The global power sector is undergoing the most intense transformation in its history. However, the ways in which the world’s key economic centers manage this process differ radically. For power system engineers, energy security specialists, and analysts, a comparative analysis of the United States and the European Union models opens up a fundamental professional debate. It highlights a profound paradox of modern energetics: while the politically fragmented US system results in generation mixes naturally tailored to local resources and system physics, the European Union enforces a rigid, uniform, „top-down“ policy. This European dictate consciously ignores the technical, resource, geographical, and economic specificities of individual member states, creating solutions that are certainly sub-optimal for any single country on the continent. On the other hand, robust European grid interconnectivity—historically and very wisely conceived after World War II through the synchronous zone of Continental Europe—demonstrates a clear superiority over the fragmented American approach when it comes to connectivity between individual states. Through a comparative analysis, we will attempt to extract the strengths and weaknesses in the approaches of both the US and the EU and derive a conclusion based on them.

The Federal Level in the US: Control Through Ecology, Markets, and Incentives

The constitutional principle of dual federalism in the US has created a unique division of jurisdiction. Under the constitutional framework, the federal government in Washington lacks the legal authority to directly order any state to implement a specific percentage of coal, gas, nuclear, or renewable energy in its mix. Instead, federal agencies utilize three powerful yet strictly indirect levers:

• Environmental Limits (The EPA): By setting national standards for greenhouse gas emissions and air pollution, the EPA imposes certain economic barriers on fossil fuels. When the modernization costs of aging thermal power plants become unviable, the states and utilities independently make the decision to decommission, modernize, or construct new generation sources in accordance with their needs and capabilities; however, there are no imposed targets or recommended quotas by production type handed down „from above“.
• Interstate Market Regulation (The FERC): The federal regulatory commission oversees the wholesale market and power transmission across state lines. FERC approves the operating rules of Regional Transmission Organizations and Independent System Operators (RTOs/ISOs), thereby influencing which energy sources gain an economic advantage when dispatching their output, yet this functions nothing like the European CBAM model.
• Fiscal Policy and Incentives: Through historic financial packages like the Inflation Reduction Act (IRA), the federal government channels hundreds of billions of dollars into tax credits for clean energy, storage, and nuclear projects. In doing so, the federal level consciously alters the economic calculus on the ground, making new technologies financially attractive, yet without introducing administrative coercion—leaving the final word entirely to the states.

A Difference in Philosophy—The European Stick vs. the American Carrot: While Europe employs fiscal pressure and penalties (such as the ETS and CBAM) as a stick to force the power system toward decarbonization, the US federal government, through the Inflation Reduction Act (IRA), has opted for the completely opposite approach—using a massive system of subsidies and tax credits as a carrot. Instead of levying a tax on power plants for their CO2 emissions, Washington effectively rewards them (via tax breaks) for producing clean energy, extending the operational life of nuclear plants, or installing carbon capture and storage (CCS) systems. While Brussels punishes (via the ETS), Washington rewards (via the IRA). This further demonstrates that the American federal level alters the economic landscape through financial incentives, yet preserves the sovereign right of individual states to determine whether and how to utilize these credits, completely avoiding the imposition of a centralized CO2 tax burden from above, or the imposition of solutions that run contrary to the tenets of security of supply for both the population and the economy.

The State Level: Direct Engineering and Statutory Control

While Washington guides broader economic trends, the individual states themselves keep their „hand on the switch.“ They control their generation mix through state Public Utilities or Public Service Commissions (PUCs/PSCs) and legislative mandates.

State commissions possess absolute administrative power over utilities. They approve long-term development roadmaps known as Integrated Resource Plans (IRPs), issue certificates for constructing new capacities, and regulate retail consumer tariffs. If a state intends to alter its mix, its commission can simply deny permits for undesirable technologies or declare such investments „imprudent,“ shifting the financial risk back to the investor. Furthermore, states enact their own laws—such as Renewable Portfolio Standards (RPS) or Clean Energy Standards (CES)—prescribing percentages and timelines tailored to their specific capabilities.

