Natural gas, wind energy, tidal energy, hydrogen energy, nuclear energy, solar energy, etc. are low-carbon energy sources.
1. Natural gas
Natural gas refers to all gases occurring naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere and lithosphere (including gas from oil fields, gas field gas, mud volcano gas, coalbed methane and biologically generated gas, etc.).
2. Wind energy
Wind energy is the kinetic energy generated by air flow. A converted form of solar energy. The total reserves of wind resources are very huge, and the technically developable energy in one year is approximately 5.3 x 10^13 kilowatt hours. Wind energy is a renewable and clean energy with large reserves and wide distribution. However, its energy density isweak (only 1/800 of the energy of water) and unstable. Under certain technical conditions, wind energy can be developed and used as an important energy source. Wind energy utilization is a comprehensive engineering technology that converts the kinetic energy of wind into mechanical, electrical and thermal energy through wind turbines.
3. Tidal energy
Tidal energy is the energy contained in the periodic rise and fall of sea water. The difference in water level is expressed in 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 variousits uses of ocean energy, the use of tides. the energy is the most mature.
4. Hydrogen energy
Hydrogen appears mainly in the form of chemical compounds on earth. It is the most widespread substance in the universe. It makes up 75% of the mass of the universe. the universe and is the second secondary energy. Hydrogen energy is likely to become an important energy source on the global energy scene in the 21st century. Hydrogen production, storage, transportation and application technologies will also receive great attention in the 21st century. Hydrogen has the characteristics of high combustion calorific value, which is 3 times that of gasoline, 3.9 times that of alcohol, and 4.5 times that of coke. The product of hydrogen combustion is water, which is the cleanest energy source in the world. Abundant resources and sustainable development.
5. Solar energy
TheSolar energy is a renewable energy source. It refers to the energy of thermal radiation from the sun and its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters. 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.
