Much attention has been given lately to global warming and the need for all of us, especially those of us in the United State and other industrialized countries, to conserve resources and reduce our contribution to global pollution. If you’re like me, when I hear the reports or read the accounts in newspapers or magazines, it still seems like something that needs to be addressed by someone else. Many of us have the tendency to think that what we do individually makes little difference. That of course is not true. Over the next two weeks I will give you some suggestions for saving electricity thus reducing pollution from our local coal fired generators. At the same time I’ll give you an added incentive, since you will not only be saving energy but be able to put a few bucks back in your pocket.
In any house there are visible and invisible consumers of electricity. Some will surprise you and you will be amazed at the amount of energy (and cash) you can save with just a few changes.
Among the most visible consumers of energy is lighting. Let’s look at household lighting and how to accomplish some significant savings.
I checked with my friends at Duke Energy to arrive at an average residential cost per kilowatt hour. In other words, how much does it cost to use 1000 watts of electricity for one hour? The answer, in the Greater Cincinnati Area including Indiana, but not Kentucky, is 10 cents. I will use that number to compute the cost savings throughout this article. If you don’t live here you will need to find out from your electric provider your KW/H cost.
With that in mind I did a little auditing of my own habits to see what impact I could have on reducing my own energy consumption and what that might mean for my utility bill. I have already changed out the bulbs in several lighting fixtures with highly efficient compact fluorescent bulbs. These new bulbs come in a variety of sizes with varying light outputs. Some can be used with dimmer switches. (Be sure to look on the package since not all will work with dimmers.)
Currently you can purchase compact fluorescent light bulbs that provide the same amount of light (or lumens) as a standard incandescent bulbs but use a fraction of electricity. Those bulbs will last 10 times longer. Let’s do the math. If you use a 100 watt bulb in a lamp in the family room and it is turned on an average of five hours per day (more in the winter, less in the summer) that will work out to 1,825 hours per year. If you use the regular incandescent bulb, it will consume 182,500 watts in one year ( 182 kwhrs) costing you $18.00. If you replace that incandescent bulb with a compact fluorescent bulb using only 23 watts per hour, you will pay $4.00 for the same amount of light for an annual savings on that single lamp of $14.00
If you look around your home, I bet you can find a dozen or more lighting fixtures that can be changed out with little effort and a modest expense. Even figuring in the higher cost to purchase each compact fluorescent light bulb, you will have a net cash savings at the end of the year. Each year thereafter will save you more than $150 if you change out 10 or 12 bulbs. The reduction in electric demand of course will lessen the need for Duke to burn coal to make electricity in the first place.
In the next post we will look at some less visible electricity “vampires.”
