Even at $0.2 kW/h the most expensive electrcity in the world I can still gain a tiny profit mining ETH.
Keep in mind the OP mentioned that their rig had a HD 6950 (ancient Terrascale card) and a R9 270 (low end for mining at all but at least it's GCN).
I doubt they were mining ETH on those cards, don't think the R9 270 had a 4GB option and the ETH miners don't tend to work on pre-GCN cards at all.
20 cents/KWH isn't the most expensive electric in the USA, much less the world - but it's certainly a lot higher than the US average.
I still dont catch what the point to have tiny profit and be proud of that. Thats a bit weird.
