The Environmental Impact of Crypto Mining
Crypto mining uses a lot of electricity, which can harm the environment. This activity also leads to higher carbon emissions and electronic waste.
Carbon emissions and greenhouse gases
Bitcoin mining creates a lot of greenhouse gases. In 2020 and 2021, it produced over 85.89 million tons (Mt) of CO2 emissions. This amount equals burning 84 billion pounds of coal or running 190 natural gas-fired power plants.
These emissions contribute to global warming. If Bitcoin mining keeps growing, it could make it hard to meet climate goals like the Paris Agreement’s target to keep warming below 2 degrees Celsius.
It’s crucial to think about how your mining actions impact the planet’s future.
Electricity consumption and energy sources
Crypto mining uses a lot of electricity. The global Bitcoin network consumed 173.42 Terawatt hours from 2020 to 2021. To put this in perspective, if Bitcoin were a country, its energy use would rank 27th worldwide, even surpassing Pakistan.
Most miners rely on coal and natural gas for their energy needs—45% and 21%, respectively. Hydropower makes up 16%, while nuclear energy contributes about 9%. Solar and wind energy make smaller shares at around 2% and 5%.
In the U.S., Bitcoin mining used approximately 36 billion kilowatt-hours (kWh) of electricity by July 2022. This huge consumption contributes significantly to carbon emissions and climate change concerns.
Water usage and its environmental footprint
Bitcoin mining uses a lot of water. It takes enough to fill over 660,000 Olympic-sized swimming pools. This is because cooling data centers needs plenty of water.
Miners use water from rivers and lakes. This affects the local ecosystems. The global water footprint of Bitcoin mining in 2020-2021 was about 1.65 cubic kilometers (km3). That’s huge! Next, we’ll explore the electronic waste generated by crypto mining operations.
Electronic waste generated
Mining for cryptocurrencies does more than consume electricity. It also creates a lot of electronic waste. Special hardware known as ASICs powers many mining operations. These machines have short lifespans, often just 1-2 years before needing replacement.
This constant need for new hardware leads to mountains of e-waste, similar in scale to what countries like the Netherlands produce. Broken or outdated ASICs end up in landfills if not properly recycled.
This adds another layer of environmental impact you should consider if you’re into crypto mining.
