This brochure explains Feed-In Tariff (FIT) laws. The big challenge for the renewable energy industry has been to make the cost of clean energy competitive with heavily-subsidized conventional energy. Householders or energy companies who want to install wind turbines or solar panels are faced with lengthy pay-back times and are forced to make a choice based on ethics rather than economics. The Feed-In Tariff (FIT) has proven to be the most effective policy instrument in overcoming these barriers. This simple, low-cost mechanism has turned several European countries into world leaders in the renewables sector.
