Abstract

This research report undertakes an exhaustive examination of the concept of energy security within the United Kingdom, focusing on the indispensable role of onshore wind energy in fortifying national resilience, significantly reducing structural dependence on imported fossil fuels, and comprehensively mitigating the pervasive impact of volatile global energy prices. The analysis delves deeply into the complex geopolitical dimensions influencing energy security, explores the multifaceted economic implications arising from a diverse and balanced energy portfolio, and scrutinizes the strategic measures meticulously employed by the UK government and industry stakeholders to achieve a robust state of energy independence. By rigorously evaluating the progressive integration and projected expansion of onshore wind into the UK’s broader energy mix, the report provides critical insights into the profound long-term implications for national sovereignty, macroeconomic stability, and environmental sustainability. It argues that onshore wind, as a mature, cost-effective, and domestically available technology, is not merely a component of the UK’s decarbonisation strategy but a cornerstone of its future energy security architecture.

1. Introduction

Energy security, at its core, represents a nation’s capacity to ensure the uninterrupted availability of primary and secondary energy sources at a competitive and affordable price, alongside the accessibility and sustainability of these supplies over the long term. For the United Kingdom, an island nation with a rich industrial past largely built on indigenous fossil fuel resources that are now in decline, achieving robust energy security involves a complex interplay of strategic imperatives: decisively reducing a historical and economically vulnerable reliance on imported fossil fuels, aggressively diversifying its energy supply portfolio across multiple technology types and geographical origins, and effectively mitigating the inherent volatilities and disruptive impacts emanating from global energy market fluctuations. In this evolving landscape, the renewed adoption and ambitious expansion of onshore wind energy have emerged as central, non-negotiable strategies in this critical national endeavour. This comprehensive report meticulously explores the pivotal role of onshore wind in bolstering the UK’s energy security framework, examining its intricate geopolitical underpinnings, profound economic implications, and overarching strategic dimensions within the context of a global energy transition.

Historically, the UK benefited significantly from the exploitation of North Sea oil and gas reserves, which peaked in the late 1990s and early 2000s, providing a period of substantial energy self-sufficiency. However, as these reserves have diminished, the UK has progressively transitioned back to being a net energy importer, particularly for natural gas, electricity, and petroleum products. This shift has exposed the nation to the inherent risks associated with global supply chain disruptions, commodity price volatility, and geopolitical leverage exerted by exporting nations. The strategic imperative to reverse this trend and build a resilient, independent energy system has therefore gained unprecedented urgency, particularly in the wake of recent global events. Onshore wind, characterised by its domestic sourcing, technological maturity, and increasingly competitive cost profile, offers a powerful antidote to these vulnerabilities, representing a tangible step towards genuine energy independence and a stable, sustainable energy future for the UK. This report will unpack these elements, providing a holistic view of onshore wind’s strategic value.

2.1. Global Energy Dynamics and Volatility

The geopolitical landscape is an omnipresent and often unpredictable force that profoundly shapes national energy security. Global events, ranging from regional conflicts and acts of terrorism to major policy shifts by key energy-producing nations or technological breakthroughs, possess the capacity to severely disrupt energy supply chains, distort market equilibrium, and trigger extreme price volatility. A salient contemporary example is the 2022 full-scale invasion of Ukraine by Russia, which unleashed a seismic shockwave across global energy markets. Russia, a major global supplier of natural gas, oil, and coal, saw its energy exports become entangled in international sanctions and retaliatory measures, leading to unprecedented surges in European gas prices and significant reorientations of global energy trade flows (International Energy Agency [IEA], 2022). This crisis unequivocally demonstrated the acute vulnerabilities inherent in relying heavily on a single or a limited number of external energy suppliers, particularly those operating under authoritarian regimes or engaged in geopolitical assertiveness.

