The Bitcoin network’s energy consumption is equivalent to that of an entire country, according to data released today by the crypto portal Digiconomist. The network generates 114 million tonnes of CO2 annually, roughly matching the carbon footprint of the Czech Republic.
Beyond carbon emissions, the environmental impact extends to water usage. Digiconomist’s analysis reveals the Bitcoin network consumes 3222 Gigaliters of drinking water each year – a figure comparable to the entire annual water consumption of Switzerland.
The intensive resource demands stem from Bitcoin’s underlying “Proof of Operate” technology. This system requires participants, known as miners, to solve complex cryptographic puzzles to validate transactions and generate modern Bitcoins. The competitive nature of this “mining” process necessitates significant computational power and substantial electricity consumption. Often, this electricity is sourced from fossil fuels, contributing to the high CO2 output.
Digiconomist’s data further illustrates the individual impact of Bitcoin transactions. A single transaction now generates as much CO2 as watching approximately 117,000 hours of YouTube videos, or processing 1.5 million Visa transactions.
The findings come amid growing scrutiny of the environmental sustainability of cryptocurrencies. In 2025, the Czech government faced a scandal involving a Bitcoin donation worth one billion crowns (approximately $45 million USD) to the Ministry of Justice, as reported by the Slovak daily Denník N.
AI systems are also contributing to environmental concerns, with a projected carbon footprint equivalent to that of New York City by 2025, and a water footprint comparable to global annual bottled water consumption, according to Digiconomist.
