Cybersecurity Challenges in the Energy Sector

The energy sector faces cybersecurity challenges amid rising electrification and digitalisation. A recent report from the International Energy Agency (IEA) marks the increasing energy demands of data centres, driven largely by artificial intelligence (AI). By 2030, data centres are projected to consume approximately 945 terawatt-hours (TWh) of electricity, surpassing Japan’s total energy needs. This surge in energy consumption poses risks not only to energy security but also to the integrity of energy systems.

Current Energy Consumption Trends

In 2024, data centres consumed about 415 TWh, accounting for 1.5 per cent of global electricity use. This demand has escalated at a rate of 12 per cent annually over the past five years. The majority of this growth is attributed to AI, which requires substantial computational resources. Data centres house servers, storage systems, and networking equipment, with servers alone consuming around 60 per cent of the total energy.

Sources of Electricity for Data Centres

Coal remains the dominant source of electricity for data centres, contributing 30 per cent of the total. Renewables follow closely at 27 per cent, while natural gas and nuclear energy supply 26 per cent and 15 per cent, respectively. Future projections suggest that renewables will meet nearly half of the increased energy demand, with natural gas and coal also playing roles.

Emergence of Small Modular Reactors

Small Modular Reactors (SMRs) are expected to enter the energy landscape post-2030. These advanced nuclear reactors can provide up to 300 megawatt-equivalent (MW(e)) per unit. The introduction of SMRs aims to enhance efficiency and reduce reliance on fossil fuels during energy production. Technology companies are already planning to invest in over 20 gigawatts (GW) of SMR capacity.

Cybersecurity and Energy Security Concerns

As the energy sector becomes more interconnected, cybersecurity issues grow. The reliance on critical minerals for data centre construction, particularly gallium, poses vulnerabilities. China controls 95 per cent of gallium refining, creating risks of supply disruptions due to geopolitical tensions or natural disasters. By 2030, the demand for gallium from data centres could reach 10 per cent of current supply levels.

AI’s Dual Role in Energy Consumption

AI presents an energy paradox. While it increases energy demand, it also has the potential to optimise energy systems and reduce emissions. AI can improve the efficiency of electricity grids and accelerate the development of renewable energy technologies. The challenge lies in integrating environmental considerations into AI development to ensure that its applications provide real value to society.

Future Outlook

The future of the energy sector will depend on how stakeholders manage the balance between growing energy demands and the need for sustainable practices. Policymakers, companies, and societies must collaborate to harness AI’s potential while addressing its environmental impact.
