Abstract
In the U.S., lighting homes and businesses accounts for 22% of all electric power consumption (Raloff, 2006). That's $55 billion worth of electricity, or the output of 100 large power plants (Raloff, 2006). How much energy could be saved by switching home lighting from incandescent to more efficient fluorescent lights? Conduct a survey to find out what types of lighting are used in homes in your area. Come up with an estimate of how many light fixtures are used in an average home, what types of light source (regular incandescent, halogen, fluorescent). Do background research to find out the relative efficiency of different types of lighting. How much energy could be saved by replacing incandescent lights with more efficient alternatives? Taking into account the cost of the lamps, how much money would be saved (if any)? You might also want to look into new lighting technologies like LEDs (Raloff, 2006; NGLIA, 2005). Could future light sources offer even more savings? (Idea from Langiewicz, M.T., 2004)Bibliography

Nuclear Engineer Nuclear engineers harness the power of the atom to help solve large and difficult problems facing humanity. They design power plants that create energy to power homes and businesses without producing greenhouse gases. They develop machines that image the human body and destroy cancer cells, sterilize food and medical equipment, and create new pest or drought-resistant seeds. They work to make the world a better place. |

Power Distributors and Dispatcher Think of all the things in your home or school that use electricity, like the lights, TV, refrigerator, washer, microwave, music players, computer, and electronic devices. Now think of how you feel when the power goes out, even for just a moment. Power plant distributors and dispatchers have an important job—they work to keep electricity flowing to homes and businesses by carefully watching and planning for problems like big storms that could damage transmission lines, heat waves that cause a big surge in demand for power, or normal construction work, which could take transmission lines out of service. | |

Power Plant Operator No matter what time of the day or night, or what the weather is like, power plant operators work to ensure that homes and businesses have a reliable source of power. They switch the plant generators on and off, as needed, and monitor and maintain generators, turbines, and pumps to prevent failures. |

Nuclear Power Reactor Operator One in five United States homes and businesses is powered by nuclear power, and nuclear power reactor operators are the people who ensure that those reactors are operating safely and efficiently at all times. They monitor all equipment continuously, and implement procedures if malfunctions are observed. They also control and adjust the amount of power being generated, and the reactor coolant temperature as power demands change through the day and during weather events, like heat waves. | |
