this is alot more than I thought.....considering, each human could only use about 1 part in 7000 million of the total available energy deposited on earth each second.
The total bitcoin network using as much energy as 70 humans is a lot more than you thought?
If that's too much energy, than you need to grab the next 71 humans you see and tell them all to take it easy - they're consuming more energy than the entire bitcoin network!!!
Another estimate of bitcoin network portion of global electricity consumption goes like this:
5TW * 8760 * .47 = 20 trillion kWh annually, where 5TW is an estimate for total global electric generation installed, and 0.47 is a usage factor used by utilities applied to typical residential usage.
The bitcoin mining network uses 70PH/s at 1W/GH/s = 70MW, and it uses that electricty 8760 hours annually, which results in 600 million kWh annually.
600 million / 20 trillion is 30 parts in a million, or 1 part in 30,000.
So you'd really have to find 250,000 people (say, atttending an appearance by the Pope) and tell them all, "Hey, slow down! You're using more energy than the entire bitcoin network!!!"
