What are the forms of clean energy introduced by clean energy industry?

1. Clean energy in the traditional sense refers to energy that is environmentally friendly, 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.

Renewable energy refers to energy with renewable raw materials, such as hydropower, wind power, solar energy, biomass energy (biogas), geothermal energy (including ground source and water source), tidal energy and so on. There is no possibility of energy exhaustion in renewable energy. Therefore, the development and utilization of renewable energy has been paid more and more attention by many countries, especially those with energy shortage.

2065438+On September 20, 2009, Li Fulong, director of the Development Planning Department of the National Energy Administration, said that he was studying the energy development plan during the Tenth Five-Year Plan period and would continue to expand the development of clean energy.

2. Clean energy and its meaning include two aspects:

(1) Renewable energy.

After eating, it can be recycled and supplemented, and no or little pollutants are produced. Such as solar energy, wind energy, bioenergy, hydro energy, geothermal energy, hydrogen energy, etc. China is an international clean energy giant and the birthplace of the world's largest solar energy, wind energy and environmental technology companies.

(2) Non-renewable energy.

Minimize the pollution to the ecological environment in the process of production and consumption, including the use of low-pollution fossil energy (such as natural gas) and fossil energy treated by clean energy technology, such as clean coal and clean oil.

Although nuclear energy belongs to clean energy, it consumes uranium fuel, not renewable energy, and the investment is high. Moreover, almost all countries, including those with the most advanced technology and management, cannot guarantee the absolute safety of nuclear power plants. Chernobyl accident in the former Soviet Union, Three Mile Island accident in the United States and Fukushima nuclear accident in Japan had great influence. Nuclear power plants, especially the main targets of war or terrorist attacks, may have serious consequences after being attacked. Therefore, developed countries are slowly building nuclear power plants, and Germany is also preparing to gradually shut them down.

Renewable energy is the most ideal energy, which is not affected by energy shortage, but also by natural conditions, such as the need for hydropower, wind energy and solar energy resources. The most important thing is that the investment and maintenance costs are high and the efficiency is low, so the cost of power generation is high. Now many scientists are actively looking for ways to improve the utilization efficiency of renewable energy. I believe that with the shortage of earth resources, renewable energy will play an increasingly important role.
