Energy consumption of Ethereum (ETH) and VISA transaction as of May 1, 2023

One single blockchain transaction of Ethereum equaled the energy consumption of less than several thousands of VISA card transactions. This according to a source that tries to estimate the energy consumption of Ethereum (ETH). It does so by estimating how much income miners possibly spend on electricity, as there is no institution that tracks how much energy the cryptocurrency actually consumes. This same methodology was also applied to the energy consumption of Bitcoin. Ethereum energy consumption is of importance for developments regarding NFTs and other applications of decentralized finance or DeFi - as the market share of the Ethereum blockchain in DeFi far exceeds that of other blockchains.

以太坊（ETH）的单笔区块链交易所消耗的能量，相当于数千张维萨（VISA）信用卡交易的总和。这一数据源自试图估算以太坊能耗的资料来源。该来源通过估算矿工可能花费在电力上的收入来进行估算，因为没有任何机构追踪加密货币实际消耗的能源量。同样的方法也被应用于比特币的能源消耗估算。以太坊的能源消耗对于非同质化代币（NFT）及其他去中心化金融（DeFi）应用的发展至关重要——鉴于以太坊区块链在DeFi市场中所占份额远超其他区块链。
