Renewable and Nonrenewable Energy - Worksheet | Printable and ... - Free Printable

The image you've uploaded is a completed worksheet titled *"Renewable and Nonrenewable Energy (Worksheet) - Solution"*, which categorizes different energy resources into renewable and nonrenewable types based on visual icons.

Let’s go through the solution and explain it step by step:

---

🔹 Objective of the Worksheet:

To identify whether each energy resource shown in the pictures is renewable or nonrenewable, and to name the correct energy source.

✔ Renewable Energy Resources

These are energy sources that are naturally replenished on a human timescale. They are sustainable and environmentally friendly.

1. Biomass
- Icon: A growing plant
- Explanation: Biomass refers to organic materials like wood, crops, and waste from plants and animals. When burned or processed, they release energy. It's renewable because plants can be regrown.

2. Wind Energy
- Icon: Wind turbines
- Explanation: Wind is generated by solar heating and Earth’s rotation. As long as the sun shines and the Earth spins, wind will blow—making it renewable.

3. Solar Energy
- Icon: Sun and solar panels
- Explanation: The sun provides constant energy. Solar panels convert sunlight into electricity. The sun will continue to shine for billions of years, so this is renewable.

4. Hydropower Energy
- Icon: Dam with flowing water
- Explanation: Uses the movement of water (from rivers or dams) to generate electricity. Water cycles continuously via evaporation and rainfall, making hydropower renewable.

5. Geothermal Energy
- Icon: Geothermal power plant
- Explanation: Uses heat from deep within the Earth. This heat comes from the planet's formation and radioactive decay, which continues over long periods—so geothermal is considered renewable.

✘ Nonrenewable Energy Resources

These are finite resources formed over millions of years. Once used up, they cannot be replenished quickly.

1. Fossil Fuel Oil (Petroleum)
- Icon: Barrels of oil
- Explanation: Formed from ancient organic matter buried under pressure over millions of years. Not replaceable on a human timeline → nonrenewable.

2. Natural Gas
- Icon: Flame (gas flame)
- Explanation: Primarily methane, also formed from fossilized remains. Like oil, it takes millions of years to form → nonrenewable.

3. Coal
- Icon: Coal cart
- Explanation: Made from plant material compressed over millions of years. Once mined and burned, it cannot be replaced quickly → nonrenewable.

4. Nuclear Energy
- Icon: Nuclear power plant with radiation symbol
- Explanation: Uses uranium or plutonium, which are mined from the Earth. These elements are finite and not replenished naturally → nonrenewable.

🔄 Summary Table

| Type | Energy Resource | Icon Description |
|--------------------|------------------------|--------------------------|
| Renewable | Biomass | Plant |
| | Wind energy | Wind turbines |
| | Solar energy | Sun + solar panels |
| | Hydropower energy | Dam/water flow |
| | Geothermal energy | Geothermal plant |
| Nonrenewable | Fossil fuel oil | Oil barrels |
| | Natural gas | Flame |
| | Coal | Coal cart |
| | Nuclear energy | Nuclear plant + symbol |

✔ Final Answer:

The worksheet correctly matches each picture to its energy source and classifies them properly.

- Renewable: Biomass, Wind energy, Solar energy, Hydropower energy, Geothermal energy
- Nonrenewable: Fossil fuel oil, Natural gas, Coal, Nuclear energy

This classification helps students understand the difference between energy sources that are sustainable (renewable) and those that are limited and contribute to environmental issues (nonrenewable).
