Law Concerning Special Measures for Promotion of New Energy Use (Special Measures Law for Promoting the Use of New Energy) (Law No.37 of 1997)
Based on this Law, a fundament policy to provide for basic matters concerning measures for each area that the public, utilities and governments should consider was determined in September 1997. The amendment added 'New Energy use, etc.' to Article 1 of the Act. Then, Biomass Energy and Cool Energy could be added. In April 2008, the definition of 'New Energy' was changed and became almost equivalent to renewable energy, but large-size hydropower generation and geothermal power are excluded.
