Quite a few individuals don't really care about lighting because they believe that your light bulbs will not really consume lots of energy. Lights can have a large effect on your regular bills since they can up plenty of energy if they are used often. If you have been making use of incandescent bulbs, replace them with CFL or LED bulbs immediately.
This is definitely a big problem for the individuals who are not using solar or wind energy as alternative sources. They are pretty expensive until now so some folks think that it will not be beneficial to regular households.
