natural gas Flashcards
1
Q
occurence and extraction
A
- formed from decaying animal and plant matter that lived millions of years ago
- found underground, trapped in deep shale formations
- wells are drilled and due to the pressure of the pumped water the gas comes up to the surface and is pumped through pipelines
- refined to removes unwanted chemical impurities and then shipped in tankers
- Russia, Iran and Qatar have the largest reserves of natural gas
2
Q
uses
A
- industrial
- electric generation
- residential
-commercial
3
Q
advantages
A
- cleaner fuel producing fewer carbon emissions than coal or oil
- does not produce waste and disperses quickly in case of leaks
- allows quick results and precise control
- more abundant than other fossil fuels
- easy to distribute and transport
4
Q
disadvantages
A
- produces greenhouse gas emissions that contribute to enhanced greenhouse effect
- finite resources - cannot become reliant on it
- if inhales, the gas is toxic and colorless so cannot be easily detected
- storing gas is more expensive due to larger volume
- pumping of gas and fracking increases tectonic activity
5
Q
peru
A
- Camasea project was launched in 2004 to extract natural gas in the Amazon
- predicted to save Peru $4 billion in energy costs
- this came at the expense of the lives of indigenous tribes who lived in the area
- deforestation took place to create infrastructure such as pipelines for the extraction process
- offered within the $34 billion it was expected to offer over a 30 year lifespan in exports
