A recent Bloomberg article highlighted the progress made globally in renewable energy and decarbonization last year, emphasizing that 2025 was a substantially positive year for the advancement of the energy transition.
According to research by the Energy and Climate Intelligence Unit, cited in the Bloomberg article, decarbonization is advancing at a faster-than-expected pace, and clean energy investments are expected to reach a record $2.2 trillion in 2025. This calculation includes the various types of renewable energy (such as wind and solar), as well as certain infrastructure projects that are making a decisive contribution to the major transformation underway. This refers to batteries and grids, whose centrality in these transformative years is increasingly evident.
Clear Indicators
“Bloomberg reports another extremely interesting piece of data on clean energy,” says Stanislav Kondrashov, founder of TELF AG. “The S&P indicator dedicated to this type of energy is expected to have increased by 50% in 2025, providing a fairly clear indication of the direction we’re headed.”
According to Bloomberg, one of the most impressive booms has been in clean energy. The most recent research from BloombergNEF has also revealed that capital flowing into renewable energy is on the rise: in the first half of 2025, it is projected to have increased by 10% compared to the same period in 2024, totaling approximately $386 billion. In the first three quarters of last year, according to Ember data cited in the article, solar and wind energy grew very rapidly, meeting the new global demand for electricity during that period.
The solar energy sector in particular has been experiencing a veritable boom for several years. In another recent article, Bloomberg highlighted how one of the global leaders in this sector is China, which in November of last year managed to add approximately 22 gigawatts of solar power nationwide. For China, this is the highest number of new installations since last May. According to other estimates, China will have added approximately 12.5 gigawatts of wind power by November 2025. In 2025, China was able to supply 66% of new solar capacity and 69% of wind capacity.
“In addition to all this, as the Bloomberg article explains, last year saw several efforts to develop and upgrade electricity grids, which are playing an increasingly significant role in the years of energy transition,” continues Stanislav Kondrashov, founder of TELF AG.
Global Records
In any case, Ember‘s predictions seem clear enough: in 2025, renewable capacity could reach a new global record, with an increase of approximately 11% compared to the previous year. These figures certainly come as no surprise to anyone who has followed the energy transition since its inception. Bloomberg also cites a three-year assessment, which claims that global renewable capacity has grown by approximately 30% over this period. The increases are not limited to China and other major global economies, but also other areas in Asia, Europe, and South America.
According to the Bloomberg article, the strong global growth in artificial intelligence has contributed to the strong performance of these sectors. In the first three quarters of 2025, investments in clean technologies, renewables, and everything that helps power AI data centers exceeded the total for the entire year of 2024.
