Evaluate the costs and benefits (more than economic) of using coal, oil, and natural gas. In your evaluation, provide the pros and cons and the context in which each energy source would work best.
What will be an ideal response?
| Fossil Fuel | Pro | Con | Best context to be used |
| Coal | - most abundant - newer technology less polluting | - most polluting fossil fuel - many negative environmental impacts (mining, transporting, burning) | - remove sulfur or use IGCC method |
| Oil | - cleaner than coal - many possible unconventional sources - exploration and drilling techniques improving | - drilling and transporting pollutes the oceans - limited supply - burning emits CO2 | - use locally to reduce costs and environmental damage when transporting (if available) |
| Natural gas | - cleanest burning fossil fuel - easy and economical to ship through buried pipelines | - least abundant; probably less than a 50-year supply remaining - dangerous to ship and store between continents | - use locally (if available) |
