The Cambridge Bitcoin Electricity Consumption Index (CBECI) provides a real-time estimate of the total electricity load and consumption of the Bitcoin network. The model is based on a bottom-up approach initially developed by Marc Bevand in 2017 that takes different types of available mining hardware as the starting point. Given that the exact electricity consumption cannot be determined, the CBECI provides a range of possibilities consisting of a lower bound (floor) and an upper bound (ceiling) estimate. Within the boundaries of this range, a best-guess estimate is calculated to provide a more realistic figure that we believe comes closest to Bitcoin’s real annual electricity consumption.   Data cited at: Cambridge Centre for Alternative Finance
