The Paradox of Growing Coal Capacity

The global energy landscape is experiencing a significant paradox. Last year, the world added dozens of new coal-fired power plants. This marked the largest expansion of coal infrastructure in ten years. However, this growth in physical capacity coincided with a decrease in the actual consumption of coal. For the first time in recent history, the total amount of electricity generated by coal power plants globally declined. This shift indicates a fundamental change in how modern energy systems operate. New power plants are being constructed even as their output is increasingly replaced by other energy sources.

Christine Shearer of the Global Energy Monitor, which conducted this comprehensive analysis, highlighted this contradiction. She stated that in 2025, the world built more coal capacity but utilized it less. This paradox demonstrates that the construction of new fossil fuel infrastructure is outpacing its immediate operational necessity. The data suggests that the energy sector is preparing for future demand rather than meeting current needs.

To understand this trend, one must distinguish between capacity and generation. Capacity is a theoretical measure of how much electricity a power plant can possibly produce if it runs at full power continuously. Generation is the actual electricity produced during a specific period. Last year, global coal capacity rose by 3.5 percent. At the same time, coal generation slipped by 0.6 percent.

This decline occurred because coal is losing ground to wind and solar power. Renewables are becoming more efficient and cost-effective, displacing coal in the energy mix. This means that even though new coal plants are ready to operate, they are not needed to meet immediate energy demand. The energy grid no longer requires the continuous output of coal to function reliably. Instead, wind and solar provide the bulk of the power, leaving coal plants idle or running only during peak demand times.
