"As for units I see nothing wrong with KWPH." - well it doesn't surprise me that you don't and that's because you (by your own admission) lack a formal education. The units of energy when expressed in kilowatt hours in standard form are: kWh (there's usually dot between the "kW" and "h" but I couldn't be both typing it) - http://en.wikipedia.org/wiki/Kilowatt-hour. Over the years you've written all sorts of variations of this- from memory sometimes KWHR, KW/H, etc. And even though this has been explained to you more than once previously you to still (as of this morning for example) write it wrong!
Getting your units correct (and more generally proper use of common technical terms like stain, stress, force, field, work, energy, etc.) is a shibboleth for people educated in scientific fields. Correct v's incorrect usage is one of the best/fastest ways to see if someone actually knows what they're talking about. Understanding units and measurement is so important that students of science/engineering typically do a lectures devoted specifically to this. Dimensional analysis is a very cheap/fast check that your calculations/equations are not "not even wrong"- http://en.wikipedia.org/wiki/Dimensional_analysis and http://en.wikipedia.org/wiki/Not_even_wrong .
