A bottom-up approach to determine crypto-mining electricity usage. Another approach to estimating cryptocurrency mining's effects on electricity use in the United States is to build up an estimate from what we know about individual facilities. To that end, we have worked to identify as many U.S. cryptocurrency mining facilities as possible.
