Currently you need ~160MHashes/s to generate 1 BTC on average per day. Power draw is somewhere between 1-1.5 W/MHash/s, so ~4-6 kW/day can be expected (a minig rig that small would have a bit more of overhead from other components, so I'll use the 6 kW/day further on)
hmm so basically for every BTC 144 pounds of carbon dioxide are created (1kwH creates about a pound on average)?! why is it necessary to waste so much energy and create such a huge carbon footprint?
I think Sukrim meant 6 kWH/day, so it's not 6 * 24 = 144, it's 6 * 1.
