本文節(jié)選自國務院發(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《清潔能源藍皮書.國際清潔能源產業(yè)發(fā)展報告（2018）》。
各國能源政策取向不同，其關于清潔能源的概念有差異，既有按照能源使用對環(huán)境的影響程度來劃分的，也有將能源的清潔利用本身就當作清潔能源的定義。即便是前者，各國對環(huán)境的影響程度也有不同認知。??
美國清潔能源概念包括了水能、風電、太陽能、核能、地熱、生物質等，但是不包括天然氣。
歐洲清潔能源包括了水能、風電、太陽能、地熱、生物質、氫能，但是不包括天然氣、核能。
中國清潔能源感念包括了天然氣、水電、風電、太陽能和核電等。
雖然國內外對于清潔能源的定義有所差異，但都是圍繞這一目標而去的。

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..
