Renewable energy has crossed a historic milestone in the global energy transition. In 2024, renewables generated over 30 per cent of the global electricity output, overtaking coal, which accounted for 26 per cent. The shift has been driven by extraordinary cost declines—solar photovoltaic (PV) costs have fallen by 85 per cent, and onshore wind by 55 per cent over the past decade—transforming clean energy from a niche technology into the backbone of modern power systems. Many major economies now generate more electricity from renewables than from coal, a symbol of how far the world has come.
Yet this achievement comes at a moment of extraordinary complexity. As countries expand their renewable capacity, the world is also entering an era of rapid economic and digital growth that will significantly increase electricity demand. Global GDP is projected to grow at 3–3.5 per cent annually, driven by industrialisation, urbanisation, and shifting consumption patterns. At the same time, the digital economy—data centres, cloud computing, AI model training, and high-performance computing—is emerging as one of the fastest-growing electricity consumers.
Data centres already consume around 2 per cent of global electricity, and this could rise to 8–10 per cent by 2030 as AI training accelerates. A single frontier-model AI training run now consumes as much electricity as 5,000 households do in a year. These new electricity loads, if not met with clean power, could force countries to rely on coal and gas, reversing hard-won climate gains.
This article assesses the economic and technological drivers behind renewable growth, maps the rising electricity footprint of digital and AI-led development, and outlines global and region-specific pathways to ensure that future demand is met through clean, resilient, and climate-aligned power systems.
1. The Economic Drivers Behind the Renewable Energy Boom
The growth of renewables over the past decade is the result of reinforcing market, technological, and policy dynamics.
Cost Declines Have Reshaped the Global Power Market
The steep fall in clean-energy prices is the single largest driver of the transition.
- Solar PV costs are down 85 per cent since 2010
- Onshore wind costs have fallen 55 per cent
- Battery storage costs have decreased nearly 80 per cent
Utility-scale solar and wind are now the cheapest sources of new electricity in most major markets. These reductions were enabled by supply-chain scaling, Chinese manufacturing dominance, improved turbine designs, higher solar efficiencies, and enhanced project execution.
In 2023, global clean-energy investments surpassed USD 1.7 trillion, outpacing fossil fuel investments by a wide margin. Solar alone attracted more capital than upstream oil and gas, reflecting investor confidence in the long-term trajectory of clean-energy systems.
Energy Security Has Become a Strategic Priority
The geopolitical shocks of recent years—especially the Russia-Ukraine conflict—have driven home the risks of fossil fuel dependence. Countries across Europe, Asia, and the Indo-Pacific are pivoting towards renewables not only for climate reasons, but to enhance energy independence, insulate their economies from volatile fuel prices, and secure long-term supply.
Corporate Procurement Is Accelerating the Transition
Companies represent one of the strongest demand signals for renewable energy. More than 450 global corporations have committed to sourcing 100% renewable electricity. Technology giants—Google, Microsoft, Amazon, Meta—are now among the world’s largest renewable PPA buyers, shaping grid investments in the U.S., the EU, and Asia. Their data centres increasingly seek to operate on round-the-clock clean power, pushing utilities to diversify their resource mixes and invest in storage.
2. Digitalisation, AI, and the New Electricity Super-Cycle
Even as renewables grow, global electricity demand is entering a period of unprecedented acceleration. As global GDP expands by 3–3.5 per cent annually, electricity consumption will rise sharply, particularly in emerging markets. Middle-income countries transitioning into manufacturing and services sectors—India, Indonesia, Vietnam, Nigeria, and Brazil—will experience the fastest growth.
Data Centres Are the New Industrial Load
Data centres are becoming what steel mills and aluminium smelters were for the past century.
- Today, they consume 2% per cent of global electricity
- By 2030, this may reach 8–10 per cent, depending on AI expansion
- In Ireland, data centres already account for 18 per cent of national electricity consumption
Hyperscale cloud zones in the U.S., the EU, China, and India are driving enormous local demand surges, stressing grid infrastructure and increasing the risk of fossil-fuel fallback.
AI Model Training Is an Energy-Intensive Frontier
Training large AI models is incredibly power-intensive. Frontier models require tens of thousands of highly specialised GPUs operating for weeks or months.
A single training run for a cutting-edge AI model consumes electricity equivalent to 5,000+ households annually.
As AI becomes embedded in search engines, logistics, customer services, scientific modelling, and healthcare, the energy demand for inference—the day-to-day operation of AI models—will multiply rapidly.
The Grid Is Becoming the Bottleneck of the Digital Revolution
Countries are racing to become digital and AI hubs, yet grid capacity expansion is lagging.
