That means with bitcoins total hash-rate of 177,943,954 GH/s that its energy consumption would be around 88,971,977 Watts or 88.9 Megawatts of power.
Does this seem responsible? We are basically polluting on a massive scale to make pennies on the dollar.
You have to assume at some point governments will come together to put this to an end?
No, it is not responsible as human beings to waste electricity. Bitcoin is an experiment to revolutionise the global monetary system. It has the potential to save millions of people's life-savings, help overseas workers save fee remitting money home. Innovations do not come without costs. The electricity used are costs of technological advancement.
I would be safe to say that the global gaming industry (PC/console/mobile) uses more energy than Bitcoin does. Are they also irresponsible playing too much games and using more electricity than needed? Will governments come together and put an end to this?

Haha well you are missing a huge part of what gaming is and who that market belongs to
Three biggest names in gaming?
1)Steam
2)Microsoft
3)SOA
All three operate and pay taxes in america. Well this is something that one should get used to. Humans are flawed. They are greedy and are going to abuse just about anything that they can.
It's unfortunate to see this happen but not much can be done to prevent an ASIC company to mine with new hardware before releasing it, right?
I mean I agree. And believing in free market I cant even disagree with what they are doing. I just see it as harmful in the long run. But perhaps i'm just too paranoid.
