Most people don’t have to deal with electricity figures in their daily life. As a result, they may find it difficult to put Bitcoin’s energy footprint into proper perspective. The goal of this page is to make Bitcoin’s electricity consumption more tangible and meaningful for a diverse audience by comparing it to other uses of electricity.
However, visitors should note that all comparisons face three major limits:
Note: All comparisons below are based on our best-guess estimate. The listed comparisons are for illustrative purposes only and do not constitute an endorsement nor any other form of value judgment. We aim to continually update this page with relevant and applicable comparisons. This is an ongoing iterative process. We are always open to feedback, comments, and suggestions for new comparisons or reliable data sources – please contact us here.
Total World Production & Consumption
First, we consider Bitcoin’s share of the world’s total yearly electricity production and consumption. A reference to global energy production and consumption has been added as well to account for the wide array of industries that primarily rely on sources other than electricity (e.g. diesel fuel). In a similar fashion, some Bitcoin mining facilities are known to directly tap into energy assets at the production point rather than procuring electricity via the regular grid.
Industrial & Residential
Next, we set up Bitcoin mining against other industrial and residential uses of electricity (or energy, depending on the nature of the activity).
Bitcoin’s closest and most referenced real-world analogue is gold. While they arguably share utilitarian similarities as stores of value, gold and Bitcoin also demonstrate common consumptive traits, (e.g. the proportional relationship between unit price and increased production resulting in increased resource consumption).

Note: energy intensity estimates of gold mining on a global scale are difficult to verify and can vary considerably. This figure is based on an older estimate from 2006 which may not be representative of the state of the gold mining industry today. It nevertheless provides a useful input for modelling a simple baseline scenario that assumes little infrastructural upgrades in gold mines over the last decade.
We would like to end this brief excursion on a more amusing note, with a wink to our parent institution and a dearly held British tradition.
