Colombian President Gustavo Petro issued a stark warning this week: powering cryptocurrency mining with fossil fuels will lead to 'climate collapse.' In a statement that puts the country's mining sector on notice, Petro insisted the future of bitcoin mining must be ecological and run on renewables. He specifically highlighted Paraguay and Venezuela — both nations with abundant green energy — as places already drawing mining investment.
Petro's warning: 'Climate collapse'
Petro didn't mince words. Tapping fossil fuels to run mining rigs, he said, directly undermines global climate goals. The warning lands as Colombia's own energy mix still leans heavily on hydro — but also on oil and coal. For miners operating in the country, the message is clear: don't count on cheap fossil power lasting.
Why renewables matter for mining
Bitcoin mining is energy-intensive by design. When that energy comes from coal or gas, the carbon footprint is brutal. Petro's point is straightforward — shift to solar, wind, or hydro, or risk being shut down. The economics already favor renewables in many places: once the turbines or panels are built, the marginal cost of electricity is near zero. Miners chasing low-cost power have been flocking to regions with stranded or surplus green energy.
Neighbors already cashing in
Paraguay and Venezuela are the obvious examples. Paraguay runs almost entirely on hydro from the Itaipu dam, and its electricity is among the cheapest in the world. Venezuela's grid is a mess, but its state-subsidized power — also mostly hydro — has attracted significant mining, despite other risks. Petro pointed to them as proof that green mining isn't a fantasy. It's already happening, just not enough of it in Colombia.
The timing matters. Global pressure on crypto's energy use hasn't let up. Regulators in the U.S. and Europe are eyeing tougher disclosure rules. Petro's statement aligns with a broader push, but it's also a domestic signal: Colombia won't be a haven for dirty mining.
