According to the BBC, Wales will be getting one of the largest offshore wind farms in the world.
The 250 turbines of Gwynt y Môr offshore wind farm will be built eight miles off the coast, 10 miles away from Llandudno, Conwy.
Gwynt y Môr, combined with three other nearby wind farms, will provide enough green electricity to power the equivalent of 680,000 homes.
It has been approved by the Department of Energy and Climate Change (DECC).
The wind farm will start to produce power from 2012, subject to consent for onshore electricity works.
