Energy Governance and Decarbonization Pathways: United Kingdom vs Denmark




Abstract
This article analyzes contemporary energy governance through a theoretical and conceptual perspective integrating the complexity of institutional structures, multi-actor dynamics, and public instruments mobilized for the energy transition. It highlights the importance of polycentric and adaptive governance, capable of reconciling technological innovation, energy justice, social acceptability, and regulatory stability. Two case studies illustrate these dynamics: the United Kingdom, characterized by centralized, competitive, and fragmented governance, faced with political reversals limiting the effectiveness of its renewable policies; and Denmark, exemplary for its decentralized, democratic, and territorially anchored model, favoring citizen involvement and a stable political consensus. The comparison highlights that the success of energy transitions largely depends on the capacity to integrate multilevel governance, citizen participation, and political coherence. The lessons learned recommend ensuring political continuity, promoting decentralization and local mobilization, adopting an integrated approach to economic, social, and environmental dimensions, and developing adaptive and resilient policies in the face of uncertainties. These conclusions open up perspectives for rethinking energy governance mechanisms at the global level and guide future research on the socio-economic impacts of participatory models and the interactions between technological innovation and governance.

1. Introduction

The energy transition is undoubtedly a major challenge of the 21st century, involving a profound transformation of energy production, distribution, and consumption systems. Indeed, in the face of global challenges related to climate change, energy security, and sustainable development, public policies play a central role in guiding this transition toward low-carbon, inclusive, and resilient models. More specifically, energy governance—understood as the set of structures, mechanisms, and interactions between actors involved in policy development and implementation—lies at the heart of this complex process.

Furthermore, the success of energy transitions depends heavily on political and institutional stability, as well as the relevance of the governance models adopted. However, international experience shows that regulatory instability, political reversals, or overly centralized models can hinder the achievement of climate objectives and reduce the effectiveness of renewable policies. Therefore, it is essential to understand the factors that promote or hinder the energy transition in order to design sustainable strategies.

With this in mind, this article aims to compare the energy transition trajectories of the United Kingdom and Denmark, two countries with distinct approaches, in order to identify key success factors and obstacles encountered. Based on this comparative analysis, it offers lessons and recommendations that can inform the energy policies of other countries facing similar challenges.

To do this, the study is based on a comprehensive review of academic literature, institutional reports and official data. It adopts a comparative approach focused on institutional, political and social criteria, including the dimensions of governance, citizen participation and political stability, in order to assess the coherence and effectiveness of energy policies in the two contexts studied.

Finally, our work is structured as follows: Section 2 presents the theoretical and conceptual framework relating to energy governance and the instruments of public transition policies. Section 3 offers an in-depth case study of the United Kingdom, analyzing its energy policies, their evolutions and challenges. Section 4 examines the Danish model, characterized by decentralized and inclusive governance. Section 5 offers a critical comparison between the two countries, highlighting success factors and obstacles encountered. Section 6 formulates lessons and recommendations for other countries engaged in energy transitions, before concluding in Section 7 with a synthesis of the results and future perspectives.

2. Theoretical and conceptual framework

2.1 Energy governance: definition, developments and configurations

Energy governance encompasses all institutional structures, regulatory frameworks and interactions between public and private actors involved in defining, implementing and evaluating energy policies. It extends well beyond the traditional state sphere to a multi-level and polycentric model, in which the roles of national institutions, local authorities, transnational actors, businesses and civil society are intertwined. This network governance, often characterized by flexible and hybrid modes of coordination (Black, 2003), contrasts with more centralized and hierarchical orchestration, adapting to fragmented institutional systems and the growing complexity of energy issues. For example, the G20, without a binding legal mandate, plays a significant normative role in coordinating climate policies and reforming fossil fuel subsidies, mobilizing both public and private actors [1].

