According to EIA data reviewed by the SUN DAY Campaign, solar, wind, and batteries are set to supply virtually all net new US generating capacity in 2026. This growth is expected to continue from their strong performance in 2025, with solar being the fastest-growing source of US electricity. 0%.
9% a year ago. 2% compared to the same period in 2024. 1% a year earlier.
7% during the first 11 months of 2025. 5 MW. 6 MW) being added in the next 12 months.
2 MW over the next 12 months. The trends seen in 2025 YTD are expected to continue and accelerate over the coming 12-month period. 2% of net new capacity – and even higher if small-scale solar were included.
In 2026, this growth is expected to lead to a significant shift in the US generating capacity mix, with renewables and battery storage playing a major role.
As we move towards a cleaner energy future, it's clear that renewable sources like solar and wind are becoming increasingly important. The EIA's projections for 2026 are a testament to this trend, and it will be interesting to see how the US energy landscape continues to evolve in the coming years.
