On one hand, it was already in the first half of 2025 that a record in renewable energy investment was registered, and companies were already investing more than 386 billion in new investments, by far the same percentage ratio as in 2024. It indicates that despite the discomfort with regional policy, the transition to clean energy is accelerating, as offshore wind not only remains a growth factor currently but also gains momentum with the powerful installations erected worldwide by China (such as the largest solar park on the planet).
Investment boom stimulates the proliferation of renewable energy
Windtech International says that the first half of 2025 recorded 10 million dollars more investment worldwide in new renewable energy projects than it had at the same period last year. The first half of 2025 saw total investment in new renewable energy projects worth $386 billion, the swiftest rate of adoption of clean energy at a global level ever witnessed.
A primary contributor was offshore wind, with up to 39 billion dollars invested, already exceeding the combined investments made in the sector in 2024, to a total of 31 billion dollars. The large project pipelines and government timetable of auctioning offshore wind contribute to the variation in activity, mostly.
There are radical changes in regional investment patterns.
Offshore wind continued to grow, but application of external debt by utility-scale solar and onshore wind decreased by 13% versus 2024 and was the lowest share of invested capital in the world since 2006. The steepest drop occurred in the USA as regional patterns saw renewable investment by the new rule go down by 36% after late 2024 due to policy uncertainty as a result of the election.
By contrast, the EU-27 experienced an increase of at least $30 billion, or 63 per cent, in investment by developers shifting attention to European offshore wind resources, particularly in the North Sea. The largest market would still be mainland China, as it will contribute 44% to global new investment in the first half of 2025.
China is in the lead with huge solar installations
According to Carbon Credits, solar, wind, and power grid updates saw the global investment in renewable energy strike new records in 2024/25. Simultaneously, China led the pack by constructing a sun farm that is Chicago-large, proving how the globe can be remaking its energy infrastructure.
Investment in renewable power and fuels around the globe hit a record of 622.5 billion in 2024. This occurred despite high levels of interest rates and supply shocks. Utility-scale solar contributed 63 per cent of the total, and wind contributed 35 per cent, with much of the growth due to cost reductions and policy assistance.
This project harnesses the vast sunshine in the desert and is part of the national effort of China to aggressively increase renewables. China will add 212 GW of solar and 51 GW of wind capacity in the first half of 2025. Meanwhile, the decrease in carbon emissions totaled approximately 1% which demonstrates that increasing growth and reducing emissions are not mutually exclusive.
Future speculation on investment issues and opportunities
Despite this growth, the developing regions are not investing in renewable energy. As an example, sub-Saharan Africa has 20 percent of the world’s population and gets less than 2 percent of the clean energy investment. P.S. To resolve climate and energy equity, government financial resources and global collaboration will have to increase the intensity of investment in underserved areas.
The H1 2025 renewable energy investment of up to $386 billion worldwide is an open door to clean energy transition, with offshore wind development propelling growth and the enormous solar plants being deployed in China defining new deployment goals. Regardless of the uncertainty surrounding regional policy in US markets, the general trend toward renewable energy is positive and boosted by the reduction of costs and growing awareness of the need to tackle climate concerns.
