## Network Power Consumption (P_{N})

A baseline value for network power consumption can be found by multiplying the total network hashrate with a “best case” value for the power/hashrate ratio that a miner can achieve.

P

_{N}= H_{N}x P_{M}/ H_{M}P

_{N}= 296000 (GH/s) x 110.6 (W) x 1000 (MH/GH) / ( 31.2 (MH/s) x 10^6 (W/MW) )P

_{N}= 1049 MW

As a side note, people often confuse power (W) and energy (power x time, eg. Wh). For instance, assuming an average daily P_{Nd} of 1049 MW we can calculate that days Energy consumption by multiplying by the number of hours in a day.

E

_{Nd}= P_{Nd}x T_{d}E

_{Nd}= 1049 (MW) x 24 (h/d) / 1000 (GW/MW)E

_{Nd}= 19.7 GWh
