Ember's 2023 Global Electricity Review: Record drop in emissions driven by renewables surge

The 2023 Global Electricity Review published by Ember (global energy think tank) brings encouraging news regarding the reduction of CO2 emissions related to electricity. This new study examines data from countries representing 93% of the global demand for electricity.

The reduction in CO2 emissions related to electricity is partly due to the decrease in the share of coal in electricity production and the rise of renewable energies, particularly in China. This marks the first annual drop in the use of coal, oil, and gas for electricity production outside of a recession or a global pandemic, despite the increase in global demand.

Low-carbon energy sources (renewables and nuclear) generated nearly 39% of the world’s electricity in 2022, a record level highlighted by the Ember think tank, with impressive growth in solar and wind energy. Investments in renewable energies continue to rise, with $303 billion invested in solar energy and $243 billion in wind energy in 2021.

To achieve the Paris Agreement’s goals, the report emphasises the importance of cooperation between governments, businesses, and investors in supporting research and development in renewable energy, promoting energy efficiency, and enabling developing countries to access clean technologies.

Wind and solar reached a record 12% of global electricity in 2022, and power sector emissions may have peaked.

In his publication, “Low-cost solutions to global warming, air pollution, and energy insecurity for 145 countries,” Mark Jacobson (a researcher at Stanford University) demonstrates that 145 countries could cover all their energy needs through a 100% WWS (Wind Water Sun) combination. The investments required for this transition would be repaid in just six years. Such a transition would ultimately cost less than maintaining the current energy system. This theory supports Ember’s report, which calls for global cooperation among major players to combat climate change.
