Billion pound windfarm opens

A billion pound windfarm that's been built off the coast of Norfolk has just been officially opened by the Crown Prince of Norway.

The Sheringham Shoal windfarm contains 88 turbines which, when they're all turning, will produce enough electricity to power more than 200,000 homes.

Designers say the windfarm, which has been built by Norwegian energy firms, will reduce carbon dioxide emmissions in the UK by 500,000 tonnes a year.

It could produce enough electricity to power 220 thousand homes - that's the equivalent of all the households in Cambridge, Norwich and Ipswich.
