What is new energy technology?

New energy technologies include coal-fired and magnetohydrodynamic power generation technologies.

New energy technology is the pillar of high technology, including nuclear energy technology, solar energy technology, coal burning, magnetic fluid power generation technology, geothermal energy technology, ocean energy technology and so on. Among them, nuclear energy technology and solar energy technology are the main signs of new energy technology. The development and utilization of nuclear energy and solar energy has broken the traditional energy concept with oil and coal as the main body and created a new era of energy.

Type:

Clean coal: It has become an important strategic task for China and even the whole world to adopt advanced combustion and pollution control technologies and efficient and clean coal utilization methods (such as coal gasification and liquefaction) to reduce pollutant emissions from coal combustion and improve coal utilization.

Solar energy: the sun radiates huge energy into space, and the earth receives only a tiny part of it. Due to the different geographical location, seasons and climatic conditions, the solar energy received in different places and at different times is different. The average solar energy received by the ground is roughly:

Northern Europe is about 2kw/ hour per square meter every day, and it is about 6kw/ hour per square meter in most desert areas, most tropical areas and sunny and arid areas. The solar energy used by human beings is less than 1% of the total energy consumption.

Geothermal energy: It is estimated that in most parts of the earth, the temperature rises by about 3℃ every 100 meters from the surface, and the temperature at 35 kilometers below the surface is about1100℃-1300℃, and the core temperature is even higher than 2000℃.

It is estimated that the heat transferred from the interior of the earth to the surface of the earth every year is equivalent to the heat released by burning 37 billion tons of coal. If only the total heat of underground hot water and underground steam is calculated, it is 6.5438+0.7 million times that of all coal stored on the earth.

Geothermal energy is mainly used for power generation, but there are also many ways of non-electric application. The world's first experimental power station using geothermal power was put into operation in Italy in 1964. Geothermal resources received widespread attention after the 1960s. Many countries in the world are actively studying the development and utilization of geothermal resources. Geothermal energy is mainly used for power generation, and the total installed capacity of geothermal power generation has reached several million kilowatts.

China is also rich in geothermal resources, with high-temperature geothermal resources mainly distributed in Tibet, western Yunnan and Taiwan Province Province.
