Slide 1 - Slide

Today
.. You learn about conventional and non-conventional fossil fuels with the example of fracking & tarsands
.. You understand that non-conventional does not mean sustainable


Slide 2 - Slide

Traditional Energy Sources
Terms  you should be able to explain after this lesson:
  • fossil fuels
  • non-renewable sources
  • conventional oil and gas
  • shale gas
  • fracking
  • tar sand
  • source rock / reservoir rock (2.5)

Slide 3 - Slide

Why aren't fossil fuels sustainable?

Slide 4 - Open question

Traditionel resources
Fossil fuels -->  exhaustible energy sources 

Conventional oil and gas

'Easy' to extract
Conventional -> "usual"
"normal"

Slide 5 - Slide

Slide 6 - Video

What is the difference between conventional gas extraction and fracking for shale gas?

Slide 7 - Open question

Slide 8 - Slide

Shalegas, is not stuck in porous rock like sandstone (reservoir rock) by an impermeable layer like rock salt, but is trapped between layers of shale/slate                                                     (source rock)
Water, sand and chemicals break this rock and keep the new cracks open so gas can travel out

Slide 9 - Slide

Conventioneel vs. Onconventioneel
Conventioneel: Voorraad van een fossiele energiebron die aantoonbaar of vermoedelijk kan worden gewonnen met de tot nu toe gebruikelijke methoden en kosten.
Onconventioneel: Voorraad van een fossiele brandstof (teerzand, leisteenolie, schaliegas) die afwijkt van:
vorm - zekerheid - economische & technische winbaarheid
kost buitengewoon veel moeite, geld én energie om te winnen.
+ komt veel koolstofdioxide vrij bij het proces
+ veel overige vervuiling en aantasting van natuurlandschappen.

Tarsands
Sedimented sand and clay that contain bitumen, an oil like substance

  • Difficult to extract, expensive process
  • Environmentally unfriendly

Slide 12 - Slide

Tarsand excavation

Slide 13 - Slide

Slide 14 - Slide

01:18
Which two changes lead to the growth of the area where tarsands are mined?
A
More tarsands were discovered
B
the world market price for oil rose
C
new technology was developed
D
there was a political interest to earn more money

Slide 15 - Quiz

02:02
What's true about the size of the tarsand fields?
A
half of the Dutch provinces would fit in this area
B
The Netherlands would fit about 21x times into it
C
The Netherlands would fit 3.5x in this region
D
It's about the size of the province of Groningen

Slide 16 - Quiz

06:00
Which drawbacks could be experienced about by humans when tarsands are extracted?
(have you seen the film Erin Brokovich?)

Slide 17 - Open question

07:07
Name a benefit and drawback of mining tarsands

Slide 18 - Open question

conventional reserves
another 50 years? 100 years?
non-conventional reserves
more difficulty,  time & energy
