Energy Foundation China (EFC) was an affiliate of the Energy Foundation, a left-leaning grantmaking organization which promotes environmentalist energy sources and left-progressive environmental policies that operates in China under the oversight of the Chinese government. EFC is registered in California and has an office in Beijing. In 2020 Energy Foundation China separated from the Energy Foundation, also known as the United States Energy Foundation, whilst retaining the legacy EIN number.

The Energy Foundation was founded in 1991 when three major progressive foundations – the MacArthur Foundation, the Rockefeller Foundation, and the Pew Charitable Trusts – recruited recent Stanford University graduates Hal Harvey, Tom Strand, and Eric Heitz to start an environmental initiative. Energy Foundation China was launched in 1999 with support from the Hewlett and Packard foundations. (Source)
