Understanding the relationship between water, energy, and electricity generation is vital for making important decisions. The energy sources we use to power our homes are constantly evolving, especially today in the midst of an energy transition. Decision makers must take water resource supply and demand into consideration to ensure we will not face water scarcity in the future.
Design Challenge
This design challenge will allow you to take the opportunity to work through these challenges and important decisions on your own! In Part 1 of the Design Challenge, you will be asked to work through an activity sheet that calculates how much water Texas uses annually1based on 2020 ERCOT numbers for electricity generation. Next, you will envision a fuel mix based on proposed market demand drivers that favor natural gas, wind, and nuclear. You will go through the same calculations to determine projected water use based on this anticipated scenario.
To begin, click on the button below and walk through the activity sheet to complete Part 1 of the Design Challenge. After you finish working with the activity sheet, complete the review questions below to assess your learning.
