Overview: 

 New and renewable sources of energy (English abbreviation: NRSE) is relative to traditional energy sources such as coal, oil and natural gas. It is also known as unconventional energy and refers to various forms of energy other than traditional energy. It refers to the energy that has just begun to be developed and utilized or is being actively researched and promoted. Including solar energy, geothermal energy, wind energy, ocean energy, biomass energy and nuclear fusion energy, etc., with green and low-carbon, no risk of resource depletion, falling energy prices and other characteristics, it is the key area of energy development in the future. 

 Since the 1950s, countries around the world have begun to study new energy, and have achieved certain results in wind power, solar photovoltaics and photothermal power, biomass power generation, tidal utilization, etc. By the 1980s, many countries had listed it as a conventional energy source. In the 21st century, more and more attention is paid to the development of new energy based on wind power and solar energy.
