- Bitcoin’s annual electricity consumption adds up to 45.8 TWh (45.800.000.000 kWh)
- The corresponding annual carbon emissions range from 22.0 to 22.9 MtCO2
- This level sits between the levels produced by the nations of Jordan and Sri Lanka
a lot of bitcoin infrastructure was build up/is running in China, probably because of cheap energy costs (compared globally)
China only: “According to our Simulation, the annual energy consumption of the Bitcoin Blockchain in China will reach its maximum of 296.59 terawatt hours (TWh) in 2024.
This exceeds the electricity consumption of Italy and the Netherlands in 2016.” by the way, Germany consumed 585 terawatt hours (TWh) in 2018.
As a result, there will be CO2 emissions of 90130.5 metric tons, which is more than the emissions of the Czech Republic and Portugal in 2016, but much less than Germany in 2018.
This corresponds to 10.77 kilograms per 1 dollar of added value.
One small consolation of these robust figures might be that Bitcoin uses a much “greener” energy than most developed countries.
# how many kWh are 1 TWh? (src) echo '10^12' | bc 1000000000000 Wh # 1000 Wh = 1kWh echo '1000000000000/1000' | bc 1 TWh = 1.000.000.000 kWh # in words: # 1 TWh are 1 US-billion kWh or 1 DE-Milliarde kWh
