China

China adopted a renewable energy target in 2006 and modified it in 2009 to the following targets:^[5]

• Renewable
  GW
  by 2020 (300 from hydro, 150 from wind, 30 from biomass, and 20 from solar PV)
• Renewable energy – 15% by 2020 (15% non-fossil fuel, which includes nuclear)

European Union

The European Union passed the

• Renewable electricity – 33% by 2020
• Renewable energy – 20% by 2020

Germany

The

• Renewable electricity – 35% by 2020 and 80% by 2050
• Renewable energy – 18% by 2020, 30% by 2030, and 60% by 2050^[8]

Japan

Based on the 1997 Act on the Promotion of New Energy Usage, 118 million KWh was targeted in 2012 (METI).^[9]

Republic of Korea

The Republic of Korea adopted the Act on the Promotion of the Development, Use, and Diffusion of New and Renewable Energy since 2012.^[10]

United Kingdom

The Renewables Obligation (RO)^[11] is designed to encourage generation of electricity from eligible renewable sources in the United Kingdom. It was introduced in England and Wales and in a different form (the Renewables Obligation (Scotland)) in Scotland in April 2002 and in Northern Ireland in April 2005, replacing the Non-Fossil Fuel Obligation which operated from 1990.^[12]

The RO places an obligation on licensed electricity suppliers in the United Kingdom to source an increasing proportion of electricity from renewable sources, similar to a renewable portfolio standard. In 2010/11 it is 11.1% (4.0% in Northern Ireland). This figure was initially set at 3% for the period 2002/03 and under current^[when?] political commitments rose to 15.4% (6.3% in Northern Ireland) by the period 2015/16 and then it runs until 2037 (2033 in Northern Ireland). The extension of the scheme from 2027 to 2037 was declared on 1 April 2010 and is detailed in the National Renewable Energy Action Plan.^[13] Since its introduction the RO has more than tripled the level of eligible renewable electricity generation (from 1.8%^{[citation needed]} of total UK supply to 7.0% in 2010^[14]).

United States

The Public Utility Regulatory Policies Act is a law, passed in 1978 by the United States Congress as part of the National Energy Act. It was meant to promote^{[clarification needed]} greater use of renewable energy, mostly through feed-in tariffs, but contains little language declaring explicit renewable energy objectives or quotas.

In 2009, the US Congress considered Federal level RPS requirements. The American Clean Energy and Security Act reported out of committee in July by the Senate Committee on Energy & Natural Resources includes a Renewable Electricity Standard that called for 3% of U.S. electrical generation to come from non-hydro renewables by 2013, but the full Senate did not pass the bill.^[15]

Different state RPS programs issue a different number of Renewable Energy Credits depending on the generation technology; for example, solar generation counts for twice as much as other renewable sources in Michigan and Virginia.^[16]

The Lawrence Berkeley National Laboratory claims that RPS requirements were responsible for 60% of the total increase in American renewable electricity generation since the year 2000. However, the LBNL also reports that RPSs' role has been declining in recent years from 71% of the annual American renewables builds in the year 2013 to 46% just two years later, in 2015.^[17]
