Sheep graze in front of wind turbines that are part of the Infigen Energy's Capital Windfarm located on the hills surrounding Lake George, near the Australian capital city of Canberra, Australia, July 17, 2015. Australian Prime Minister Tony Abbott's hostility to "visually awful" wind farms has sent a chill through the industry and could jeopardize the country's biggest renewable energy project, a $2 billion-plus wind and solar plant in the country's north. In an early sign that a new Federal policy could curtail major renewable projects, the company planning to build the 1,200-megawatt plant said it may struggle to attract financing after the government blocked state support for wind farms.
