Coal, Natural Gas, Petroleum Overview
Summary:
- Organic fuels; coal, natural gas, petroleum
- Fossil fuel; dead plant matter; carbon content 65–95%; additional elements: hydrogen, sulfur, oxygen, nitrogen
- Natural gas; hydrocarbon gas mixture; main component: methane; additional components: other alkanes, CO₂, nitrogen, H₂S, helium
- Petroleum; hydrocarbon mixture; refined by fractional distillation
- Projected depletion dates: coal (2500), natural gas (2045), petroleum (2055)
