AI adoption is spreading quickly, but its more demanding uses are adding pressure to data-centre power needs; meanwhile, grid capacity, equipment supply chains, and cyber defenses will influence how much of the promised growth can be delivered safely and affordably.
What technology trends will shape 2026?
Several changes are happening at once: AI is moving into more organizations and applications, data centres are consuming more electricity, and energy technologies are being shaped by manufacturing and supply-chain questions as well as installation. Cybersecurity connects these developments because more digital and automated infrastructure creates both new ways to defend systems and new opportunities for attackers.
The figures below describe different kinds of evidence. Stanford HAI’s 2026 AI Index reports on observed developments and adoption; the International Energy Agency’s (IEA) electricity figures combine 2025 estimates with an outlook for 2030. Forecasts are scenarios, not guarantees that every planned data centre or energy project will be built.
AI is spreading, but capability is not the same as reliability
Stanford HAI reports that industry produced more than 90% of notable frontier AI models in 2025 and that organizational AI adoption reached 88%. Its 2026 AI Index also reports that documented AI incidents rose to 362, from 233 in 2024. These figures indicate rapid development and adoption alongside growing concerns about impacts; they do not show that every organization uses AI in the same way or that every model performs reliably.
#1 Best Overall
The Index describes progress across technical benchmarks, research, business, science, medicine, education, and policy, but it also finds performance remains uneven across tasks and that responsible-AI benchmarking is not keeping pace. A strong score on a benchmark should not be treated as proof that a system will be dependable in a different setting.
Generative AI adoption has been unusually fast
Stanford HAI estimates that generative AI reached 53% population adoption within three years, faster than the personal computer or internet did over comparable early periods. This is a global estimate, not a claim that adoption is uniform: the Index reports differences by country and a relationship with GDP per capita.
How will AI affect energy demand?
AI’s electricity footprint is growing, but there is no single useful “energy per prompt” figure. The energy required depends on the task, model, hardware, and how often the service is used. The IEA reports efficiency improvements per task, while also noting growth in more energy-intensive uses such as video generation, reasoning, and agentic systems. Some of these uses can require hundreds or thousands of times more energy per query than simple text generation.
Rank #2
Data-centre electricity use is rising
The IEA estimates global data-centre electricity consumption at about 485 TWh in 2025, following 17% growth that year. Electricity consumption from AI-focused data centres grew 50% in 2025, according to the IEA. In its central outlook, the IEA projects total data-centre consumption to reach roughly 950 TWh in 2030—around 3% of global electricity demand. Those 2030 figures are outlook estimates, not measured outcomes.
The IEA attributes the uncertain outlook to the interaction between efficiency improvements, increasing adoption, and more energy-intensive applications. Efficiency can reduce the electricity required for a given task, but overall use can still rise when more people and organizations run more tasks or shift to more demanding ones.
Investment is expanding alongside demand
The IEA estimates that capital expenditure by the largest technology companies exceeded USD 400 billion in 2025 and expects it to rise by a further 75% in 2026. The 2026 figure is a forecast, not a completed-spending total for the year. The IEA also reports that satellite tracking found AI-factory capacity more than tripled over the preceding 18 months.
What are the biggest renewable-energy and infrastructure challenges?
Renewable energy is part of a wider clean-energy technology system. Solar PV and wind turbines depend on manufacturing capacity, materials, trade, and grid connections; batteries, electric cars, electrolysers, and heat pumps also affect how energy is produced, stored, moved, and used. The IEA’s 2026 Energy Technology Perspectives emphasizes supply-chain resilience and industrial competitiveness alongside deployment. Its reviewed findings do not establish a like-for-like ranking of which technologies will grow fastest in 2026.
Grid readiness can limit data-centre expansion
New data centres need power connections as well as buildings, servers, and financing. In an IEA analysis, grid constraints could delay around 20% of global data-centre capacity planned for construction by 2030. This is a scenario finding about planned capacity globally, not a prediction that one-fifth of every country’s projects will be delayed.
The IEA points to better siting, clearer information about connection queues, and operational flexibility as ways to help manage connection constraints. The broader implication is that data-centre growth, electricity generation, transmission, and local grid planning need to be considered together rather than as separate projects.
Rank #4
Supply chains are part of clean-energy security
Building more renewable generation and other clean-energy equipment requires industrial capacity and supply chains that can withstand disruption. The IEA’s framing includes trade, materials, and manufacturing as well as deployment. That makes affordability and energy security relevant alongside environmental goals: a technology can be promising in use yet difficult to scale if key components or production capacity are constrained.
How is AI changing cybersecurity risks?
AI has two roles in energy cybersecurity. It can help defenders detect threats, analyze activity, and respond faster, but it can also help attackers automate work, develop malicious scripts, conduct reconnaissance, or evade detection. The IEA summarizes this dual use by saying, “AI acts as a force multiplier in both directions, enhancing threat detection and enabling more responsive protection on the one hand while simultaneously empowering adversaries with tools for sophisticated attacks on the other.”
Why energy systems face particular exposure
Energy infrastructure is becoming more electrified, digitalized, and connected. The IEA identifies legacy IT, automation, cloud computing, and third-party vendors as factors that can compound exposure. A connected supply chain means an organization’s security depends not only on its own systems but also on the software, services, and access arrangements on which operations rely.

AI-assisted defense is therefore not a substitute for basic security controls or operational planning. Organizations need to account for how digital tools interact with systems that support energy operations, and how an incident involving a vendor or connected service could affect those systems.

- Separate adoption from dependable performance. Rapid uptake and benchmark gains do not establish that an AI system is suitable for every task; assess it in the context where it will be used.
- Plan power alongside computing. Data-centre proposals depend on generation, grid capacity, and connection timing, not just capital investment and available hardware.
- Track the whole clean-energy system. Deployment depends on manufacturing, materials, trade, storage, and grid infrastructure as well as the installed capacity of solar and wind.
- Prepare for dual-use AI. Use AI-enabled detection and response where appropriate while accounting for attackers’ ability to use similar tools.
- Include legacy and third-party systems in risk planning. Digital modernization does not remove vulnerabilities created by older technology or external dependencies.
Across these areas, the central policy balance identified by the IEA is security, affordability, competitiveness, and environmental goals. Decisions about AI infrastructure and energy technology will be shaped by how well those objectives are reconciled in specific regions and projects.
