RIYADH: The International Energy Agency has projected global investment in energy efficiency to reach a record $660 billion in 2024, maintaining the levels seen in 2022. Significant increases are expected in emerging markets, with Africa anticipated to see a 60 percent rise, the Middle East a 40 percent increase, and Latin America a 20 percent boost. Despite this positive growth, the Energy Efficiency 2024 report emphasizes that to meet net-zero targets by 2030, global investment in energy efficiency needs to rise to $1.9 trillion.
