In looking at my energy-related expenses I found the EnerGuide site interesting , particularly their interactive energy cost calculator. I have been considering setting up a small clothes-drying area in my basement and really wanted to understand, as nearly as possible, what I pay to use this on a per load basis.
Using their tool my dryer cost came out to be about $94 annually. Assuming we do 4 loads/week that's about $0.45/load. Not terribly significant, and this cost is arguably bordering on the 'non-essential but life-enhancing' (to use Derek Foster's terms). While I can have dry clothes whether I pay $94/year or not, it will probably take 10 minutes for my wife or I to hang it all up. And at $0.45 per load (assuming my math is right) it doesn't seem worth it. Frugal = good, miserly = bad.
Plus, putting on a pair of jeans fresh from the clothesline, something akin to cardboard lined with sandpaper, in no way compares to the oddly instinctive pleasure of donning the same pair fresh from the dryer. Its all about the simple pleasures.
