Sorry, no complete source, I’ve calculated it myself. The discrepancy arises from several issues: 1. The article you quote is from last year. Current estimates for BTC are around 200 TWh/a, not 140 as in the article. 2. The article looks at BTC only. My statement was BTC + ETH. 3. Energy vs electricity 4. There is also the issue of energy production vs consumption (differences arise from energy used for the production of energy, as well as transport losses). 5. It is plausible that electricity is “just” 10% to 35% of energy usage, would need to look that up. With all that, I stand by my statement that crypto uses 1% or more of the world electricity consumption.
