Australia faces an exodus of 17 billion Australian dollars ($13.3 billion) in investment from its wind-farm industry because of a political deadlock, threatening to deal the country a major economic blow and kill hopes of meeting a self-imposed clean energy target.

Some 44 Australian wind-farm projects, about half of them overseas-funded, have been shelved since the new conservative government said it wanted to cut state support for the industry a year ago, with investors and operators saying they are considering either downscaling or leaving the country altogether if it succeeds.

Even Australian wind-farm companies such as Infigen and Pacific Hydro have effectively shelved their Australian operations, with Infigen saying it plans to pour all its financial muscle into the more amenable U.S. market.
