🏛政策担当者:Warns against one-sided, overly rapid RES shifts and argues for coordinated planning across infrastructure, market design, and regulation to preserve energy security.

Since electrification, economic development has increasingly relied on electricity. Automation, mass production, and rising consumption increase electricity demand, long met mainly by fossil fuels. Rising consumption generates not only production costs but also external costs, including health and environmental ones, resulting from ecosystem degradation (Strojny et al. 2023). This, in turn, strengthens the need to seek more sustainable energy sources.The transition toward renewable energy sources responds to the global increase in demand and resource constraints and simultaneously reduces dependence on fossil fuels (Elkhatat and Al-Muhtaseb 2024). However, a simple 1:1 replacement of fossil sources with renewable energy sources (RES) will not by itself ensure sufficient supply or system stability. An effective transition requires a systems approach-grid expansion, storage, and demand-side management.The European Union does not fully cover its own energy demand. Import dependence reached 60.6%, which creates risks for supply security (Rabbi et al. 2022). Policy should balance the technology portfolio and pursue gradual, coordinated decarbonization. A one-sided and overly rapid shift exclusively to RES may increase the risk of energy shortages and price volatility. Poland is a particularly interesting case, because the power sector is among the most coal-dependent in the European Union. According to Statistics Poland (2025) data, Poland ranks first in terms of the share of coal in electricity generation, and distinct investments in RES are directed toward the energy transition to achieve the goals of the European Green Deal (Kubiczek and Przedworska 2024).This article considers the course of the energy transition in Poland and assesses the related risks to energy security. We indicate that a rapid change in the generation structure (without proper coordination at the levels of infrastructure, the market, and regulation) may generate supply tensions. We also point out that the balance of energy trade affects the actual "carbon footprint" of consumption: imported energy is often generated from fossil fuels outside the country's borders, which means that local emission reductions do not necessarily translate into real decarbonization in global terms.In Poland, electricity prices remained stable for a long time; however, the 2022 crisis, triggered by the war in Ukraine, led to a destabilization of prices on the energy market. The course of changes in electricity prices in Poland in 2021-2025 is presented in Fig. 1. The observable pace of price growth accelerated significantly in Q2 2022, reaching its peak in August 2022. Additionally, as one of the first European Union countries, Poland experienced a suspension of gas supplies from the Russian Federation in April 2022, which had direct consequences for national energy security. However, the supply disruption did not translate into a significant increase in domestic coal generation. Diversified imports and higher commodity prices drove record energy spending on energy carriers in Poland: PLN 193 billion in 2022 compared to PLN 100 billion in 2021 (Lagurashvili 2024).At the household level, higher prices do not always change behavior. Half of Poles declare a lack of readiness to carry out the energy transition even in the face of a significant increase in bills (Hadasik et al. 2025). The entrenched attachment to coal and modernization barriers coexist with relatively moderate public support for transition measures, estimated at around 60% (Lagurashvili 2024). Under these conditions, it is justified to carry out the transition in a systemic manner, based on coherent regulatory frameworks and stable financing mechanisms, so as to translate declarative support into lasting changes on the consumer side.Energy Policy and Security: Poland's Mix ProfileThe geopolitical situation shifted government priorities toward the security of energy supply. This was expressed in the Energy Policy of Poland until 2040 (EPP2040) (Ministry of Climate and Environment 2021) adopted in February 2021, in which the high dependence on a single supplier of natural gas and crude oil was indicated as a barrier to competitive price formation and as a source of vulnerability in the area of foreign policy. The strategy shows cross-government continuity, evidenced by accelerated RES investments and observable shifts in the energy mix. The detailed dynamics of the shares of individual energy sources are presented in Fig. 2. At the same time, dependence on imports of energy carriers is increasing, which widens the gap in the trade balance. According to Statistics Poland (2025), in 2023 Poland already imported over 40% of the electricity used. The increase in imports increases vulnerability to external factors and limits control over the emissions footprint of energy consumed domestically, because its generation takes