Poland’s energy story is both a cautionary tale and an inspiring narrative about how a nation heavily dependent on coal has managed to diversify its energy mix significantly within just a few decades. Back in 1990, Poland was essentially synonymous with coal energy, relying on it for nearly three-quarters of its total energy supply. At that time, the country’s energy infrastructure was almost entirely built around domestic coal production, particularly lignite and hard coal, fueling everything from power generation to industrial furnaces and household heating stoves. Fast forward to 2024, and the energy landscape looks quite different—not perfect, but certainly more diversified, resilient, and balanced.

Recent developments in Poland’s energy sector have caught my attention, notably the country’s troubled venture into hydrogen-powered transportation. Reports highlighting the struggles of 21 municipalities seeking government subsidies to offset hydrogen fuel prices—currently around $16.50 per kilogram compared to diesel’s roughly $1.18 per kilogram—are troubling. Logistical inefficiencies further complicate matters; for example, hydrogen buses in Chełm are forced into 28-kilometer round trips merely to refuel, negating potential emissions benefits. Technical challenges have also emerged clearly, as seen in Poznań, where all 25 hydrogen buses had to be withdrawn due to persistent fuel cell failures. These issues strongly suggest that Poland’s hydrogen initiatives may reflect fossil fuel industry interests rather than a sincere push toward sustainable energy transition.

Meanwhile, Poland’s coal generation has dropped rapidly from over 90% of generation to 63% since 1990, all due to renewables. Given Poland’s significant advancements in renewable energy and electrification, shifting the focus toward battery-electric solutions would likely deliver superior efficiency, lower costs, and more meaningful environmental outcomes. As this assessment of the energy transition will reveal, transportation decarbonization is a big part of the remaining journey.

Poland has also been prominently in the news due to its assertive response to Russia’s invasion of Ukraine, positioning itself as a pivotal European ally and advocate for robust support of Ukraine’s sovereignty. Notably, Poland has been central to Ukraine’s integration into the European electricity grid, playing a critical role in connecting Ukrainian infrastructure to continental networks and ensuring energy resilience in the face of Russian aggression. The nation quickly became a frontline hub for humanitarian aid and military logistics, hosting millions of Ukrainian refugees and coordinating substantial assistance flows. Poland’s government has vigorously advocated for stronger EU and NATO positions, pushing aggressively for more comprehensive sanctions against Russia and significantly bolstering its own military capabilities.

And, of course, CleanTechnica‘s fearless leader, Zach Shahan spent a long time living in and working out of Poland before returning to the USA. Apparently the weather is a lot better in Florida.

As a result, I spent some time assembling energy flows for Poland for 1990 and 2024 to contrast the transition and to see what inferences could be drawn from it. The free online Sankey tool I use, Sankeymatic, has its own formatting algorithms and I couldn’t force it to keep Rejected Energy in the upper right where I prefer it, nor could I get the energy services nodes in the same order as LLNL’s Sankey, but the Sankeys are close enough to allow eyeballing for differences.

One striking observation about Poland’s transformation between 1990 and 2024 is the surprising stability in its total primary energy consumption, hovering consistently around 1200 terawatt-hours. What changed dramatically is how this energy is sourced, used and the efficiency of use. Coal’s share in primary energy dropped from roughly 75 percent to just under 45 percent, still significant but demonstrably reduced. In its place, natural gas expanded modestly, and oil consumption grew, mainly driven by transportation demand. Most notably, renewables, virtually nonexistent in 1990, surged significantly by 2024. Wind turbines, photovoltaic installations, biomass heat, and modest hydropower collectively grew to occupy a meaningful slice of the Polish energy pie, contributing around 13 percent of total primary energy. This marks a substantial shift towards decarbonization, driven both by domestic policy decisions and European Union climate commitments.

