Climate Action Network International warns that the COP31 "35-by-35" electrification target will fail unless powered by sustainable renewable energy, not nuclear or fossil fuels. The IEA's Electrification report envisions a scenario where nuclear power could make a comeback, but CAN International emphasizes the importance of sustainable energy sources. The report also presents a scenario where gas-fired generation could increase, but CAN International stresses the need for renewable energy expansion. They call for a focus on rapid, just, and equitable deployment of sustainable renewable energy solutions to meet rising electricity demand. The section emphasizes the importance of advancing electrification and decarbonization together to address climate change and reduce inequalities, highlighting the need to avoid new fossil fuel lock-in and direct public finance towards renewable energy systems. The key message is that electrification must be backed by grid-scale renewable energy to achieve economy-wide decarbonization and reduce fossil fuel use, with a focus on providing developing countries with the necessary support to shape their own renewable energy futures and ensuring public finance supports the transition to renewable energy.
