New energy refers to renewable and clean energy, which corresponds to traditional energy sources such as coal, oil, and natural gas. The following are some common types of new energy:

1. Solar energy: Utilizing the radiant energy of sunlight to convert into electrical or thermal energy. Solar panels can directly convert sunlight into electricity, while solar thermal systems can use sunlight to provide hot water and heating.

2. Wind energy: Transforming the power of wind into electrical energy. A wind turbine drives the generator to generate electricity by rotating its blades.

3. Hydraulic energy: Transforming the kinetic energy of water flow or the height difference of water level into electrical energy. Hydroelectric power uses water flow to drive turbines, which generate electricity through generators.

4. Biomass energy: Utilizing biomass materials (such as wood, crop waste, etc.) for combustion, fermentation, or chemical reactions to convert into thermal energy or biofuels.

5. Geothermal energy: Utilizing the thermal energy stored in the Earth's crust to generate electricity or provide heating and cooling. Geothermal power generation utilizes geothermal steam to drive turbines for power generation.

These new energy sources have the characteristics of green, clean, and renewable, which can reduce dependence on traditional fossil fuels, reduce environmental pollution, and greenhouse gas emissions. With the continuous progress of technology and the reduction of costs, the application of new energy in the energy field is becoming increasingly widespread, which is of great significance for achieving sustainable development and mitigating climate change.
