　　Even as it navigates global uncertainties and supply chain disruptions, China has made significant strides in enhancing its domestic energy security, with the energy self-sufficiency rate rising to above 80 percent.

　　This improvement in recent years is part of a larger trend of steady growth in domestic energy supply, driven by the increased production of oil and natural gas, according to a report released by China National Petroleum Corp Economics and Technology Research Institute in Beijing in January.

　　The country's total oil and gas output surpassed 400 million metric tons of oil equivalent last year, while total power generation exceeded 10 trillion kilowatt-hours, marking a 5.7 percent increase over the previous year, it said.

　　Industry experts believe domestic oil and gas output has been playing a central role in the country's energy self-sufficiency, while advancements in exploration and production technology have also boosted output, ensuring stronger energy resilience in the world's second-largest economy.

　　This growth reflects continued investments in exploration and development across both traditional and unconventional energy sources, as Chinese oil and gas companies are intensifying exploration and development efforts to boost reserves and enhance efficiency, said Lu Ruquan, head of the China National Petroleum Corp Economics and Technology Research Institute.
