Simple calculation of cost of hydro.
Excuse my terminology hydro here in Ontario is electrical power. I learned on this site years ago the simple calculation for cost of electrical power for an appliance etcetera. It is a simple formula that has been lost to me. All those hits to the head have caught up to me 40 years later.
I.E. a 60 watt bulb used for x amount of time at 0.11 cents per kWh = $0.00
Thanks for reminding me. If anyone has kids let them take piano lessons, don't buy them skates.
