A watt (W) it is a unit used to measure power.
A Watt it is the amount of energy that our household appliances and devices need to function, the rate at which they consume energy.
One watt is the equivalent to electricity flowing at a rate of one joule per second.
For example, a light bulb rated at 60 W will need that much amount of power to be able to produce a predetermined amount of light (lumens).
The following video explains what a watt is and how it is related to other power measurement units and our household appliances and devices. Do not forget to enable the video captions, as the video caption contains the concepts explanations.
This calculator can be used to:
kW = W/1000
kWh = (W/1000) x Hours
kWh is the measurement unit used by the electricity suppliers to calculate our electricity bills.
Also, most of the big appliances, like the dishwashers or washing machines, rate their consumption in kWh.
A few other examples from our ‘Electricity usage calculators‘ page that may be of your interest:
A very practical way to find out how many watts, kilowatts or kilowatt hours of electricity do our household appliances use, it is to use a plug in power meter.
A plug in power meter do also measure the exact electricity cost over time so this device can be used to find out how much you are paying and find any appliance or device which may be wasting electricity.
Energy conservation can be defined as the decision and the act of using less energy
Energy conservation both benefit you and the environment
The act of saving and conserving electricity does benefit you because you will be paying less on your energy bills.
And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.
Now, at individual level it may not look worth to try to save a few watts here or there.
Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.
For example, if 9000 households would manage to save as little as 10 Watts per hour (0,01 kWh) worth of electricity per day, that would add to 32850 Kilowatt hour (kWh) per year.
That is a considerable amount of electricity, but let’s add additional perspectives for clarity:
In any case it is clear that small energy savings do really count when looking into the bigger picture.
