The UK is going to become home to the world's largest offshore wind farm.
The wind farm, with 341 turbines, will be built 12 miles off the coast of Kent and should be up and running in time for the 2012 Olympics.
The multi-billion pound plan has been controversial because some people think turbines are ugly, but now it's got the go ahead from the government.
Work will start in the summer and, when it's finished, the turbines should make enough energy to power 750,000 homes.
Wind turbines are a source of renewable energy which is good for the environment.
It is hoped these new turbines could help cut the UK's production of harmful gases by 80% by the year 2050.
