| Crude Oil |
Extracted from oil wells through drilling |
Transportation, fuel for power generation, industrial uses |
High energy density, easy to transport |
Air pollution, carbon emissions, oil spills |
Carbon monoxide, nitrogen oxides, sulfur dioxide |
| Natural Gas |
Extracted from gas wells through drilling or extracted alongside crude oil |
Power generation, heating, cooking, industrial uses |
Cleanest burning fossil fuel, high energy efficiency |
Methane emissions, can leak during production and transportation |
Carbon dioxide, nitrogen oxides |
| Liquefied Petroleum Gas (LPG) |
Extracted during crude oil refining or extracted alongside natural gas |
Cooking, heating, transportation |
Clean burning, easy to store and transport |
Non-renewable, carbon emissions during production and transportation |
Carbon monoxide, nitrogen oxides |
| Compressed Natural Gas (CNG) |
Extracted alongside crude oil or natural gas |
Transportation, cooking |
Lower emissions than petrol and diesel, cost-effective |
Requires specialized vehicles and refueling stations, less energy-dense than petrol and diesel |
Carbon monoxide, nitrogen oxides |
| Shale Gas |
Extracted through hydraulic fracturing of shale rock formations |
Power generation, heating, cooking, industrial uses |
Abundant, reduces dependence on foreign oil, lower carbon emissions than coal |
Requires large amounts of water, potential for groundwater contamination, methane leaks |
Carbon dioxide, nitrogen oxides |