The UK, though not directly dependent on Russian gas imports for the majority of its supply, was nonetheless deeply impacted by the ensuing interconnectedness of European gas markets and the ripple effect on global LNG prices. The price of wholesale gas across Europe soared, directly translating into higher electricity costs for UK consumers and businesses, given gas’s significant role in the UK’s electricity generation mix (Energy UK, 2022a). This event served as a stark, immediate catalyst, prompting nations worldwide to critically reassess their energy dependencies and recalibrate their security strategies towards greater self-reliance and diversification. Beyond immediate conflicts, other geopolitical risks such as maritime chokepoints (e.g., the Strait of Hormuz, Suez Canal) through which a substantial proportion of global oil and gas traverses, state-sponsored cyber-attacks targeting critical energy infrastructure, and political instability in major producer regions (e.g., the Middle East, North Africa) continuously underscore the fragility of international energy supply lines. These dynamics highlight an imperative for the UK: to build an energy system that is fundamentally insulated from such external shocks, thereby enhancing its resilience and capacity for independent action on the global stage.

2.2. The UK’s Evolving Energy Dependencies

Historically, the UK’s energy narrative was one of relative abundance, propelled by the discovery and exploitation of North Sea oil and gas. This era, peaking in the late 1990s, afforded the UK a significant degree of energy self-sufficiency and a net exporter status, providing both economic benefits and strategic insulation from global market vagaries. However, the natural decline of these mature fields, coupled with sustained domestic demand, inexorably led to the UK becoming a net importer of energy from the early 2000s (Department for Business, Energy & Industrial Strategy [BEIS], 2021). This shift introduced a structural vulnerability, exposing the nation to the geopolitical risks and price fluctuations intrinsic to international energy markets.

Specifically, the UK’s reliance on imported natural gas has grown substantially, with significant volumes sourced via pipeline from Norway and Belgium (which often carries gas from other European sources), and increasingly through liquefied natural gas (LNG) imports from diverse origins including Qatar, the United States, and further afield (Ofgem, 2023). While diversification of LNG sources offers some mitigation against single-supplier risk, it does not fully insulate the UK from global price shocks or the broader geopolitical dynamics affecting the global gas market. This dependency has tangible implications not only for national sovereignty – as energy security often underpins foreign policy flexibility – but also for the economic stability of households and industries, which directly bear the brunt of elevated and volatile energy costs.

By strategically investing in and rapidly deploying domestic renewable energy sources, particularly mature and scalable technologies like onshore wind, the UK actively seeks to reverse this trend of increasing import dependency. Onshore wind generates electricity within the UK’s borders, using an indigenous, inexhaustible fuel source (wind) that is not subject to international pricing mechanisms, resource depletion, or geopolitical manipulation. This domestic generation capacity directly displaces the need for imported fossil fuels, thereby enhancing the UK’s energy independence, strengthening its balance of payments, and significantly reducing its exposure to external energy shocks. Such a strategic pivot not only fortifies the nation’s energy security but also intrinsically strengthens its geopolitical standing, enabling it to pursue its national interests with greater autonomy and resilience (Slaughter and May, 2022).

3. Economic Implications of Diverse Energy Portfolios

3.1. Cost Competitiveness and Affordability of Onshore Wind

One of the most compelling arguments for the widespread deployment of onshore wind energy is its exceptional cost-effectiveness within the UK’s diverse energy portfolio. Over the past decade, onshore wind has consistently demonstrated a remarkable trajectory of cost reduction, driven by advancements in turbine technology, economies of scale in manufacturing and installation, and increasing developer experience (IRENA, 2023). This progress has firmly established onshore wind as one of the cheapest forms of new electricity generation available today, often outcompeting new fossil fuel plants on a Levelized Cost of Energy (LCOE) basis.

The LCOE metric, which calculates the average total cost of building and operating a power-generating asset over its lifetime, divided by the total electricity output, consistently places onshore wind at a highly competitive level. Recent analyses, including those from the UK government and independent bodies, indicate that onshore wind LCOE figures are frequently lower than those for new gas-fired power plants, even before accounting for carbon pricing (BEIS, 2020; Lazard, 2023). This cost advantage is primarily due to the absence of fuel costs once the turbines are erected, which contrasts sharply with gas generation that remains exposed to volatile international commodity markets.

