SIR – Our fuel bills are rising fast, and politicians seem to have little idea what to do about it.

Tackling the profit-hungry energy companies has to be part of the answer.

But the banks, too, must be made to change their ways.

In years to come, coal, oil and gas prices are certain to carry on rising, while the cost of renewable energy will fall as long as we invest in infrastructure.

Despite this, the big banks put billions into dirty fossil fuel projects – many of which pollute and destroy people’s rivers and forests in developing countries – while their investments in renewables remain tiny.

We need ways of financing, producing and distributing energy that are good for people everywhere, and not geared solely towards maximising corporate profit.
