US Coal Surge vs Asia’s Clean Power Shift

Introduction

A recent analysis highlights a diverging global energy transition trend, where Asian economies are reducing carbon intensity, while the United States has witnessed a rise due to increased coal usage. This development has implications for global climate commitments, energy security, and decarbonisation pathways.

Analysis

East–West Divergence in Energy Transition

The article highlights a structural shift in global energy systems. Major Asian economies such as China, India, Japan and Vietnam have reduced carbon intensity of power generation, indicating cleaner electricity production. In contrast, the United States has recorded an increase in carbon intensity in 2025, making it an outlier among major economies. This divergence reflects differing policy choices, energy mix transitions, and economic conditions.

Role of Coal in Carbon Intensity Trends

The primary driver of rising carbon intensity in the United States is the ~13% increase in coal-fired power generation, which pushed emissions to a three-year high. Higher natural gas prices (around 50% increase) incentivised utilities to shift towards coal. Coal accounted for ~73% of the increase in electricity supply in the U.S., significantly impacting emission trends.In contrast, Asian countries, despite higher coal dependency, have improved efficiency and expanded renewables. India (~70%), China (~55%), Vietnam (~48%) and Japan (~27%) remain coal-reliant, yet they have managed to reduce emissions intensity through clean energy expansion.

Carbon Intensity Trends (Comparative Perspective)

China stands out for achieving continuous annual declines in carbon intensity, driven by large-scale deployment of renewable energy.

Structural Factors Influencing Trends

Several structural factors explain the divergence:

• Energy prices: High gas prices in the U.S. pushed coal usage
• Renewable expansion: Asia accelerated solar, wind deployment
• Economic slowdown: Reduced industrial demand in China and Europe limited emissions
• Energy security concerns: Countries prioritised affordability over emissions

Implications for 2026 and Beyond

The trend suggests that:

• The U.S. may continue to see rising carbon intensity due to sustained coal reliance
• Asia may witness a temporary rise in emissions intensity if industrial activity rebounds
• Global decarbonisation remains uneven and policy-dependent

The article underscores a key climate insight:

Reduction in carbon intensity is not uniform globally and can reverse due to economic and energy market shocks.

Key Concepts from Article

• Carbon Intensity: CO₂ emissions per unit of electricity (gCO₂/kWh)
• U.S. (2025): ~383.3 gCO₂/kWh (↑ from 2024)
• China (2025): ~562 gCO₂/kWh (↓ from 2019 ~670)

Conclusion

The article reflects a critical turning point in global energy transition, where Asia is advancing faster in reducing carbon intensity, while the U.S. faces a temporary reversal due to coal resurgence. It reinforces the importance of stable energy pricing, renewable expansion, and policy consistency in achieving long-term decarbonisation goals.
