SIR – The Prime Minister has blamed higher bills on measures to invest in green energy and energy efficiency.

According to the Government’s own Climate Change Committee, set up to provide independent guidance, of a typical householder’s rise of £520 between 2004-2012, £35 is due to low-carbon support with another £45 for energy efficiency.

The main reason families are paying more is the increasing wholesale price of gas, which is expected to rise by 40 per cent over the next few decades.

The best thing we could do to cut bills in the long term would be to move away from gas and invest seriously in renewables.

Nuclear power is also increasingly expensive yet the Government is happy for bill payers to fund a lavish subsidy for EDF.

By contrast, renewable technologies have seen dramatic price falls over the past few years.

If the Government really wants to help families struggling with bills they should put in place measures to insulate homes up and down the country.

This could be funded by a windfall tax, and would create hundreds of thousands of jobs.