Until 2015, onshore wind development in England faced a ‘de facto ban,’ a policy decision that effectively excluded new projects from the government’s primary financial support mechanism, Contracts for Difference (CfD), and imposed stringent planning restrictions (House of Lords Economic Affairs Committee, 2022). This policy, driven by local opposition concerns, curtailed domestic development at a time when costs were rapidly falling globally. The subsequent removal of this ban in 2023, and the government’s renewed commitment through initiatives like the Onshore Wind Taskforce Strategy, signals a critical policy correction (Department for Energy Security and Net Zero [DESNZ], 2025a). The aim is to unlock substantial new capacity, with ambitious targets projecting 27-29 GW of onshore wind by 2030, a near-doubling from current levels. This expansion is explicitly framed as a means to provide consumers with ‘some of the cheapest homegrown power available,’ directly addressing the cost-of-living crisis and reducing reliance on expensive imported fuels (DESNZ, 2025b). By prioritising onshore wind, the UK can lock in long-term, stable electricity prices, thereby shielding consumers and industries from future fossil fuel price shocks and enhancing overall economic stability.

3.2. Economic Benefits and Job Creation

Beyond cost savings for consumers, the extensive development of onshore wind projects delivers significant and tangible economic benefits across the UK economy, primarily through substantial job creation, attraction of investment, and stimulation of local economies. The lifecycle of an onshore wind farm, from initial conception through to decommissioning, encompasses a wide array of skilled labour and economic activity.

In its nascent stages, the onshore wind sector already demonstrated considerable economic impact. As early as 2011, onshore wind directly supported over 8,600 jobs and contributed an estimated £548 million to the UK economy (DESNZ, 2025c). These figures have undoubtedly grown with increasing capacity and sophistication of the industry. The government’s renewed commitment to an ‘onshore wind revolution’ is projected to create many thousands of new jobs by 2030, spanning a diverse range of disciplines. These include high-skilled roles in engineering (electrical, mechanical, civil, structural), advanced manufacturing (for turbine components such as blades, towers, and nacelles), project management, construction and installation, grid connection specialists, and crucial long-term positions in operations and maintenance (O&M) (DESNZ, 2025b).

Furthermore, the economic benefits extend to the wider supply chain, stimulating demand for materials, transportation, and ancillary services (e.g., environmental consulting, legal services, financial planning). Investment in onshore wind projects attracts both domestic and international capital, contributing to Gross Fixed Capital Formation and fostering a vibrant green economy. Local communities hosting wind farms also experience direct economic advantages through community benefit funds, which can be deployed for local infrastructure, social projects, or reduced energy bills for residents. Landowners receive lease payments, providing a stable income stream. This localised economic activity, coupled with the national industrial development, positions the UK as a leader in the global transition to sustainable energy, fostering innovation, attracting talent, and creating a robust, future-proof industry that contributes significantly to long-term economic stability and growth.

4. National Strategies for Achieving Energy Resilience

Many thanks to our sponsor Focus 360 Energy who helped us prepare this research report.

4.1. Strategic Reserves and Grid Modernisation

Achieving comprehensive energy resilience necessitates a multi-pronged national strategy that extends beyond simply increasing generation capacity. It involves ensuring the robustness of the entire energy system, from fuel supply to final consumption. The UK has historically relied on strategic reserves, primarily for oil and gas, to buffer against short-term supply disruptions. These include underground gas storage facilities (though their capacity has been debated and reduced over time) and obligations on fuel suppliers to hold minimum stock levels (Ofgem, 2023). However, the evolving energy landscape, with a growing reliance on intermittent renewables, demands a more sophisticated approach, placing grid modernisation at the forefront of resilience strategies.

