Worldwide investment in renewable energy 2004-2022
The amount of funding provided for clean energy worldwide has steadily increased over the last two decades. In 2004, clean energy investments totaled 32 billion U.S. dollars and increased to a peak of 495 billion U.S. dollars in 2022. The significant increase in investment funding indicates that the industry has matured greatly. Policy support for renewable sources, an accelerating industry, and the emergence of publicly listed companies that own renewable energy assets (also known as yieldcos) have driven the steady rise in clean energy investment.
