ENERGY HOW MUCH ENERGY DO I USE IN MY HOME IN FIVE SCHOOLDAYS?

LAMPS

I have counted all the lamps I use in my house in five schooldays. Totally I use twenty lamps in one day. I use eight of them in 4 hours/day and each of those lamps use 60W. I use 6 of them in 2 hours/day and each of them use 40W. And I use 6 of them in 5 hours/day and each of them use 10W.The lamps I use in 4 hours/day uses 9.6 kwh in five days. The lamps I use in 2 hours/day uses 2.4 kwh in five days. And the lamps I use in 5 hours/day uses 1.5 kwh in five days. Totally all the lamps uses 13.5 kwh.

COMPUTER,TV AND MOBILE CHARGER

When the tv in my house stands on standby it uses 0.24 kwh. I use the TV in 2.5 hours in five days. And when i use it the tv uses 0.85 kwh. The tv totally use 1.09 kwh in five days.

The computer just uses energy when I load it. It uses 0.065 kwh.

The mobile charger uses 0.005 kw/hour and I use it in four hours. So the charger uses 0.02 kwh.

THE WASHING MACHINE &THE VACUUM CLEANER

Our washing machine use 2.7 kw every time we use it. And we use it 3.9 hours/week. So the washing machine uses 10.53 kwh.

In five days I use the vacuum cleaner in one hour. The vacuum cleaner uses 1.5 kwh.

THE SHOWER

I use the shower three times on five days and every time it uses 7938000 J.

It is the same as 2.205 kwh.

HOW MUCH ENERGY DO I TOTALLY USE THEN?

I have summarized all the energy I use and it became 28.91 kwh.

So in five schooldays I use 28.9 kwh.
