This lesson was revised on May 31, 2024. Here is a link to the previous version.
In this lesson, students explore how a city's electricity is derived from natural resources such as coal, sunlight, wind, and water. They investigate how using these different energy sources affects the environment. In the activity, Power this Town, students obtain and combine information about different types of renewable energy, and evaluate the advantages and disadvantages of each energy source.

Prep Instructions

We suggest students work in pairs. Homeschool students can work on their own.

Set Up Classroom for Discussion

Place each Energy Sign in a separate area of the room so that students can easily see them.

Teacher Tip

Some classes may want to do research on the towns we featured in the readings. All of them are real towns, but we changed the name of one town. We called the solar-powered town in Florida “Ranchtown,” but the actual name is “Babcock Ranch.”
