In a place such as Canada, sometimes it is quite inconvenient to hang our clothes outside to dry because the weather can be quite unpredictable. Although I read that letting our clothes hang dry outside keeps our clothes fresh and preserves the color longer, I am usually worried about the sudden change of weather all in one day's time. One moment it could be sunny and before the end of the day it could start raining. If we didn't watch the weather forecast for the day, then we sometimes end up with more wet clothes. In the winter, all the clothes hanging will be done indoor which require lots of space.
On the other hand, using an electric dryer could be quite damaging for the clothes in the long term. That's what I read about on the internet. The clothes don't last longer and the color fades faster as compared to hanging clothes to dry. Wear and tear appears much earlier on the clothes and it doesn't smell as fresh after using the electric dryer to dry clothes.
