Assuming 100 kw bulb
We'll start by figuring out how much energy in
kilowatt-hours the light bulb uses per year. We multiply how much power it uses
in kilowatts, by the number of hours in a year. That gives 0.1 kW x 8,760 hours
or 876 kWh x 9 bulbs = 7884 kWh
The electricity produced by 4 tons x 2460
kWh/ton = 9840 kwh
Since the produced electricity is bigger so it
is enough