Contemporary energy governance corresponds to a “second phase” of the energy transition [2], which goes beyond the simple insertion of renewable energies to initiate a systemic overhaul of the energy sector integrating technological innovation, energy justice, social acceptability, regulatory framework and system stability. This complexity requires adaptive approaches, capable of absorbing the multiple interdependencies between these dimensions.

2.2 Instruments and mechanisms of public energy transition policies

Public policies are essential levers of energy transformation, aiming to correct market failures while encouraging actors to align their practices with climate and sustainability objectives. A diverse range of instruments is mobilized, classified according to their functions [3]:

  • Strategic planning : defining long-term objectives such as carbon neutrality, national climate-energy roadmaps, or sectoral strategies.
  • Economic instruments : direct subsidies, concessional financing, guaranteed purchase tariffs ( feed -in tariffs ), competitive calls for tender, tax incentives.
  • Regulatory framework : energy performance standards, renewable quotas, technical codes.
  • Market mechanisms : carbon quota trading systems, green certificates, contracts for difference.
  • Decentralized devices : net metering , self-consumption, third-party investment.
  • Cross-cutting policies : support for R&D, awareness raising, capacity building.

Innovations such as Corporate Power Purchase Agreements ( PPAs ) are emerging to allow companies to directly purchase green electricity in the long term, improving the bankability of renewable projects and accelerating private decarbonization [3]. These instruments must also take into account the structural change in the electricity system, with the rise of intermittent energy, the need for flexibility, storage and adaptation of networks in a context of planned decline of conventional sectors (coal, nuclear) [2].

2.3 Institutional stability and citizen involvement: keys to a just and effective transition

The success of energy transitions depends on lasting institutional anchoring and strong social support. Stable regulatory and political frameworks are essential to ensure the predictability expected by investors and operators. Political instability, frequent reversals, or budgetary shifts (as in the United Kingdom) weaken transition trajectories.

Furthermore, social acceptability is a determining factor. The 20th century saw a gradual shift towards an increased demand for citizen participation and control over energy infrastructure, particularly local [4]. Many obstacles remain: perception of high initial costs, doubts about the reliability of intermittent systems, local opposition (NIMBY phenomenon) [5]. To address this, governments have increased the number of citizen engagement mechanisms: public consultations, panels, economic incentives, energy cooperatives, community projects, education and awareness-raising [6]. Exemplary experiences, such as the German Energiewende , Danish cooperatives, or American collective solar projects, show that these mechanisms strengthen local ownership and improve the effectiveness of policies [7], [6].

Thus, beyond regulatory stability, inclusive governance, articulating multi-levels and citizen participation, is a fundamental vector for a fair, resilient and legitimate energy transition.

3. Case study: United Kingdom

3.1 History of recent energy policies

Until the 1980s, the UK had a centralised system, dominated by Central Electricity Generating Board (CEGB), favoring large coal and nuclear power plants, hindering the emergence of decentralized renewables. Energy policy was fragmented and poorly coordinated, with R&D focused on large and often commercially unprofitable projects.

The liberalization of the sector in the late 1980s marked a turning point, orienting policies towards security of supply and competitiveness. The Non- Fossil -Fuel Obligation (NFFO) was then introduced to initially support nuclear power, then extended to renewables via guaranteed quotas and tariffs financed by a tax on fossil fuels [8]. Under pressure from European law, the share of funds allocated to renewables increased, with a strict top-down framework favoring competitive calls for tenders targeting 1,500 MW of renewables by 2000 [8].

3.2 Policy Reversals and Impacts

The rate of realization of planned capacities fell sharply from 95% to 8% between NFFO1 and NFFO5, highlighting the limits of highly centralized and competitive governance. Obstacles included the difficulty of obtaining permits, local opposition (particularly for onshore wind), underestimation of costs and lack of penalties [8].

In the 2010s, under the coalition government, a rise in political and local opposition reduced support for onshore wind, while priority shifted to other sectors such as nuclear, with a relaxation of European renewable targets in favour of flexibility [8].

