Solar energy installations in 2025 are expected to reach record highs, continuing a notable upward trend over the past three years. Maintaining this rapid growth while boosting wind energy capacity remains a critical challenge.
At the United Nations COP28 climate conference in December 2023, world leaders made a historic commitment to triple global renewable energy capacity by 2030.
According to the International Energy Agency (IEA) and the International Renewable Energy Agency (IRENA), increasing renewable capacity to at least 11 terawatts (TW) by 2030 is essential to keep global temperature rise within 1.5°C.
Reaching the 1.5°C target and ensuring reliable power systems requires more than just rapid expansion. Success depends on balancing:
"We now know we can build renewables at speed. The next step is to prove we can keep up this momentum on solar every year and accelerate the pace on wind and hydro too."
Speed and consistency will be crucial to maintaining affordable clean electricity while achieving these climate goals.
Author's summary: Rapid solar growth in 2025 highlights the potential to triple renewables by 2030, but sustained, balanced efforts in wind and grid infrastructure are essential for reaching climate targets.
