If the current environment where fossil fuels are reaching a very high cost and energy bills are also skyrocketing, it might be worth looking a bit deeper and finding ways and means to save as much energy as possible.
One of the possible things is to learn a bit more about electricity usage and home appliances that use the most energy. In this way, you can characterize the energy usage and figure out a way to maximize the output and desired functions at a minimal cost.
If you want to save electricity it would certainly help to pinpoint and learn more about things that utilize the most, therefore costing you the most money. To give you some perspective, for example, if you are worried about your bill costs, it wouldn’t matter so much to worry about mobile chargers and LED light as they consume so less however your electric shower is something that you should take into account.
Every electrical appliance has a certain power rating which it requires to function properly, but as
The general rule, anything that converts electricity into Heat is something to keep eyes ON
It’s also the frequency of usage that matters, for example, an item like a refrigerator has a low electrical footprint, however, it is ON 24/7, and out of that, it shall be working to full capacity up to 50% of the time. On the opposite end of the spectrum, Electrical iron is very high in power but used only for a short period of time.
To understand a bit more, let’s do a simple calculation :
You are using a refrigerator with a power rating of 250W, equivalent to 0.25 KW.
If you run this device at full power for 24 hours => 0.25 KW * 24 H = 6 KWH
This magical 6 KWH is 6 units of electricity, and it is obtained by multiplying the power in KW by the number of hours it is used, hence KWH. 1 KWH is called one unit of electricity, the unit used by the power company to charge clients.
A Tariff is the cost scale used by a supplier to charge a particular customer. It comprises Electricity Unit ( KWH ) Price, Standing charge, and Time variation is the unit cost if available.
Taking it further, multiply the cost per Unit by the units and you will get the total cost over a period. As in the above example if the cost per unit is 25P then
Total cost of using refrigerator for 24/7 is => 6 KWH * 25P = 150 P or 1.5 £ .
We have done a basic electricity usage and cost calculator which should you understand some extent the power used by different devices and how you can control the cost of bills if possible at all. Bear in mind these are only estimates. Plugin the right Tariff values if you have them available but we have used the general and most common values where possible.
