Executive Summary
The renewable energy sector moves through 2026 at a pivotal moment. Renewables overtook coal as the world’s largest source of electricity in 2025 for the first time in over a century, yet the path forward is defined as much by complexity as by opportunity.
AI is reshaping demand on two fronts: driving extraordinary growth in electricity consumption through data centre proliferation, whilst simultaneously enabling smarter grid management and efficiency gains.
Capital remains available, but geopolitical disruption, policy shifts, and rising financing costs are forcing greater discipline, with investors gravitating towards resilient, scalable platforms over growth at any cost.
Digital transformation has moved from pilot to core operations, supply chain resilience has become a strategic priority, and sustainable fuels are gaining importance for sectors that cannot be electrified.
Across all of these dynamics, one factor emerges consistently as the differentiator: leadership capability. Organisations that secure executives combining technical depth with commercial acumen, digital literacy, and the ability to navigate complex regulatory environments will be best positioned to lead the transition.
The renewable energy sector continues to confront a complex landscape shaped by surging electricity demand, rapid artificial intelligence integration, and persistent supply chain challenges. Whilst global renewable capacity continues to expand at unprecedented levels, organisations must still navigate market volatility, regulatory shifts, and infrastructure constraints as they position themselves for the next phase of the energy transition.
AI and Electrification: Driving Unprecedented Power Demand
Artificial intelligence isn’t merely consuming more energy; it’s fundamentally reshaping demand patterns across the renewable energy industry. According to Deloitte’s 2026 Energy Industry Outlook, peak power demand could surge by 26% by 2035, propelled by the rapid growth of data centres and electrification. Global electricity demand grew by 3% in 2025, and the IEA now projects an average annual growth rate of 3.6% through 2030 – around 50% higher than the previous decade’s average – driven by industrial activity, air conditioning usage, and the proliferation of data centres. Investment in AI and data centres continues to accelerate dramatically, with major technology companies committing USD 320 billion in 2025, up from USD 230 billion the previous year. Data centre electricity demand alone is projected to increase by approximately 240 TWh relative to 2024 levels through 2030.
Yet AI also presents solutions to the strains it creates. Utilities are employing artificial intelligence to forecast demand, balance loads, and strengthen grid resilience in real time. The result is an emerging, interconnected energy ecosystem where intelligence itself becomes a virtual supply of power through enhanced efficiency and operational flexibility.
Key Insight: The renewable energy industry is experiencing a dual transformation. Whilst AI-driven data centres contribute to unprecedented electricity demand growth, these same technologies are simultaneously enabling smarter grid management and operational optimisation. This paradox defines the current renewable energy market landscape: technology is both the challenge and the solution. Companies that successfully harness AI for efficiency gains whilst managing its energy footprint will gain significant competitive advantages in the evolving green energy industry.
Market Volatility and Capital Discipline: The New Reality for Renewable Energy
The renewable energy industry is entering a phase characterised by abundant investment capital, but with a sharpened focus on stability, scalability, and disciplined returns. Tariffs, policy fluctuations, and rising financing costs are compelling companies to fundamentally reassess their investment strategies, scrutinising every pound of expenditure whilst measuring resilience as carefully as growth potential.
Recent geopolitical events have brought this volatility into sharp focus, with major energy transit routes disrupted and oil prices experiencing extreme swings within single trading sessions – a vivid reminder of how quickly instability can cascade through global energy markets.
Power and renewable companies face compressed timelines and heightened compliance requirements following legislative changes affecting clean energy provisions. The sector must navigate these regulatory shifts whilst managing rising operational costs and market uncertainties that challenge profitability. In response, developers are prioritising efficiency improvements, with investors gravitating towards mature assets, scalable platforms, and hybrid portfolios capable of delivering reliable returns and strategic optionality.
For leadership across the renewable energy industry, the critical question has shifted. It’s no longer simply whether to invest, but rather where efficiency and innovation can generate the most substantial impact. This refined approach to capital allocation reflects a maturing industry that recognises sustainable growth requires both ambition and prudence.
Renewable Expansion: Progress Amidst Persistent Challenges
2025 marked a landmark moment for the global energy transition. For the first time in over a century, renewables overtook coal as the largest source of electricity worldwide, reaching a 33.8% share of global generation. Solar was the defining force: global solar generation rose by 636 TWh — the largest increase of any power source on record — meeting three-quarters of global electricity demand growth for the year. Looking ahead, both solar and wind are expected to overtake nuclear in 2026, underscoring the pace at which the generation mix continues to shift.
However, structural challenges persist in integration and storage, limiting the full utilisation of renewable capacity. Countries like Brazil, which maintains an electricity matrix with more than 80% renewable sources, face growing curtailment issues. This reflects limitations in:
- transmission infrastructure
- system operation capabilities
- storage mechanisms at scale.
These obstacles must be overcome to increase renewable utilisation and prevent the wastage of clean energy generation.
Through 2026 and beyond, these trends are expected to intensify, with greater deployment of battery storage, new transmission lines, and regulatory adjustments aimed at creating more flexible electrical systems. Important auctions for transmission projects and capacity are forecast, representing substantial volumes of registered projects. These initiatives should expand infrastructure, reinforce security of supply, and facilitate integration of additional renewable sources, reducing the need for scheduled generation cuts during periods of high production.
GLOBAL PERSPECTIVES: REGIONAL RENEWABLE ENERGY INSIGHTS
Whilst the direction of the global energy transition is clear, the pace, priorities, and challenges shaping renewable energy markets continue to vary significantly by region.
Across global markets, organisations are balancing infrastructure investment, regulatory change, energy security, supply chain pressures, and decarbonisation targets, whilst responding to rising electricity demand and increasing operational complexity.
These dynamics are reshaping leadership requirements across the sector. Investors, developers, utilities, and infrastructure operators increasingly require executives who can combine technical expertise, commercial acumen, and the ability to navigate evolving market conditions.

France: Policy, Capital and Energy Transition By Edouard Crédey | Partner Horton International France
The current trend in France is strongly shaped by political decision-making. Public, industrial and local stakeholders disagree over the energy mix to be prioritized, while nuclear power is once again at the center of the debate. The development of renewables depends on the alignment of a complex ecosystem — the state, industrial players, local authorities, grid operators and investors — whose interests may diverge, unlike the major historical infrastructures that were largely driven by public authorities. The future trajectory will likely rely on a combination of state leadership, regulatory stability and the significant mobilization of private capital.
These constant changes require stakeholders to remain continuously agile and to mobilize the right talents.
Europe & Middle East: From Vision to Delivery By Daniel Greiner, Principal, Horton International Germany
Across Oil & Gas and Aviation, the energy transition in 2026 is becoming far more execution-focused. In both Europe and the Middle East, investment appetite remains strong across renewables, grid infrastructure, storage and digital energy solutions, but the conversation has clearly shifted from vision to delivery, capital discipline and resilience.
In Oil & Gas, the most forward-looking players are broadening their portfolios across lower-carbon businesses, power, hydrogen and carbon management, while still recognising that energy security and industrial reliability remain non-negotiable. In aviation, sustainable aviation fuel is now firmly on the strategic agenda, but scaling supply, improving commercial viability and building the right cross-industry partnerships will determine who leads and who follows. What stands out most is the leadership requirement this creates. Companies increasingly need executives who can operate across traditional energy, infrastructure, technology and decarbonisation agendas at the same time. AI, automation and data are no longer side topics; they are becoming central to planning, asset optimisation and competitiveness. The winners will be those who combine ambition with speed, execution and leadership depth.
