The world’s largest renewables project, the 15GW Asian Renewable Energy Hub (AREH) in Western Australia, has passed a significant hurdle by receiving a green light from the state's Environmental Protection Agency (EPA).

This is no mean feat as the 6,500sq km wind/solar project — which would be larger than the US state of West Virginia — requires the clearing of almost 120sq km of native vegetation in the Pilbara region of Western Australia, and the installation of four subsea cables running through a protected marine park with several endangered species.
