No Brainer Energy Tips – Light Bulbs

Conserving energy has become an ever increasing concern as prices keep climbing.  One of the easiest places we can conserve energy (and save money) is by changing our light bulbs.  No, this will not end our dependency on foreign oil or make us rich, but every watt conserved really adds up if we all pitch in. 

Consider this, a 60 watt incandescent light bulb costs about $1.50 and will last about a year.  A mini fluorescent light bulb uses 14 watts, costs $5 and will last about 7 years.  Even though the initial cost may seem higher for the fluorescent bulb, the savings over the 7 year life is $5.50.  The fluorescent bulb also uses 1/4 of the energy for the same amount of light reducing the cost to operate that bulb. 

While the fluorescent light is on the temperature is about 120 degrees.  Compare that the the incandescent bulb at 320 degrees.  By switching to the fluorescent light, we reduce the amount of heat being released inside our home.  In the summer, we are trying to remove heat from inside the home.  We do this by running the AC which also costs money.

So if we switch our light bulbs from incandescent bulbs to fluorescent bulbs we will save money on the bulb itself, save money in the operation of the bulb over its life time and release less heat into the home that we have to pay to remove by running our AC.

Hmmm, No brainer energy tip.

P.S.  That’s also more time watching football instead of changing light bulbs.

    How would you rate halogen light bulbs?

    Hi Joe – thanks for your question.
    Halogen light bulbs and regular light bulbs (also known as incandescent bulbs) are similar – they both create light through heat. In fact about 90% of the energy they emit is in the form of heat. The only way to reduce the heat emitted by incandescent and halogen bulbs is to use a lower wattage bulb.
    On the other hand, both compact fluorescent bulbs and fluorescent tubes contain a gas that, when excited by electricity, hits a coating inside the fluorescent bulb and emits light. Therefore, they’re far more energy-efficient than incandescent or halogen bulbs. The fluorescent bulbs used in your home only emit about 30% of their energy in heat, which makes them much cooler.

    Thanks for responding. BTW: The cost of these light bulbs are down to less than $1.99 per bulb. Changed all of them this past week.
