Cryptocurrency mining requires huge energy costs. Any real estate agent knows that the price of a property is largely determined by its location. In the crypto space, energy consumption has become such a key criterion, given that the world is facing the problem of climate change, not to mention fluctuations in electricity prices themselves.
Energy consumption of bitcoin reaches 707 kW, while for ether this figure is 62.56 kW. Advanced processors power complex algorithms on the bitcoin blockchain. Ethereum 2.0 requires much less electricity, making Ether a greener cryptocurrency.
In addition, Ethereum is based on a proof of stake (PoS) model that allocates mining power based on the size of the miner's stake. Bitcoin is based on a proof of work (PoW) model and requires huge amounts of electricity to maintain processing power.
