Overview of new energy:
The analysis shows that the energy consumption structure of China has not changed significantly since 200 1 year. Petrochemical energy consumption, especially coal consumption, has always been in a dominant position in primary energy consumption, accounting for more than 90% and 60% respectively.
2. For the new energy industry, it is considered that this has provided the gospel. A comprehensive observation of the China stock market industry also illustrates this point. The price of green energy stocks in China soared, and more idle funds were invested in new energy and environmental protection industries. At the same time, China will surpass Europe and become the largest alternative energy growth market in the world. In this context, the new energy industry should seize this opportunity, actively develop wind power and solar energy, and increase the proportion of new energy.
3. It is estimated that the solar energy radiated to the earth every year is 65.438+0.78 billion kilowatts, of which 5-6.5438+0.000 billion kilowatt hours can be developed and utilized. However, due to the scattered distribution, it can be used very little. Geothermal energy resources refer to the total heat content of rocks and water bodies within 5000 meters below land. Among them, the high-temperature geothermal energy resources within 3 kilometers of the global land and above 150℃ are10.4 million tons of standard coal, and some countries have started commercial development and utilization. The world's wind energy potential is about 350 billion kilowatts, and it is difficult to use it economically because of the intermittent dispersion of wind power. If the technology of energy transmission and storage is greatly improved in the future, the utilization of wind power will increase. Ocean energy includes tidal energy, wave energy, seawater temperature difference energy and so on, and its theoretical reserves are very considerable. Limited by the technical level, it is still in the small-scale research stage. At present, because the utilization technology of new energy is still immature, it only accounts for a small part of the total energy needed in the world, and its future development prospects are great.