How this division of jurisdiction functions in practice, and how it results in an energetic optimum tailored to the resource-technical capabilities and economic needs of each individual state, is best illustrated by comparing two states with completely opposing visions: California, with its low energy intensity where the economy is driven by digital and financial flows and GDP growth is based on innovations, technology, intellectual property, and services; and West Virginia, with its exceptionally high energy intensity where the economy is built upon industry and mining that demand constant and cheap baseload power, and GDP growth is rooted in the extraction of natural resources, raw materials, and heavy industry.

California: Aggressive Decarbonization and the „Duck Curve“

California serves as a laboratory for the green transition. Its mix is characterized by a high share of renewables—solar power covers over 20%, while wind, hydro, and nuclear energy form the rest of the carbon-free base. Natural gas is used primarily for balancing, while coal has been eliminated. Through Senate Bill 100 (SB 100), the state legally bound utilities to achieve a 100% clean energy mix by 2045. Additionally, it utilizes an internal carbon market (Cap-and-Trade) and a decentralized procurement mandate (Resource Adequacy).

However, the high level of integration of solar capacity has confronted California with a severe engineering challenge known as the „duck curve.“ During midday, when the sun is at its peak, solar generation floods the grid, causing a drastic drop in net load and creating a deep sag in the daily consumption profile. When the sun sets and demand sharply spikes, system dispatchers (CAISO) face extreme demand ramps (ramping), requiring them to spin up thousands of megawatts of flexible gas turbine generation within a few hours to prevent grid collapse. Yet again, this state has been left with the sovereign right—even at the expense of higher electricity prices for its economy and population—to organize the operations of its power system based on its specific needs and type of economy, maximizing its available resources in alignment with its own political ideology. This remains entirely legitimate because, to reiterate, it was not imposed from above; rather, the state was left to define its own optimal generation mix.

West Virginia: Safeguarding Baseload Energy from Coal

On the opposite end of the spectrum lies West Virginia, where coal still covers nearly 90% of total electricity generation. This state relies on traditional, vertically integrated monopolies. The state Public Service Commission (PSC) strictly controls investments with the primary objective of maintaining low rates for industry and protecting domestic coal mining. West Virginia lacks binding renewable targets; on the contrary, it has passed legislation making it extremely difficult for utilities to retire aging coal-fired plants. Any eventual integration of solar capacity (through recent acts like the Comprehensive Energy Policy) does not stem from ecological ideology, but rather because tech giants (such as Amazon and Microsoft) condition the construction of their data centers on the availability of green energy. This represents pure economic pragmatism at the local level. In this case as well, the federal administration respects the local specificities of the individual state.

The economic model and political ideology of a state translate directly into end-consumer bills. California features some of the highest electricity rates in the continental US due to the costs of integrating renewables, energy storage, and grid modernization. Conversely, West Virginia, by relying on domestic coal and a traditionally regulated monopoly, succeeds in keeping its rates well below the national average.

According to the latest official data from the US Energy Information Administration (EIA), a comparative breakdown of rates (in cents per kilowatt-hour, ¢/kWh) is as follows:

The European Absurdity: The Triumph of Ideology Over the Laws of Physics

While the American system allows California and West Virginia to operate in accordance with their respective resources, economic models, and specific needs, the European Union has chosen a path that defies techno-economic logic. Through packages like „Fit for 55“ and the RED III directives, Brussels prescribes uniform percentages and timelines for decarbonization across all member states, while imposing a series of additional burdens regarding the usage of necessary, stable baseload generation capacities. It should also be borne in mind here that gas does not exist as a resource within the EU, which presents an additional compounding complication within such a framework.

