Worldwide Promotion Measures for Renewable Energy Introduction
The worldwide promotion measures for renewable energy introduction are roughly categorized into 2 groups.
RPS (RPS: Renewables Portfolio Standard) (Regulation by quantity: Obliges electric utilities to use a fixed minimum amount of renewable energy sources)
- Characteristics: It enables introduction in a step-wise manner starting from low-cost renewable energy sources and numerical figures can be set.
- Launched in the U.S., UK, Australia, Japan, etc.
- In general, introduction has made progress in RPS-adopting countries for achieving the target.
Feed in Tariff (FIT) (Regulation by price: Obliges electric utilities to purchase renewable energy sources at a fixed price). In Japan, the purchase scheme applies only to excess electricity by PV power generation.
- Feed in Tariff (FIT) is a scheme that obliges electric companies to purchase electricity generated from new energy sources, etc.
- Unlike in the RPS method, it is difficult to set targets for introduced capacity.
- Launched in Germany, Spain, Italy, etc.
- Introduction of renewable energy is in progress at a high purchasing price in FIT-adopting countries; however, movements to review the purchase price are seen in recent years.
