Overview
- Solar generation overtook coal in monthly U.S. output in May 2026 when Ember found solar supplied 12.8 percent of electricity and coal supplied 12.2 percent.
- Solar plus battery storage led new builds in early 2026 and made up roughly 91 percent of new generating capacity in Q1, according to SEIA and Wood Mackenzie.
- The White House announced nearly $700 million to support coal plants and exports while also taking steps that curtailed some federal clean-energy incentives and projects.
- Grid limits and permitting hurdles are the main near-term constraints on faster solar growth, with long interconnection queues and local siting reviews slowing project deliveries.
- Utilities are contracting large amounts of solar and batteries but still plan some new natural-gas capacity to meet fast-rising demand from data centers and electrification, and analysts say solar could pass coal on an annual basis within a few years if integration and permitting improve.