The attempt to forge a „unified European generation mix“ suffers from three fundamental systemic flaws:

• Disregarding Geographical Reality and National Specificities: Mandating that Poland or Serbia (which historically rely on coal and feature a low or lower number of sunny days) carry out decarbonization within the same timelines and percentages as Greece, Albania, or Spain is an engineering absurdity. Forcing the installation of technologies where capacity factors are inherently low dramatically escalates costs and compromises the stability of the entire power system.
• The Fallacy of Cross-Border Connectivity and Markets as Standalone Solutions: The European concept relies too heavily on the assumption that strong interconnections combined with market mechanisms will automatically resolve the variability of renewables and ensure security of supply. However, meteorological phenomena like Dunkelflaute (prolonged periods of no wind and no sun across entire Central Europe) prove that a uniform mix leaves the entire continent vulnerable and energy-deficient at the exact same time. The result is increasingly frequent negative prices on European power exchanges (such as EPEX SPOT), which destabilizes the economic model for investments, while on the other hand causing energy deficits during periods of the day, or year, when sun and wind are unavailable in sufficient quantities. This is accompanied by extremely rapid, large-scale, and volatile power flow surges along the affected corridors during the described transitions, which further complicates and endangers system operation from the standpoint of security and operational stability.
• The Economic Cost of Sub-Optimality: When a generation mix that does not match a nation’s natural specificities, resources, and technical capabilities is forced upon it, the economic toll is paid by that country’s industry and end consumers. Today, European nations spend hundreds of billions of euros on ancillary services, redispatching, balancing, and expensive, underdeveloped energy storage systems just to artificially maintain the stability of a system that has practically been destabilized by an administrative decree handed down „from above“ over the course of the ongoing transition.

The Incongruity of Uniformity with Diverse Economic Architectures: As demonstrated by the US model, a nation’s power generation mix must directly correspond to its specific macroeconomic architecture and structural energy intensity. Forcing a service-and-innovation-driven template onto an economy heavily anchored in material production is a fundamental systemic failure. The uniform Brussels model represents a catastrophic trajectory for economies structurally analogous to West Virginia, Poland, or Serbia—where heavy industry, mining, and manufacturing form the backbone of GDP and demand an uninterrupted, affordable baseload shield. Conversely, a high-cost, high-variability decarbonization framework remains a legitimate and affordable luxury for an economy like California’s. Because California’s wealth is generated through low-energy-intensity digital and financial flows, its corporate elite can easily absorb inflated utility rates. Imposing that same financial and technical burden on resource-dependent nations collapses their industrial competitiveness, turns vital production lines obsolete, and forces a choice that runs entirely contrary to the basic tenets of national economic survival.

Nuclear Energy: An Ideological Rift in Europe vs. Pragmatic Consensus in the US

Nuclear energy perfectly mirrors the divergence between these two models. In Europe, it has become a battlefield for a deep ideological and geopolitical war. We witness German dogmatism, where Berlin decommissioned technically flawless nuclear power plants under its Energiewende strategy and temporarily revived coal, contrasted against French pragmatism, which relies on nuclear plants for 70% of its generation. Years of debate surrounding the EU Green Taxonomy created an investment vacuum in Eastern and Central Europe (e.g., the Czech Republic, Poland, Slovakia), where nations view nuclear energy as the only realistic replacement for coal but find themselves constrained by rigid administrative centralism from Brussels.

Conversely, a clear engineering and regulatory consensus exists in the US regarding the value of nuclear power as a 100% reliable, zero-emission baseload source. When green California faced blackout threats and the reality of the „duck curve,“ the state commission (CPUC) made a swift, pragmatic decision to extend the operation of the Diablo Canyon nuclear plant until 2030. Similarly, traditionalist West Virginia officially repealed its decades-old statutory ban on nuclear construction in 2022, recognizing it as a stable replacement for old coal plants that satisfies federal standards. Through federal incentives via the IRA package, Washington provides technology-neutral support to the nuclear sector, leaving states with the autonomy to choose their own timeline for integration.

