MY home, like most in Scotland, is heated (efficiently) by a gas boiler but it was built in an era when insulation was not given today’s importance. Our piecemeal attempts to tackle energy efficiency have resulted in only limited improvement.

A radical, disruptive and costly retrofitting is required to achieve insulation levels possible with new builds. There are very many homes across Scotland in the same category as ours.

The burning of fossil fuels is causing global warming, so gas boilers will be phased out. This I support, as most people polled do. However, when the costs and limitations are understood, the same polling indicates a minority support for conversion to alternatives.

This dislocation is what Rishi Sunak is trying to exploit for his own gain. If anyone is faced with a choice of keeping their family warm tonight or worrying about the future effects of climate change, there will only be one winner. What is required by those of us, including myself, concerned about climate change is for credible alternatives to be adopted by our Scottish Government.

Maybe the by-election to replace Boris Johnson would not have been won by the Tories if individual testing of older vehicles or adequate affordable public transport had been in place.

In terms of replacing gas boilers, a credible affordable alternative must be presented. Air source heat pumps require a very large surface to output their heat. Underfloor heating with lots of tubing is required to heat a home given the 30-40C water air pumps are limited to producing in winter. Existing radiators are far too small and are inadequate.

The Green Party, in trying to drive change, are talking about taxing users of gas boilers – at a time when the price of electricity is artificially inflated to match the price of gas. Homeowners or landlords who understand the cost and disruption implications of the required insulation and conversion of their gas boilers to air pumps, albeit with grants part-financing the change, will understandably revolt.

The opportunity for voters to follow dangerous, populist policies like Sunak’s will only be enhanced.

There is a solution. The Green New Deal from Common Weal offers a costed, radical and credible alternative as championed by National columnists Lesley Riddoch and Joanna Cherry MP.

It involves the national control of our energy supply and distribution, the retrofitting of our homes, district heating for many of our homes and reduced energy bills for consumers.

If our Scottish Government does not have the power or finance to deliver such a scheme under devolution, then what better policy to campaign under for support for independence and to move the dial from 50% to 60%?

TONY Kime (Letters, Sep 23) asks us to accept that the Scottish Greens have had a “good influence” on SNP policies. Opinion polls, by-election results and plain common sense would all suggest the complete opposite is the case.

The green tail has been in serious danger of dragging the SNP dog down and out of government for a long time.

As is usual with Green Party supporters, he makes the rather arrogant suggestion that anyone questioning their logic – Fergus Ewing MSP in this case – does “not have any interest in the future of our youngsters”.

I rather suspect that Mr Kime has probably not devoted his life to the cause of independence and our children’s future half as much as Fergus Ewing and his family have.

No-one, including Fergus Ewing, is suggesting we ignore climate change. It is now upon us and will only get worse but the likes of the governments of China, India and the US should be the target of Mr Kime’s apparent anger.

The question of how we in Scotland can afford to heat our homes without gas, which the Green Party seeks to outlaw in a short time, has been raised a number of times both in the Scottish Parliament and even in The National’s letters pages.

No answers have been forthcoming. Stopping the exploitation of our own oil and gas will simply lead to imports of more expensive foreign oil and gas – unless of course the children

Mr Kime is apparently so concerned about are to suffer the cold of many a Scottish winter.

The less said about the Green Party minister who led the recent disastrous recycling scheme the better. The almost £100 million costs will have to be met by the Scottish taxpayer. It will not be recycled but is lost forever.

HOW wonderful to watch European women retain the Solheim Cup. How proud I am to be a European.

How I wish we were closer politically and economically. We were, I was, no longer am, and fervently wish to be again.
