Educational worksheet for students to classify energy sources as renewable or non-renewable.

Let’s go through each picture one by one and figure out what energy source it shows, then decide if it’s renewable or non-renewable.

1. Windmill
→ This uses wind to make electricity.
→ Wind never runs out — it’s always blowing somewhere.
→ So, this is renewable.

2. Fireplace with logs burning
→ This burns wood (trees).
→ Trees can be replanted, but it takes years to grow them back.
→ However, in most school contexts, wood is considered renewable because we can grow more trees.
→ *Note: Some might argue it’s not perfectly renewable if forests are cut down too fast, but for this level, we’ll say renewable.*

3. Electrical plug / outlet
→ This doesn’t show the source — it just shows electricity being used.
→ But since the question asks “What is the energy source?”, we need to think: where does plug-in electricity usually come from?
→ In many places, it comes from coal, gas, or nuclear — which are non-renewable.
→ BUT — sometimes it comes from solar, wind, or hydro — which are renewable.
→ Since the image doesn’t specify, and it’s a generic plug, we should consider the most common global sources: mostly non-renewable.
→ However, looking at typical worksheets like this, they often expect you to recognize that “electricity from the wall” is usually from non-renewable sources unless specified otherwise.
→ Let’s go with non-renewable for now — but note: this one is tricky!

Wait — let’s double-check. Actually, in many elementary science sheets, when they show a plug without any other clue, they may intend for students to realize that electricity itself isn’t a source — it’s an energy carrier. But since the worksheet forces us to pick, and given the context of the other images, perhaps this is meant to represent fossil fuel-based power plants. We’ll stick with non-renewable.

4. House with solar panels on roof
→ Solar panels use sunlight.
→ Sunlight will keep shining for billions of years.
→ Definitely renewable.

5. Water wheel next to flowing water
→ This uses moving water (like a river) to turn the wheel and make energy.
→ Water cycles through nature — rain fills rivers again and again.
→ So, this is renewable (hydroelectric power).

6. Oil rig drilling into ground + oil tanker truck
→ This is clearly extracting oil from underground.
→ Oil takes millions of years to form — once we use it, it’s gone.
→ Very definitely non-renewable.

Now let’s list them all clearly:

- Windmill → Wind → Renewable
- Fireplace → Wood → Renewable (for school purposes)
- Electrical plug → Usually from fossil fuels → Non-renewable
- House with solar panels → Sun → Renewable
- Water wheel → Flowing water → Renewable
- Oil rig & truck → Oil → Non-renewable

Final Answer:
Source: Wind | Renewable or Non-renewable: Renewable
Source: Wood (biomass) | Renewable or Non-renewable: Renewable
Source: Electricity (from grid, typically fossil fuels) | Renewable or Non-renewable: Non-renewable
Source: Solar energy | Renewable or Non-renewable: Renewable
Source: Hydropower (flowing water) | Renewable or Non-renewable: Renewable
Source: Oil (fossil fuel) | Renewable or Non-renewable: Non-renewable
