The green transition brings risks for crypto-assets’ valuation. Political and social choices on energy sources and energy consumption levels are needed for the green transition to net zero. These choices could lead policymakers to privilege certain productive activities and their use of energy to meet climate strategy targets and avoid crowding out the limited renewable energy sources for crypto mining. It is unlikely that bitcoin investors have currently priced in the negative ecological externalities and authorities’ possible policy measures. To make bitcoin more Competing miners race to use computers to solve complex mathematical puzzles using extremely powerful hardware - receiving new Bitcoin as a reward for their efforts.

Bitcoin is powered by blockchain, which is the technology that powers many cryptocurrencies. A blockchain is a decentralized ledger of all the transactions across a network. Groups of approved transactions together form a block and are joined to create a chain. Think of it as a long public record that functions almost like a long running receipt. Bitcoin mining is the process of adding a block to the chain. Library resources Each individual computation made by an ASIC is referred to as a hash, and the number of hashes an ASIC produces per second is referred to as the hashrate. A single hash can be thought of as a lottery ticket to solving a block and earning a bitcoin reward. A miner’s share of the network’s aggregate hashrate—the amount of computing power generated by all ASICs on the network—represents the bitcoin rewards the miner can expect to earn over a given time period.

In addition to competition, bitcoin halvings could also accelerate green energy adoption among miners. Halvings happen every 210,000 blocks, approximately every four years.5 As the name suggests, halvings reduce bitcoin block rewards by 50%, which lowers revenues earned by bitcoin miners by almost the same amount if there is no change in the price of bitcoin. Expected in 2024, the next halving will reduce block rewards from 6.25 BTC to 3.125 BTC issued per block.6 With competition and halvings pressuring miners to seek out efficiency gains wherever possible, bitcoin miners are discovering that environmentally sustainable practices may be the next frontier to explore. Does Crypto Mining Damage Your GPU/Computer? Bitcoin is not the only cryptocurrency on the block though. Understudied cryptocurrencies added 50% on top of Bitcoin's energy needs last year, according to de Vries. Some use a similar mining technique to Bitcoin. Others use alternatives in which the block creation process depends on wealth rather than computational power. "Theoretically this modification could also be implemented in Bitcoin and would remove any incentive to use specialized mining hardware, saving both energy and electronic waste," he concluded.

Bitcoin is not innocuous. Transactions are processed by “miners” using massive amounts of computing power in return for rewards in the form of Bitcoin. By some estimates, the Bitcoin network consumes as much energy as entire countries like Argentina and Norway, not to mention the mountains of electronic waste from specialized machines used for such mining operations that burn out rapidly.