Another key evolution occurred in the efficiency of energy conversion. In 1990, Poland’s coal-dominated power plants operated at notoriously low efficiencies, often converting less than 35 percent of their fuel into usable electricity, the rest literally going up the smokestack as rejected heat. By 2024, substantial investments had been made into modernizing energy infrastructure. Not only were newer coal and natural gas plants more efficient, but significant renewable generation—wind and solar—came online without the inherent thermal conversion losses of traditional fossil-fuel power generation. The result was noticeably lower rejected energy despite a consistent total primary energy input, meaning Poland now extracts far more useful energy from each unit of fuel.

This efficiency revolution has most visibly impacted residential, commercial, and industrial sectors. Residential heating, for instance, which in 1990 often involved inefficient coal furnaces that dumped vast amounts of heat directly into the atmosphere, had substantially modernized by 2024. Heat pumps, district heating schemes with combined heat and power (CHP) plants, and improved building insulation standards ensured that far more energy delivered to homes actually warmed interiors rather than the local environment. Industrial sectors followed a similar path, adopting advanced electric motors, high-efficiency furnaces, and widespread waste heat recovery systems. These transformations have fundamentally changed how effectively Poland’s energy economy serves its population, delivering more actual comfort, productivity, and service per unit of primary energy consumed.

Yet the transportation sector remains a stark outlier, stubbornly resistant to improvement. Despite overall gains, transport still accounts for a disproportionately high share of rejected energy, largely due to continued reliance on internal combustion engines. Nearly three-quarters of the fuel burned in vehicles in 2024 is wasted as exhaust heat, rather than being converted into propulsion. Electric vehicle adoption remains limited, and while Poland has seen some modest growth in public transit electrification, the overall picture is one of substantial inertia. Certainly the hydrogen bus detour isn’t going to move the needle. This persistent inefficiency presents a critical barrier—not only does it limit Poland’s overall efficiency gains, but it also sustains dependence on imported petroleum, exposing the country to price volatility and geopolitical risks.

The slow electrification of transportation in Poland points clearly to a major policy priority. Poland’s future energy security, economic resilience, and climate credibility now hinge significantly on its willingness and capacity to accelerate the electrification of transport infrastructure. A proactive approach here could replicate the remarkable efficiency and emissions-reduction successes already demonstrated in residential and industrial sectors. Failure to rapidly electrify transportation, however, threatens to stall broader decarbonization efforts, leaving Poland locked into fossil fuel dependency for decades more.

Poland’s ambitious nuclear energy plans, while politically popular, raise questions about their practicality and alignment with the country’s energy transition goals. The first nuclear power plant, initially slated for operation in 2033, has been delayed to 2036, with full completion expected by 2040. This timeline contrasts sharply with the rapid deployment of renewable energy sources; in 2024 alone, Poland added 4 GW of photovoltaic capacity, bringing the total to over 21 GW. Renewables now account for nearly 29% of the nation’s electricity generation, a significant increase from previous years. Given the substantial investment required for nuclear energy—estimated at over PLN 192 billion (approximately USD 49 billion) —and the lengthy construction timelines, it is worth asking whether this approach is the most efficient path forward. Accelerating investments in renewables and grid infrastructure would offer more immediate benefits in reducing coal dependence and enhancing energy security.

Poland’s experiences also offer broader insights for coal-dependent nations elsewhere. Its transition away from coal, while incomplete, demonstrates that substantial diversification and efficiency improvements are achievable even within relatively short periods. It underscores the crucial roles of policy-driven renewables expansion, modernization of infrastructure, and clear efficiency standards. Importantly, Poland’s example reveals how consistent energy consumption does not necessarily imply stagnation—indeed, it reflects how economic growth and improved living standards can be decoupled from greater primary energy use through intelligent investments and planning.

In the grand scheme, Poland’s energy evolution since 1990 is commendable yet incomplete. The strides made in efficiency and renewable adoption deserve recognition, highlighting significant steps toward energy resilience and sustainability. However, the conspicuous inefficiency lingering in transportation signals the next essential frontier. Poland must now accelerate electrification in this sector with urgency and clear-eyed policy ambition. The country should also rethink hydrogen for energy and nuclear generation.
