A new study published in the journal Cell Reports Sustainability has unveiled the staggering environmental impact of Bitcoin, revealing that each transaction consumes a massive 16,000 liters of water – equivalent to filling an entire swimming pool. This alarming revelation further highlights the cryptocurrency’s unsustainable practices and the urgent need for eco-friendlier alternatives.
The study’s author, Alex de Vries from the Vrihe Universiteit Amsterdam, attributes Bitcoin’s excessive water consumption to the energy-intensive mining process that underpins the cryptocurrency. This process, known as proof of work, involves powerful computers solving complex mathematical problems to validate transactions and secure the network.
The sheer volume of energy required for Bitcoin mining has a significant impact on the global electricity demand, and with it, the associated water usage. In 2021 alone, Bitcoin mining consumed an estimated 1,600 gigaliters of water, a figure that is projected to rise to 2,200 gigaliters in 2023.
Moreover, the study found that Bitcoin’s water footprint is rapidly escalating, increasing by 166% between 2020 and 2021. This surge is primarily driven by the cryptocurrency’s rising price, which incentivizes more miners to join the network, further intensifying the energy and water consumption.
The environmental consequences of Bitcoin’s water usage are far-reaching, particularly in regions facing water scarcity. The diversion of water resources towards Bitcoin mining could exacerbate existing water shortages and strain local communities’ access to clean water.