Investments in grid modernization are paramount to facilitate the efficient and reliable integration of growing renewable energy sources, including onshore wind. The conventional grid, largely designed for centralised, dispatchable fossil fuel power stations, is ill-equipped to handle the decentralised and variable nature of renewables without significant upgrades. Key aspects of grid modernisation include:

1. Transmission and Distribution Reinforcement: Upgrading existing power lines and building new ones, particularly in areas with high renewable potential (often remote and sparsely populated), to overcome congestion and transmit power effectively to demand centres.
2. Smart Grid Technologies: Implementing advanced digital technologies for real-time monitoring, control, and optimisation of electricity flow. This includes smart meters, which enable dynamic pricing and demand-side response, allowing consumers to adjust their energy consumption based on price signals or grid needs.
3. Energy Storage Solutions: Deploying large-scale battery storage, pumped-hydro storage, and potentially future hydrogen storage, to absorb excess renewable energy during periods of high generation and release it during periods of low generation or peak demand. This helps to smooth out intermittency and provide grid stability services (National Grid ESO, 2023).
4. Enhanced Forecasting: Developing more accurate weather forecasting models and advanced analytics to predict renewable generation output with greater precision, enabling better grid management and balancing.

The government’s Clean Power Action Plan, which includes the ambitious target of nearly doubling onshore wind capacity by 2030, explicitly recognises the necessity of rapid grid development and potential repowering of existing sites (DESNZ, 2025a). This requires streamlined planning processes for new transmission infrastructure and significant capital investment, often overseen by National Grid Electricity System Operator (ESO), to ensure a stable, reliable, and secure energy supply capable of handling a high penetration of renewables.

4.2. Interconnections and Energy Diplomacy

The UK’s energy security strategy extends beyond domestic infrastructure to encompass robust international collaborations, notably through strengthening electricity interconnections with neighbouring countries and engaging in proactive energy diplomacy. Electricity interconnectors – submarine or underground cables that link national grids – serve as critical arteries for enhancing energy resilience and optimising resource utilisation. The UK currently has operational interconnectors with France (IFA, IFA2), Belgium (Nemo Link), the Netherlands (BritNed), Norway (North Sea Link), and Denmark (Viking Link, operational from 2023) (National Grid Ventures, 2023). These links enable the UK to import or export electricity, providing several key benefits:

• Diversification of Supply: Access to a wider pool of generation sources, reducing reliance on domestic capacity alone.
• Balancing Intermittency: Allowing the UK to import power when domestic renewable generation (e.g., wind) is low and export surplus renewable power when generation is high, thereby reducing curtailment and increasing system efficiency across a broader European network.
• Price Arbitrage: Importing cheaper power during periods of low demand or high renewable output in interconnected countries and exporting when prices are higher in the UK.
• Enhanced Reliability: Providing an emergency backup in the event of domestic generation failures or sudden demand surges.

Beyond physical infrastructure, energy diplomacy plays a crucial role. This involves engaging in strategic dialogues, multilateral forums (e.g., G7, G20, IEA), and bilateral agreements with key energy partners to coordinate policy, share best practices, and collectively address challenges such as supply disruptions or market manipulation. The UK’s active participation in international climate negotiations (e.g., COP conferences) and its commitment to global decarbonisation efforts also positions it as a leader, influencing international energy standards and promoting a collective shift towards sustainable energy systems (UK Government, 2022). By diversifying energy import sources – both physically through interconnectors and geopolitically through collaborative agreements – the UK aims to mitigate risks associated with geopolitical tensions, supply disruptions, and to collectively build a more resilient and integrated European energy market, crucial for the security of all participating nations, especially in a post-Brexit context.

5. Role of Onshore Wind in a Secure Energy Supply

Many thanks to our sponsor Focus 360 Energy who helped us prepare this research report.

