The energy landscape in the United States is undergoing a transformative shift as solar power outpaces coal for the first time in history. In May 2026, solar energy accounted for 12.8% of the nation’s electricity output, surpassing coal’s 12.2% share. This development marks a turning point in the country’s move towards renewable energy, despite federal initiatives supporting coal production.
Solar Energy Achieves Unprecedented Growth
In May 2026, solar power generated a record 45.5 terawatt-hours (TWh) of electricity, marking a significant milestone in the U.S. energy sector. This achievement highlights a 17% increase from solar output recorded in the same month the previous year. The momentum suggests that solar energy will continue to set new records, especially as solar generation peaks during summer months.
According to Ember, a global energy think tank, solar energy’s rise has been steady as coal’s share has diminished. Improved technology, cost reductions, and heightened investor interest have driven solar’s expansion across different sectors.
Declining Coal Power and Rising Renewables
The decline of coal power has been evident, with coal generation plummeting to an all-time low of 39.3 TWh in April 2026, before a slight rebound to 43.4 TWh in May. However, this still represents an 11% decrease compared to May 2025. Over the past five years, coal’s share of the U.S. electricity mix dropped from 19.7% to 12.2%, while solar’s contribution more than doubled from 5.4% to 12.8%.
The shift towards renewable energy is a global trend. The International Energy Agency (IEA) forecasts that by 2030, renewables will constitute nearly 45% of global electricity generation, positioning them as the predominant energy source.
Renewables Meet Rising Electricity Demand
As U.S. electricity demand grows, driven by factors such as the expansion of AI infrastructure, domestic manufacturing, and the electrification of transport and heating, renewable technologies are increasingly being used to meet new consumption needs.
Despite federal efforts to bolster coal production, investments continue to flow into solar energy. President Donald Trump’s administration recently announced plans to invest nearly $700 million in supporting coal-fired power plants, yet industry experts note that investment trends are guided more by economic returns than policy.
Investment Trends and the Global Energy Transition
Martin Pochtaruk, CEO of solar panel maker Heliene, emphasized that capital is often directed towards technologies with the most promising financial returns. China’s dominance in solar panel production, accounting for about 80% of global output, has been instrumental in reducing costs and boosting solar deployment worldwide.
The U.S. milestone is part of a broader global shift towards renewables. Last year, renewable energy generation surpassed coal globally, with solar and wind power becoming preferred sources due to their economic advantages and environmental benefits.
FAQ’s
Q1: Why did US solar power surpass coal generation in May 2026?
US solar power surpassed coal generation due to continued growth in solar installations, improving technology, lower costs, and increased renewable energy capacity. Solar supplied 12.8% of US electricity in May 2026, compared to coal’s 12.2%.
Q2: What does this milestone mean for the US energy sector?
The milestone highlights the ongoing transition toward cleaner energy sources. It shows that solar energy is becoming a major contributor to the US electricity mix and is increasingly replacing traditional coal-fired power generation.
Q3: Why is coal generation declining in the United States?
Coal generation has declined because of aging power plants, competition from lower-cost renewable energy and natural gas, environmental regulations, and growing investments in cleaner energy technologies.
Q4: Will solar power continue to outperform coal in the future?
Energy analysts expect solar power to continue expanding its share of electricity generation as new solar projects come online and demand for clean energy grows. Many experts believe solar could surpass coal on an annual basis within the next few years.
