Renewable energy is energy produced from sourece that do not deplete or can be replenished within a human's life time. The most common examples include wind, solar, geothermal, biomass, and hydroelectric power. This is in contrast to non-renewable sources such as fossil fuels. Most renewable energy is derived direcetly or indirectly from the sun. Sunlight can be captured directly using solar technologies. The sun's heat drives winds, whose energy is captured with turbines. Plants also rely on the sun to grow and their stored energy can be utilized for boienergy. Not all renewable energy sources rely on the sun. For example, geothermal energy utilizes the Earth's internal heat, tidal energy relies on the gravitational pull of the moon, and hydroelctric power relies on the flow of water.
Name the renewable sources of energy which are not dependent on sun. What are they dependdent upon?

Explanation

To answer the question regarding renewable energy sources that are not dependent on the sun, we will follow these steps:

### Step-by-Step Solution:

1. **Identify Renewable Energy Sources**: We need to list the renewable energy sources that do not rely on sunlight for their energy production.

2. **Analyze Each Source**:
- **Geothermal Energy**: This energy comes from the heat stored in the Earth's core. It is not dependent on the sun but rather on the internal heat of the Earth.
