Identify Renewable Energy Resource

Renewable energy resources can be replenished naturally over a short period, while non-renewable resources exist in finite quantities and are consumed much faster than they form.

Resource Analysis

• Coal: A fossil fuel formed over millions of years. Non-renewable.
• Petroleum: Also known as crude oil, a fossil fuel formed over millions of years. Non-renewable.
• Natural gas: A fossil fuel formed alongside petroleum and coal. Non-renewable.
• Syngas: A fuel gas mixture (primarily hydrogen and carbon monoxide). It can be produced through processes like coal gasification (non-renewable) or biomass gasification (renewable). Since it *can* be derived from renewable sources like biomass, it is considered a potential renewable energy resource in this context, distinguishing it from the strictly non-renewable fossil fuels listed.

Conclusion

Based on the analysis, Syngas is the correct choice as it can be produced from renewable biomass sources, unlike coal, petroleum, and natural gas, which are finite fossil fuels.
