Grade level: 2nd – 3rd grades

Environmental Area: Energy

Purpose: Understand primary energy sources in our country and develop awareness of our energy use

BACKGROUND FOR THE TEACHER

Our country produces and consumes the world’s second largest amount of energy, second only to China. Primary energy consumption in the United States in 2019 was 100.2 quadrillion BTUs (U.S. Energy Information Administration, 2020).
