ANOTHER side of the wind turbine saga is the CO2 reduction.
One correspondent said payback of three to six months – 30 years is a more accurate figure, the three to six months is another of the Navitus spin manipulations.
The bauxite is mined in Central/East Russia (fossil fuel used), crudely smelted (Chernobyl type nuclear power), transported thousands of miles across Russia (diesel train), offloaded at St Petersburg docks, transferred to diesel-powered ships to transport to Denmark, refined into useable quality aluminium and then cast into wind turbine parts, transported again by diesel ships to the UK.
The copper cabling, mined in Nigeria refined and transported to the UK (more fossil fuel).
The infra structure for the wind turbines and connection to the National Grid through the New Forest (pylons or buried cable to Mannington near Verwood) is another reason the first generation of turbines do not show a reduction in the world’s CO2.
The maintenance of offshore turbines is also very costly to the world’s CO2 as a number of special maintenance ships have to be built for this purpose.
The damage to the seabed and New Forest will be considerable.
M Fry’s very interesting and well-researched letter about Germany’s problems with wind turbine output is another good reason to forget Navitus proposed exploitation of the English Channel.
