Built by E.ON Climate & Renewables, the $1 billion farm covers 100,000 acres of land across four counties in West Texas and will be able to power more than 230,000 homes.  The company erected the 627 turbines and made deals with 300 different land owners in just two years time.

E.ON is now moving on to even bigger things — the London Array, which is set to be the largest offshore wind farm in the world with 630 MW being installed in just its first phase.

Roscoe will probably only hold the title as the world’s largest for a short amount of time as ever larger wind farm plans pop up around the world, especially in China.
