The International Energy Agency (IEA) predicts that global investment in energy efficiency will reach $660 billion in 2024, with significant increases expected in emerging markets. However, to meet net-zero targets by 2030, investment needs to rise to $1.9 trillion. Skilled labor shortages in the energy sector pose a major challenge, with the IEA calling for more inclusive policies to encourage greater participation of women. The report also highlights the urgent need for energy-efficient cooling solutions and emphasizes the critical role of energy efficiency in reducing reliance on fossil fuels.
