Bitcoin is 1000x less energy-efficient than credit cards

It’s hard to conceive how inefficient bitcoin is in terms of energy consumption:

An index from cryptocurrency analyst Alex de Vries, aka Digiconomist, estimates that with prices the way they are now, it would be profitable for Bitcoin miners to burn through over 24 terawatt-hours of electricity annually as they compete to solve increasingly difficult cryptographic puzzles to “mine” more Bitcoins. That’s about as much as Nigeria, a country of 186 million people, uses in a year.

And to put in terms more relatable to Americans:

Since the average American household consumes 901 KWh per month, each Bitcoin transfer represents enough energy to run a comfortable house, and everything in it, for nearly a week. On a larger scale, De Vries’ index shows that bitcoin miners worldwide could be using enough electricity to at any given time to power about 2.26 million American homes.

Included is a quote from De Vries:

“Blockchain is inefficient tech by design, as we create trust by building a system based on distrust. If you only trust yourself and a set of rules (the software), then you have to validate everything that happens against these rules yourself. That is the life of a blockchain node,” he said via direct message.

And lastly, award the eco-friendly category to credit cards:

But since Bitcoin is thousands of times less efficient per transaction than a credit card network, it will need to get thousands of times better.
