Global Renewable Energy Growth: Progress and Challenges

Record Growth Yet Insufficient Progress
In 2024, the global renewable energy sector achieved a record addition of 582 gigawatts (GW), marking a 15.1% increase from the previous year. Despite this growth, the International Renewable Energy Agency (IRENA) reported that these figures fall short of the targets set during the COP28 climate summit in Dubai, where over 100 countries agreed to triple renewable energy capacity to 11.2 terawatts (TW) by 2030. To meet this ambitious goal, an annual growth rate of 16.6% is required from 2025 to 2030, necessitating the installation of approximately 1.122 TW each year. As of the end of 2024, the total installed capacity stood at 4,443 GW, significantly below the tripling target.
Key Drivers of Renewable Energy Growth
The surge in renewable energy generation is primarily driven by solar and wind technologies. Reports indicate that solar energy production increased by approximately 31% in the first half of 2025, contributing to a significant portion of the global electricity supply. Notably, renewable sources surpassed coal for the first time, generating around 5,100 terawatt-hours (TWh) compared to coal's 4,896 TWh. This shift is largely attributed to substantial investments in solar infrastructure, particularly in China and India, which are leading the global renewable energy expansion.
Challenges in the United States
In contrast to the global trend, the United States has faced setbacks in renewable energy development. The Trump administration's recent overhaul of tax credits for solar and wind projects has raised concerns about future investments. Reports indicate that U.S. coal-fired power generation rose by 17% in the first half of 2025, highlighting a troubling trend as the country grapples with rising electricity demand. The International Energy Agency (IEA) has lowered its growth expectations for U.S. renewable capacity by 50% compared to previous projections, reflecting the impact of federal policies on the clean energy transition.
Criticism and Opposition
Critics argue that the current pace of renewable energy deployment is insufficient to combat climate change effectively. United Nations Secretary-General Antonio Guterres emphasized the urgency of accelerating the energy transition, warning that the window to limit global warming to 1.5 degrees Celsius is rapidly closing. Additionally, the IEA's projections indicate that while global renewable energy capacity is expected to double by 2030, the U.S. is likely to lag behind due to policy constraints.
Official Statements and Responses
Francesco La Camera, IRENA's Director-General, expressed optimism about achieving the 2030 targets, stating, “We may be close to still more than 700 gigawatts, possibly 750 gigawatts (of capacity additions) in 2025, and this means we are closing the gap.” However, he acknowledged the need for stronger policies and investment momentum to facilitate this growth.
What's Next?
As the world prepares for the upcoming COP30 climate conference in Brazil, discussions will focus on strategies to enhance renewable energy deployment and address the challenges posed by fossil fuel reliance. The outcomes of these negotiations will be critical in shaping the future of global energy transition efforts.

- “Renewables are deployed faster and cheaper than fossil fuels — driving growth, jobs, and affordable power.” — Antonio Guterres, United Nations Secretary-General
- “The renewables market has made this choice, it is the cheapest way to produce electricity.” — Francesco La Camera, IRENA Director-General
- “I don’t see any reason to believe that renewables won’t double by 2030.” — Robert Brecha, Senior Climate and Energy Adviser at Climate Analytics
The global renewable energy landscape is evolving rapidly, yet significant challenges remain, particularly in the United States. The upcoming climate talks will be pivotal in determining the trajectory of renewable energy policies and investments worldwide.
