India has complained to the World Trade Organization about support given to the renewable energy industry in eight U.S. states, the WTO said in a statement on Monday.<br/><br/>The complaint alleges the states of Washington, California, Montana, Massachusetts, Connecticut, Michigan, Delaware and Minnesota prop up their renewable sector with illegal subsidies and domestic content requirements – an obligation to buy local goods rather than imports.<br/><br/>By filing the complaint, India has triggered a 60-day window for the United States to settle the dispute, after which India could ask the WTO to adjudicate.
