Kilowatt-hour = kilowatt x No. of hours used
Here, 2000 W = 2000 watts = 2000/1000 = 2 kilowatts
No. of hours used = 1 hour
Hence,
Kilowatt-hour = 2 x 1 = 2 kilowatt-hours
Ans: 2 KWH

2 kilowatts per hour.
In an hour it will use 2 kilowatts. ( which is 2 kilowatt-hours of electricity).
This is usually expressed as Kw/hr so if you know how much your electricity costs "per Kw/hr" you can calculate the running cost.
For instance I think I am something like 7 pence per Kw/hr so for me, the answer would be about 14 pence. Hope this helps.

Rather that kW's the unit kWH's is used to measure electrical consumption. 1 kWH = 1 kW for 1 Hour, makes calculations a lot simpler.
Electricity is charged at (around 7.5p per 1kWH)

It's 2 kWh - that's 2 kilowatt-hours and NOT 2 kW/hr (kW per hour). kW/hr is not a unit of energy, but kWh is.

energy =power *hour
therfore energy consumed is 2000*1hr/1000=2kwhr

2kW = 2000W therefore 2kw/hrs
