New energy, also known as unconventional energy, is a variety of energy forms other than traditional energy, which are in the early stages of development and use or are being actively researched and yet to be promoted, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy and nuclear fusion energy. Climate change is a global issue facing mankind, and countries around the world are reducing greenhouse gas emissions in a global agreement. China has proposed carbon peak and carbon neutral targets in order to increase the country's independent contribution. For the implementation of the "double carbon" target and the transformation of the energy structure, electricity is the main force and new energy is the main battlefield. "The 14th Five-Year Plan is a critical period for achieving carbon peaks and promoting carbon neutrality. At present, renewable energy technologies such as photovoltaic, wind power, hydrogen, biomass and nuclear power have made great strides and have formed a certain scale throughout the country. The development and utilisation of renewable energy has provided thousands of enterprises with brand new development opportunities and brought about huge transformation challenges.
