Introduction
According to the International Energy Agency (IEA), global electricity demand is expected to grow by 4% in 2025, continuing the trend from 2024. This marks the fastest rate of increase in nearly two decades, driven by prominent economic activity, widespread adoption of electric vehicles (EVs), heat pumps, and increased cooling needs due to extreme weather conditions. The growth in electricity demand highlights the critical role of electricity in energy systems worldwide and the need for a substantial increase in renewable energy capacity to meet this demand sustainably.

Rising Global Electricity Demand
The electricity surge is largely driven by rapid industrialization and population growth in emerging economies like India and China. India is expected to see an 8% rise in electricity demand, primarily due to continued economic expansion and the increased use of air conditioning during prolonged heatwaves. Similarly, China’s electricity consumption is anticipated to grow by more than 6%, fueled by intense manufacturing and service activity.
In contrast, the United States is forecasted to experience a more moderate increase of 3% in electricity demand in 2025. This growth is followed by the ongoing electrification of the transportation and building sectors and the increasing power requirements of data centers. Meanwhile, the European Union is expected to see a modest recovery, with demand growth projected at 1.7%, as the region continues to recover from the energy crisis and economic slowdown of previous years.
Expansion of Renewable Energy
Significant advancements in renewable energy parallel the rapid growth in electricity demand. By 2025, renewable sources are expected to contribute 35% of global electricity generation, up from 30% in 2023. Solar photovoltaics (PVs) energy is anticipated to meet half the global electricity demand growth, with solar and wind combined covering nearly three-quarters of the increase. This substantial growth is attributed to declining technology costs, supportive government policies, and the urgent need to reduce greenhouse gas emissions.
Despite this progress, the share of coal in global electricity generation will likely remain stable in 2025 due to the high demand for reliable power, particularly in Asian countries like China and India. However, renewable energy is expected to generate more electricity globally than nuclear and coal based electricity, marking a significant milestone in the global energy transition.
Energy Security and Fossil Fuel Dynamics
In 2025, energy security concerns will continue to influence global energy as the transition to renewable energy accelerates. The strong growth in electricity demand, especially in Asia, is expected to increase reliance on fossil fuels in some regions to meet peak power requirements. For example, in the United States, natural gas is projected to maintain its share of power generation at 39%, slightly down from 42% in 2024, as renewable output rises to meet the growing demand.
The IEA emphasizes the importance of strengthening grid infrastructure and enhancing energy storage capabilities to ensure a stable and reliable electricity supply as the share of renewables increases. These investments are crucial to preventing disruptions and ensuring that renewable energy can effectively replace fossil fuels without compromising energy security.
Technological Innovations and Energy Efficiency
Technological advancements in energy storage and smart grid management will play a crucial role in 2025, enabling the integration of variable renewable energy sources like solar and wind into the grid. Innovations such as advanced battery storage systems, smart meters, and demand response technologies are essential for managing peak loads and maintaining grid stability. These technologies will also help reduce energy consumption during peak periods, improving overall energy efficiency and minimizing the environmental impact of increased electricity demand.
Conclusion
The global energy outlook 2025 indicates a sharp rise in electricity demand, driven by economic growth and increased electrification across various sectors. Renewable energy, particularly solar PV, is set to meet a substantial portion of this demand, marking a significant step towards a sustainable energy future. However, to fully capitalize on the potential of renewables and ensure energy security, significant investments in grid infrastructure, energy storage, and energy efficiency are necessary. The success of the global energy transition will depend on the ability of countries to navigate these changes and implement the necessary policies and technologies to support a resilient and sustainable energy system.
