Abstract
In the United States, lighting for homes accounts for about 14% of all residential electricity usage (EIA, 2014). That's billions of dollars worth of electricity per year. The U.S. has passed legislation to phase out older, more inefficient incandescent light bulbs, and they are being replaced with newer, more-efficient bulb types like compact fluorescent lights (CFLs) or light-emitting diodes (LEDs). How much energy (measured in kilowatt-hours [kWh]) and how much money could be saved by switching home lighting from incandescent bulbs to more-efficient lights?
Conduct a survey to find out what types of lights are used in homes in your area. Come up with an estimate for how many light fixtures (floor lamps, table lamps, ceiling lights, etc.) are used in an average home, and what types of light bulbs they use. Do background research to find out the relative efficiencies of different types of lighting. How much energy could be saved by replacing incandescent lights with more-efficient alternatives; or, if people in your area have already made the switch to more-efficient options, how much energy did they save? Based on the cost of electricity in your area (ask an adult to look at their electric bill), how much money could be saved?
Do you have specific questions about your science project? Our team of volunteer scientists can help. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot.
How much energy do you think all the houses and buildings in the United States consume? It turns out they eat up 40% of all the energy that the U.S. uses in a year. The figure is high because all those houses and buildings need to be heated, cooled, lit, ventilated, and supplied with heated water and electricity to run all sorts of electrical devices, appliances, and computers. Energy efficiency engineers help reduce the energy that houses and buildings use. This saves families and businesses…

Every country has resources—people, land, raw materials, capital, and machinery—and economists study how those resources are distributed to create the goods that people buy, and the services people need or want. In their studies, economists monitor economic trends and collect data on things like energy costs, inflation, interest rates, exchange rates, business cycles, taxes, and employment levels. Based on their analysis of this data, they develop forecasts of economic activity so…

Are you passionate about the environment? Do you like developing and implementing new ideas? Do you enjoy talking with people about how humans impact nature? If these things are true about you, then you may be the ideal candidate for a job as a sustainability specialist. Sustainability specialists work in large and small corporations and universities to design and execute energy and resource conservation programs that reduce their employers' impact on the environment. This is a great career for…
