Soaring solar and a surge in hydro push more coal off the US grid

Recent data reveals a significant shift in the US energy grid, as renewable energy sources, particularly solar and hydroelectric power, continue to outpace coal production. Following a brief spike in demand attributed to data center growth last year, which saw a 3 percent increase and a temporary rise in coal usage, the market has stabilized and returned to a slow growth pattern. In the first quarter of 2026, overall demand in the US increased by just 1.5 percent compared to the same period last year. This modest rise can be attributed to atypical weather conditions, with the western regions experiencing unseasonably warm temperatures while the east was hit by a deep freeze. Therefore, a broader analysis over the year will be necessary to fully understand the implications of this slight uptick in demand. The standout trend remains the remarkable growth of solar energy, which surged by 24 percent compared to the previous year, effectively offsetting 80 percent of the increased demand. Meanwhile, the combined output from major renewable sources—wind, solar, and hydro—rose by an impressive 11 percent, significantly outpacing the growth in demand at 1.8 times. As a result, fossil fuel consumption experienced a downturn, with an overall decline of around 3 percent year-over-year. Notably, coal usage plummeted by more than 10 percent, while natural gas saw a slight increase during the same timeframe. However, the future of natural gas prices remains uncertain due to ongoing geopolitical tensions in the Persian Gulf, which could impact energy trends moving forward.
