Energy is an important material foundation necessary for the development of the national economy and people’s living standards. It is also the basic material guarantee necessary for human production and life. Conventional fossil energy represented by coal, oil, and natural gas will eventually be exhausted. At the same time, due to extensive use These fossil fuels cause a series of environmental problems and restrict the sustainable development of society. In the long run, the production and consumption of energy and its impact on the environment should meet the requirements of sustainable development, otherwise it will threaten the survival and development of human beings. But at present, countries in the world basically rely on non-renewable energy sources such as oil and natural gas. Research and use of sustainable or renewable alternative energy sources has always been the direction of people’s efforts.
The research, development and utilization of wind energy, biomass energy, solar energy, geothermal energy, ocean energy and other new energy sources are of great significance to the optimization of energy structure, meeting diversified energy demand and sustainable development strategies.
With the increase in energy supply, human production activities have developed rapidly. Energy, as an important foundation for economic development and the improvement of people’s living standards, has applications in all areas of daily life.
- Energy and modern industry
There are three material conditions required for modern industrial production: ① raw materials and materials; ② energy; ③ machinery and equipment. Among them, energy is crucial. If there is no sufficient energy supply as a guarantee, the production machinery and equipment will stop operating.
- Energy and modern transportation
Modern transportation uses a powerful energy industry as the basis for the operation of transportation. Energy plays an important role in the construction of national defense, and the modernization of national defense must rely on a developed energy industry
- Energy and modern agriculture
Modern agricultural production is inseparable from the supply of energy, and it needs to consume energy directly or indirectly.
With the development of agricultural mechanization and electric vaporization, the demand for energy in agricultural production will increase day by day, and energy will play a decisive role in the development of agricultural production.
In addition, people’s daily life and public utilities also consume a lot of energy. With the improvement of people’s living standards, the use of gas will continue to increase, household appliances will develop rapidly, and the role of energy in people’s lives and public utilities will become more and more important.
The most widely used energy sources in contemporary society are coal, oil, natural gas, and water power. However, the reserves of oil and natural gas are limited and non-renewable. In order to ensure large-scale energy supply, countries around the world are actively taking measures to vigorously develop wind energy, New energy technologies such as solar energy, biomass energy, geothermal energy, ocean energy, and nuclear fusion energy strive to gradually transition the current conventional energy system based on fossil energy to a durable, diversified and renewable new energy system .
Entering the era of knowledge economy in the 21st century, we should take the development and utilization of new energy technologies as an important content and an important technical pillar of the new technological revolution with information technology as the core, attach great importance to it, and vigorously develop.
