US solar power surpasses coal in April

The US renewable energy sector achieved a significant milestone in April, as solar electricity production surpassed coal-fired generation for the first time. This development comes after a period of rapid growth in solar capacity, driven by its position as the cheapest way to add generating capacity in most of the US. The situation heading into April was marked by a decline in coal use, despite repeated government attempts to prop it up, and rapid growth in solar energy.

However, this growth started from a small base, and the early months of the year are typically marked by seasonally low solar production. As a result, growth above 20 percent year over year still left solar providing only 6 percent of the power on the US grid, a sharp contrast to coal's 16 percent. The preliminary data suggested that May 2026 saw solar power pass coal-fired generation for the first time in the US.

However, with the official release of April grid data by the Energy Information Administration, it became clear that solar electricity production had passed coal a month earlier. A substantial chunk of solar production never reached the grid, as it's produced by rooftop installations and used in the building they sit atop. The rapid growth of solar energy has been driven by its position as the cheapest way to add generating capacity in most of the US.

This trend is expected to continue, with solar energy becoming an increasingly important contributor to the US grid. Why this matters: The shift towards solar energy has significant implications for the US energy sector, as it continues to transition away from fossil fuels. The growth of solar capacity is likely to accelerate, driven by declining costs and increasing demand for renewable energy.

This trend presents opportunities for developers and businesses to invest in solar energy, while also driving innovation and reducing greenhouse gas emissions. However, challenges remain, including the need for improved grid infrastructure and policies to support the integration of distributed energy sources. As the US continues to transition towards a low-carbon economy, the growth of solar energy will play a critical role in shaping the country's energy future.
