Quick takeaways
- China added a significant amount of low carbon electricity in 2023, but its demand for electricity is growing faster, resulting in continued construction of fossil fuel capacity.
- The concept of regression to the mean suggests that luck tends to even out over time, as demonstrated through Cambridge United's football performance where teams often perform better after a coach is sacked.
Deep dives
China's Renewable Energy Expansion
China added 420 terawatt hours of low carbon electricity in 2023, enough to match the electricity generation of the UK or power France. Despite the growth in renewable energy, China's demand for electricity is growing even faster, leading to continued construction of fossil fuel capacity.
