about 10,000 KWh
To find kWh a time frame has to be given. That is what the h in kWh stands for.
What it costs me to run a heater does not depend on how much you are charged, but a 1500 watt heater would use 1500 watt-hours or 1.5 kWh for every hour it is run. Run for 24 hours it would use 36 kWh, also known as 36 units.
About 11.75 cents per kWh for residential use (7.53 cents/kWh for industrial), as of September 2010:
In ten hours, a 200W bulb will use: 10 * 200 = 2000 Watt-hours = 2 kwh
I use about 50 KwH in a week or, at least, that's how much I pay for.
it takes up 3500 kWh
455.1 billion kWh per year
Not a lot. In fact only 1500 kWh
If it is a 100 watt bulb, this would take 2.4 KWh in a day and hence 876 KWh in a year. This would be the same whatever the source of the electricity
100 kWh
about 10,000 KWh
31,500 Kwh (UK) per annum
400 Kwh ( 120 Liter )
Multiply 75 kW by T hours of use = 75T kWh, which is how much energy the motor uses.
Typically you would use 0.276 litres/kWh for HSD and 0.234 litres/kWh for HFO
