The concept of new energy

New energy is also called unconventional energy. Refers to various forms of energy other than traditional energy. Refers to the energy that has just been developed and utilized or is being actively studied and needs to be popularized, such as biomass energy, ocean energy, tidal energy, ocean thermal energy, etc.

1, biomass energy

Biomass energy is the energy contained in biomass, and it is the energy that green plants convert solar energy into chemical energy through chlorophyll and store it in biomass. Fossil energy such as coal, oil and natural gas is also transformed from biomass energy. The advantages of biomass energy are easy to burn, less pollution and low ash content; Disadvantages are low calorific value and thermal efficiency, large volume and difficult transportation.

2. Ocean energy

Ocean energy is a kind of renewable energy in the ocean, including tidal energy, mechanical energy and heat energy generated by waves. Ocean energy also involves a wider range, including sea surface wind energy, sea surface solar energy and marine biomass energy.

3. Tidal energy

Tidal energy refers to the potential energy generated in the process of high tide and low tide. The intensity of tidal energy is related to the number and drop of tidal heads. Usually, tides with a tidal drop of more than 3m have the value of productivity utilization. Tidal energy is mainly used for power generation.

4. Ocean thermal energy

Ocean thermal energy refers to the thermal energy generated by the temperature difference between the surface water body and the deep water body. In addition to power generation, ocean thermal energy can also be used for seawater desalination, air conditioning and deep-sea mineral development. China's marine thermal energy resources are mainly distributed in the South China Sea and the eastern part of Taiwan Province Province.
