Discussing Environmental Impact of Bitcoin Cryptocurrency


Cryptocurrencies are far from their rather dark beginnings. While digital money was originally denounced as instruments for thieves and speculators by the conventional financial world, the sector made considerable headway in establishing itself as a legitimate (perhaps) changing area.

Discussing Environmental Impact of Bitcoin Cryptocurrency

Bitcoin (BTC) has seen the tremendous price and user growth, but concerns regarding the implications of widespread cryptocurrency acceptance are still there. In particular, several sceptics and ecologists have expressed concerns about bitcoin mining energy usage, which may increase carbon emissions and climate change.

Why Mining Requires Energy?

The competitiveness of the proof-of-work blockchains is the reason for these exorbitant energy prices. Rather than maintaining account balances in a central database, transactions in cryptocurrency are recorded by a dispersed miners’ network, stimulated by block rewards. The proponents of cryptocurrency claim that this system has several benefits over centralized currencies since it does not depend on a trusted intermediary or a single failure point. However, numerous energy-intensive calculations are required in the puzzles for mining.

One of the environmentalists’ main concerns is that mining is less efficient as cryptocurrency prices rise. Mathematical jigsaw puzzles get harder to generate blocks in bitcoin as price increases, while transaction output stays constant. This implies that the network’s processing capacity and energy consumption will increase in order to handle the same amount of transactions as before.

Defending Mining

Some cryptocurrency supporters have minimized the energy usage of cryptocurrencies, saying that mining companies tend to cluster around regions with a plentiful supply of renewable energy. According to these assertions, because bitcoin miners are not geographically restricted, they can roam about in search of more energy sources.
The calculations of bitcoin’s renewable energy use are contentious and often contested. It is estimated that even the most optimistic projections of renewable energy usage will result in a net contribution to carbon emissions from the network.

Fossil Fuels and Cryptocurrency

All of this has coalesced to establish a connection between cryptocurrency and fossil fuels in a manner that many investors have not yet recognized. Coal and other fossil fuels are a significant source of energy throughout the globe, providing power for bitcoin mining activities and various other sectors. However, coal combustion is a major contribution to climate change due to the carbon dioxide emitted during burning coal.

Other Consequences

In addition to energy consumption, cryptocurrency mining results in a considerable quantity of electronic waste due to the rapid depreciation of hardware over time. This is particularly true for Application-Specific Integrated Circuits (ASICs), which are specialized hardware designed specifically for mining the most popular digital currencies. Because these circuits cannot be utilized for any other purpose, they rapidly become outdated compared to other computer hardware.

Regardless of whether you favor or oppose bitcoin and other proof-of-work blockchains, they use huge amounts of energy. The vast bulk of this energy consumption is generated by coal and other fossil fuel burning. Nonetheless, proponents of bitcoin assert that renewable energy sources provide a significant part of this total. While the precise numbers are still up in the air, even the most optimistic forecasts suggest that mining contributes significantly to carbon dioxide emissions.

Cryptocurrencies without Mining

Also worth mentioning is that a significant number of cryptocurrencies have little environmental effects, which is something to be celebrated. Proof-of-stake blockchains, in particular, do not need mining, enabling transactions to be processed with the same amount of energy as a traditional computer network, saving the environment. Ethereum is anticipated to transition to a proof-of-stake blockchain shortly, but the plan has been met with opposition from miners.


Because of the calculations required for mining, Bitcoin and other proof-of-work cryptocurrencies use a significant amount of energy. According to the most recent estimations, the bitcoin network consumes as much energy in a year as the whole nation of Argentina combined. Some proponents claim that renewable energy sources provide as much as 74 per cent of Bitcoin’s energy requirements, but these claims are subject to debate. In addition, the bitcoin network produces 11.5 kilotons of electronic trash each year. However, not every cryptocurrency has a major negative effect on the environment. Many of them do not engage in any mining at all.
