What are the advantages of clean energy?

Clean energy has the following advantages: economy, environmental protection, less pollution or renewable resources.

Traditionally, clean energy refers to environmental protection energy, that is, environmental protection, less emissions and less pollution. However, this concept is not accurate enough, and it is easy to be mistaken for the classification of energy, thinking that energy is clean and unclean, thus misunderstanding the original intention of clean energy.

The accurate definition of clean energy should be: the technical system of clean, efficient and systematic application of energy. There are three meanings: first, clean energy is not a simple energy classification, but a technical system of energy utilization; Second, clean energy emphasizes both cleanliness and economy; Third, the cleanliness of clean energy means meeting certain emission standards.
