The issue of energy has become one of the hottest topics in the field of exam chemistry, are summarized as follows: First, to examine the chemical classification of energy samples 1 energy is an indispensable resource in this world. The following does not belong to “green energy” is () ( A) Hydrogen energy (B) Alcohol (C) Coal (D) Solar energy analysis: “Green energy ” refers to the energy that does not pollute the environment or is renewable.Hydrogen energy is rich in resources, Alcohol burns in the air to generate water and carbon dioxide. It is often used as a fuel for internal combustion engines and is a green renewable energy. Coal contains more impurities and can produce pollutants when it burns
