity generators needed long-term certainty to give them confidence to make large-scale investments.

"The Government needs to consider energy policy through the prism of securing bipartisan agreement with Labor, to establish a long-term, stable regulatory framework that will support private-sector investment in generating capacity," she told the Australian Financial Review.

The Liberal partyroom actually supported the NEG, but Malcolm Turnbull abandoned the policy after backbenchers threatened to vote against it.

New Energy Minister Angus Taylor has moved away from the NEG and declared his priority is power prices, focusing on more regulation of power companies.
