If 1 ZH/s = 1,000,000,000 TH/s
and the global mean miner efficiency is 30 W/TH
1,000,000,000 TH/s Γ 30 W/TH = 30 GW
30 GW Γ 8,760 h/year β 263 TWh/year
The global mean miner electricity cost at $0.05/kWh:
263 TWh = 263 Γ 10βΉ kWh
Cost/year = 263e9 kWh Γ $0.05 = $13.15B
BTC produced per year:
β 450 BTC/day Γ 365 β 164,250 BTC/year
So the average miner on the network electricity cost per BTC:
$13.15B / 164,250 BTC
$80,000 per BTC.
Which just so happens to be right on the bounce.
