Traditional energy and new energy

New energy resources are abundant, generally renewable, and can be used by human beings forever; For example, it is estimated that the exploitable wind energy resources on land are 253 GW, but only 0.57 GW has been developed and utilized by 2003. It is predicted that by 20 10, the available wind energy resources will reach 4GW and 20GW by 2020.

Traditional energy is primary energy. Also known as traditional energy. Such as coal, oil, natural gas and water, are the main energy sources to promote social progress and civilization.

2. Different energy security:

There are many uncertainties in international trade. The international energy price may tend to be stable with the improvement of the international peaceful environment, but it may also fluctuate with the turmoil of the international situation. In the future, the instability of the international oil market and the fluctuation of oil prices will seriously affect China's oil supply and have a great impact on the economy and society.

Vigorously developing renewable energy can relatively reduce the proportion of fossil energy in China's energy demand and its dependence on imported energy, and improve China's energy and economic security.

3. Different routines:

Conventional energy refers to energy that is technically mature and has been used on a large scale, while new energy usually refers to energy that has not been used on a large scale and is being actively developed. Therefore, coal, oil, natural gas and large and medium-sized hydropower are regarded as conventional energy sources, while solar energy, wind energy, modern biomass energy, geothermal energy, ocean energy and hydrogen energy are regarded as new energy sources.
