The Way Forward: Global Wind Capacity Up 20% In 2012

Wind power expanded by almost 20% in 2012 round the world to reach a new peak of 282 gigawatts (GW) of total installed capacity, while solar power reached more than 100GW, having more than doubled in two years. The UK is by far the world leader in offshore wind deployment, installing 0.85MW in 2012 to bring the total so far to 3GW.
