Energy Resources

Learning objectives To learn how fossil fuels were formed and

how they are obtained To consider how long they may last.

Carbon based energy forms These have provided the majority of the

worlds energy since the early industrial revolution.

They are:

Where is the coal?

Coal resources are located by geologists. It is thought that most of the world’s resources have already been located, but the continent of Antarctica remains unexploited.

How is coal mined? Originally harvested by hand this picture

from NE England (Billy Elliot territory) shows the practice still taking place in 1939.

Early pit mines A medieval bell pit from Scotland (originally started in the 1200s)

What you would see today in the hills near Manchester

Mine Shafts (adits) As this 16th century German drawing

shows mines became more complex

Today

Modern Mechanised USA More typical and traditional Pakistan

Open Cast coal mines Much more high tech, much more impact

on surface environment, much more economical.

World reserves and usage Fossil fuels will remain the primary sources

of energy, meeting more than 90% of the increase in demand.  Global oil demand will rise by about 1.7% per year, from 75mb/d in 2000 to 120mb/d in 2030. 

World reserves (recent estimate) 1077498 million barrels

= about 25 ½ years supply at predicted 2030 usage

Where the oil is

Known resources (mid 2000s)

Other factors to consider 1. More may be found (Antarctica!) 2. Usage may grow more or less than

predicted 3. Value will increase making currently

uneconomic reserves workable 4. Cost may increase reducing

consumption. 5. Global warming may become

catastrophic and fossil fuel use may have to stop.

Los Heroes

Homework Oil formation (in teams) Draw a poster to show the process of oil formation

and its extraction. Include 1. the stages of its production 2. information explaining how the oil is formed 3. Information showing time scale 4. Include it against a background of world oil

producing areas. 5. Include images showing its extraction explaining

what is being shown. (5 marks per section)
