Enabling energy transitions: A policy guide
Introduction
Countries around the world are scaling up their renewable energy ambitions in response to rising climate risks, domestic environmental concerns, fossil-fuel market volatility, and the need for affordable energy. Many have also come to recognise that unlocking renewable energy potential creates new business and industrial development opportunities, alongside expanding low-cost energy access, strengthening energy security, advancing sustainable development and helping achieve climate goals.
Yet, as experience shows, successful deployment depends on more than technological readiness and a clear vision of future opportunities. Critically, it also hinges on the quality, coherence and adaptability of the policies that shape key investment decisions and market acceptance at both the national and subnational levels.
This policy guide presents proven best practices for designing and implementing robust, context-sensitive policy frameworks for renewables, ensuring a transition consistent with broader socio-economic objectives. It offers an overview of energy transition policies across five interrelated policy sets, from strategic planning and financing to maximising renewables, boosting industrial resilience, and ensuring an inclusive transition (see Figure 1, below).
The aim is to facilitate renewable energy deployment and investment decisions for policymakers, regulators, and the public institutions responsible for energy, climate, and development issues, as well as to inform public utilities, development partners, and policy advisors on the specific challenges and opportunities presented by renewables.
Within the five-part guide, the various sections follow a standard format:
- Short descriptions of each policy approach.
- Case studies showing how each policy was enacted in a specific country.
- Further reading for more detailed policy design.
This guide seeks to help recognise policy gaps and identify options based on existing institutional capacity, market structure and development priorities. Rather than prescribing a single policy model, it distils lessons from diverse country experiences, offering a range of policy and design choices to support informed decision-making on renewables anywhere.
A core premise is that energy systems do not operate in isolation. The policy approach and experiences described here have evolved within wider social, economic and environmental systems, up to planet level (see Figure 1). Energy transitions both shape and are shaped by labour markets, industrial development, public finance, trade and investment policy, structure of the energy sector and existing infrastructure. Inevitably, it also reflects each country's resource endowments, geography and demography, economic structure, land-use patterns, social relations and environmental and regulatory frameworks.
Conversely, advances in education and skills development, industrial capabilities, fairly designed trade and investment frameworks, enabling infrastructure, inclusive social policy and sound governance can either enable or, if lacking, constrain the pace and impact of the energy transition. Effective renewable energy uptake, therefore, depends on a “systems perspective,” recognising the energy sector as both a driver and a result of broader socio-economic development. Policymaking to accelerate renewables are most effective when designed with these interdependencies in mind.
Interrelated policy sets
Within the systems perspective, renewable energy policy frameworks can be understood to comprise several interrelated sets of policies. These include deployment policies that incentivise investment and scale-up; integration policies that ensure power systems and end-use sectors can reliably absorb renewables; and structural policies addressing issues like industrial transformation, workforce transitions and local impacts. “Just transition” policies can be vital to support affected workers and communities, manage distributional effects, and maintain political support and social buy-in for ambitious energy transition plans. Weaknesses or inconsistencies in any of these policy domains can undermine implementation and compromise transition outcomes, even where specific instruments appear well designed.
Ownership and governance structures also shape the possibilities for transforming energy systems. Around the world, energy assets range from state-owned and vertically integrated utilities to liberalised markets involving private competitors and diverse communities, with many countries opting for hybrid arrangements combining elements of both. Policy instruments that work well with one kind of ownership structure may be ineffective or counterproductive in another.
Whether renewables are mainly a profit- or an impact-driven investment makes an enormous difference throughout the project cycle. Recognising these differences is essential in adapting proven practices and approaches to unique national and local realities. In all cases, however, consistent policy frameworks aligned around a holistic vision can promote collaborative interactions that maximise wider benefits.
Renewable power generation, for example, can be approached in different ways. Centralising it reduces costs per megawatt, boosts the system operator’s visibility, and facilitates services like frequency and voltage regulation, which help keep the power system stable. Distributed generation, in contrast, increases citizen involvement and awareness. Democratising the power system, in turn, can enhance the government’s social licence for the energy transition, as well as enabling electricity access beyond the reach of the central grid and public utilities.
Renewable-based electricity systems, because of their distributed resource base, tend to be characterised by a wider range of stakeholders compared to fossil fuels and nuclear plants. A system that depends on synergies between solar, wind and other resources in numerous different locations inherently requires deeper social outreach. The transition to renewables, therefore, requires updated procurement practices to ease all the resulting interactions.
Industry policy is a critical complementary pillar of energy transitions. Strategic support for domestic manufacturing, resilient supply chains, and innovation ecosystems can help capture economic gains, strengthen local value creation and support job creation. Aligning industrial, energy and development objectives also helps address uneven regional development and reduce dependency risks. These efforts can be reinforced by trade policy, which shapes how the benefits of the energy transition are distributed across countries. Trade governance can preserve policy space for green industrialisation and strengthen regional value chains, enabling countries to capture greater value from the transition.
Finally, renewable energy policy frameworks must respond to widely differing socio-economic priorities. Countries approach the energy transition from distinct starting points, reflecting different income levels, energy access challenges, industrial structures, labour markets, fiscal conditions, and institutional capacities. For some, renewable energy deployment is closely linked to electrification and development goals; for others, it is bound up with industrial competitiveness, system flexibility or the phase-out of carbon-intensive assets.
Good practices, therefore, are not uniform. Policies must address immediate national and local needs, along with long-term climate and sustainability objectives.
Guide structure
This guide sets out essential policy principles for countries aiming to scale up renewables, combined with real-word examples of good practices and implementation. Its five main parts correspond to different steps and policy objectives:
- Part I: Strategic plans and getting started
Countries can adopt a range of mechanisms to initiate the energy transition, from netzero targets and strategies to renewable energy targets and portfolio standards. This part of the guide also explores tracking mechanisms, financing options to expand energy access, and fossil-fuel phase-out plans, as well as subnational transition plans. - Part II: Financing and pricing the transition
Carbon pricing, tariffs and subsidies can pay for the transition and send proactive price signals, depending on national context. This part highlights derisking tools for developing countries, explores international cooperation options, and outlines guarantees, carbon adjustment schemes, and procurement mechanisms to mobilise capital. It also considers how to regulate the market and target public investments to protect vulnerable consumers. - Part III: Maximising renewable power
Specific policies are needed to maximise renewables on the electricity grid, including reforms to ensure reliable operation with large shares of solar and wind power. This part covers longterm grid planning, grid access and smart grids, distributed generation, and market interactions with prosumers, as well as forecasting, intraday and balancing markets, electricity storage, demand response and other flexibility measures that maintain stability and affordability. - Part IV: Building resilient production, industry and value chains
Policy choices can focus on decarbonising industrial processes, building domestic green value chains, and safeguarding industrial and export competitiveness. This part of the guide addresses localisation strategies, industrial policy and trade tools, border carbon adjustments and powershoring, along with financing and incentives to boost renewables, green hydrogen, biomass, and low-carbon electrification in key sectors and industrial clusters. - Part V: Advancing people-centred transitions
Policymakers also need to consider potential disruptions, how to ensure fairness for workers, and how to safeguard affected communities and vulnerable groups. This part covers planning and permitting, community projects, inclusive siting and assessments, and helpful labour and skills-development measures. It also shows how rural minigrids, offgrid solar solutions, productive energy uses, and clean cooking can all help reduce poverty and inequality.
Ultimately, this policy guide aims to help scale up renewables for a better future. Beyond each country's energy mix, success in the transition means building resilient and environmentally sustainable societies and economies.
