One of the most difficult deliberations when you decide to install energy efficient light bulbs in your home is cost. Since each energy saving light bulb will cost you around $5 each, it is smart to stop for a moment and ask yourself what your Return On Revenue (ROI) will be.
I came across a very smart tool to help you decide if installing energy efficient light bulbs in your home is financially viable for you. This calculator I found over at the GE Lightning site and it is called the Smart-CFL Savings Calculator. It is reasonably based on 4-hours of bulb usage @ 10c/kWh.
By simply swapping out 4 100-Watt standard light bulbs with 4 x 26-Watt energy saving light bulbs, it is calculated that indeed over 1 year you will be saving $42.22. The reason I used 4 x 100-Watt bulbs as an example is only because that is how many we have in our bedroom.
I took stock of how many 100 and 60-Watt bulbs I have in my home. 25 x 60-Watt bulbs and 40 x 100-Watt bulbs. Based on the GE Calculator (and my own), replacing all of them with energy efficient light bulbs will cost me $325, considering one bulb runs about $5 each. Most interestingly the yearly electricity cost saving will be $625 per year.
To calculate your ROI for installing energy saving light bulbs, let's look at how to calculate it: ROI= [(Payback - Investment)/Investment)]*100 [(625-325) / 625)] * 100 48%
After doing the calculations it became clear to me that upgrading to energy saving light bulbs will be a financially smart move. In our first year we will see a ROI of 48% - not bad indeed.
If you think that the the average home has between 50-100 bulbs and that changing one 100-Watt bulb to an energy saving light bulb will save you around $10/year, it quickly becomes clear how this will be one of the best investments you can make for your family.
