Abstract: While carbon taxes and other market-based instruments are widely regarded as optimal for climate mitigation, political constraints have prevented governments from using them. Instead, narrower instruments, including the feed-in tariff (FIT) for renewable electricity generation, have become popular. However, their causal effect on renewable electricity generation remains subject to uncertainty. We use instrumental variables to estimate the causal effect of FITs on renewable electricity generation in 26 industrialized countries, 1979–2005. We find that increasing the FIT by one U.S. cent (2000 constant prices) per kilowatt hour increases the percentage change in renewable electricity’s share of the total by 0.11 % points. All else constant, if a country implemented for a decade the sample mean FIT of three U.S. cents, the national share of renewable electricity would increase by 3.3 % points, which is more than the sample mean. In addition to demonstrating that the FIT is an effective way to increase renewable electricity generation, our approach lays the foundation for future studies of the causal effects of renewable energy policies.
