Electricity demand is expected to increase far more quickly than overall energy use in the coming decades, according to the latest assessment released by the International Energy Agency (IEA) during climate discussions in Brazil. The report outlines what is changing, when major shifts may occur, where demand is rising most rapidly, and why the trend has become a central global concern. The IEA states that renewable energy, led by solar power, is expanding at record speed, while coal and oil could reach a global peak before 2030. Another scenario, however, indicates that oil and gas demand may continue rising until 2050 due to varied national policies. Strong growth in India, Southeast Asia, Africa, Latin America, and China is shaping global energy patterns. The outlook also warns that around 730 million people still lack electricity and that nearly one-quarter of the global population continues relying on inefficient cooking methods that harm health and the environment.

The analysis explains how countries may respond to these challenges and why stronger action is needed to meet long-term climate goals. The IEA stresses the importance of major investment in power grids, energy storage, and supply chains for critical minerals used in wind turbines, electric vehicles, and solar panels. Rising demand from data centers is also transforming the energy system, with global investment expected to reach $580 billion this year. Energy specialists referenced in the report describe renewable growth as multifaceted, accelerating, pervasive, consequential, and unprecedented, but the outlook also highlights obstacles such as uneven policy support and the risk of surpassing the 1.5°C warming threshold.
