Clean energy investments – additional information

The amount of funding provided for clean energy worldwide has steadily increased over the last decade. In 2004, clean energy investments totaled just over 45 billion U.S. dollars and increased to 279.8 billion U.S. dollars in 2017. 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.

The United States alone accounts for a significant share of global clean energy investments. In 2018, funding for clean energy initiatives totaled 64 billion U.S. dollars in the country. About 3.4 billion U.S. dollars of these investment funds were from venture capital and private equity funding. In 2010, China invested almost 32 billion U.S. dollars into clean energy stimulus funds. China remained the highest-ranked country regarding clean energy investment in recent years. Global investment in clean energy was mostly driven by asset financing for wind and small distributed capacity, most notably rooftop solar energy. Utility-scale solar and wind investments have accounted for the vast majority of renewable energy investments.
