Verified step by step guidance1
Identify the definition of renewable energy sources: Renewable energy sources are those that can be replenished naturally over short periods of time and are sustainable in the long term.
List the given energy sources: Hydroelectric energy, Wind energy, Coal, and Solar energy.
Evaluate each energy source: Hydroelectric energy is renewable as it uses water cycles. Wind energy is renewable as it uses wind, which is naturally replenished. Solar energy is renewable as it uses sunlight, which is abundant and sustainable.
Consider coal: Coal is a fossil fuel that takes millions of years to form and is not replenished on a human timescale, making it a non-renewable energy source.
Conclude that coal is the energy source that does not fit the definition of renewable energy, as it cannot be replenished naturally in a short period of time.
