I’ll explain why coal still matters, show fresh cost comparisons that favor existing coal, note how intermittent wind and solar add hidden expenses, and point out that the global energy mix remains dominated by fossil fuels despite decades of renewable hype.
Talk of coal’s wholesale collapse was premature and politically driven. For years policy choices and regulatory pressure pushed utilities to retire coal, but economics and reliability tell a different story. Consumers have felt the impact as rates climbed and grid outages increased where baseload capacity was removed.
Recent work looking directly at plant-level data underlines this reality. Energy Bad Boys analyzed 82 U.S. coal plants using Federal Energy Regulatory Commission data and found that “[o]n average, existing coal plants operate at $45.57 per megawatt-hour (MWh).” That figure is striking when you compare it to other technologies on the grid today.
Industrial wind, on average, runs at $59.78/MWh, while industrial solar clocks in around $102.40/MWh for existing facilities. New industrial wind is even less competitive at $62.09/MWh, and new solar sits near $74.55/MWh by EIA estimates. Those numbers show that, pound for pound, existing coal often delivers cheaper electricity than wind or solar.
What those price tags don’t capture is the cost of making intermittent power dependable. Grid operators need firming solutions—battery storage, hydro pumping, or gas-fired backup—to cover wind and solar’s variability. Had the comparisons included these added firming costs, the gap between cheap coal and pricier renewables would be wider still.
Transmission is another hidden bill. Wind and solar are often built far from demand centers, requiring long-distance lines and expensive grid upgrades. Those buildouts add capital expense and operational complexity that aren’t always reflected in headline levelized cost numbers.
There’s also a scale issue people miss when they celebrate growth percentages for renewables. A small uptick in coal, oil, or gas output still represents a huge absolute increase in energy compared with a much larger percentage gain from a tiny renewable base. That math keeps fossil fuels central to the global supply mix regardless of media narratives.
Year-after-year statistical reviews from major energy institutes show fossil fuels still account for the vast majority of worldwide energy. Despite subsidies, mandates, and repeated claims of an energy transition, the world remains heavily reliant on coal, oil, and gas. Political pressure can change which plants close, but it cannot instantly rewrite the physics and economics of large-scale power systems.
Where policymakers have forced rapid retirement of baseload generation, electricity prices have tended to rise faster and reliability has suffered. That outcome is predictable: intermittent resources need firming capacity and redundant infrastructure to keep lights on during lulls, and customers ultimately bear those costs. The utility executives who favored renewables often did so under regulatory frameworks that guaranteed returns on new construction, shifting risk and cost in ways the public did not always see.
Coal’s role is evolving rather than ending overnight. In parts of the world, and even in some U.S. regions, coal has regained footing because it remains affordable and dispatchable. Developing countries in particular keep coal in their energy mix because it supports industrial growth and grid stability at scale.
That said, the future of coal will not be decided solely by market math; it will also depend on politics. If policymakers mandate retirements or heavily subsidize alternatives without accounting for firming and transmission costs, coal plants will close faster than economics alone would dictate. But those closures come with consequences for price and reliability that are often downplayed in green energy cheerleading.
In short, the data show existing coal plants are still among the lowest-cost sources of electricity in many cases, and the full cost of replacing them with wind and solar is higher than the headlines imply. The conversation about energy policy needs to match real-world engineering and economics, not wishful thinking driven by policy goals. Honest debates should weigh reliability, total system cost, and national energy security alongside environmental aims.
