How the global landscape for energy investment is changing
…It found that cumulative investments in efficiency, electrification, biofuels and electricity generation from renewables and nuclear together avoided over $260 billion in fuel import costs among energy importing countries and regions in 2025.
Another major trend has been the falling cost of key energy technologies, led by battery storage systems and solar PV, which have seen costs decline by nearly 80% since 2015 thanks to innovation and growing markets. If the costs of technologies across the energy system had remained where they stood a decade ago, an additional $2.5 trillion in spending would have been required in 2026 to…

Thematic session: Demand-side energy data for improving lives
Event backgroundIn today’s context of energy market volatility and economic uncertainty, energy efficiency remains one of the most effective tools to support affordability, energy security and competitiveness. The 11th Annual Global Conference on Energy Efficiency will bring together global leaders to accelerate policy action at this critical moment. The availability, quality, and use of demand-side energy data are essential enablers of effective energy efficiency policy.As clean energy transitions accelerate, understanding energy consumption across end uses, sectors and population groups is increasingly important, yet, demand-side energy data remains limited, particularly in the emerging economies. This limitation constrains…
