What energy includes clean energy?

What energy includes clean energy, including geothermal energy, hydropower, bioenergy, wind energy, ocean energy, hydrogen energy and solar energy.

1. Geothermal energy

Geothermal energy is a kind of clean energy that has been used relatively early. Geothermal energy is natural thermal energy extracted from the earth's crust. the baths use geothermal energy.

2. Hydraulic energy

Hydraulic energy is a common clean energy. Not only is the technology mature, it can also be recycled anywhere, but water is also present. Energy is also affected by natural conditions. The conditions are quite restrictive, so not all locations can use water energy.

3. Bioenergy

Bioenergy is the energy provided by living plants innature. The most common biogas belongs to bioenergy, and alcohol produced from plants also belongs to bioenergy. Commercial use of bioenergy is relatively difficult and the technology is not sufficiently advanced. These are some factors that limit the development of bioenergy.

4. Wind Energy

Wind energy has been widely used in many places. However, wind power is affected by wind speed and the power generated is not stable. , the conversion efficiency of wind power is also relatively low, this is a problem that needs to be solved in the current commercial application of wind power.

5. Ocean energy

Tides, waves, temperature differences, salinity gradients, ocean currents, etc. all belong to ocean energy. The economic benefits of ocean energy are not high and.the construction cost is high and some technologies are not yet unanimously recognized and constitute problems that must be resolved.

6. Hydrogen energy

Hydrogen energy is clean, non-toxic and produces no waste gas emissions. It is a clean energy source that is developing relatively quickly. Hydrogen energy is very efficient. The utilization rate is high, but hydrogen energy is difficult to store and inconvenient to transport. Today, these problems are slowly being resolved as hydrogen energy becomes a clean energy that can be commercialized.

7. Solar Energy

Solar energy is called the mother of energy. The coal, oil and other necessary chemical resources currently used are actually the stems of green plants that grow after photosynthesis. It was formed as a result of geological changes, but the direct use of solar energyire has low efficiency, high cost and poor stability.

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 seawater, and because they move up and down the shore, they are also the first to be recognized and used by humans. Among the various uses of ocean energy is the use of tides. the energy is the most mature.

2. Wave energytrice

Wave energy is a specific form of ocean energy and one of the most important energy sources of ocean energy. Its development and use are important to alleviate the energy crisis. and Reduce environmental contamination is very important. The movement of turbulent waves produces enormous, eternal and environmentally friendly energy. 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 birthe of life on earth, it relies mainly on the energy of thermal radiation 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,of which wind energy production is the main one. Using 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, consteam catalytic version of heavy oil and natural gas to produce hydrogen, etc. However, the energy consumed by these reactions is greater than the energy produced. .
