SIR – Nobody loves the big energy companies these days, but breaking them up would not on its own be enough to tackle soaring fuel bills.

As long as big banks and privatised energy firms throw money at coal, oil and gas, bills are likely to continue to rise as these fuels become more expensive, especially compared to renewables which are getting cheaper as technology advances. And as more of these harmful fossil fuels are mined, drilled and burned, more people’s land will be polluted, and the global climate will suffer.

Instead, we as a society must take back control of energy, invest in switching to renewables, and focus on providing affordable, sustainable energy for everyone.
