Folly of dash for electric cars

Sir, - Our politicians and so-called forward planners never seem to grasp the fact that that which appears feasible in theory does not always translate well into practice.

The latest concept, that of scrapping both diesel and petrol vehicles in favour of electric vehicles by 2040, is a prime example, and has huge implications environmentally and financially.

Currently there are some 2.5 million vehicles in Scotland, thus the mere scrappage of these will in itself impinge enormously on the environment.

More importantly, the demand for electricity will outstrip our current provision which can never be met by renewables.

Indeed, there have already been warnings that come a very harsh winter, power cuts are a real possibility.

This situation can only be addressed by expanding conventional power supplies, which will fly in the face of what is intended to be achieved.

Add this to the mass of batteries which, at the end of their short lives, will require to be decommissioned and recycled with all the inherent hazards.

Surely the correct approach is to make more efficient engines alongside electric vehicles.

In the end we may reflect upon the fact that in attempting to tackle one issue we may be creating an even greater problem. David L Thomson. 24 Laurence Park, Kinglassie.
