At the 2022 World Clean Energy Equipment Conference held on August 27, Liu Hanyuan, chairman of the Board of Directors of Tongwei Group, could give a keynote speech on renewable energy.

"Renewable energy is easier and cheaper than expected." Liu Hanyuan said. In the process of achieving the "double carbon" goal, renewable energy represented by photovoltaic and wind energy is the main force of them. In fact, 100%renewable energy is easier and cheaper than expected.

Over the past 10 years, the cost of photovoltaic power generation has decreased by more than 90%, which has become the world's most economical way of power generation. The cost of photovoltaic power generation in my country has generally dropped to 0.3 yuan / kWh. It is expected that during the "Fourteenth Five -Year Plan" period, it will be further reduced to less than 0.25 yuan, which is lower than most coal power. If you consider ecological costs, the advantages of photovoltaic power generation will be more obvious.

From the perspective of consumption, transportation oil accounts for about 70%of my country's crude oil consumption each year, and fuel vehicles per 100 kilometers of oil are more than 5 times that of electric vehicles per 100 kilometers. Judging from the equivalent efficiency of the output, the electricity price of the consumer is less than 1/5 of the oil price.

From the perspective of the carbon reduction effect, the production of 250GW photovoltaic system requires about 43 million tons of carbon dioxide, which means that every ton of carbon emissions produced by the manufacturing photovoltaic system will reduce carbon emissions of more than 20 tons every year after the system is generated. In the entire life cycle, the entire life cycle will be It will reduce carbon emissions of more than 500 tons.

From the perspective of energy investment intensity, the entire process of 1,000 watt photovoltaic power generation systems requires about 300 kWh, and the average of about 1,500 kWh can be generated by 1,000 watt systems per year. It can be recovered in the second half of the year, and the system can run stably for more than 25 years. The electricity returned by the entire life cycle is more than 50 times that of investment.

As costs continue to decrease, the large -scale application of energy storage will also provide solid guarantees for renewable energy. Among them, pumping energy storage is the most mature and most large -scale development conditions at present. At present, the cost is about 0.2 yuan to 0.25 yuan per kilowatt -hour.

From the perspective of total global volume, places where 100 meters to 400 meters or even 600 meters to 800 meters can be constructed, and the energy that can be stored can be stored more than 100 times the energy storage of renewable energy in the world.

Liu Hanyuan believes that it should be concentrated in the construction of a large -scale construction of water -pumping storage projects during the "14th Five -Year Plan" and "Fifteenth Five -Year Plan" period, which is basically completed in about 10 years to provide a solid foundation for the transformation of the entire energy.
