本文節(jié)選自國(guó)務(wù)院發(fā)展研究中心洪濤先生所著《“清潔能源” 定義和范圍研究》，已作為“前言”發(fā)表于《清潔能源藍(lán)皮書(shū).國(guó)際清潔能源產(chǎn)業(yè)發(fā)展報(bào)告（2018）》。
各國(guó)能源政策取向不同，其關(guān)于清潔能源的概念有差異，既有按照能源使用對(duì)環(huán)境的影響程度來(lái)劃分的，也有將能源的清潔利用本身就當(dāng)作清潔能源的定義。即便是前者，各國(guó)對(duì)環(huán)境的影響程度也有不同認(rèn)知。??
美國(guó)清潔能源概念包括了水能、風(fēng)電、太陽(yáng)能、核能、地?zé)?、生物質(zhì)等，但是不包括天然氣。
歐洲清潔能源包括了水能、風(fēng)電、太陽(yáng)能、地?zé)?、生物質(zhì)、氫能，但是不包括天然氣、核能。
中國(guó)清潔能源感念包括了天然氣、水電、風(fēng)電、太陽(yáng)能和核電等。
雖然國(guó)內(nèi)外對(duì)于清潔能源的定義有所差異，但都是圍繞這一目標(biāo)而去的。

What’s clean energy?
The comments below are?excerpted from the article by Hong Tao who works in Development Research Center of The State Council.
The definition of clean energy varies in different countries and circumstances.
One theory is by the degree of its impact to the environment, and the other one focuses on the clean use of energy. ?
Clean energy includes hydropower, wind power, solar energy, nuclear energy, geothermal energy, biomass, etc. in U.S., but natural gas is not included.
While in Europe, it includes hydropower, wind power, solar energy, geothermal energy, biomass, hydrogen energy, but natural gas and nuclear are not included.
In China, both natural gas and nuclear are clean energy, together with hydro power, wind, solar etc..
