Why did US greenhouse gas emissions increase in 2025 according to Rhodium Group?

The Rhodium Group cited a cool winter, increased demand from data centers and crypto mining, and higher natural gas prices as primary drivers for the 2025 emissions rise.

What role did data centers play in the 2025 US emissions increase?

The significant growth in data centers and cryptocurrency mining led to a jump in electricity demand, increasing the need for power generation, including from fossil fuels.

Did renewable energy grow in the US during 2025?

Yes, solar power generation increased by 34% in 2025, and zero-carbon emitting energy sources collectively supplied 42% of American power.

US Emissions Surge: Fossil Fuels Reignite Pollution

The United States experienced a 2.4% increase in heat-trapping gas emissions from fossil fuels in 2025, marking a reversal from previous environmental gains. This rise is attributed to a combination of factors including a cold winter leading to increased heating demands, and the explosive growth of data centers and cryptocurrency mining, which amplified electricity consumption.

This surge in pollution occurred alongside a notable 13% rise in coal power generation, partly driven by increased natural gas prices. Despite these setbacks, renewable energy sources showed considerable progress, with solar power generation jumping 34% and non-carbon emitting sources now providing 42% of American electricity, demonstrating a continued economic viability for cleaner energy options.
