Purpose: Understand daily per capita primary energy consumption in our country compared to other countries and develop awareness of our energy use
BACKGROUND FOR THE TEACHER
The United States and China are the two countries with the largest wind power generation capacity in the world. Our nation had the world’s largest wind power capacity in the 2000s. However, its capacity was surpassed by China in 2010. Together, our country and China produced about half of the world’s wind energy in 2019 (IRENA, 2020).
The purpose of this activity is to enhance students’ skills in interpreting line graphs with 2 series. The graph compares wind power capacity in our country and China for the last 10 years. The data was obtained from the Global Wind Energy Counci (GWEC, 2018)and U.S. Department of Energy.
worksheet & Answer key
Using a table that shows cumulative wind power capacity in the United States and China between 2009 and 2019, students are asked to compare 3-digit numbers and add/subtract 3-digit numbers to find out how the two countries increased their wind capacity over the last 10 years.
