The cryptocurrency industry is increasingly criticized for its impact on the environment, with many fearing it consumes too much energy.
Several studies and reports have revealed that the annual energy consumption of the crypto industry exceeds that of many countries combined. Cryptocurrency mining accounts for the largest share of the sector’s total energy consumption. This has had an impact on growing fears about the huge environmental footprint of cryptocurrencies. Some companies, including Tesla, have even announced that they will stop accepting cryptocurrencies in order to control the environmental impact of the sector.
Several bitcoin mining companies have already turned to renewable energy to power their operations and reduce the sector’s heavy reliance on expensive and harmful energy sources. While it is important to highlight the high energy consumption of Bitcoin mining, it is equally essential to know the reasons behind it. This would allow miners to determine the most appropriate solutions to implement without hampering Bitcoin operations.
Understanding Bitcoin Mining
You must first understand how Bitcoin mining takes place to know why it is so energy-intensive. Bitcoin mining involves minting new tokens to put them into circulation. Miners serve as auditors, verifying and validating the authenticity of every bitcoin transaction on the blockchain. Miners are rewarded with Bitcoins after completing verifications worth 1MB.
However, cryptocurrency mining involves solving complex mathematical puzzles to generate a hash, and only the first miner to complete it receives the rewards. The hash is a 64-digit hexadecimal number, usually less than or equal to the target hash. This ensures that each new block validates the next, thus creating the blockchain.
Besides minting new Bitcoins for circulation, miners play a vital role in maintaining the security and transparency of Bitcoin’s decentralized network. They check and confirm Bitcoin transactions almost every ten minutes, preventing users from double-spending and manipulating transactions. Double spending involves using the same tokens for two separate transactions.
Bitcoin mining and energy consumption
In the early days of Bitcoin, people mainly used regular computers for mining activities. The rise in value of Bitcoin has attracted several miners from different parts of the world. However, Bitcoin only has an ideal reserve of 21 million tokens, of which around 83% has already been mined. This means that the number of Bitcoins available for mining also decreases over time.
Thus, the mathematical puzzles that miners must solve to generate new coins and confirm Bitcoin transactions have also become more complex. Solving these mathematical problems requires powerful computer hardware, with great processing power and speeds to generate thousands, millions and billions of hashes per second. These devices need a lot of electricity to operate, which impacts the large amounts of energy used in Bitcoin mining.
The adoption of Bitcoin has grown exponentially over the years with the majority of individuals using it as payment for goods and services. Moreover, it is one of the most lucrative assets today, attracting huge trading volumes on major cryptocurrency exchanges like https://bitiq.live/. The increased use of Bitcoin means that the number of transactions that miners need to verify has also increased on the network.
Due to the robustness of transactions on the Bitcoin network, it is imperative that miners remain engaged 24/7. The constant use of energy-intensive Bitcoin mining hardware undoubtedly increases overall consumption. of electricity. Also, solving math puzzles is a trial-and-error process that requires computers to be constantly running to have the best chance of finding the key, verifying the last transaction block, and receiving the rewards.
Today, experts estimate that Bitcoin mining consumes around 116 terawatt hours or 116 trillion watts per year. This represents about 0.5% of the world’s total electricity supply, which is more energy consumption than most countries. Moreover, a recent study revealed that only around 39% of cryptocurrency mining operations use renewable energy.
Bitcoin mining is undoubtedly a very energy-intensive activity. This is primarily a result of the constant use of powerful computer hardware to verify Bitcoin transactions and mint new Bitcoins for circulation. Nevertheless, cryptocurrency miners have started turning to alternative power sources and more energy-efficient mining hardware.
