What are the sources of clean energy?

Clean energy includes tidal energy, wave energy, solar energy, wind energy, hydrogen energy, bioenergy and geothermal energy.

1. Tidal energy

Tidal energy is the energy contained in the periodic rise and fall of sea water. The difference in water level is expressed as potential energy and the speed of the current is expressed in kinetic energy. Both types of energy can be used and are a form of renewable energy. Because tides are the most reliable and regular among the various movements of sea water, and because they move up and down the shore, they were also the first to be recognized and used by man. Among the various uses of ocean energy is the use of tides. the energy is the most mature.

2. Wave energy

Wave energy is a specific form of ocean energye and one of the most important energy sources of ocean energy. Its development and use are important to alleviate the energy crisis. and It is very important to reduce environmental pollution. The movement of turbulent waves produces enormous energy, which is eternal and environmentally friendly. If the kinetic energy of waves and the wave energy of other water surfaces can be fully utilized, the future of global energy will be quite vast and promising.

3. Solar Energy

Solar energy refers to radiant thermal energy from the sun (see the three modes of thermal energy transmission: radiation). Its main manifestation is often called). solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters.

Since the birth of life on earth, it has mainly relied on ray energythermal energy provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method. to prepare food, such as making salt and drying salted fish.

As fossil fuels decline, solar energy has become a significant part of human energy consumption and continues to grow. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc. on earth.

IV. Wind power

Wind power is mainly used in two forms: wind power as electricity and wind power generation, among which wind power generation is the main one. Useizing wind power as energy means using wind to directly drive various mechanical devices, such as driving water pumps to lift water. The advantages of wind engines are: low investment, high efficiency, economy and durability.

5. Hydrogen energy

Hydrogen energy is the energy released by hydrogen during physical and chemical changes. Hydrogen energy is the chemical energy of hydrogen which mainly appears in the form of chemical compounds on earth. It is the most widespread substance in the universe. It constitutes 75% of the mass of the universe and is a secondary energy source. There are many ways to produce hydrogen industrially.

The most common include electrolysis of water to produce hydrogen, gasification of coal to produce hydrogen, steam catalytic conversion of heavy oil and natural gasturel to produce hydrogen, etc. However, the energy consumed by these reactions is greater than the energy produced. .

Baidu Encyclopedia - Clean Energy

1. Water flow, foam, or strong wind can be used to cool combustible objects and structures affected by thermal radiation 2; . Evacuate or use insulating materials to insulate combustible structures and objects threatened by thermal radiation; 3. At the same time, use water cannon cover and other methods to raise awareness of thermal radiation among commanders and soldiers.Protection.
