not sure you are right to use kWh - kW yes, but not kWh
He's right ... 80 watts x 12 hours = 960 watt-hours = 0.96kWh
I agree with you! Absolutely but the previous person said, "12h a day is
near enough 1kWh". It isn't - it is 0.96kWh
Not trying to be pedantic - but it makes a big difference if you start to
cross reference to other information.
Lesson:
1 Kilowatt running for one hour is 1 kilowatt hour.
500 watts running for one hour = 0.5 kilowatt hour.
1 kilowatt running for 30 mins = 0.5 kilowatt hour
&
80 watts x 12 hours = 960 watt-hours = 0.96kWh
??????????? Durrrr .... Which is "near enough 1 kWh", exactly as stated
