Onderdelen in deze les



Slide 1 - Tekstslide

.. 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 - Tekstslide

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 - Tekstslide

Why aren't fossil fuels sustainable?

Slide 4 - Open vraag

Traditionel resources
Fossil fuels -->  exhaustible energy sources 

Conventional oil and gas

'Easy' to extract
Conventional -> "usual"

Slide 5 - Tekstslide

Slide 6 - Video

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

Slide 7 - Open vraag

Slide 8 - Tekstslide

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 - Tekstslide

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. 

Slide 10 - Tekstslide


Slide 11 - Video

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

  • Difficult to extract, expensive process
  • Environmentally unfriendly

Slide 12 - Tekstslide

Tarsand excavation

Slide 13 - Tekstslide

Slide 14 - Tekstslide

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

Slide 15 - Quizvraag

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

Slide 16 - Quizvraag

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

Slide 17 - Open vraag

Name a benefit and drawback of mining tarsands

Slide 18 - Open vraag

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

Slide 19 - Tekstslide

Let's make 3.2
3.1 exercises were 1-6
Check your answers of 3.1 with the online method & reflect or check your paper work with the answersheet in Teams

Use 3.2
Make 3.2 1, 3, 4, 5
