Global Renewable Energy Developments (May–June 2025)

Global renewable energy generation saw significant growth and pivotal changes during May and June 2025. A surge in clean energy investments is driving record-high spending: the International Energy Agency projected global energy investment to reach $3.3 trillion in 2025, with $2.2 trillion flowing into clean energy technologies reuters.com reuters.com. According to an IEA report released on June 5, 2025, solar power is expected to attract the largest share – around $450 billion in 2025 – making it the single biggest area of energy investment reuters.com reuters.com. IEA Executive Director Fatih Birol noted that despite economic uncertainties, most ongoing renewable projects have not been derailed: investors may be in “wait-and-see” mode for new projects, but “in most areas we have yet to see significant implications for existing projects” reuters.com reuters.com. This optimistic outlook comes amid record renewable energy expansion on the ground. In China, for example, installations of solar and wind power surged to unprecedented levels this period – The Guardian reported on June 26, 2025 that China added 198 GW of solar and 46 GW of wind capacity between January and May 2025, an astonishing build-out “enough to generate as much electricity as Indonesia or Turkey” theguardian.com theguardian.com. China’s solar capacity alone has now surpassed 1,000 GW – roughly half of all solar capacity worldwide theguardian.com theguardian.com. At the same time, global renewable generation hit new milestones: in the United States, clean power provided a majority of electricity for three consecutive months in spring 2025 – March through May – the first time ever for such a sustained period reuters.com reuters.com. U.S. data showed record outputs from solar farms and wind and hydro, enabling clean sources to outproduce fossil fuels despite slight dips in wind output reuters.com reuters.com. Across the Atlantic, European officials pushed ahead with long-term climate targets: the EU is preparing to propose a 2040 emissions goal – and Denmark’s Climate Minister Lars Aagaard urged that “short-term challenges” like budget pressures must not “halt the transition in Europe,” underscoring that expanding renewables and self-sufficient clean power is essential for both climate and energy security reuters.com reuters.com. Overall, the late-spring 2025 period was marked by rapid renewable energy growth – especially in solar and wind – alongside policy debates and new technological strides, as detailed in the sections below.
