Abstract Financial incentives are important for overcoming certain market barriers to improved energy efficiency and for the adoption of energy efficient technologies. Financial incentives are mainly focused on the introduction of specific technologies, rather than behavioural change. While the declared goal of financial support schemes very often is to save energy or reduce harmful emissions rather than to foster new technologies per se, it is often encountered that such financial support for energy efficient technologies may not ensure real energy savings due to the rebound effect and various market barriers. In the area of renewable energies it is common for financial support to be given to power producers for the verified production of renewable electricity, in the form of a guaranteed financial incentive (feed-in tariff). In the energy efficiency policy research little attention has been paid to the possible use of a “feed-in tariff” in the form of a financial incentive based on the kWh saved by the end-user. This paper discusses the possible setup of a feed-in tariff designed to reward energy savings.
