## Network Power Consumption (P<sub>N</sub>)
2018-02-08 15:19:32 +00:00
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.

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