Less Bitcoin mining in Texas because of climate change

June is normally the month when the first heat waves start in Texas, the largest state in the United States. Due to climate change, these heat waves are becoming more frequent (and are relatively longer). And that has consequences for Bitcoin, because Texas is where most Bitcoin mining companies operate. Authorities in Texas are asking large consumers of electricity to use less during the summer months, so that more energy is available for families, who need it for air conditioning.

June thus marks the start of the Electric Reliability Council of Texas’ (ERCOT) Four Coincident Peak (4CP) program, which aims to incentivize large electricity consumers to reduce their consumption during periods of high demand. And that’s exactly what the largest bitcoin mining companies have been doing.

In its latest production release, published on July 3, 2025, Riot Platforms announced that it had produced just 450 Bitcoins in June, compared to 514 Bitcoins in May, or a 12% drop. Riot CEO Jason Les explained that this voluntary strategy to reduce electricity consumption contributes to both grid stability and the competitiveness of his company.

Cipher Mining reported on July 2nd that it had produced 160 Bitcoins in June, compared to 179 Bitcoins in May. Finally, MARA Holdings also reported a 25% drop in production month-over-month, with 211 Bitcoins in June compared to 282 Bitcoins in May. So the number of Bitcoins mined in the next two months is going to be highly dependent on how warm it gets in Texas
