Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the nexus conceptualization?Initiated by Peter Gleick's 1994 life-cycle analysis of energy production's water footprint
2. What is the primary water consumer in energy?Thermoelectric power generation, mainly for cooling purposes
3. What does "water-energy nexus" mean?It means water and energy depend on each other. Water is needed for many kinds of power, and energy is needed to move and clean water.
4. Why do power plants need a lot of water?Most power plants use water to cool the steam that makes electricity. They take water from rivers, lakes, or oceans, use it to condense steam, then return it, sometimes warmer.

Water-Energy Nexus: The complex interdependencies between water systems and energy production, consumption, and infrastructure.
Life-Cycle Analysis (LCA): A methodology for assessing the environmental impacts associated with all stages of a product's life.
Energy Intensity (EI): The amount of energy required to produce or deliver a unit of a good or service, in this context, related to water.
Thermoelectric Power: Electricity generated from heat, typically involving steam turbines, which are highly water-dependent for cooling.
