Software and hardware engineering will no doubt need to reorient their design practices more around power efficiency.

    For comparison:

    On the face of it, the question about energy use is a fair one. According to the Cambridge Center for Alternative Finance (CCAF), Bitcoin currently consumes around 110 Terawatt Hours per year — 0.55% of global electricity production,

    The most reputable such estimate comes from the University of Cambridge Bitcoin Electricity Consumption Index, according to which the global bitcoin network currently consumes about 80 terawatt-hours of electricity annually, roughly equal to the annual output of 23 coal-fired power plants, or close to what is consumed by the nation of Finland.

  2. Tomi Engdahl says:

    Computers, data centers and networks consume 10% of the world’s electricity. 30% of this electricity goes to power terminal equipment (computers, mobiles and other devices), 30% goes to data centers and 40% goes to the network.
