Flowchart illustrating the two main types of energy sources: renewable and non-renewable.

The image provided is a flowchart or mind map that categorizes Energy into two main types: Non-Renewable and Renewable. The task appears to be filling in the blanks with appropriate examples of each type of energy source.

Solution:

#### 1. Non-Renewable Energy Sources:
Non-renewable energy sources are finite resources that cannot be replenished within a human timescale. Examples include:
- Coal
- Oil (Petroleum)
- Natural Gas
- Nuclear Energy (though nuclear fuel is not renewable, it is often grouped here due to its non-renewable nature)

#### 2. Renewable Energy Sources:
Renewable energy sources are those that can be replenished naturally over time. Examples include:
- Solar Energy
- Wind Energy
- Hydroelectric Power (Water)
- Geothermal Energy
- Biomass

Filling in the Blanks:

Here is how the flowchart can be completed:

```
+-------------------+
| NON-RENEWABLE |
+-------------------+
|
v
+-----------+
| ENERGY |
+-----------+
|
v
+------------------+
| RENEWABLE |
+------------------+
|
+----------------+ +----------------+
| | | |
v v v v
+-------+ +--------+ +---------+ +----------+
| Coal | | Oil | | Natural Gas | | Nuclear |
+-------+ +--------+ +---------+ +----------+
| | | |
v v v v
+-------+ +--------+ +---------+ +----------+
| | | | | | | |
+-------+ +--------+ +---------+ +----------+
```

And for the Renewable section:

```
+------------------+
| RENEWABLE |
+------------------+
|
+----------------+ +----------------+
| | | |
v v v v
+-------+ +--------+ +---------+ +----------+
| Solar | | Wind | | Hydro | | Geothermal|
+-------+ +--------+ +---------+ +----------+
| | | |
v v v v
+-------+ +--------+ +---------+ +----------+
| | | | | | | |
+-------+ +--------+ +---------+ +----------+
```

Final Answer:

Non-Renewable:
- Coal
- Oil
- Natural Gas
- Nuclear Energy

Renewable:
- Solar Energy
- Wind Energy
- Hydroelectric Power
- Geothermal Energy
- Biomass

Thus, the completed flowchart would look like this:

```
+-------------------+
| NON-RENEWABLE |
+-------------------+
|
v
+-----------+
| ENERGY |
+-----------+
|
v
+------------------+
| RENEWABLE |
+------------------+
|
+----------------+ +----------------+
| | | |
v v v v
+-------+ +--------+ +---------+ +----------+
| Coal | | Oil | | Natural Gas | | Nuclear |
+-------+ +--------+ +---------+ +----------+
| | | |
v v v v
+-------+ +--------+ +---------+ +----------+
| | | | | | | |
+-------+ +--------+ +---------+ +----------+

+----------------+ +----------------+
| | | |
v v v v
+-------+ +--------+ +---------+ +----------+
| Solar | | Wind | | Hydro | | Geothermal|
+-------+ +--------+ +---------+ +----------+
| | | |
v v v v
+-------+ +--------+ +---------+ +----------+
| | | | | | | |
+-------+ +--------+ +---------+ +----------+
```

Final Answer:
$$
\boxed{
\text{Non-Renewable: Coal, Oil, Natural Gas, Nuclear Energy; Renewable: Solar, Wind, Hydro, Geothermal, Biomass}
}
$$
