Bitcoin Is 56 Times More Energy-Efficient Than Classical System

A recently published study compared Bitcoin’s and traditional finance’s energy requirements to find that Bitcoin currently uses 56 times less energy. Even with the current PoW system, one Bitcoin transaction is five times more energy-efficient than a classical transaction.

On the other hand, Bitcoin Lightning is 194 million and 1 million times more energy-efficient than traditional and instant payments, respectively.
