How many of these server have no real purpose? So many of them host pointless websites, generate loads of useless data, or transfer tons of spam from one server to another. One badly written function, used on millions of computers that increase cpu usage by 1% more than it should will waste MWatts of power, yet nobody is worrying about that.. Thousands of new smartphone models released every year, and I don't hear people screaming about environmental damage. Want less environmental damage? Spend more time on efficient code, write everything in machine code, and don't comment on HN. After all to post one comment, how many server, switches, routers, computers need to be on? What a waste!
