Right now we are being pelted with rain from Frankenstorm Sandy - we have had rain since yesterday and will be having rain at least through Monday - and we have a finite amount of clothing.
As much as I don't like to use my dryer, I do have to make sure we have plenty of clothes to get the job done, so I do medium sized loads and set my dryer to low . Then they are done in about 30 minutes, which is about half the time required as large loads (plus being as low burns less energy too). I can get by with about 1 load a day this way, sometimes 1 every other day until the rain stops, then I can catch up on sheets, blankets and towels then.
Plan your laundry, do the necessities, don't wash things that aren't actually dirty and you will be able to be a little more conservative when the dryer is your best option.
