Germany's windy northern state of Schleswig-Holstein has kicked off an action plan for climate protection which calls for wind power to supply all the state's electricity by 2020. Wind energy generation in Schleswig-Holstein can already cover 30% of the around 14 TWh of electricity consumed annually in the state. On a national basis, Germany has set itself a 30% target for renewables electricity by 2020. Under its state development plan, Schleswig-Holstein is providing zones for wind development equal to 1% of its total land area; improving incentives for replacing old turbines with new; and facilitating underground transmission cables to end protests to overhead lines and speed up the provision of wires for new wind. Schleswig-Holstein is dealing with the threat of rising sea levels, which are forecast to increase by as much as 60 centimetres by 2100 putting a quarter of the landscape in danger of flooding.
