Mining is an attractive way to acquire crypto continuously without getting into the trading business. And mining looks poised to only increase in the near future. However, the impact of cryptocurrency mining on the environment and the planet is significant.<\/p>\n\n\n\n
Blockchains need mining for transaction verification and to add new blocks. Mining is crucial because it brings new coins into circulation and enables the blockchain\u2019s development. However, cryptocurrency mining requires a significant amount of computational power. That means a significant amount of energy, too.<\/p>\n\n\n\n
As more and more tokens come into circulation in a Proof-of-Work<\/a> blockchain, the mining difficulty increases. The increasing difficulty is meant to help reduce mining. While that does happen, it also leads people to find better ways to mine. As a result, miners use more advanced hardware like Graphics Processing Units (GPUs) and Application-Specific Integrated Circuits (ASICs). This helps boost miners\u2019 chances of success, but they come with a huge electricity requirement. And a much greater cost to the environment.<\/p>\n\n\n\n Bitcoin, the world\u2019s largest crypto, is estimated to consume nearly 120 Twh (trillion watt-hours) of power annually, according to a Cambridge Bitcoin Electricity Consumption Index<\/a>. Several reports have even established that this energy consumption is equal to that of small countries like Norway.<\/p>\n\n\n\n Mining\u2019s energy inefficiency is especially concerning because energy consumption is mainly from non-renewable fossil sources. The use of such electricity contributes to greenhouse gas emissions and a large carbon footprint. In the long term, this leads to climate change. According to the Cambridge study, crypto mining releases nearly 65 megatons of carbon dioxide into the atmosphere annually.<\/p>\n\n\n\n Besides, the production and disposal of the hardware used in mining can also harm the environment. These devices often contribute to non-biodegradable electronic waste in the end.<\/p>\n\n\n\n In summary, the energy consumption of cryptocurrency mining can be significant. Its impact on the environment and carbon footprint are concerning. As the popularity of crypto continues to grow, things will only get worse. Let\u2019s take a minute to asses the environmental damage mining can cause.<\/p>\n\n\n\n Burning fossil fuels to meet the electricity demands of cryptocurrency mining is a key concern. Additionally, mining generates heat, so mining facilities have to use not-so-eco-friendly cooling systems like air conditioners or fans. These cooling systems generate noise pollution, and the former releases greenhouse gases, too. These greenhouse gases can build up and deplete the ozone.<\/p>\n\n\n\n Some cryptocurrency mining operations require significant amounts of water for cooling purposes. This can strain local water resources, especially when water is scarce.<\/p>\n\n\n\n Moreover, the hardware used in cryptocurrency mining becomes obsolete quickly. It, therefore, has to be replaced on a regular basis. That leads to more non-biodegradable electronic waste, further straining the environment.<\/p>\n\n\n\n The impact of cryptocurrency mining on the global temperature change<\/p>\n\n\n\n One study<\/a> suggests that there has been a 2-degree increase in temperature due to Bitcoin. This is unsurprising, with carbon emissions from crypto operations recording a 126-fold increase\u2014from 0.9 tons in 2016 to 113 tons in 2021.<\/p>\n\n\n\n As concerns about cryptocurrency mining’s environmental impact rise, a few exchanges and cryptos are trying to find remedies. For instance, Ethereum 2022 announced several measures to reduce its carbon footprint by 99.99%. And Ethereum isn\u2019t the only one out there.<\/p>\n\n\n\n As mentioned before, many mining operations are switching to renewable energy sources. Some even set up bases in remote areas, where renewable energy sources are the only option. They are able to go to off-grid areas in this way, thanks to gridless computing<\/a>, which relies on alternative computing resources, such as edge devices.<\/p>\n\n\n\nHow much energy is consumed by cryptocurrency mining?<\/h3>\n\n\n\n
