Sir – Your article about the cuts to the Feed-In Tariff (FIT) for new domestic producers of renewable energy failed to make clear the even more draconian cut in FIT imposed on early adopters of the technology by the last Labour government.

Those of us who embraced the technology in its early days now receive only 9p per unit produced, compared to the 21p offered to those suffering the latest cuts in FIT. I don't recall Friends of the Earth offering to mount any legal challenge on our behalf.

A single FIT tariff for all would at least be easier for the generating companies to administer, and should always be funded by a levy on other electricity consumers.

In those circumstances the equation for the Government would be the cost of Jobseekers’ Allowance from any lost jobs in the renewable market, versus the stimulus to the economy from the jobs created by the renewable energy industry. Cutting the FIT tariff might actually cost the Treasury money.

A new compromise rate of 30p, rising at the rate of inflation each year, might be worth fighting for, and would provide benefits for both sides. At that rate, investment in renewable energy would still produce a far better return for householders than any other use of their savings.

Encouraging mortgage providers to provide the new capital for projects could also help to keep the markets thriving.

What is needed is a bit more political determination from the energy secretary, and less willingness to take the first option presented by officials.