5.1. Contribution to Renewable Energy and Net-Zero Targets

Onshore wind is not merely an option but a cornerstone in the UK’s ambitious journey towards a secure, decarbonised, and net-zero energy system. The UK government has committed to a legally binding target of achieving net-zero greenhouse gas emissions by 2050, with an interim target of decarbonising the electricity system by 2035 (DESNZ, 2023). These targets necessitate a rapid and systemic transformation of the energy generation landscape, moving decisively away from fossil fuels towards clean, renewable alternatives.

Onshore wind plays a dual role in this transition: directly contributing to renewable energy targets and displacing carbon-intensive generation. Currently, onshore wind is a significant component of the UK’s renewable electricity generation, alongside offshore wind and solar PV. The government’s strategy, while heavily emphasising offshore wind capacity growth from around 15 GW to an ambitious 50 GW by 2030, increasingly recognises that onshore wind must also contribute substantially (DESNZ, 2025b). The renewed political will to unlock up to 27-29 GW of onshore wind capacity by 2030 underscores its critical role. This projected growth, coupled with existing assets, positions onshore wind as a major contributor to the UK’s overall renewable energy mix, providing a substantial proportion of the clean electricity required to meet the 2035 decarbonisation target.

Its contribution is integral to the broader strategy of ‘energy mix diversification,’ a fundamental principle of energy security. A diversified energy mix, incorporating multiple renewable technologies (wind, solar, hydro, biomass) alongside potentially nuclear and advanced fossil fuels with Carbon Capture, Utilisation, and Storage (CCUS), ensures greater resilience against individual technology failures, resource limitations, or environmental variability. Onshore wind’s proven performance, rapid deployment potential, and declining costs make it a powerful tool for accelerating the transition to a low-carbon electricity grid. By contributing a large volume of clean, domestically generated electricity, onshore wind directly supports the UK’s commitment to decarbonising its electricity sector, reducing greenhouse gas emissions, and aligning with international climate agreements, thereby enhancing the UK’s reputation as a climate leader.

5.2. Enhancing Energy Independence and System Resilience

One of the most profound contributions of onshore wind to the UK’s energy security is its direct enhancement of energy independence. By significantly expanding domestic electricity generation from an indigenous and inexhaustible resource – the wind – the UK directly reduces its structural reliance on imported fossil fuels. This strategic shift has several layers of benefit for energy independence and overall system resilience.

Firstly, every megawatt-hour (MWh) of electricity generated by onshore wind displaces a corresponding MWh that would otherwise need to be generated by fossil fuel plants, predominantly gas, or imported via interconnectors. This directly translates into a reduced requirement for gas imports, which are subject to global price volatility and geopolitical influence. In an era where gas prices have soared due to international events, domestic wind power provides a stable, predictable, and ultimately cheaper alternative, insulating consumers and businesses from external price shocks. The economic value of avoiding these import payments is substantial, bolstering the UK’s balance of payments and retaining capital within the domestic economy.

Secondly, onshore wind improves the UK’s ‘security of supply’ metric, which measures the reliability and adequacy of the electricity system to meet demand. By adding robust, dispatchable (within its operational limits) generation capacity that is geographically dispersed across the country, onshore wind contributes to a more resilient grid. While onshore wind is intermittent, its output can be reasonably forecast, and its contribution, when combined with other renewables, flexible generation, and storage, improves the overall adequacy of the system. This directly reduces the ‘Lost Load Expectation’ (LLE), a key indicator of energy security reflecting the anticipated amount of energy demand that cannot be met over a given period (National Grid ESO, 2023).

Moreover, the environmental co-benefits of reduced fossil fuel consumption are substantial. Decreased reliance on imported gas not only enhances energy independence but also translates into lower greenhouse gas emissions, less air pollution, and improved public health outcomes. This alignment of energy security with environmental objectives is a defining characteristic of modern energy policy. In essence, by investing heavily in onshore wind, the UK is not only shoring up its immediate energy supply but also building a fundamentally more robust, independent, and environmentally responsible energy system for the long term, thereby strengthening its national security posture and its capacity to act autonomously in a complex global arena.

