kwh is Kilo Watt Hour i.e. 1000 Watts of power used for one hour.

Take the wattage rating of the device and multiply by number
of hours used per day and then by number of days in a month
and you get the Watt Hour. Divide that by 1000 and you get the
kwh used in that month.

This assumes that the device draws the same amount of power
all the time (not necessarily true!) and hence, will give you
an approximate figure. But, it's good enough.

Your electricity bill has three parts: service, usage and
taxes. Your bill could have gone up if any of these three
went up.

Of course, the more you use electricity, the more your usage
charges. When you reduced your electricity usage from 16 hours
to 14 hours, then something else must have occurred at the
same time for your bill to go up. But, your usage charges for
tank lighting should have gone down. (You could have put up
your x-mas lights up around the same time, for example)
