I will admit, I love my clothes line! There it is public knowledge now and I have no problems with it. I have a clothes line in my back yard and have had one for about five years. I am actually on my third umbrella type clothes line and finally invested in one that has been wonderful and stood up to the tests.
I remember being asked one day by a friend why I used a clothes line. First, I love the smell of the blankets and sheets after they have hung outside to dry. And for the other clothes, I still love the freshness. But second, it was always contradictory to me to be trying to cool a home with air conditioning and heating it up using a dryer (or a stove or oven for that matter). So it made complete sense to the engineer side of me to begin using a clothes line and save the wear and tear on the air conditioning system and save some money on the electric bill. I remember the first month using a clothes line my electric bill dropped $30 in the middle of summer!!
So, today as I was hanging out clothes, I decided to do some calculation and find out what it costs to dry a load of clothes in a clothes dryer. At Energy.gov there is an explanation on how to calculate out the energy usage of appliances. Also some energy companies provide an online calculator for energy usage.
I found my dryer pulled 30 Amperres of energy on a 240 V circuit. (I googled the brand and model and found the specifications online.) I also visited the website for Black River Electric Cooperative in Sumter and looked at my bills and did some calculations and found it is approximately $.11 per kWH of electricity.
From that I calculated:
(30A X 240V) X $.11 X time in hours for a load = cost per load
My dryer worked out to $.79 per load.
So let’s say I dry six load a week four weeks a month, that works out to be $18.96 per month. That is for the dryer only, it doesn’t include the impact of heating the house up and cooling it back down!
