Which one is not the fossil energy we are currently using?

Biomass energy is not the fossil energy we use at present.

Fossil energy refers to carbon-containing energy represented by oil, natural gas and coal, which can actually be regarded as a kind of chemical energy. Its energy utilization is mainly based on the chemical exothermic reaction of carbon oxidation to CO2 (including oxygen oxidation to water). Some reactions of carbon elements involved are basic chemical reactions existing in nature, which are related to the whole process of life origin, life generation, development and extinction, and also to the whole process of formation, utilization and consumption of fossil energy.

Fossil energy is a kind of natural hydrocarbon or its derivatives, including coal, oil and natural gas, which belongs to non-renewable primary energy. Fossil energy is the most important energy consumed in the world, accounting for 87.9% of global energy consumption in 2006. However, with the continuous exploitation of human beings, the exhaustion of fossil energy is inevitable, and most of the fossil energy will be exhausted in this century. Developing cleaner renewable energy is the future development direction.

Harm of fossil energy

1, global climate change. Carbon in fuel is converted into carbon dioxide and enters the atmosphere, which increases the concentration of carbon dioxide in the atmosphere, thus leading to the greenhouse effect, changing the global climate and endangering the ecological balance.

2. Thermal pollution. The "waste heat" left by power generation in thermal power plants is discharged into rivers, lakes, atmosphere or oceans, which will cause thermal pollution in most cases.
