Two factors outside the wind business will likely encourage further strong growth this year. First, uncertainty over fuel supplies and prices, particularly with regard to gas, is growing. In a gas-fired power station, fuel cost alone is now around $36/MWh. Second, fossil fuel prices are being loaded with extra costs in global cap-and-trade markets for reducing carbon emissions. On the other hand, wind may suffer if nuclear makes a come-back. As concerns about gas rise so do nuclear's aspirations. It is issuing increasingly confident statements about its superiority as a carbon free source. In Britain, the whole question of a possible nuclear future is likely to be re-examined.
