According to the United States Energy Information Administration (EIA), wind and solar energy generated more electricity than coal for the first time in history during the first seven months of the year. This astounding feat, as reported in the EIA’s Monthly Energy Review for July 2024, highlights a substantial shift in the country’s energy environment, with renewables increasingly taking center stage.
From January to July 2024, renewable energy outshined coal in terms of electricity output, setting an unprecedented trend. This is a watershed moment in the United States’ ongoing transition to cleaner energy sources, as coal, a long-time cornerstone of the country’s power grid, continues to dwindle.
Rising influence of wind and solar
Wind energy, in particular, has grown dramatically, exceeding coal in electricity output for two months in a row this year. In March, wind energy installations generated 45.9 gigawatt-hours (GWh) of power, beating coal’s 38.4 GWh. In April, wind energy reached a record high of 47.7 GWh, while coal produced 37.2 GWh.
Ric O’Connell, GridLab’s executive director, stressed the significance of this move, saying, “I think it is an important milestone. I think you’re seeing a solar surge and a coal decline and hence the lines are crossing.”
This spike in renewable energy is not an isolated event. The United States is on course to add an impressive 36.4 gigawatts of solar utility-scale electric generating capacity in 2024, nearly double the 18.4 gigawatts added the year before. Wind energy production is also on the rise, up about eight percent from 2023. By June 2024, a further 2.5 gigawatts of wind power had been constructed, with another 4.5 gigawatts expected by the end of the year.
These initiatives demonstrate the tremendous acceleration of renewable energy infrastructure in the United States. Over the last 25 years, wind energy capacity has increased from 2.4 gigawatts in 2000 to more than 150 gigawatts by spring 2024. Similarly, solar energy capacity has increased by more than 99 gigawatts over the same period. Meanwhile, coal capacity has steadily fallen, reaching 177.1 gigawatts by April 2024, down from 315.1 gigawatts in 2000.
Grid resilience under extreme conditions
The growing dominance of renewables has also played an important role in improving grid resilience, particularly during severe weather occurrences. As summer temperatures rose in 2024, perhaps making it the hottest year on record, renewable energy sources such as wind and solar helped fulfill rising energy demand without causing substantial disruptions.
O’Connell credited wind, solar, and battery storage with stabilizing Texas’ electricity infrastructure during this summer’s heat waves. In California, authorities with the California Independent System Operator (CAISO) praised renewable energy and battery storage for avoiding major power outages, despite the state experiencing the warmest month on record in July.
This shift to renewables not only marks a watershed moment in US energy production but also represents a broader trend toward a more robust and sustainable energy future. As the country grapples with the effects of climate change, its reliance on wind, solar, and other renewable sources is expected to become an increasingly important part of its energy strategy.