6. Challenges and Mitigation Strategies for Onshore Wind Integration

While the strategic benefits of onshore wind are clear, its extensive integration into the UK’s energy system presents several challenges that require proactive and innovative mitigation strategies. Addressing these challenges is crucial for unlocking the full potential of onshore wind and ensuring a smooth, sustainable transition.

Many thanks to our sponsor Focus 360 Energy who helped us prepare this research report.

6.1. Public Acceptance and Planning Complexities

One of the most persistent challenges for onshore wind development in the UK has been securing widespread public acceptance and navigating complex planning regulations. Concerns often fall under the ‘Not In My Backyard’ (NIMBY) phenomenon, where local residents may support renewable energy in principle but oppose specific developments near their homes. Key public concerns typically revolve around:

• Visual Impact: The perceived impact of large turbines on landscapes, particularly in areas designated for scenic beauty (e.g., National Parks, Areas of Outstanding Natural Beauty), or simply on local views (Energy UK, 2022b).
• Noise Concerns: The audible sound generated by turbine blades, though modern turbines are significantly quieter than older models, can still be a source of local complaint at certain distances and wind conditions.
• Ecological Impact: Potential effects on local wildlife, particularly birds and bats, although thorough environmental impact assessments (EIAs) are mandated to minimise such risks.
• Property Value: Perceived or actual devaluation of nearby properties.

Mitigation Strategies:

1. Community Engagement and Benefits: Proactive and transparent engagement with local communities from the earliest stages of project development is vital. Offering substantial community benefit funds (e.g., contributions to local projects, reduced energy bills for nearby residents) can foster local buy-in and demonstrate tangible advantages of hosting wind farms.
2. Strategic Siting: Prioritising sites in less densely populated areas, industrial lands, or areas where visual impact is minimal, while avoiding highly sensitive landscapes. Repowering older, smaller turbines with newer, more efficient ones on existing sites can also mitigate new visual impacts.
3. Enhanced Planning Framework: The recent removal of the ‘de facto ban’ and reforms to national planning policy for England aim to streamline the planning process for onshore wind. This includes giving greater weight to the need for renewable energy, providing clearer guidance for local authorities, and empowering local communities to express support for projects in their area (DESNZ, 2025a).
4. Robust Environmental Impact Assessments: Ensuring that all new projects undergo rigorous EIAs to identify and mitigate potential negative impacts on ecology, noise levels, and visual amenity.

6.2. Grid Infrastructure and Intermittency Challenges

The inherent intermittency of wind power – it only generates when the wind blows – poses significant challenges for grid stability and reliability. Integrating a rapidly growing volume of variable renewable energy into a grid historically designed for constant, dispatchable power sources requires substantial upgrades and sophisticated management. Key issues include:

• Grid Congestion: Many of the windiest locations, ideal for onshore wind development, are often remote from major demand centres and existing transmission infrastructure, leading to bottlenecks and grid congestion.
• System Balancing: Matching supply and demand in real-time becomes more complex with high levels of intermittent generation.
• Inertia and System Strength: Traditional synchronous generators (fossil fuels, nuclear) provide ‘inertia’ to the grid, helping to maintain stable frequency. As these are phased out, the grid needs new sources of inertia and system strength from inverters and grid-forming technologies.
• Curtailment: In periods of high wind generation and low demand, or due to grid constraints, wind farms may be asked to ‘curtail’ or switch off, wasting valuable clean energy and incurring compensation costs.

