The Reality of Rising Energy Demand

Energy demand is rising because of several structural forces converging at the same time: population growth, urbanisation, digitisation, electrification, rising living standards, geopolitical realignment, and climate volatility. Despite laudable improvements in energy efficiency, the result of a multi-polar growth scale is clear: the world needs more electricity, and more flexibility in how that electricity is managed.

So far this decade, energy demand is growing at high levels. Global energy demand grew by 2.2% in 2024, significantly above the average annual increase of 1.3% between 2013 and 2023. Electricity demand, a key driver of total energy use, rose by 4.3% in 2024, almost twice as fast as overall energy growth, and significantly ahead of global GDP growth.

The International Energy Agency (IEA) reports that global electric power demand is entering what it calls the “Age of Electricity.”

• Global electricity demand is on track to grow more than 3.5% per year on average through the rest of this decade — a pace historically unprecedented.
  

• Peak electricity demand alone is projected to rise by around 40% by 2035 under typical policy scenarios.

This reflects an accelerating shift to electrification in transport, buildings and industry, as well as rapid growth of data centres and cooling load from rising temperatures.

The IEA’s flagship World Energy Outlook 2025 ndicates that:

• Peak electricity demand could increase ~40% by 2035 under current policy scenarios.

  
  

• Total electricity generation is expected to expand significantly as countries decarbonise their power sectors.

Under scenarios aligned with European Union climate goals like Net Zero by 2050, electricity’s share of final energy consumption is projected to rise dramatically:

Electricity could grow from about 20% of total final energy consumption today to over 50% by 2050, driven by electrification of transport, heating and industry.

This isn’t just a shift in fuel mix, it’s a massive scaling of total electricity demand.

What are the major sources of rising electricity demand?

1. Population Growth: The Base Layer of Demand

The global population now stands at approximately 8.2 billion people and continues to rise. Even where growth rates slow, total energy demand increases because billions of people are moving into higher-consumption lifestyles.

Energy demand is not linear with population: it is exponential with development.

As nations industrialize:

• Electricity access expands

• Appliance ownership increases

• Transport electrifies

• Industrial production scales

• Digital infrastructure expands

Per capita electricity consumption in developed economies is often 5–10 times higher than in developing ones. As emerging markets grow, energy intensity follows.

2. Urbanization and Rising Living Standards

Urbanisation is one of the most powerful drivers of electricity demand. Today, over half the world’s population lives in cities. By mid-century, that figure is projected to approach 70%.

Urban environments require:

• High-rise construction

• HVAC systems

• Water pumping

• Lighting

• Mass transit

• Telecommunications infrastructure

Two of the most significant and predictable contributors to energy demand are air conditioning and refrigeration. As temperatures rise and incomes increase, cooling demand surges. Air conditioning alone is expected to become one of the largest sources of electricity growth globally.

In warmer regions, including Southern Europe, the Middle East, and Asia, summer peak loads are increasingly defined by cooling demand. This creates sharp, seasonal spikes in grid stress.

Electricity systems must now handle higher peaks, not just higher annual consumption.

3. The Explosion of AI and Cloud Infrastructure

The digital economy is no longer lightweight.

Artificial intelligence, machine learning, blockchain infrastructure, and hyperscale cloud computing have dramatically increased electricity consumption in data centres.

Modern AI training clusters require:

• High-density GPU servers

• Continuous cooling

• Redundant power systems

• 24/7 operation

Data centres are becoming energy-intensive industrial facilities. Major technology firms are now directly contracting renewable power plants and even investing in nuclear power to secure supply. This is not branding: it is survival.

Electricity demand from data centres is projected to grow substantially over the next decade, especially in North America and Europe. Unlike residential demand, data centre loads are continuous and highly sensitive to outages. They require both reliable supply and power quality stability.

4. Electrification of Transport and Industry

The energy transition itself increases electricity demand. As countries electrify passenger vehicles, commercial fleets, heat pumps and industrial processes, electricity replaces fossil fuels.

While total primary energy demand may stabilise over time, electricity demand rises sharply during the transition.

Electric vehicle charging alone introduces new peak load patterns, especially when charging is not intelligently managed. The system must not only generate higher electricity output, but it must align the areas of electricity generation and consumption through intelligent distribution grids. This remains a major challenge in Europe, for example, where certain areas of farmland are being turned over to renewable energy production, but are separated from high energy demand areas by hundreds of kilometers, necessitating massive distribution investments.

5. Europe: Geopolitical Disruption and Energy Realignment

Europe’s energy system experienced a structural shock following the disruption of Russian oil and natural gas supplies. This triggered:

• Rapid diversification of gas supply

• Acceleration of LNG imports (from non-Russian sources)

• Increased investment in renewables

• Emergency demand-reduction policies

Simultaneously, the European Union has committed to achieving Net Zero carbon dioxide emissions by 2050. This means:

• Coal phase-out

• Reduced gas dependency

• Massive renewable expansion

• Electrification of heating and transport

Renewable generation, in particular wind and solar, has grown significantly. However, these sources are inherently intermittent. Wind depends on atmospheric conditions. Solar depends on daylight and weather. Their variability introduces supply volatility into the grid.

As fossil baseload plants retire, system flexibility and intelligent grids become critical.

6. Climate Change and Weather Volatility

Energy systems are increasingly exposed to climate-related stress:

• Heatwaves increasing cooling demand

• Flash floods damaging infrastructure

• Wildfires disrupting transmission lines

• Extreme rainfall events

• Storm-driven outages

Climate volatility affects both supply and demand simultaneously. For example:

• High temperatures reduce transmission efficiency

• Drought reduces hydroelectric output

• Wind droughts reduce turbine production

• Heat increases electricity demand

This dual stress creates instability in traditional grid models. The system must now be resilient to both demand spikes and generation variability.

7. The Core Problem: Production Alone Is Not Enough

Historically, energy systems were built around predictable baseload generation based on carbon-based feedstocks such as Coal and Gas, as well as Nuclear energy. Supply could be ramped in a controlled way.

Today’s energy production mix and distribution system is different:

• Variable renewable input

• Electrified transport

• Digital infrastructure loads

• Climate-driven peak demand

• Decentralised generation split between public and private generation sources

Building more generation capacity alone does not solve this challenge. The real requirement is flexibility.

8. Why Energy Storage Is Central to the Solution

Energy storage solves three systemic problems:

1. Balancing Intermittency

It stores surplus renewable generation when production is high and releases it when production falls.

2. Managing Peak Demand

It reduces stress during demand spikes, particularly from cooling and EV charging.

3. Strengthening Resilience

It provides backup during outages and grid instability. Without storage, renewable penetration is constrained; grid stability deteriorates, price volatility increases and infrastructure investment costs rise. With storage:

• Renewable utilisation increases

• Transmission congestion is reduced

• Energy price arbitrage becomes possible

• Carbon reduction becomes more practical

Storage is no longer an optional support technology: it is enabling infrastructure which remains applicable to the household, corporate and regional levels of administration and investment.

Conclusion: The Energy System is becoming more complex

Global electricity demand is rising due to:

• Population growth

• Urbanisation

• AI and data infrastructure

• Electrification of transport

• Rising living standards

• Geopolitical realignment

• Climate-driven volatility

At the same time, generation is shifting toward intermittent renewable sources. This combination creates a simple reality:

The future energy system requires not only more production, but intelligent storage and management.

Energy storage is the bridge between volatility and stability. It transforms energy from a real-time commodity into a controllable asset. And in an increasingly uncertain world, ensuring this level of security and control is a strategic asset of vital importance.