3.3 Consequences for investments and the fight against climate change (CSC)

Excessive centralization and a focus on competition have hampered the territorial adaptation of projects and their local industrialization. Furthermore, the devolution of powers to the Scottish, Welsh, and Northern Irish governments has widened disparities, with Scotland benefiting from coherent territorial governance and strong political consensus, favoring a rapid rise in renewables [9]. Wales and Northern Ireland have performed less well due to more limited resources and political cohesion.

These disparities impact the national ability to achieve its emissions reduction targets. Scotland's success illustrates the importance of strong local governance and multi-stakeholder engagement, while UK fragmentation undermines overall effectiveness [10].

In 2024, according to data published by National Grid [11] , approximately 47% of the electricity generated in the UK came from renewable sources , mainly wind, solar and biomass. However, this share remains fluctuating depending on the seasons and weather conditions. Despite notable progress in the development of offshore wind, long-term objectives remain threatened by successive policy shifts and regulatory uncertainty . This situation underlines the need for more stable and inclusive governance to achieve the 2030 and 2050 climate targets.

3.4 Analysis of the causes of inconsistencies

The British inconsistencies are explained by:

  • Top-down and centralized governance marginalizing territorial specificities [8].
  • A unitary political system limiting regional competences and the formation of strong territorial political networks [8][9].
  • A rise in local opposition and a politicization of projects weakening political coherence [9].
  • Market mechanisms unsuited to innovations, leading to undervalued offers and delays [8].
  • A lack of multi-stakeholder dialogue and territorial anchoring, unlike the Scottish experience [9].

4. Case study: Denmark a decentralized and inclusive model

4.1 Genesis and structuring

Faced with oil dependence in the 1970s, the oil shock triggered a strategic transformation, with the introduction of CO₂ taxes, energy efficiency standards, and sobriety measures. Since the 1980s, Denmark has successfully decoupled economic growth from energy consumption through diversification, the gradual integration of renewables (wind, solar, biomass), and successive energy plans (1976, 1981, 1990, 1996) based on democratic and territorial governance.

4.2 Decentralization and citizen involvement

A fundamental pillar is decentralization: since 1976, local authorities have been empowered to develop their energy plans, promoting alignment between national objectives and territorial dynamics. This framework has enabled the development of a cooperative ecosystem, particularly in wind power, where citizens participate in financing, governance and benefit sharing, supported by dedicated institutions and a strong social consensus (80% support in the 1990s) [11].

4.3 Tangible results

  • 20% of electricity production in 2005 came from wind power.
  • 19% of final consumption of renewable energy in 2009.
  • Target of 30% renewable electricity almost reached in 2010.
  • 15% reduction in GHG emissions between 1990/1995 and 2006.
    At the same time, an incentive environmental tax system has oriented behavior and investments towards energy efficiency.

4.4 Key success factors

Danish success is based on:

  • A stable political consensus.
  • Continued support for R&D (e.g. Risø National Laboratory ).
  • Tax mechanisms guaranteeing the profitability of investments.
  • Integrated planning combining politics, finance, innovation and territorial governance.
  • Strong citizen mobilization through participatory mechanisms ensuring legitimacy and acceptability [11].

5. Comparison and discussion

5.1 Summary of differences and similarities

Both countries began their transition under the impetus of exogenous shocks (oil for Denmark, economic liberalization for the United Kingdom), with a gradual integration of renewables and recourse to various economic and strategic instruments.

However, Denmark has opted for a decentralized, participatory, and territorially rooted model, while the United Kingdom has favored a centralized, liberalized, competitive, and less territorially coherent approach. Social and political consensus is more pronounced in Denmark, unlike in the United Kingdom, where political shifts and weak local integration have slowed the transition.

5.2 Key success factors and obstacles

In Denmark, decentralization, citizen participation, political stability, and support for innovation were major levers. In the United Kingdom, institutional fragmentation, excessive competitive orientation, and a lack of multilevel dialogue were major obstacles.

