Ethereum vs. Cardano

the ultimate energy consumption breakdown

We want to analyze the yearly energy consumption of Cardano and Ethereum, so that you can make an informed decision which blockchain you want to support and how your activity impacts the environment. First we are going into the yearly energy consumption of Ethereum and what level of activity one transaction is equivalent to.

Ethereum's Consumption



= 7211157.31

average households per year

As Ethereum uses a proof of work algorithm to execute its transacitons, it requires enormous amounts of energy to execute a single transaction, which has accumulated to energy consumption of countries like Bangladesh, a top 40 consumer on a yearly basis.

It doesn't have to be this way

Proof-of-Stake solutions are superior when it comes to energy efficiency and allow you to minimize negative impact your blockchain activity has on our environment
