Geothermal energy uses heat from deep inside the Earth. In some places, hot water and steam come from underground. This steam can run turbines to make electricity.
It is clean, renewable, and available all year. Countries like Iceland and the USA use geothermal power a lot. It can also be used to heat houses and greenhouses.
The main problem is that it is only possible in areas with volcanoes or hot springs. Drilling deep into the earth also costs a lot. Still, where possible, geothermal energy is a very good way to get clean power.
This is a working model of a Geothermal Energy Power Plant.Water is pumped underground where Earth’s heat turns it into steam.This steam rises through pipes, rotates a turbine, and generates electricity.
The electricity is transmitted through power lines to homes and factories.
Geothermal energy is a renewable, clean, and sustainable power source.”
Video Step-by-Step Model Instructions:
Step 1: Create Earth’s Layers
- Take a large cardboard box and place it horizontally.
- Cut one long side open to reveal the inside.
- Draw or paste colored layers inside the box to represent:
- Crust (brown),
- Mantle (red/orange),
- Core (yellow/glowing effect).
Step 2: Add Geothermal Pipes
- Insert 2-3 plastic pipes/straws from the top of the box going down to the hot core layer.
- Label one as Injection Well (cold water in), another as Production Well (steam out).
Step 3: Build the Turbine System
- On top of the box, build a small power station building with cardboard.
- Inside it, fix a plastic fan blade (turbine).
- Connect the steam outlet pipe to blow air (or syringe push) to rotate the turbine.
- Optional: Attach a DC motor behind the fan blade to light up an LED when spinning.
Step 4: Add Cooling Tower & Condenser
- Beside the turbine house, create a cooling tower using a paper cone.
- Add a pipe from turbine to cooling tower.
- Use cotton to show steam flow (visual effect).
Step 5: Create Power Transmission
- Add 3–4 power poles using skewers or straws.
- Use thread/wire as transmission lines.
- Connect the wires to a cardboard house to show power is delivered to consumers.
Step 6: Decoration & Labeling
- Paint the Earth’s layers, steam pipes, and top structures.
- Label clearly:
- “Geothermal Reservoir”
- “Injection Well”
- “Production Well”
- “Turbine”
- “Generator”
- “Cooling Tower”
- “Power Lines”
- “Home/Factory”
