As transport and heat sectors increasingly electrify, demand will increase, providing a stronger investment case for new clean capacity. Tracking progress on how our electricity is generated is critical, as it is not only a huge source of greenhouse gases, it is also needed as an enabler of a cleaner and more efficient energy system overall. Other clean non-fossil fuel technologies are also playing their part – nuclear could be entering a renaissance in some countries but there have also been set backs, as unusual weather affected both hydro and nuclear plant. Often at a lower cost than fossil fuels and faster than other sources of clean electricity. The world has abundant supplies of wind and solar, and this report documents how, through technical innovation and policy execution, this abundance has been converted into on-the-ground energy supply. Wind and solar are growing at between 15-20% pa based on a 10 year average, so look set to exceed increases in annual electricity demand by the end of 2023. This report showcases the significant strides made in the transition towards a sustainable and decarbonized energy system, and the promising outlook for achieving the critical milestone of peak emissions from the power sector – perhaps in this coming year. We are pleased to introduce the Global Electricity Review 2023 from Ember, now in its fourth year, in which we highlight again the continued surge in clean power generation worldwide. However, just how quickly power sector emissions will fall is not yet set. Urgent work is needed on ensuring wind and solar can be integrated into the grid: planning permissions, grid connections, grid flexibility and market design.įalling fossil generation means not only that the coal power phasedown will happen, but also that–for the first time–a gas power phasedown is now within reach. More growth is needed from all other clean electricity sources, while more attention to efficiency is needed to avoid runaway growth in electricity demand. Wind and solar will need to maintain high growth rates this decade, even as they mature. These will drive reductions in emissions for other sectors, and will put more pressure to build clean power more quickly.Ī new era of falling power sector emissions is very close, thanks to the electricity superpowers of wind and solar. It also accelerated electrification: more heat pumps, more electric vehicles, more electrolysers. Russia’s invasion of Ukraine made many governments rethink their plans amid spiking fossil fuel prices and security concerns about relying on fossil fuel imports. 2022 will be remembered as a turning point in the world’s transition to clean power.
