At this price and that diff. it isn't even capable of covering the energy bill.
I got 5 GH/s at 1.000 Watt.
What do you mine with? 200W per Gh sounds like too much. What card and hashrate? Maybe you can play around with intensity and settings and get only slightly lower hash rate at significantly lower power consumption.
But at that price of electricity there is probably no way you make a real profit. And I thought my 0.15/KW euro was expensive