place outside the national regulatory framework.Energy security is a complex and multidimensional concept. Under the Polish Energy Law, energy security is meeting current and prospective fuel and energy demand in a technically and economically justified way while complying with environmental requirements (International Monetary Fund. European Dept. 2023). According to the Asia Pacific Energy Research Centre, energy security is often framed around the 4 As:• Availability -reliable access to adequate quantities and quality of energy resources within the system. • Accessibility -the practical ability to obtain energy resources and services, shaped by infrastructure, regulation, and geopolitics. • Affordability -energy prices and costs at levels users can bear while keeping the system economically viable.• Acceptability -social and environmental acceptability of how energy is produced and used, including emissions and other impacts.In the literature, energy security is often conceptualized through the "4A", this approach is worth broadening by treating energy security as a special case of security in general -that is, low vulnerability of vital energy systems to threats (Cherp and Jewell 2014).In the international perspective, energy security is analyzed together with other dimensions of the sector. An example is the World Energy Trilemma Index, which emphasizes the interdependence and possible synergies of three pillars: environmental sustainability, energy equity, and energy security. Improving one area may, after all, trigger tensions in the others; therefore, public policies should be designed in a consistent and complementary manner so as to minimize trade-offs and strengthen combined effects (Elkhatat and Al-Muhtaseb 2024).Before the war in Ukraine, generation did not threaten security of supply (Dołęga 2023). However, consumption is growing, and dependence is increasing, all the more so when supply chains have been disrupted. According to PEP2040, RES play a central role; many energy suppliers align their strategies accordingly. State-owned enterprises are implementing PEP2040 and moving toward RES, aiming for zero emissions. However, relying exclusively on RES is risky from the perspective of energy security (Harjanne and Korhonen 2019).• Intermittency and adequacy. Variable RES require balancing capacity and storage.• Grid integration. Scaling RES needs transmission reinforcement and ancillary services.• Economics/institutions. Despite falling LCOE, diffusion depends on market design and policy.In the context of RES, the key challenge for energy security is weather variability. The climate crisis hampers reliable forecasting of production, which forces greater system flexibility and the maintenance of capacity reserves, reducing economic efficiency. Studies indicate that weather factors account for over 32% of power outages (Stankovski et al. 2023). One response is large-scale energy storage, but it involves high investment and operating costs.Extensive RES deployment without adequate grids, flexibility, and balancing may raise import dependence. Poland exhibits heightened vulnerability in this respect, and growing imports limit control over the generation profile and the emissions footprint of energy consumed domestically. The literature emphasizes a conflicting policy mix in which support for RES promotes decarbonization, while capacity mechanisms often compensate for the instability of sources with solutions based on fossil fuels. Shifting the emphasis from such solutions to low-emission technologies, demand-side response, and storage may reduce this contradiction (Kozlova et al. 2023).A pragmatic approach is to combine RES with other low-emission sources. Natural gas emits less than 60% of CO₂ per MWh compared to coal, which is why it can serve a dispatchable function in the transition period (Rabbi et al. 2022). Scenarios for Poland foresee complementarity between RES and gas, taking into account domestic demand, weather conditions, and the need to limit the risk of shortages (International Monetary Fund. European Dept. 2023).Capacity shortages and blackouts carry serious economic and social consequences, including disruptions to production, increased uncertainty, and interruptions in services that are key to a digitized economy. Enterprises can invest in backup sources and energy storage, but higher costs are passed on to prices and weaken competitiveness. To minimize these risks, the transition in Poland should combine the deployment of modern technologies, long-term planning and infrastructure expansion, social participation, and interregional and international cooperation, which strengthens both decarbonization and security of supply (Krawczyńska et al. 2024;Lagurashvili 2024).The energy transition is a necessary response to climate change, but its implementation must be planned, coordinated, and evidence-based. Actions carried out without order increase the risk of shortages, price volatility, and social costs. The variability of weather conditions limits the possibility of r
