Educational worksheet for identifying renewable and non-renewable energy sources.

Since I can't view or access images directly, I can’t see the specific content of your uploaded image. However, based on your description and the text you've provided, it appears to be a worksheet titled "Renewable and Non-renewable Energy" that asks students to classify various energy sources into two categories: renewable and non-renewable.

Let me help you solve this task step by step, assuming the image contains the same information as described in your text.

🔍 Task Overview

You are given a list of energy sources:
- coal
- wind
- nuclear
- sun
- fossil fuels
- natural gas
- biomass
- petroleum
- hydropower
- waves

You must classify each as either renewable or non-renewable, and then match them with corresponding pictures (e.g., sun, wind turbine, oil barrel, etc.).

✔ Step 1: Understand the Definitions

- Renewable Energy Sources: These are naturally replenished on a human timescale. They are sustainable and environmentally friendly.
- Examples: Sun, wind, water (hydropower), waves, biomass.

- Non-renewable Energy Sources: These are finite and take millions of years to form. Once used up, they cannot be easily replaced.
- Examples: Coal, natural gas, petroleum, fossil fuels, nuclear (uranium).

> ⚠️ Note: Nuclear energy is often classified as non-renewable because uranium (the fuel) is a finite resource, even though the energy output is high.

✔ Step 2: Classify Each Source

#### 🔹 Renewable Energy Sources:
1. Wind – Naturally occurring air movement; endless.
2. Sun – Solar energy is constant and renewable.
3. Biomass – Organic matter (like plants, wood, waste) that can be regrown.
4. Hydropower – Water from rivers/lakes, replenished by the water cycle.
5. Waves – Generated by wind and tides, continuous.

#### 🔹 Non-renewable Energy Sources:
1. Coal – Fossil fuel formed over millions of years.
2. Natural Gas – A fossil fuel, limited supply.
3. Petroleum (oil) – Fossil fuel, not replaceable on human timescales.
4. Fossil Fuels – This is a general category including coal, oil, and gas.
5. Nuclear – Uses uranium or plutonium, which are finite resources.

> 📌 Note: "Fossil fuels" is a broad term that includes coal, petroleum, and natural gas. It's listed separately here but overlaps with the others.

✔ Step 3: Match Pictures to Categories

Now, match the pictures to the correct category:

#### 🌞 Renewable Energy (Pictures likely include):
- Sun → Sun
- Wind turbine → Wind
- Water dam → Hydropower
- Waves → Waves
- Tree/log → Biomass

#### ⛽ Non-renewable Energy (Pictures likely include):
- Oil barrel → Petroleum
- Coal pile → Coal
- Natural gas tank → Natural gas
- Nuclear plant → Nuclear
- Tractor/truck (possibly representing fossil fuel use) → Fossil fuels

✔ Final Answer (Classification)

| Renewable | Non-renewable |
|-----------------------|-------------------------|
| Wind | Coal |
| Sun | Natural gas |
| Hydropower | Petroleum |
| Waves | Fossil fuels |
| Biomass | Nuclear |

> 💡 Tip: If “fossil fuels” is listed as a separate item, it's best placed under non-renewable, since it’s a category of non-renewable sources.

✔ How to Fill Out the Worksheet

1. In the Renewable box, write:
- wind
- sun
- hydropower
- waves
- biomass

2. In the Non-renewable box, write:
- coal
- natural gas
- petroleum
- fossil fuels
- nuclear

Then, draw lines or write the words next to the matching pictures.

🧠 Summary

- Renewable: Can be replenished quickly (sun, wind, water, waves, biomass).
- Non-renewable: Finite and take millions of years to form (coal, oil, gas, nuclear fuel).

This classification helps us understand which energy sources are sustainable for the future.
