To determine which of the listed energy resources is renewable, it’s essential to understand the definitions of renewable and non-renewable resources.

1. Identifying Renewable Resources: Renewable energy resources are those that can be replenished naturally over short periods of time. Common examples include solar energy, wind energy, and hydroelectric power.

2. Evaluating Each Option:

   • Coal: Non-renewable resource formed from ancient organic materials; it takes millions of years to form.
   • Hydroelectric Power: Renewable resource that relies on the water cycle; water is constantly renewed through precipitation.
   • Natural Gas: Non-renewable fossil fuel, formed over millions of years, similar to coal.
   • Petroleum: Non-renewable resource; like coal and natural gas, it takes vast geological time to form.

Final Answer

Hydroelectric power is the only renewable energy resource among the options provided.
