 is missing the point. Our purchase of American gas is a temporary stop-gap in advance of bringing in more wind generation – which can be delivered quicker and at much lower cost than fracking. It also has a lower environmental impact and is less politically sensitive. Why we didn't start fracking years ago is a separate question. We have to live, and make decisions, in the here and now. Michael GaineSaffron Walden, Essex SIR – Sadly the numbers don't add up for tidal power (Letters, November 7). It can make a significant contribution to our energy requirements but will never amount to more than a minority share. The big non-fossil energy hitters are offshore wind and nuclear power.

SIR – However laudable the long-term cause of the Just Stop Oil demonstrators may be, their methods are serving only to alienate potential supporters, who are being denied their right to go about their lawful business.
Even if Britain were to cease to produce emissions, the global effect would be negligible. Shouldn’t the protesters be targeting China, India or America? Their current actions are little more than gesture politics.

SIR – When police close the M25 for safety reasons because a protester has clambered on to a gantry, just whose safety is taking priority?
Is it the safety of the protester or the safety of – for example – a person trying to get to hospital?
