FOR all those who support the Navitus Bay wind farm proposal, I wish to bring the following points: 1. On Friday, January 2 2015, a wind turbine that was 328ft tall and worth more than £2 million buckled and collapsed on a mountainside in Northern Ireland, in only medium wind speeds.

The other turbines had to be shut down for the manufacturer to investigate the cause.

2. On Monday, January 19 2015, the demand for electricity hit its highest level this winter (between 5pm and 5.30pm) according to the National Grid.

At the same time, low wind speeds meant that wind turbines were producing just 573 megawatts of power, enough to meet only 1 per cent of demand.

The analysis gives rise to concerns that, despite receiving billions of pounds in subsidies, Britain’s wind farms cannot be relied upon to keep the lights on when they are needed the most.

Gas, coal and nuclear plants supply the vast majority of the UK’s needs.

3. For those who keep harping on about climate change and so-called ‘global warming’ the vast amount of carbon found in the atmosphere is not caused by man’s activities, rather, it is derived from the ever-increasing number of active volcanoes across the globe (as I reported by letter a few years ago in this newspaper).
