The world lacks 30 trillion euros to finance development and energy transition Santander estimates that between 2026 and 2030, global investment needs will be around 50 trillion euros and the financing gap will reach 30 trillion euros. Climate projects – including grid development, renewable energy, energy storage and electrification – account for €22-26 trillion of this deficit. The bank believes that it will not be possible to close the gap without the cooperation of the state and private capital. Separately, Santander draws attention to savings in Europe: households in the region have about €32 trillion in net financial assets, but a significant portion of these funds are invested outside Europe.
