- Ripple states that XRP is 57,000 times more environmentally friendly than Bitcoin, making it a sustainable cryptocurrency.
- The high energy consumption of Bitcoin is due to the Proof of Work consensus mechanism and the necessity of mining.
Bitcoin has already been criticized in the past by Ripple CEO Brad Garlinghouse for its enormously high energy consumption for mining. Now, in a new blog post, Ripple states that the real problem lies in Bitcoin’s Proof of Work (PoW) consensus mechanism, since enormous amounts of energy are consumed for the processing of transactions.
The PoW algorithm is used by Bitcoin to validate transactions. In order to process the transactions, enormous power capacities for mining are required to mine new Bitcoins. Ripple describes that an application-specific device, an ASIC miner, has an environmental cost of $1,500 per year for mining, and a new, powerful miner can cost as much as $6,000 per year.
A study carried out in 2018 showed that hundreds of thousands of mining devices consume the same amount of electricity as Ireland within one year. Currently, Bitcoin’s estimated energy consumption per year is just under 60,890 TWh and has fallen from 77,207 to the new level since the halving in May this year.
Bitcoin consumes as much electricity as Chile does per year. According to Digiconomist, Bitcoin’s carbon footprint is 36.95 million tons of CO2, comparable to New Zealand. According to the report, after the all-time high in 2018, energy consumption initially dropped significantly, but then rose sharply again (freely translated):
(…) when the Bitcoin bubble burst in 2018, sending prices tumbling from a high of almost $20,000 (£15,600) at the end of 2017 to below $4,000 (£3,135), consumption also crashed and has only recently started soaring again….
