The International Energy Agency (IEA) has highlighted significant changes in the world's electricity market, particularly in the context of decarbonization and evolving consumption patterns. According to the IEA's 2024 report on electricity consumption forecasts through 2026, the power generation sector is leading the transition to net-zero emissions. Despite being the largest source of carbon dioxide (CO2) emissions, the power generation industry is actively contributing to the global shift toward renewable energy, which is expected to become the primary source of electricity by 2025.
The IEA report anticipates a decline in consumption growth from 2.4% in 2022 to 2.2% in 2023, followed by an increase to 3.4% in 2026. Key contributors to this growth are expected to be China and India. However, the report also points out a significant surge in energy consumption by data centers, artificial intelligence (AI), and cryptocurrencies. This sector is projected to more than double, surpassing 1,000 terawatt hours (TWh) by 2026. The United States hosts one-third of all data center types, and AI power consumption is predicted to increase tenfold between 2023 and 2026, with technologies like ChatGPT alone consuming nearly 10 TWh per year during this period.
While the overall energy consumption landscape is evolving, concerns are raised about the increasing energy use associated with cryptocurrencies. The IEA report highlights that cryptocurrency mining, which consumed 130 TWh in 2023 (up from 110 TWh in 2022), could reach 160 TWh by 2026. Although cryptocurrency mining represents a relatively small fraction of global energy consumption, it remains a source of concern for its potential impact on electricity consumption. The report emphasizes the challenge of reducing electricity consumption, as energy savings in some areas may be offset by increases in other energy-consuming operations, including various cryptocurrencies.
Despite the concerns, Bitcoin mining is reported to use 54.5% sustainable energy. The ongoing Bitcoin halving has led to increased mining activity, with miners making substantial investments in new equipment. The dynamic landscape of changing energy consumption patterns underscores the need for continued vigilance and efficiency improvements across various industries.
