Shell backed out of its commitment to provide the financing for one third of the world’s largest offshore wind farm off the Kent coast.

The project has reasonable economics, and private individuals could benefit from 40% tax relief by putting shareholdings into pension plans.

Simple calculations suggest that this change may add about 15-25% to UK electricity bills. Offshore wind is more expensive to construct and operate than onshore wind farms. The announcement may suggest that the government believes that offshore wind can be pushed through but that onshore farms are likely to be successfully opposed. The big push for offshore wind seems to mean that the government is losing faith in nuclear.

One of the few co-operatively owned wind farms in the country has almost finished raising its funds. Investors have put up £3m to buy two existing turbines in the Fens. Locally owned wind farms should be encouraged as a cost effective means of cutting emissions.
