What is new energy?

New energy (NE): also known as unconventional energy. Refers to various forms of energy other than traditional energy. Refers to the energy that has just been developed or actively studied and needs to be popularized, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, nuclear fusion energy and so on.

With the progress of technology and the establishment of the concept of sustainable development, the industrial and domestic organic wastes that used to be regarded as garbage have been re-recognized, and have been deeply studied, developed and utilized as a material for the utilization of energy resources. Therefore, the resource utilization of waste can also be regarded as a form of new energy technology.

The renewable energy utilization technology has made great progress in the world and formed a certain scale. Biomass energy, solar energy, wind energy, hydropower and geothermal energy utilization technologies have been applied.

The proportion of renewable energy in primary energy is generally low, on the one hand, it is related to the importance and policies of various countries, on the other hand, it is related to the high technical cost of renewable energy, especially solar energy, biomass energy and wind energy with high technical content.

According to IEA's forecast, the cost of renewable energy generation will be greatly reduced in the next 30 years, thus increasing its competitiveness. The cost of renewable energy utilization is related to many factors, so the result of cost prediction is uncertain. However, these forecast results show that the technical cost of renewable energy utilization will decrease.
