The individual heading the Liberal Party’s energy review has suggested that incorporating more coal and nuclear power is essential for reducing energy costs.

The party is set to convene on Wednesday to deliberate its position on net zero emissions. However, tensions are rising as leading party members threaten consequences if their demands are not met.

Despite the internal disagreements over climate policy, especially following the Nationals’ decision to abandon the emissions-reduction target, recent polls indicate that the Liberal Party’s popularity with voters remains unaffected.

Dan Tehan, the spokesperson for energy and emissions reduction, has been advocating for a strategy centered around “energy abundance” as part of the Liberals’ energy review initiative.

This strategy hinges on prolonging the operational life of aging coal-fired power plants, many of which had planned closures announced during the Coalition’s governance.

“In the same period I think 24 of the 28 coal fire power stations announced or bought forward their closure date,” Labor Senator Jenny McCallister told Sky’s Sunday Agenda.

Conservative Liberal MPs say ditching a net zero carbon reduction pledge will bring prices down. Moderate party members say the opposite.

“Net zero if done properly could reduce power prices and should reduce power prices over time,” Liberal Senator Andrew Bragg told the ABC’s Insiders.

“I think there’s a way through this … the Liberal Party has a plan from the National Party now,” Nationals leader David Littleproud said.

Tehan compared it to “threading a needle”.

“Who went first and who went second, who cares?” he said.

Mcallister said Australians had “already paid the price for the unbelievable division within the coalition over this.”

The November Resolve Political Monitor has Labor ahead 53-47 on a two-party-preferred basis. It is a comfortable lead but the margin is tightening.

Voters were asked their number one issue and 42 per cent said keeping the cost of living low was the priority.

Crime and anti-social behaviour was next with responses in the single digits.
