I AM not sure how Tony Hamilton and Agenda 21 can be so certain that the “visual impact (of Navitus Wind farm) is not a significant problem ” (Letters, September 25).

As far as I know, no plans for the project are yet available.

No decision has been made on whether they will be 6 or 9 MGWt wind turbines, something which will affect the height. No planning decisions have been made as to whether they will be at the front of the box or further out.

What can be said is that these migrating bird chompers will be an intrusion on our beaches and wonderful coastline.

I could be persuaded that the intrusion might be worth it if it were the only way to provide essential power to Poole homes and businesses at a really competitive rate that would massively stimulate out economy. The facts are entirely against this.

Going back to adapting medieval technologies is never a good idea.

It is like abandoning gas and nuclear production of energy and relying once more on charcoal burning. Windmill production fluctuates wildly, from 90 per cent to zero within a few days.

This means not only having to use coal or gas power stations running at loss-making, back-up mode, but the fluctuations can destabilise the Grid causing blackouts.

Economic studies have shown that wind energy is up to 10 times more costly to produce than gas or nuclear and can only attract developers by forcing power companies to buy the electricity at 100 per cent mark-up for onshore and 200 per cent mark-up for offshore wind. ENECO/EDF will be farming subsidies not wind, paid for by each one of us in extra charges on our electricity bills.

James Lovelock, the author of the Gaia theory, says, “renewables are a waste of space”. This is true, but they are also a scandalously poor use of money and resources in a debt crisis. Navitus will damage our incomes, our health, our coastline and our property.
