How does an energy saving light bulbs work?
Energy saving light bulbs are fluorescent not incandescent. Over 80% of the energy consumed by an incandescent light bulb is converted to heat energy. Fluorescent bulbs produce much less heat, therefore a higher proportion of the electrical energy is converted to light energy, for the same amount of light output. If you don’t believe that, just feel the heat difference between an incandescent and fluorescent bulb. The law of conservation of energy states that energy can not be created or destroyed, it can only be converted from one type to another. However the law of entropy states that every time you do the conversion, some energy is “lost.” Therefore, in the winter time in a cold climate, the heat of an incandescent light bulb contributes to interior space heat, so they are not as inefficient in certain conditions as promoters of energy efficient bulbs would have you believe.
