The proportion of energy used for power generation, after a rapid increase in the early stage, has recently entered a phase of stable development, with developed countries generally higher than developing countries. After experiencing a rapid growth phase, the proportion of energy used for power generation in developed countries generally entered a stable phase in the 1980s and 1990s; in recent years, affected by the shale gas revolution, economic crises, and other factors, there have been slight fluctuations in the proportion of energy used for power generation in some developed countries. The proportion of energy used for power generation in developing countries has been continuously increasing, especially in BRICS countries including China, where rapid economic and social development has driven the electrification level on the energy production side to quickly catch up with the level of OECD countries. The proportion of terminal electricity consumption* maintains a "steady improvement" trend, with developed countries seeing slower growth and emerging market countries experiencing rapid improvement. The slowdown in the overall electrification level improvement in developed countries is mostly influenced by factors such as continuous industrial structure adjustment and enhanced competitiveness of alternative energy sources. Developed countries in the late stage of industrialization generally see their terminal electricity consumption proportion fluctuate within the range of 20% to 25%. Driven by the industrialization process, developing countries have seen a rapid increase in the proportion of terminal electricity consumption, becoming a steady improvement in the electrification level on the terminal consumption side.