- Singapore has paused new data-centre approvals
- The U.S. has a backlog of thousands of gigawatts of renewables waiting for grid interconnection
- Europe faces cross-border congestion that hampers renewable balancing
- India’s digital corridors are facing transformer and distribution constraints
Without accelerated investments in transmission and storage, countries may meet new loads with coal and gas, jeopardising climate goals.
3. Regional Dynamics: How India, China, and Africa Are Shaping the Next Phase
India: High Growth, High Demand, High Ambition
India is both a leader and a test case for managing rapid economic growth while expanding clean power. GDP is expected to grow at 6–7 per cent annually, driven by industrialisation, urbanisation, and a national push to become a global manufacturing and digital hub.
Electricity demand could double by 2030, fuelled by:
- Semiconductor fabs
- Green hydrogen manufacturing
- Urban metro expansions
- EV deployment
- Cloud and AI infrastructure
India’s data-centre electricity consumption could rise from under 1% today to 3–4 per cent by 2030, with Mumbai, Chennai, Hyderabad, and Noida emerging as hyperscale hubs.
India has set a target of 500 GW of non-fossil capacity by 2030, backed by the world’s largest solar park programme and a significant push for pumped hydro and battery storage. Yet transmission expansion, financial reforms in power utilities, and land acquisition remain challenges. Coal remains a fallback during peak demand spikes.
The coming decade will determine whether India becomes a global model for clean industrial growth—or faces grid stress and fossil resurgence.
China: The World’s Renewable Giant Facing a Digital Power Crunch
China leads the world in renewable deployment by an enormous margin. In 2024, it installed more solar than the rest of the world combined. Several provinces now generate more electricity from wind and solar than from coal.
Yet China’s electricity system is under immense pressure:
- AI, cloud computing, and quantum research are driving massive demand
- Coastal consumption hubs suffer from grid congestion and intermittency
- Droughts have disrupted hydro-heavy regions like Sichuan
- Heavy industry, though moderating, still requires substantial baseload power
China’s strategy includes:
- Ultra-high-voltage (UHV) transmission lines
- Massive battery installation targets
- Long-duration energy storage pilots
- A “green computing” strategy
- Renewable-powered data centre clusters in Inner Mongolia and Gansu
China’s success or failure in synchronising energy and digital industrial policy will shape global climate trajectories.
Africa: Massive Renewable Potential at a Critical Development Threshold
Africa has some of the world’s best renewable resources, yet some of the lowest access levels. Over 600 million people still lack reliable electricity. However, the continent is entering a phase of digital transformation—expanding mobile services, cloud infrastructure, fintech, e-health, and digital public services.
Electricity demand in Africa could triple by 2040, yet grid capacity lags behind.
Data-centre expansion is rising sharply, with the number of operational facilities expected to double by 2030. Without intervention, these loads may be served by diesel generators or gas plants. Still, Africa holds enormous promise. While Morocco and Egypt lead in solar and wind, Kenya is a geothermal pioneer. On the other hand, Namibia and South Africa are emerging green-hydrogen hubs. Mobilising concessional finance, de-risking investments, and strengthening grids will be key to helping Africa leapfrog to a clean-energy future.
4. The Risk of Backsliding: Fossil Fuels Could Fill the Gap
Despite the exponential rise of renewables, the world faces a real risk of fossil resurgence.
- Electricity demand is growing faster than renewable capacity additions
- Coal plant life extensions are becoming politically attractive in South and Southeast Asia
- Natural gas is making a comeback as a “transition fuel”
- Heatwaves and droughts are testing renewable reliability
Unless the world scales renewables, transmission, and storage at unprecedented speed, fossil-fuel fallback will undermine climate ambitions
5. Pathways to Building Clean, Resilient, and Future-Ready Power Systems
The world needs to install renewables at 3–4 times of today’s pace to stay on track for climate targets. Furthermore, over 80 million km of transmission and distribution lines must be built or modernised by 2040. An estimated 600 GW of storage is needed globally by 2030. Governments must require data centres and AI clusters to procure renewable power and invest in efficiency.
Conclusion: A Tipping Point — With New Risks and New Opportunities
The rise of renewable energy marks a turning point in global development. But the next decade will determine whether clean energy becomes the backbone of the world’s economic and digital future—or whether fossil fuels stage a comeback.
The stakes are high. Electricity demand from GDP growth, digitalisation, and AI will surge. Renewables, storage, grids, and policies must evolve even faster. The decisions made now—by governments, tech companies, investors, and multilateral institutions—will shape the world’s energy, climate, and economic future for generations.
