The Law Concerning Special Measures for Promotion of New Energy Use (New Energy Law) was enacted in April 1997 to accelerate the advancement of the introduction of New Energy. This law, while clarifying the role of each area for the overall advancement of New Energy usage, provided for financial support measures for utilities that use new energy. Also in September 1997, based on this law, a fundamental policy to provide for basic matters concerning measures for each area that the public, utilities, and governments should consider was determined. In January 2002, an amendment was made to Article 1 of the Act for the "New Energy use, etc." section of this law so that Biomass Energy and Cool Energy could be added. In April 2008, the definition of "New Energy" was been changed, and made almost equivalent to that of renewable energy, but large-size hydro power generation and geothermal power are excluded.
