Bitcoin Mining Generates 30,000 Tons of E-waste

 Waste from Bitcoin mining will reach 30,700 tons in 2021, five times more than Luxembourg's

According to Forbes, Bitcoin mining consumes around 127 terawatt-hours of electricity per year – equivalent to the entire annual electricity consumption of Norway. For every Bitcoin that miners get, the system will consume about 707 kilowatt hours, 11 times more than Ethereum.

Cryptocurrency mining process emits a lot of CO2 because of the increasing difficulty of solving the algorithm, forcing the machines to work more. The use of fossil energy such as oil and coal to operate excavators also causes many negative impacts on the environment.

However, not only the problem of electricity consumption, the mining process also requires equipment power, making it generate a lot of waste. Currently, Bitcoin miners use their own integrated circuits (ASICs) instead of taking advantage of the power of computers or graphics cards as before. However, ASICs have a short lifespan, around 18 months. Once obsolete, they will become waste.

According to experts, the switch from PoW to PoS mechanism will significantly save energy consumption. Mining companies are also promoting the use of green energy such as wind power, solar power and hydroelectricity instead of fossil fuels. Increasing the life of the excavator is also a way to help reduce waste into the environment.

Some cryptocurrencies, like Ethereum, have changed the algorithm on the new mining process to make the miner use less energy. However, experts say that while Bitcoin is still the most valuable digital currency, mining models that pollute the environment still exist.
