You need to allow lower cost per kWhr in your survey. The lowest value of 20 cents is still WAY too high even for residential power cost.
Actually yeah. You probably need to scrap this and set a proper baseline first before conducting the survey, Your cost for electricity I think isn't the only outdated piece of data.
Suggest spend a bit of time in the Mining section to wrap your head around current trends. Plus a few studies to also refer to for benchmarking from 2017 and this year. Fact, there's also where you'll find more respondents... Not here in Services.