5.3 Multi-level governance and policy coherence

The Danish model illustrates the effectiveness of articulated multi-level governance, where local dynamics support and complement national policy. Scotland's success in the United Kingdom corroborates this importance. On the other hand, Britain's overly centralized governance, without sufficient coordination between territories, limits the coherence and effectiveness of the transition.

5.4 Limitations of models and specific context

The Danish model, adapted to the size and social cohesion of the country, may be difficult to transpose to larger and more socially fragmented contexts. The British model, despite industrial advances, suffers from weak local roots and political instabilities that harm investor confidence.

6. Lessons and recommendations for other countries

6.1 Strategies to ensure political continuity

Political stability is a prerequisite for ensuring the predictability needed by investors and operators in the energy transition. The examples of Denmark and the United Kingdom show that frequent reversals, such as those observed in the United Kingdom, jeopardize the achievement of climate objectives. It is therefore recommended to establish strong institutional mechanisms, including cross-party commitments or binding legislative frameworks, to ensure long-term policy continuity.

6.2 Importance of decentralization and citizen participation

Decentralization promotes the adaptation of policies to territorial specificities and strengthens local ownership of projects. The Danish model perfectly illustrates how local authorities and citizen cooperatives can become drivers of transition. Active citizen participation improves the social acceptability and legitimacy of policies, thus reducing local opposition. For other countries, it is crucial to integrate these dynamics through participatory mechanisms, inclusive financing mechanisms, and multilevel governance.

6.3 Integration of economic, social and environmental dimensions

A successful energy transition must reconcile economic imperatives, social justice, and environmental protection. Policies must therefore adopt a systemic approach, integrating strategic planning, appropriate economic incentives, support for innovation, and social inclusion measures. This ensures not only technical and economic efficiency, but also social cohesion, a sine qua non for a sustainable transition.

6.4 Adaptive policies and resilience to political change

Finally, the complexity and volatility of political and technological contexts require adaptive policies capable of adjusting to changes and unforeseen events. This requires flexible regulatory frameworks, continuous monitoring, and ongoing multi-stakeholder dialogue. Institutional resilience, supported by inclusive and transparent governance, is a key lever for ensuring the sustainability and success of energy transitions.

7. Conclusion

This comparative analysis between the United Kingdom and Denmark has highlighted the key challenges of energy governance in driving low-carbon transitions. Denmark illustrates the relevance of a decentralized, democratic, and territorially anchored model, promoting citizen ownership, political stability, and a coherent integration of technological, economic, and social dimensions. Conversely, the United Kingdom highlights the risks associated with centralized, fragmented governance, subject to frequent political reversals, which hinder the effectiveness of renewable policies and widen territorial disparities. The success of an energy transition thus depends heavily on the ability to combine institutional stability, social inclusion, multilevel governance, and adaptive flexibility.

The growing complexity of energy systems, marked by the emergence of intermittent renewable energies, digitalization, and the diversification of stakeholders, requires a rethinking of energy governance towards greater resilience and agility. Future governance will need to rely on polycentric architectures capable of effectively coordinating between local, national, and international levels, while integrating the active participation of citizens and private stakeholders. Hybrid mechanisms combining regulation, economic incentives, and multi-stakeholder dialogue appear to be essential levers for addressing the socio-technical and climate challenges of the future.

Future work would benefit from exploring several areas in greater depth: on the one hand, the comparative analysis of governance modalities in more diverse contexts, particularly in developing countries where institutional and social constraints differ significantly; on the other hand, the empirical evaluation of the socio-economic impacts of participatory and decentralized models in the medium and long term. Finally, understanding the interactions between technological innovations (smart grids , storage, blockchain) and energy governance remains a fertile field for shedding light on adaptation and anticipation strategies in the face of rapid and uncertain transitions.
