In this video, we show you how to build a renewable energy working model that combines solar power and wind energy to demonstrate how clean, sustainable energy can be generated and used to power small devices like LED lights or model houses.
This working model is ideal for school science exhibitions, science fairs, classroom demonstrations, and renewable energy projects because it shows real concepts with simple materials and easy assembly steps.
With increasing environmental concerns and depletion of fossil fuels, renewable energy sources like solar and wind energy are becoming vital for a sustainable future.
Solar energy comes from the Sun, while wind energy is generated by moving air. Both sources are clean, abundant, and non-polluting, which makes them excellent alternatives to coal, oil, and gas.
This model helps students understand how these energy sources work and how they can be used to generate electricity without harming the environment.
In this video you will learn:
✔ How to make a solar energy section with solar panels
✔ How to make a wind energy section using a wind turbine
✔ How both sources can generate electricity
✔ How to connect LEDs to show power output
✔ Explanation of renewable energy concepts for exhibitions
Materials You’ll Need
- Cardboard or base board for mounting components
- Small solar panel(s) to capture sunlight
- Mini DC motor with blades (wind turbine)
- LED lights or small bulbs to show electricity generation
- Wires, battery or connectors
- 9 V battery (optional) if you want storage or backup
- Glue, scissors, paper, markers for decoration
- Solar panel mount and wind turbine stand (cardboard/wood)
How the Model Works
Solar Energy Section
First, we make the solar energy part of the model. A small solar panel is fixed on a cardboard base, tilted to face the light source (sunlight or a lamp). As sunlight hits the panel, it converts light energy into electrical energy. When you connect the panel to an LED light or a small motor, the LED will light up, showing how solar power generates usable electricity. This part of the model helps explain how solar panels on rooftops or in solar farms power homes and devices.
Wind Energy Section
Next is the wind energy part. We build a mini wind turbine by attaching blades to a small DC motor. This turbine is fixed on a stand beside the solar panel. When wind or airflow (from a fan or by blowing) makes the blades spin, the motor generates electricity. This electrical output can also light up an LED or power another small device. This demonstrates how wind turbines in real wind farms capture kinetic energy from moving air and convert it into electrical energy.
Combined Output
You can connect both the solar panel and the wind turbine outputs to a single LED or multiple LEDs. When exposed to light and wind simultaneously, both energy sources generate electricity. This shows how hybrid systems work — combining solar and wind energy for continuous clean power, even if one source is weak at times.
Educational Explanation
This model teaches several important concepts:
- Energy Conversion: Solar panels convert sunlight to electricity; wind turbines convert wind to electricity.
- Renewable Energy Benefits: These sources are renewable, clean, and sustainable, meaning they don’t run out and produce no harmful emissions.
- Real-World Applications: Solar farms, rooftop solar systems, and wind farms power homes, industries, and even cities around the world.
This project not only makes learning fun and interactive but also raises awareness about environmental conservation and the importance of clean energy. For your science exhibition, make sure to label each section, explain how each component works, and show how LEDs light up with real renewable energy
