- What is natural gas?
- It is a hydrocarbon
- Formed from the decomposition of living organisms
- Found in sedimentary rocks
- Shale gas is a type of natural gas extracted by fracking
- Natural Gas
- Extracting natural gas
- Advantages
- Cleanest of the fossil fuels
- 45% less CO2 than other fossil fuels
- Less toxic chemicals like NO and SO2
- Less risk of environmental accidents like oil spills
- Provides employment for 1.2 million people
- Can be transported in a variety of ways
- Pipeline
- Tankers
- Road tankers
- Relatively abundant supply compared to other fossil fuels
- Shale gas has increased supply
- Power stations can be turned off and on - no waste
- Cleanest of the fossil fuels
- Disadvantages
- Dangerous if handled or transported carelessly
- Some supplies in politically unstable countries
- Can be used as a weapon
- Pipelines can be terrorist targets
- Contributes to global warming - CO2 and methane
- Fracking is controversial
- Pipelines are expensive to build and maintain
- Advantages
- Fracking
- Advantages
- Gas is cheaper
- Produces less CO2 than coal fired power stations
- Less reliance on foreign countries for energy
- Increase use of fracking technology lead to 67% increase in employment
- Using fracking gives us time to develop alternatives
- Disadvantages
- Harmful water pumped back into the ground water
- Ecosystems harmed by poisonous chemicals
- Harmful toxins like methane released
- 72 trillion gallons of water used in fracking in the USA
- 40,000 gallons of chemicals used per fracture
- Advantages
- Extracting gas in the Amazon
- Advantages
- Could save Peru $4 billion in energy costs
- Peru could make $billions by exporting gas
- Provides employment opportunities and helps boost local economy
- Improved infrastructure brings benefits to local people
- Disadvantages
- Deforestation associated with the pipeline will affect habitats
- Impact on the indigenous tribes in the local area
- Local people have no immunity to diseases brought in by developers
- Clearing space for pipeline has led to landslides and water pollution
- Reduction in fish stocks
- Advantages
- Extracting natural gas
