Clean energy is growing rapidly, as annual deployment of a number of key technologies has accelerated in recent years driven by policy support and continued cost declines. From 2019 to 2023, clean energy investment increased nearly 50%, reaching USD 1.8 trillion in 2023 and growing at around 10% per year across this period.
The clean energy economy is a major industrial sector and an important contributor to the global economy. However, its benefits remain too concentrated with most of clean energy deployment occurring in China and advanced economies.
