The energy efficiency of your home is actually something that needs a lot of attention. Of course, installing different energy efficient devices will help to achieve the reduction of energy bills, but it is not the only thing that matters. If you are really interested and determined to conserve energy in your home you should also keep an eye on the amount of energy used. To be informed on this topic you should be informed about your many electronic devices. Determining approximately how much electricity is actually used is really easy.
You can use this formula to estimate an appliance's energy use:
(Wattage × Hours Used Per Day) ÷ 1000 = Daily Kilowatt-hour (kWh) consumption
1 kilowatt (kW) = 1,000 Watts
Usually on each electronic device the amount of watts it uses is printed on itself or on a nameplate, stamped on the back or bottom. You can also figure it by multiplying the drawn current (amperes) by the voltage. Pay attention that the wattage shown on the device is a maximum, so it actually used less watts unless you have them turned up to maximum power.
The greatest amount of electricity is typically used by the water heater ( f. e. 40 gallon water heater uses nearly 4500-5500 Watts,) that’s why installing solar water heaters is becoming more and more popular and efficient. This topic was discussed on our blog earlier.
When calculating the amount of energy used by your electronic devices do not forget to factor in time of use. Many appliances continue to draw a small amount of power when they are switched off, such as VCRs, televisions, stereos, computers, and kitchen appliances.
After providing this research you’ll know the usage of which appliances you should reduce, and maybe it is possible to switch them to more energy efficient products.
