In Januarythe mining power demand was in the range from 25 to 90 MW. After the Byzantium update in Octoberthe demand dropped shortly to a range from cointube payment proof. The mining power demand visit web page the Ethereum blockchain would have been at approximately 0.

This estimate and the one in section 3. The two dashed forum bitcoin 2019 show the development forum bitcoin 2019 the power demand when the block difficulty grows according forum bitcoin 2019 the difficulty bomb and the hardware efficiency either increases linearly dashed brown line or exponentially dashed green line.

The average power demand of the scenarios 1 and 4 would exceed 10, GW before the beginning of These scenarios seem, from the energy system's perspective highly unlikely, forum bitcoin 2019 the worldwide installed generation capacity for electricity of 6, GW in Central Intelligence Agency, The green, and turquoise solid lines show the mining power demand if the block difficulty rises linearly.

The average power demand in of the scenarios 2 and 5 would be at 1. The dotted lines represent the scenarios 3 and 6 in which the difficulty forum bitcoin 2019 at forum bitcoin 2019 level of the October 31, and the hardware efficiency increases exponentially or linearly.
