Many social and environmental groups have criticised cryptocurrencies for having a huge carbon footprint and harming the environment. So, why and how is crypto mining bad for the environment? Let's see
Why Is Crypto Mining Bad For The Environment?
The energy-intensive processes required for each transaction and for "mining" new coins are what have the biggest negative effects on the environment from cryptocurrencies. The amount of energy needed varies between cryptocurrencies; some, like the most widely used cryptocurrency, Bitcoin, use relatively little energy, while others, as we will see below, demand a lot.
It is estimated that each Bitcoin transaction uses around 2100 kilowatt hours (kWh), which is roughly what an average US household consumes in 75 days. Using non-renewable energy sources to power cryptocurrencies like Bitcoin can result in exorbitant greenhouse gas emissions. The annual emissions of 97.2 megatonnes of carbon dioxide, or almost the same amount as Argentina as a whole, are comparable to the carbon footprint of bitcoin.

Higher processing power enhances the probability of correctly predicting the PoW solution, which has encouraged miners to form mining pools or establish mining farm facilities. In a mining pool, a number of miners, each with their own power-hungry equipment, attempt to solve the puzzle at the same time and divide the rewards according to the amount of "effort" or processing power that each miner provided.
On the other side, a mining farm is a data center that houses hundreds or even thousands of ASIC servers that are constantly mining for Bitcoins. These mining farms still require large quantities of electricity to run them, even if the concentration of these computers in one location supports a decrease in energy usage and the specialized ASIC hardware was created to use energy more efficiently.
In total, Bitcoin mining consumes 91 TWh of electricity annually, which is more than Finland's annual electricity consumption and seven times more than Google's. This amount represents approximately 0.5 percent of global electricity consumption.
I hope now you know why and how is crypto mining bad for the environment.
