Before we see how much electricity costs in ours homes, we have to understand how it's measured.

What the heck is a kilowatt hour?

1º Watts

The rate of electrical use at any moment is measured in watts. For example, a 60-watt light bulb uses 60 watts or a air conditioner uses about 3400 watts

2º Watt-hours

To know how much energy you're using you have to calculate how long you run your appliances. For example, when you run a 100-watt appliance for an hour, you have:

100 watts * 1 hour = 100 watt-hour or 0,1 kw-hour

Example 2º

seven 100-watt light bulbs on for two hours, is 1,4 kWh (7 bulbs x 100W x 2h= 1400Wh = 1,4 kWh)

Example 3º

Running a 3400-watt air conditioner during 3 hours is 10.2 kWh.

How much does electricity cost

The cost of electricity depends on  how much you use, and possibly when you use it ( day or night).

 Fixed charges that you pay every month no matter how much electricity you use. An electric meter  is a device that measures the amount of electrical energy supplied to a residence . The electricity company rents  you a meter in order to measure the electricity used in your home. It is about 57 cents per month  just for the privilege of being a consumer of electricity, no matter how much electrical energy i use, i have to pay for about 6 euros per month. this money is for the  maintenance of all cables,  pylons,  electrical transformers, etc.
