"Those critics of Bitcoin who point to its energy usage (as of this writing, ~75 terawatt hours per year) seem unwilling to acknowledge the energy usage that keeps the US dollar afloat. The US economy used almost 29,000 terawatt hours in 2019. As confirmed by the US Treasury Department, the value of the dollar is backed by all the goods and services in the US economy which would also include its energy sector. Furthermore, in 2019 world energy consumption was something on the order of 120,000 terawatt hours. Bitcoin uses ~0.25% of US energy consumption and less than 0.05% of world energy consumption."
