What a funny question. No. The only time I use candles is when there is some power drop during the night. Honestly, I can't see any reason to save so much. I think this is a bit of an exaggeration in my opinion but, I'm not judging anyone (after all, save some money is always good ).
I cannot really say that I do, but that is mostly just a function of me not really having any around, but if I did I bet that I would do this more often. Light is light and if you can do with them for a good amount of time that means some savings.
Candles for saving money is great! Like many I too have a concern of fires, but if we are very careful, nothing should happen. What we do to save money too is to unplug. Even unplug the washer, we don't have a dryer, we rely on good old wind and sun for drying our garments, so we save money that way too. I have candles and battery powered flashlights fancy and useful ones too when something happens to our electricity. (I pray a lot so nothing happens to cable, internet, electricity, water, sewage things, gas things too, for we have had a lot of storms lately...so far so very good, thank God!)
It seems to ba an effective method for saving on electricity. However, I don't believe in utilizing this method for saving on electricity costs. For me, Installing LED bulbs would be the preferred thing to do and the danger of starting a fire would be also be eliminated.
I am not sure that I would use candles for the sake of savings on energy costs. They are a cheap way to add some ambient light to a room and make it romantic feeling, but I feel compelled to stay near my candles when they are burning. I have always been terrified about leaving a room where a candle is burning and it getting knocked over and catching the house on fire. Much more important for me to keep my house intact rather than save a few dollars on the electric bill.
Well I am not using candle to save on electricity bills the main reason being that I am not person paying for this utility. The fact as far as I am concern if the cost of electricity become exorbitant I wouldn't mind using candles sometime to save cost. I may use the candle more often when I am about sleeping thereby making sure all lights are put off. I may support this by also using rechargeable lamps
