The energy landscape in the United States is evolving at an unprecedented pace, with renewable energy now surpassing traditional fossil fuels such as coal and gas. By the end of 2024, large-scale wind and solar production has exploded, increasing by nearly 299 million megawatt-hours (MWh) since 2019. This remarkable increase not only meets the growing energy demand but also marks a significant shift away from fossil fuels. The energy transition is well underway, with renewable energies gradually taking the lead.
Renewables Outpace Fossil Fuels in Production
In 2019, renewable energy production surpassed coal only for 38 days. Fast forward to 2024, and that number has exploded to 294 days. The trend suggests that coal, once a dominant energy source, will never again outpace renewables, especially with the expansion of solar and wind energy and the continued closure of coal-fired power plants. By 2026, renewable production is expected to surpass that of coal and gas by a significant margin, marking a historic shift in the American energy sector.
The rise of renewables has also reduced the market share of fossil fuels. Ten years ago, coal and gas represented about two-thirds of the energy mix. During the 2020 pandemic, the share of fossil fuels fell below 60%, and by the end of 2024, it had dropped further to 57.8%. As renewable energy continues to capture a larger market share, the energy transition is clearly gaining momentum.
Solar and Wind Lead the Charge
Looking ahead, the Energy Information Administration (EIA) forecasts a continued decline in fossil fuel production by 2026, even as overall demand increases. By then, coal and gas production will have decreased by 103 million MWh, while solar and wind production will have increased by 465 million MWh. Solar energy alone is expected to grow by 56.9%, exceeding 340 million MWh by 2026—nearly 8% of total U.S. energy demand, a huge leap from less than 1% in 2017.
This rise in renewable energy is not just a national trend but a reflection of a broader shift towards greener energy sources. States like Texas are leading the way, with renewables already making up a significant portion of their electricity supply.
Texas: Leading the Renewable Charge
As the largest energy user in the United States, Texas drives much of the change in the energy sector. In 2024, wind and solar made up 34.6% of Texas’s electricity, nearly tripling from 11.7% in 2015. Solar energy, which accounted for only 1% of Texas’s energy production in 2019, has seen explosive growth. By 2024, solar production had exceeded 48 million MWh, capturing 10.4% of the market—an incredible tenfold increase since 2019.
By 2026, wind and solar are expected to surpass gas as the primary source of production in Texas. The EIA estimates that wind and solar will produce 200.9 million MWh (40.1% of demand) compared to 194.6 million MWh for gas (38.9%). This historic shift is particularly remarkable in a state traditionally dominated by fossil fuels.
Energy Storage: Key to a Greener Grid
One of the biggest innovations facilitating this transition is energy storage. In 2019, energy storage was virtually nonexistent, but by the end of 2024, the United States is expected to have over 30,000 MW of installed battery storage capacity, with an additional 15,000 MW expected to be added by the end of 2025. These batteries store excess energy generated by solar or wind during the day and release it when demand is highest, such as in the evening or morning.
California is a concrete example of how energy storage is already making a significant impact. By the end of 2024, the state had installed 13,391 MW of battery storage capacity, including 11,462 MW of utility-scale storage. This capacity has allowed California to avoid reliance on gas-fired power plants during peak demand periods, such as during heat waves when solar energy is less available. On October 7, 2024, California ISO (CAISO) set a record for battery discharge of 8,354 MW, helping to avoid resorting to more costly and polluting gas-fired generation.
Energy storage now plays a vital role in day-to-day operations, reducing the need for gas-fired generation and supporting a more sustainable energy grid. It helps lower emissions, decrease fuel costs, and improve the overall efficiency of the grid.
The Future of a Cleaner Energy Grid
The transition to a cleaner energy grid in the United States is unstoppable, even if its pace may still be subject to debate. With large-scale solar, wind, and energy storage projects underway, renewables are expected to continue their rapid growth. As fossil fuel production declines and renewables capture an increasingly larger share of the energy market, the future looks increasingly green for the American energy sector.
In the coming years, this transition will redefine how energy is produced and consumed in the United States and beyond, bringing not only environmental but also economic benefits. With solar energy and wind energy at the forefront, the United States is proving that a sustainable and profitable energy future is within reach.
