The Process of Creating Natural Gas

• The process is the same as the process to create
  oil, with one important difference.
•   

4
The Process of Creating Natural Gas

• Instead of being buried between 7500 and 15000
  feet, the natural gas is buried at greater
  depths.
•   

5
Location of Worlds Natural Gas

• Natural gas is more widely distributed than oil.
• In almost all oil fields, there are natural gas
  fields.
• In addition, there are many fields in areas
  without oil.

Advantages of Using Natural Gas
7
The Advantages of Natural Gas

• 1) Natural Gas (NG) is still cheap.
•   

8
The Advantages of Natural Gas

• 2) There is an abundance of NG globally, at least
  a centurys worth at current use.
•   

9
The Advantages of Natural Gas

• 3) There is an still plenty of NG in the North
  America, although not that much in the US.

Disadvantages of Using Natural Gas
11
The Disadvantages of Natural Gas

• 1) Like petroleum, burning natural gas generates
  a lot of air pollution.
•   

12
The Disadvantages of Natural Gas

• 2) Burning natural gas worsens global warming.
•   

13
The Disadvantages of Natural Gas

• 3) The pumping and transportation of natural gas
  generates a lot of methane.
• Methane is about 17 worse than carbon dioxide
  for the problem of global warming.

14
The Disadvantages of Natural Gas

• 4) To expand the production of NG, we will need
  to spend hundreds of billions to liquefy NG and
  transport it in liquid form.
•   

15
The Disadvantages of Natural Gas

• 5) Liquid Natural Gas (LNG) is very hazardous to
  transport and store.  
• A ship the size of the Exxon Valdez would explode
  with the power of a small nuclear bomb.

16
The Disadvantages of Natural Gas

• 6) The US will need to drastically increase its
  imports of NG if it wants to substitute NG for
  coal or petroleum.
• Where do we put the refineries and pipelines?