Mitigation Strategies:

1. Grid Reinforcement and Expansion: Major investment in upgrading and expanding the transmission and distribution networks is essential, particularly to connect new renewable energy hubs to demand centres. This includes new overhead lines, underground cables, and substation upgrades (National Grid ESO, 2023).
2. Energy Storage: Deployment of grid-scale battery storage, pumped-hydro storage, and potentially long-duration storage technologies like hydrogen, to store excess renewable energy and release it when needed.
3. Demand-Side Response (DSR): Technologies and policies that incentivise consumers and industries to adjust their electricity consumption in response to supply conditions or price signals, thereby helping to balance the grid.
4. Enhanced Forecasting and Digitalisation: Continued advancements in weather forecasting for wind speeds and electricity demand prediction, coupled with smart grid technologies and artificial intelligence, enable more effective real-time grid management.
5. Hybrid Projects and Interconnectors: Developing hybrid projects that combine wind with solar or storage, and expanding international interconnectors, can help smooth out intermittency over larger geographical areas.
6. System Services Markets: Designing market mechanisms that reward technologies providing grid stability services, such as frequency response, inertia, and voltage control.

6.3. Supply Chain Vulnerabilities and Skills Gaps

The rapid expansion of onshore wind requires a robust and resilient supply chain, encompassing everything from raw materials to skilled labour. Challenges in this area include:

• Global Supply Chain Dependencies: Reliance on international markets for critical components (e.g., rare earth elements for magnets in some generators, specialised steel, manufacturing of large turbine components), which can be vulnerable to geopolitical disruptions or trade wars.
• Manufacturing Capacity: The need for significant domestic manufacturing capacity for turbines and components to reduce import reliance and foster local economic benefits.
• Skills Shortages: A potential deficit of skilled workers in areas such as engineering, project management, construction, and O&M required to deliver the ambitious deployment targets.

Mitigation Strategies:

1. Domestic Industrial Strategy: Developing a strategic industrial policy to encourage UK-based manufacturing of wind turbine components and associated infrastructure, thereby reducing import dependencies and creating green jobs. This may involve targeted investment, R&D support, and procurement policies.
2. Investment in Skills and Training: Implementing comprehensive education, apprenticeship, and retraining programmes to develop the necessary workforce across the entire value chain of the onshore wind sector. Collaborations between academia, industry, and government are crucial.
3. Diversification of Suppliers: Working to diversify sources of raw materials and components to minimise reliance on single countries or companies.
4. Innovation and R&D: Investing in research and development to improve turbine efficiency, material science, and recycling processes, reducing resource intensity and environmental footprint.

By proactively addressing these challenges with integrated policy, technological innovation, and strategic investment, the UK can ensure the continued and effective deployment of onshore wind, maximising its contribution to energy security and the net-zero transition.

7. Long-Term Implications for National Sovereignty and Economic Stability

Many thanks to our sponsor Focus 360 Energy who helped us prepare this research report.

7.1. Strengthening National Sovereignty

Energy independence, largely achieved through domestic renewable energy production like onshore wind, is inextricably linked to and fundamentally reinforces national sovereignty. A nation’s ability to generate a significant proportion of its energy from indigenous resources lessens its vulnerability to external political pressures, economic coercion, and unpredictable supply chain disruptions from foreign entities or states. This empowers the UK to exercise greater autonomy in its energy policy and, by extension, its broader foreign policy and national security decisions.

When a country relies heavily on imported energy, particularly from a limited number of suppliers, it can become susceptible to the ‘energy weapon’ – the use of energy supply as a tool of political leverage. The events of 2022, following Russia’s invasion of Ukraine, starkly illustrated how gas supplies could be manipulated for geopolitical ends, profoundly affecting European nations heavily dependent on Russian energy. By developing a robust domestic energy base through onshore wind, the UK dramatically reduces its exposure to such risks. It means that the cost of electricity is largely determined by internal investment and operational costs rather than fluctuating international commodity markets or the whims of geopolitical actors (Slaughter and May, 2022).

Furthermore, leadership in renewable energy technology and deployment enhances a nation’s ‘soft power’ and geopolitical influence. By demonstrating a credible path to decarbonisation and energy security through innovative domestic solutions, the UK can inspire and collaborate with other nations, influencing international energy norms and climate action. This positions the UK as a responsible and resilient global actor, capable of charting its own energy destiny and pursuing its national interests without the shadow of energy insecurity looming over its strategic choices. True energy sovereignty is not merely about physical supply but about the freedom to choose one’s path unencumbered by external energy dependencies.

