#AP Environmental Science: Hydropower Study Guide ⚡

Hey there, future AP Environmental Science rockstar! Let's dive into hydropower, a key renewable energy source you'll definitely see on the exam. This guide is designed to be your go-to resource the night before the big day, so let's make it count!

#What is Hydropower?

There are two main ways to generate hydroelectric power:

• Dams: Using the force of water stored behind a dam.
• Tidal Waves: Capturing the energy of ocean tides.

#How it Works 🌊

Let's break down how dams generate electricity:

1. Reservoir Creation: Dams are built on rivers, creating an artificial lake or reservoir.
2. Water Release: Water is released from the reservoir through a pipe.
3. Kinetic Energy: As the water falls to a lower elevation, it gains kinetic energy (energy of motion).
4. Turbine Rotation: This kinetic energy turns a turbine, similar to a water wheel.
5. Electricity Generation: The turbine's rotation powers a generator, converting mechanical energy into electrical energy.
6. Distribution: The electricity is then sent to homes, businesses, and other buildings.

#Benefits and Drawbacks