The Lesson of Texas

Texas (ERCOT) is frequently cited as the third pole of the American system, offering a distinct engineering lesson in its relationship with federal mandates. Texas has no green mandates, no „Fit for 55“ targets, nor any legal obligation for top-down decarbonization, yet its vast geographical expanses and solar and wind potential have attracted immense private capital into wind and solar farms. According to European political logic, Texas should be lagging behind in the transition. However, reality proves otherwise—Texas has produced the largest renewables boom in the US. In Texas, wind farms and solar parks are not built because it is politically fashionable, but because the vast expanses of West Texas, high insolation, and wind potential have created conditions where the levelized cost per megawatt-hour from these sources is the lowest on the open market. In other words, this type of generation perfectly matches the resource profile of this state. Texas opted for a model of extreme market deregulation and grid isolation specifically to evade federal oversight. Yet, backed by the enormous natural gas reserves with which the state is blessed, alongside a powerful fleet of gas and coal-fired power plants, it succeeds in keeping electricity prices affordable for both its population and its economy.

The critical drawback, however, is its isolation and the reality of being left entirely to fend for itself during extreme situations. In fact, it is precisely the Texan example that brings the immense advantage and superiority of the European system interconnection approach into sharp focus, even when you have a system whose generation mix is otherwise soundly conceived. The European ENTSO-E grid is an engineering masterpiece of synchronization and solidarity. While Texas was left to fend for itself and suffered a systemic breakdown during Winter Storm Uri due to its deliberate electrical isolation, the European cross-border connectivity model ensures that states can rely on technical support and emergency energy exchanges with their neighbors at any given second. European interconnection dramatically elevates the security of supply, mitigates local outages, and represents a technically incomparable, far safer concept than isolated grid islands like ERCOT in America—however, how long it will remain that way depends heavily on the approach to planning and controlling the generation mix in Europe. A strong interconnection backed by inadequate national generation mixes ultimately becomes a weak interconnection. The role of interconnection must primarily remain focused on mutual assistance and cross-border support between systems, rather than taking the form currently envisioned by the EU legislator.

Conclusion

A comparative analysis unequivocally indicates that power system engineering tolerates neither extreme political dogmatism, over-reliance on markets, nor operational isolationism. The uniform European approach to generation mix planning suffers from an ideological optimism that believes the laws of physics can be tamed by administrative templates from Brussels through the „Fit for 55“ framework, creating sub-optimal and expensive local systems. On the other hand, the American dual federalism model shows that states must have development autonomy, yet the lesson of Texas teaches us that this freedom, if it veers into extreme deregulation and isolation, invites systemic risk.

The final conclusion is clear: Europe urgently needs an energy sovereignty approach, geographical pragmatism, and strict respect for the technical, resource, and economic specificities of each individual country, rather than the imposition of uniform templates when planning national generation mixes. At the same time, it is an extraordinary achievement and a major engineering advantage that European systems are exceptionally interconnected. This robust cross-border interconnection serves as the ultimate pillar of stability keeping Europe safe from a Texas-style scenario—though whether it will save it from a Brussels-style scenario remains to be seen.

The success of future energy policy lies precisely in this synthesis: maintaining world-class cross-border technical connectivity and solidarity, while simultaneously restoring the freedom of each sovereign state to develop its generation mix in an engineered, optimal, natural, and secure manner with limited reliance on market mechanisms and zero interference from Brussels in that process—thereby preserving the sovereign right of each state to manage its national production mix. What we need is a unique union of well-interconnected sovereign power systems in Europe. Perhaps Europe needs this on a political level as well 😊. Strong interconnectivity between strong, sovereign national power systems, backed by sound geographical pragmatism and national sovereignty. By taking the single best element from each of these two examples—the US and the EU—we have ultimately arrived at the best possible answer for Europe, and for every individual nation on the continent, on how and where to go next in the future.
