Wind farms are a sick joke
WIND turbines as sources of energy are wind speed-dependent electricity generators typifying the wastefulness of the UK’s futile attempts to avert the world’s risks of dangerous climate changes.
As proportions of our used electricity supplies, wind turbines contribute percentages ranging between single figures and about a third. They are always dependent on variable wind strength and on fossil fuel back-up.
Because of inability to store useful amounts of electricity, Sir David MacKay, Professor of Engineering at Cambridge University and government scientific adviser, warned the politicians not to touch them, pending vast improvements in battery storage. That has not proved possible.
No pilot studies were done before their adoption so as to evaluate wind turbines’ usefulness and drawbacks. Professor MacKay’s advice was ignored. Since then, some 11,000 UK wind turbines have been installed.
Costs are about £20,000 for each windmill’s structure alone. They are manufactured mainly in China.
Including the additional outlays for installation, servicing and maintenance the costs amount to, it is said, a total of up to £250,000 for each. Their lifespan is only about 15-20 years.
Damage to land, sea, people and avian wildlife is incalculable.
All in all, this is a scandalous waste, especially recalling that they are not even green when the greenhouse gases emitted from manufacturing, transport and installation are included.
The UK’s carbon dioxide output is negligible at less than 1.5 per cent of the planet’s total. They still need petroleum products for backup and lubrication.
Their installations are ongoing, with no end in sight. It is no wonder that the authorities of the eastern nations, China, India and many more non-compliant in decarbonisation are laughing at us.
