IEA Report: Bitcoin mining accounts for 0.03%-0.06% of global carbon dioxide emissions each year

According to a report released by the International Energy Agency (IEA) on July 23, Bitcoin mining may generate 10-20 megatons of carbon dioxide emissions per year, accounting for 0.03%-0.06% of global energy-related CO2 emissions. Bitcoin's recent price and hash rate growth has accelerated its energy consumption, which is estimated to have consumed 29 TWh in the first half of 2019. Exceeds Ireland's annual energy consumption (26 TWh). The report further pointed out that Bitcoin mining sites usually choose to have cheap renewable energy, and about 76% of the energy consumed by Bitcoin is renewable.
