I believe that inventions such as the light bulb, using natural reasources for our benifit, were very important. Everywhere you look, light bulbs are being used in some sort of fashion, like street lamps of car headlights. I have once been in a power outage for about three days. It was hard to do normal everyday things without electricity. This has become so much as part of our lives that it is hard to imagine living without it.
