There are some individuals who do not actually care about the lighting as they firmly believe that the bulbs are not taking in a lot of energy. You should know that your light bulbs can actually increase your monthly bills because they up plenty of energy. If you have been using incandescent bulbs, substitute them with CFL or LED bulbs immediately.
If you still incandescent bulbs, you must try changing your light bulbs. These bulbs normally discharge 98 percent of the energy that they up into heat so you must consider CFL or LED bulbs.
