When the Netherlands built its first sea-based wind turbines in 2006, they were seen as symbols of a greener future.

Towering over the waves of the North Sea like an army of giants, blades whipping through the wind, the turbines were the country's best hope to curb carbon emissions and meet growing demand for electricity.

The 36 turbines -- each one the height of a 30-storey building -- produce enough electricity to meet the needs of more than 100,000 households each year.

But five years later the green future looks a long way off. Faced with the need to cut its budget deficit, the Dutch government says offshore wind power is too expensive and that it cannot afford to subsidize the entire cost of 18 cents per kilowatt hour -- some 4.5 billion euros last year.

The government now plans to transfer the financial burden to households and industrial consumers in order to secure the funds for wind power and try to attract private sector investment.
