The Energy Trilemma: Why the World is Turning Back to Coal
For years, the global narrative was clear: coal was a relic of the industrial past, a “dirty” fuel destined for the scrapheap of history. From the COP26 UN Climate Summit to the G7’s ambitious pledges to exit unabated coal power by 2035, the roadmap to a green future seemed set in stone. But geopolitics has a way of shattering stone.
We are currently witnessing a phenomenon known as the Energy Trilemma—the struggle to balance energy security, energy equity (affordability), and environmental sustainability. When the lights flicker or gas prices skyrocket due to conflict in the Middle East, security and affordability almost always win over sustainability.
The Asian Pivot: Prioritizing Survival Over Pledges
In Asia, the shift back to coal isn’t just about cost; it’s about national security. India and South Korea provide a masterclass in how energy vulnerability dictates policy. India, which relies on LNG imports for a significant portion of its energy needs, has found itself exposed to the volatility of the Strait of Hormuz. The result? A strategic pivot back to cheaper, domestic coal to ensure the economy doesn’t grind to a halt.
South Korea has taken an even more aggressive approach. By abolishing regulatory caps on coal-fired power plants and surging imports—particularly from Russia—Seoul is prioritizing grid stability over carbon targets. While they are simultaneously ramping up nuclear capacity to 80%, the immediate gap is being filled by the most reliable baseload power available: coal.
The “Baseload” Problem
The core issue remains the “intermittency” of renewables. Wind and solar are fantastic, but they cannot yet provide the constant, unwavering flow of electricity required by heavy industry. Until long-duration battery storage becomes commercially viable at scale, coal remains the “insurance policy” for many emerging economies.
Europe’s Industrial Identity Crisis
Even in the heart of the “Green Deal” movement, the cracks are showing. Germany and Italy are discovering that decommissioning coal plants is easy on paper, but perilous in practice. Germany’s landmark Coal Exit Law mandated a shutdown by 2038, but the reality is that the “hydrogen-ready” gas plants intended to replace them are lagging behind schedule.
When the industrial core of Europe—the factories and chemical plants that drive the GDP—faces unrealistic decommissioning targets, the government is forced to blink. We are seeing a trend where “reserve mode” coal plants are being brought back into the regular market to cushion price spikes.
Italy has gone a step further, postponing its coal phase-out deadline by over a decade. By extending the life of plants owned by utilities like Enel S.p.A, Italy is treating coal as an emergency asset. This signals a broader trend: the transition is moving from a linear sprint to a jagged crawl.
Future Trends: What Comes Next?
Looking ahead, the “all-or-nothing” approach to decarbonization is likely to be replaced by Pragmatic Diversification. Here are the trends that will define the next decade:
- The Nuclear Renaissance: As seen in South Korea, nations will likely lean harder into nuclear energy to provide carbon-free baseload power that coal currently provides.
- Strategic Coal Reserves: Similar to Strategic Petroleum Reserves, countries may maintain “dormant” coal capacity as a hedge against geopolitical shocks.
- Hyper-Localization of Energy: To avoid the “Hormuz Trap,” nations will invest more heavily in domestic energy sources, even if they are less “green” than imported LNG.
- Accelerated Storage Innovation: The resurgence of coal will ironically provide the economic incentive to fast-track solid-state batteries and green hydrogen to eliminate the need for baseload fossils.

Frequently Asked Questions
Why is coal making a comeback if it’s more polluting?
Coal is often cheaper and more readily available domestically than imported natural gas (LNG). During geopolitical crises, governments prioritize “energy security” (keeping the lights on) over “energy transition” (reducing emissions).
What is “unabated” coal power?
Unabated coal refers to coal power plants that do not use Carbon Capture and Storage (CCS) technology to trap CO2 emissions before they enter the atmosphere.
Can nuclear energy completely replace coal?
In theory, yes, because both provide “baseload” power. However, nuclear plants take a decade or more to build and require massive upfront investment, making coal a faster short-term fix during a crisis.
Is the G7 still committed to the 2035 coal exit?
While the official pledges remain, the implementation is becoming flexible. Many nations are introducing “emergency clauses” or slowing down the phase-out to protect their industrial sectors.
What do you think? Is it realistic to expect a total coal phase-out while the world is in a state of geopolitical instability, or should we accept a slower, more pragmatic transition? Let us know in the comments below or subscribe to our newsletter for weekly energy deep-dives.
