Wind grew far slower than solar in 2024
The United States Energy Information Administration, the federal agency that tracks how much new power capacity the country builds each year, counted 5.1 gigawatts of new wind added in 2024, against 30 gigawatts of new solar. A gigawatt is enough new capacity to power hundreds of thousands of homes. The same year, the agency counted 10.3 gigawatts of new battery storage, equipment that stores power to release later. Solar added almost 6 times as much new capacity as wind.
Figures are new capacity added in 2024, not the total amount of each kind of power already running in the country.

Onshore wind had its slowest year since 2014
Onshore wind, meaning turbines built on land rather than out at sea, added just 6.474 gigawatts across the whole country in 2023, according to the Land Based Wind Market Report from the United States Department of Energy. A summary of the same research, published by OurEnergyPolicy, calls 2023 the slowest year for new wind construction since 2014. It names 3 reasons. Interest rates were high, raising the cost of borrowing money to build a wind farm. Connecting a new wind farm to the power grid, called interconnection, faces long delays. And siting, meaning finding and winning approval to build on land, has grown harder as local opposition rises. The country now has about 150.5 gigawatts of onshore wind built up over decades, and developers spent 10.8 billion dollars on new onshore wind projects in 2023 alone.
Rising costs and disappearing credits
A 2026 report from Energy Connects names more reasons the gap keeps widening. A federal moratorium, meaning a temporary block on new approvals, and slower project approvals under the current administration. Inflation and strain on the supply chain. Tariffs, taxes on imported equipment, that raise the cost of building a wind farm. And a wind tax credit that lowers building costs and is due to end in 2026.

Solar costs have continued to come down more than previously expected, and wind costs have been rising the past couple of years.

But we are not placing a lot of investment in the development of new wind at this moment, because the risk profile is too great.

The 2026 plan widens the gap further
For 2026, the same federal agency forecasts solar adding 43.4 gigawatts of new capacity, more than 3 times the 11.8 gigawatts forecast for wind. It forecasts battery storage adding 24 gigawatts, more than double what wind is forecast to add. The agency describes the 2026 wind total as more than double what wind actually added in 2025, without giving an exact 2025 number.
These are the federal agency planning figures for 2026, not an audited result. The agency states the 2026 wind figure as more than double what wind actually added in 2025, without giving an exact 2025 total.

The largest onshore wind project due to open in 2026 is SunZia Wind in New Mexico, at 3,650 megawatts, meaning 3.65 gigawatts. Energy Connects reports that SunZia will supply enough power for more than a million homes in the Southwest.
