There are primarily two types of energy meter in the world of today and while one of these is installed in relatively older houses, there are those that are newer and new types of energy meter are installed here. Technology has made it possible to deal with the energy in a manner where energy is preserved and saved and where it can be used in the least expensive way but yet in the most effective manner.
One of the two types of energy meter is the single rate meter which is mostly used in old homes and/or third world countries. These types of energy meter result in the outcome of expensive electricity bills and high energy demands. Basically, what happens with such meters is that the rate is pretty much the same for everything and so the charge per unit is standard regardless of what appliance you are using in your house and when you are using it because that is simply how these operate. The disadvantage is that if someone uses the appliances at an hour when others are not using electricity or appliances in the same vicinity (with the same meter) that will not matter because the rates would be standard for everything at all times of the day.
Then, there are off peal meters. These types of energy of meter have one advantage that the single rate meter does not and this is this- if you use electrical appliances at those times of the day when others are not consuming much electricity, your cost per unit will be decreased and so, your bills would be a lot cheaper as well. If you take the total amount and add all the costs per unit you would see that the bill would probably come out to be half as expensive. These types of energy meter are used in countries such as Australia and the United States where energy retailers provide and install both types of energy meter. However, you would have to educate yourself about the types of energy meter your household may be using. You could even get the off peak meter installed if you want to but if you go for the single rate meter, you don’t need to get these installed provided you know how to use them. As a single rate meter, the main disadvantage is that the bill would still be more but if you used your electric
al appliances less at certain times of the day, your bills would come down by a lot too.
The electricity charge per unit is applicable upon the appliances you are using and so, that is what either of the two types of energy meter take into account, record and then, that is how the energy bill comes out to be what it is. The point of increasing costs per unit during certain times of the day is to encourage use of less electricity at certain times and hours of the day and to use electricity only when need be.