Many thanks to our sponsor Focus 360 Energy who helped us prepare this research report.

7.2. Economic Stability and Growth

The expansion of onshore wind capacity contributes profoundly to the UK’s long-term economic stability and fosters sustainable growth across multiple sectors. One of the most significant contributions is to price stability. Unlike fossil fuels, whose prices are subject to volatile global markets, exchange rate fluctuations, and geopolitical events, the operating costs of onshore wind farms are largely fixed once built. This offers a stable, predictable cost base for electricity generation, insulating businesses and consumers from the severe price shocks witnessed in recent years (Energy UK, 2022a). Such predictability is invaluable for industrial planning, household budgeting, and overall macroeconomic stability.

The renewable energy sector, with onshore wind at its vanguard, acts as a powerful engine for economic growth. It stimulates significant capital investment, both domestic and foreign direct investment, into the UK’s infrastructure and technology sectors. This investment translates into increased Gross Value Added (GVA) for the UK economy, particularly in regional areas hosting wind projects (RenewableUK, 2023). As discussed, it generates thousands of high-quality jobs across the project lifecycle – from R&D and manufacturing to construction and long-term O&M – creating a skilled workforce and fostering regional economic regeneration.

Moreover, the development of a strong domestic renewable energy industry encourages technological innovation. Research and development in turbine design, grid integration, and energy storage technologies not only improve the efficiency and cost-effectiveness of wind power but can also create intellectual property and export opportunities for UK expertise and products globally. This positions the UK at the forefront of the global green economy, attracting further investment and talent (DESNZ, 2025b). The transition to a clean energy system is increasingly viewed not just as an environmental imperative but as a tremendous economic opportunity for job creation, industrial growth, and long-term prosperity. By investing in onshore wind, the UK is not simply securing its energy supply; it is building a resilient, innovative, and sustainable economic future that is less susceptible to external shocks and better positioned to thrive in a decarbonising world.

8. Conclusion

The rigorous integration and ambitious expansion of onshore wind are not merely incidental but are pivotal, foundational components of the United Kingdom’s overarching strategy to enhance its national energy security. This report has meticulously demonstrated that by leveraging this mature, cost-effective, and domestically available technology, the UK can fundamentally transform its energy landscape, moving decisively away from the vulnerabilities associated with a historical reliance on imported fossil fuels.

The strategic value of onshore wind is multi-faceted and profound. Geopolitically, it acts as a powerful bulwark against the inherent unpredictability and volatility of international energy markets, diminishing the UK’s exposure to external supply disruptions and the potential for energy weaponisation. Economically, onshore wind offers significant cost competitiveness, delivering some of the cheapest forms of new electricity generation and providing long-term price stability for consumers and industries. Crucially, its development fuels substantial job creation, attracts vital investment, and stimulates local economies, contributing to a robust and sustainable economic growth trajectory. Strategically, its integration mandates and accelerates crucial grid modernisation efforts and complements robust energy diplomacy, creating a more resilient and interconnected national energy infrastructure.

Beyond these immediate benefits, the commitment to onshore wind has profound long-term implications for the UK’s national sovereignty and economic stability. It fosters genuine energy independence, empowering the nation to chart an autonomous course in its energy policy and broader geopolitical engagements. The burgeoning green economy, spearheaded by renewable technologies like onshore wind, positions the UK as a leader in the global energy transition, attracting talent, driving innovation, and securing a sustainable economic future.

In conclusion, the UK’s steadfast commitment to onshore wind is more than an environmental imperative; it is a strategic national security imperative. It represents a pragmatic and powerful mechanism not only to address immediate energy security concerns and mitigate the impacts of global market fluctuations but also to lay an enduring foundation for a resilient, independent, prosperous, and decarbonised future. The ‘onshore wind revolution,’ as envisioned by the government, is thus an indispensable pillar in constructing a secure and sustainable energy destiny for the United Kingdom.
