I WOULD again like to respond to Andrew H Mackay’s incorrect assertion that “renewable technologies are adding to CO2 emissions’ (Letters, Feb 13).
National Grid, the company that operates our electricity network, recently dismissed Mr Mackay’s claims in his original letter as “spurious” to a Holyrood committee, and have reported that wind farms displace more than 99.9 per cent of the carbon which otherwise would have been emitted.
The recent increase in gas consumption Mr Mackay cites is largely down to an increase in space heating and gas displacing more polluting coal generation.
Renewables displaced 51.6 million tonnes of CO2 from the UK power sector in 2015 and, alongside innovations like storage, are playing a key role in the transition to a more modern, cleaner energy system.

ANDREW Mackay's useful letter describing the programmes to install wind turbines in Scotland as a "failed experiment" is too kind to its promoters.
Despite the advice of the first scientific adviser to the then Scottish Executive not to touch wind turbines pending the development of very greatly improved means of electricity storage, those politicians in charge stormed ahead, and still are doing so, regardless of the negligible benefits in any of the claimed advantages of wind-powered renewables.
Had these politicians organised smaller scale pilot studies before swallowing the windmill promoters' claims, the costs and terrible other damage would have been saved because their near-uselessness would have been confirmed.
As it is, the Scottish wind turbine "experiment" represents perhaps the most disgracefully ineffective use of taxpayers' money, which we can Ill afford. It ought to be ended forthwith.

Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers.

We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
