Energy, being the driving force behind human civilization, is derived from various resources that can be converted into usable forms such as thermal, electrical, light, mechanical, and chemical energy. Clean energy, also known as green energy, refers to energy sources that produce minimal or no pollution, and can be directly utilized for production and daily life, which includes nuclear energy and renewable energy sources such as hydropower, wind energy, solar energy, and tidal energy. The primary objective of utilizing clean energy is to mitigate the environmental impact of human activities while providing economically viable energy solutions. Clean energy is not only environmentally friendly with low carbon emissions and minimal pollution, but also plays a pivotal role in driving the green and low-carbon transformation of the economy and society. The development of clean energy is the cornerstone of the fourth Industrial Revolution, and is indispensable for the advancement of human civilization. Promoting clean energy is not only a global consensus for addressing climate change but also a crucial means of strengthening ecological civilization.
