Prime Minister David Cameron has criticised Labour's plan to freeze energy prices, but maintains he wants to see low energy bills for 20 years to come.
Speaking at a PM Direct event in York, he said it was important to work on using new sources of fuel.
"I want to see energy bills low not just for 20 months, I want to see them low for 20 years," he said.
