## Energy

The average industrial cost per kilowatt hour of electricity.

Energy Cost: $0.07 kW/h ## The Math ##### Variables ### Let the following be assigned: ĥ = global hash rate (TH/s) ĥm = individual miner's hash rate (TH/s) em = individual miner's energy consumption (kWh) c = energy cost (kWh USD) β = blocks per hour r = block reward (btc) m = total number of simulated miners cmb = energy cost per miner per block (USD) v = bitcoin intrinsic value (USD) ##### Equations First, find the total number of simulated miners m in the best case scenario (all using best combination of hash rate and energy consumption). Second, find the energy cost per miner per block cmb in kilowatts-per-hour by dividing the energy consumption of an individual miner in kWh by the number of blocks found in an hour, and then multiplying the result by the constant cost of each kilowatt hour. $$m = {ĥ \over ĥ_m}, c_{mb} = c{e_m \over β}$$ Finally, the lower bound on the intrinsic value of a coin's generation is the total system energy cost per block divided by the number of coins generated per block. $$v = {m \times c_{mb} \over r}$$ ##### Results With 4,728,750 miners and an individual energy cost of$0.019 kW/h the system energy cost per block is $89,858. Since the current block reward is 12.5 BTC then the energy cost per coin is$7,188.65.

##### Think of it Like

The energy cost to create a Bitcoin is akin to the cost of digging up and processing ore as if it were it a piece of metal.
