KEITH MacLeod waxes lyrical in praise of electric vehicles but misses several points (Letters, September 18).
At the moment no vehicle is emission free: the electricity to charge the batteries must be generated somewhere, often at the cost of some pretty serious emissions.
Those who boast of lengthy journeys by electric car with minimal delay at fast charging points need to explain what length these delays would be if there were, say, 50 vehicles, or perhaps 100 or so, requiring power at the same time.
It would make more sense to opt for hydrogen-powered engines. So what if they are only 25 per cent efficient? What would that matter if the pollution-free gas was produced with cheap, renewable electricity?
As for a zero emissions trip to Hamburg, are we to assume the ferry boat had sails?

Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
Callum Baird, Editor of The National
