Extreme weather could disrupt China’s renewable energy boom

The wide electric Chinese grille rumbles with renewable energy than any other country, but this system also becomes weaker deficiencies caused by a wrong weather. The needs of ensuring reliable power supply could encourage the Chinese government to use coal burning plants.

The Chinese energy system is cleaning quickly, almost every month, establishes new records of wind and solar energy generation. Country Greenhouse Gas Emissions – The World Highest – Expected Soon the summit and starts down. The wind, sun and hydrochanges form half of Chinese energy creation capacity and is expected to increase almost 90% in 90% per year when the country has had Committed to obtaining “carbon neutrality”.

This confidence that grows in renewable energy also becomes increasingly weaker in the country’s power system in the face of weather changes. The wind and the sun can be completed through uninterrupted hydroelectric hydroelectric huge huge hydroelectric dam in southern China. But what about the wind and a drought of a solar drop?

Jianjian Shen In China and his colleagues at the University of Dalian and his colleagues Energy creation of energy generation on renewable innovative models would respond to years of “extreme weather”. The current and future wind blend of the country was played, the sun and hydropen would play in the smallest weather conditions seen in the past.

The future network was found to be more sensitive to weather changes today. In 2060, the year is very unfavorable, 12 percent could reduce energy generation capacity used compared to the network, creating potency scarcity. In 2030, under extreme cases, they found that the shortage of more than 400 terawatt-hour-hour power, almost 4% of the total energy demand. “That’s not a number that no one can put it,” Li Shuo Washington DC at the Asian Social Policy Institute.

In addition to being a general power, the drought specifically limited the number of hydro, the irregular wind and the solar generation. This could also lead to scarcity of power. “It is essential to supply the energy network with the proportion of stable energy sources with fewer meteorological factors, to avoid large electricity scales,” researchers wrote on their paper.

One way to help the provinces would be to move the electricity of surpluses more efficiently. Expanding the transmission infrastructure to do this, it can eliminate the risk of power in the current network and cut the risk of 2060. until the year, the researchers found. Adding tens of kilowatt to the new energy storage, also to alleviate the use of batteries or other methods, nor would it be relieved against hydroelectric drought.

The amount of additional storage must be added to obtain carbon neutrality “will be an astronomical number,” says Li Shuok.

Although these changes will be difficult, many storage is feasible because of the tremendous volume of batteries that are already produced in China, Lauri Myllyvirta Finland at the Center for Energy and Net Air Research. The country is also building 190 gigawatt hydrawatt hydrawatt, which can give Long-term energy storage Using surplus electricity by pumping the water above a dam, then releases more power when needed.

However, so far, the potential scarcity has promoted the Chinese government to build more plants to burn coal. In 2021 and 2022, for example, hydroelectric drought and heat waves increased power, they can cause serious blows, creating political pressure Continuous expansion of coal. In 2023, Creation of low-registration hydroelectric recorded spills.

President of China Xi Jinping said the potency of coal would prevail this year, but political support for the power source make a difficult opportunity. “If China suffers from another round of these passages, no more powerful shot centers should be answered,” says Li Shuok. “Coal is difficult; China loves coal”.
