I live in South Africa and you may know that our supply of electricity from
our monopoly supplier cannot meet demand so we are forcibly rationed with
rolling blackouts (which means we all have turns to have whole suburb's
supply cut. I want to save electricity but I need to measure it first and
record it and then compare to previous usage to see if I am indeed saving. I
need a template that will allow me to enter my daily usage (I will take a
reading at the same time everyday) and then build up a history so that I can
see which days heaviest usage occurs (and why!) over months and hope to see a
downwards trend. Also, it would be great if the template could predict costs
by allowing a price to be entered for usage and so one could see costs per
day, per week and per month. It would be nice if the template had graphs for
days, weeks and months with usage and cost.
