Calculating the energy usage in your home is a relatively simple mathematical process. All you need to calculate the energy use of your home appliances is to find out what the wattage is and then combine it with how long it is used, but it isn’t that simple. This can be an experiment fit for a whole day off or a weekend without any plans. The unit of measure that combines the wattage of an appliance and the time used is called a kilowatt. Here is how to calculate the energy of your home appliances.
First you need to find out what the wattage is of a particular appliance. Sometimes this can be more difficult, because the manufacturer won’t usually include the number right on the appliance. You might be able to look underneath the appliance, but if you can’t find anything, it is recommended to call the manufacturer and ask. A representative will be more than happy to provide you with this information. In addition, you might want to keep a notebook on hand to keep a detailed list of all the appliances you want to measure.
Next, with the notebook you want to jot down how much time you use the appliances you want to measure. This could take a day or two, because many people don’t know offhand how long their TVs or computers are left on each day. Moreover, you might have a few appliances that use different levels of wattage when on standby. For instance, a charging computer will use a certain amount of watts when charging than it does while being used. So, you want to time how long it takes to charge your appliances as well.
After you have a detailed list of wattage versus time used, it is time to whip out a calculator. All you have to do is multiply the hours used by the wattage of the particular appliance. For instance, if you use your computer for 5 hours a day at about .05 watts – this comes out to be roughly 1.75 kilowatts per week. If you start to add up all your appliances, you might be a little shocked – no pun intended. Things like refrigerators and water heaters might top the list of the most energy used in a week, according to environmental data resources If this is the case, you can employ a number of different energy saving methods to keep your utility bills down and your carbon footprint to a minimum.
Lastly, by looking at your utility bill you can also find out what your energy provider charges per kilowatt-hour. This way you can devise a financial plan for cutting down your energy usage, which could save you a lot of money. While you probably don’t want to sacrifice your morning shower, you might want to shorten it to a reasonable amount of time – say 5-10 minutes. Once you find out that each shower you take costs as much as your morning soy latte – you might think differently.
