The 2024 IEA World Energy Investment report examines the global energy financing landscape over the past decade, highlighting the stable capital structure where debt finances 46% and equity 54% of energy investments worldwide. Debt plays a more significant role in the power sector and Asia, while equity dominates in the fuel supply sectors of the Middle East and Eurasia. Fossil fuel companies have reduced debt levels post-pandemic, funding investments through retained earnings. Clean power projects heavily leverage debt due to high upfront costs, contrasting with clean fuels and emerging technologies like battery storage and hydrogen, which rely more on venture capital. Governments globally, through national oil companies and state-owned enterprises, maintain a stable 37% share in energy investments, with public finance playing a critical role in mobilizing commercial finance for clean energy projects. The shift towards renewable energy suggests increasing reliance on debt financing, especially for projects like solar and wind power, but challenges remain in high capital costs and sector-specific risks, particularly in emerging economies. Addressing these challenges will require robust policies and support from development finance institutions to lower financing costs and attract private investment, essential for achieving sustainable global energy goals.
