Global investment in energy efficiency reached 0.38 trillion U.S. dollars in 2023, marking a significant commitment to sustainable practices worldwide. This figure represents a slight decrease from the previous year but is projected to grow by nearly 28.9 percent by 2030, based on current and proposed energy and infrastructure policies. The increasing focus on energy efficiency underscores its crucial role in addressing climate change and reducing global energy consumption.

Challenges in meeting energy intensity goals

Despite the substantial investment in energy efficiency, progress toward meeting global energy intensity targets remains slow. In 2021, primary energy intensity decreased by only 0.8 percent year-over-year, falling short of the annual 3.8 percent improvement needed to achieve the Sustainable Development Goal target of doubling the global rate of energy intensity improvement between 2010 and 2030, compared to the average in the period between 1990 and 2010. This gap highlights the need for accelerated efforts and increased investment in energy-efficient technologies and practices across all sectors.

Regional variations in energy efficiency investments

Investment patterns in clean energy vary significantly across regions, reflecting different priorities and economic conditions. In 2024, the Asia Pacific region was estimated to invest nearly 218 billion U.S. dollars in energy efficiency and end-use energy, of which over 85 percent in China. In contrast, the United States' investment in energy efficiency and end-use of energy was below 90 billion U.S. dollars.
