LOL wut?

Bitcoin is a 400 Megawatt waste of energy.

Do you even know what a Megawatt is?

He does not, probably, but I do: It is a measure of effect. You can convert it to horsepowers if you like. It is work (or energy) per time unit.

Then can you tell me how many Megawatts Bitcoin actually uses?

Here we go:

A typical mining rig 100W at 60 GH/s
Network hashing rate is currently estimated to 20000 GH/s, so mining is now

100*20000/60 = 33 kW

Say we have 10000 clients running on normal PC's, each drawing 50W, but is used for other purposes, say we allocate 10W to each, that is 10*10000= 100kW.

Mining and clients 133kW. That is 178 horsepowers.

Running the network one year is 60*60*24*365 * 133000 J = 4194 GJ
Same as 1.165 MWh or 3975 million BTU.

At 9.7 kWh/liter, that is 120000 liters of diesel.

I need to double check these calcualations before I post...

Or 4194000000 N*m

But a lot of people are still running gpus. About 1 MH/s per Watt.

This is where I took the info.
