Re: how much does it cost to "produce" 1 BTC currently? and how much power is used?

You need ~160W (calculating with 1W per MHash/s) to mine a bitcoin in a day currently. If you let a GPU that consumes 160W/h and calculates 160 MHashes/s run for a day, in theory you have generated a BTC.

160W/h *24h = 3870W/day --> 3,87 kW/day

ok, thanks!

Also CO2 is generally (mis?)used as an "equivalent" factor for greenhouse gases. Read a bit on http://en.wikipedia.org/wiki/Global-warming_potential and http://en.wikipedia.org/wiki/Co2e before you start acting as if every greenhouse gas emission is CO2...

agreed, i didn't mean to imply that co2 is equivalent to all greenhouse gases. i simplified and mentioned only co2 because i didn't wanna complicate the discussion on that side.
