Abstract

Has your house (or one of your friend's houses) been remodeled recently? Were any improvements made for energy efficiency (solar systems, better insulation, passive solar heating, better lighting)? Compare your family's energy costs for a similar time period before and after the remodeling (remember that energy usage often varies seasonally). Monthly bills often have a bar graph showing energy usage for the previous 12 months. You may also be able to get information on past energy usage through your electric company's website. Ask your parents for help to access the online records. Did the improvements save you money? Analyze the cost of the remodeling work that was specific to energy efficiency (for example, if your house got a new roof, and insulation was added, find out what was the extra cost for the insulation, don't use the entire cost of the roof). Calculate how long it will take for the energy savings to pay for the improvements.

Career Focus

science career image If you like this project, you might want to think about career opportunities in Environmental Engineering.

Environmental engineers plan projects around their city or state—like municipal water systems, landfills, recycling centers, or sanitation facilities—that are essential to the health of the people who live there. Environmental engineers also work to minimize the impact of human developments, like new roads or dams, on environments and habitats, and they strive to improve the quality of our air, land, and water.
