Kemi Badenoch will launch a campaign calling on Britain to maximize the use of its oil and gas reserves.
The Conservatives will put the “Get Britain Drilling” campaign at the center of their proposals to reduce the rise in energy prices caused by the war in the Middle East.
The Iranian blockade of the Strait of Hormuz has caused oil prices to rise sharply around the world.
Conservative leader Mrs Badenoch and her party initially called for Britain to join the United States and Israel in their war against Iran.
They have since focused on calling on the UK to tap into its oil and gas reserves to prevent price rises, although ministers argue the internationally set price will not be affected by such action.
Now Ms Badenoch will launch a three-point plan to “get Britain drilling”, including ending the moratorium on new oil and gas licences, scrapping windfall tax on energy profits and more financial support for the fossil fuel industry.
Launching the campaign, the opposition leader said: “Labour’s ban on new oil and gas drilling licenses was stupid when they included it in their manifesto – in the middle of an energy crisis it is complete madness.
“Extracting our own oil and gas is a matter of energy security, financial security and national security.
“It's more employment, it's good for business and it provides tax revenue that could be used to reduce bills.”
At this week's First Minister's Questions, Ms Badenoch pressed Sir Keir Starmer to approve new licenses to drill in the North Sea, including at the Rosebank and Jackdaw sites.
Sir Keir insisted this should be decided by the Energy Secretary.
The Conservative leader said the Prime Minister's response showed he had “let the cat out of the bag”, adding: “The real reason Labor is rejecting new furloughs is because Ed Miliband now runs the Government.
“We need Britain to drill.
“A strong economy depends on abundant, cheap energy.
“Only conservatives are serious about creating a stronger economy and country.”
Mrs Badenoch plans to visit an oil rig off Aberdeen on Monday as part of the campaign launch.
The Conservative Party plans to announce new measures next week, aimed at both reducing living costs and businesses' energy bills.
But Tessa Khan, chief executive of campaign group Uplift, said the Conservatives' plan would do nothing to reduce the bills.
Referring to research suggesting hundreds of North Sea licenses granted under the previous government had produced only the equivalent of 36 days' worth of gas, Ms Khan said Ms Badenoch was “selling a dangerous fantasy”.
He said: “Politicians who refuse to acknowledge the reality of the North Sea decline are endangering our security and our economy. Not only that, but they are also betraying workers who need secure, long-term jobs, which will only now come from renewable energy, not a pipe dream.”
“This is a dull political game at the expense of ordinary people.”
Energy Minister Michael Shanks said: “Kemi Badenoch wanted to plunge Britain headlong into war without a second thought about the consequences. She has proven completely unfit to hold senior positions throughout this crisis.
“Badenoch's Conservative Party left families with skyrocketing energy bills, and failed to deliver energy security during their 14 years in power. Their own shadow energy secretary admitted new licenses in the North Sea would not shave a penny off bills.
“Tories and reformers want to outsource Britain's energy security to fossil fuel markets over which we have no control. Meanwhile, Labor will cut bills next week and invest in clean, local energy to cut bills for good.”
