Planning
  • Couple of questions about last week
  • Energy transition
  • Sustainable fuel sources

Slide 1 - Diapositive

Which element are trees mainly made of?
A
Carbondioxide (CO2)
B
Water (H2O)
C
Carbon (C)
D
Oxygen (O2)

Slide 2 - Quiz

What are trees (mainly) made of?
  • Plants take in carbondioxide (CO2), and 'breathe out' oxygen (O2)
  • Trees are made of carbon (C)

Slide 3 - Diapositive

What are the two biggest drawbacks of fossil fuels?

Slide 4 - Question ouverte

Energy transition
Going from fossil fuels to sustainable sources of energy
  • Those don't run out
  • Don't put extra CO2 in the atmosphere

going from grey to green energy

Slide 5 - Diapositive

Grey energy
  • Fossil fuels
  • We are still dependent on these fuels
  • (and on the countries delivering them)

Slide 6 - Diapositive

Green energy
Sustainable sources of energy
  • They don't run out
  • They don't cause emissions of greenhouse gasses

Slide 7 - Diapositive

Slide 8 - Diapositive

Slide 9 - Vidéo

Biomass energy
Burning, or decomposing bioorganic materials (plants and stuff) to make energy.

Slide 10 - Diapositive

Biomass energy
The good:
  • It makes use of waste
  • It is renewable
  • It emits no more greenhouse gasses than the plants have absorbed over their lifetime

Slide 11 - Diapositive

Biomass energy
The bad:
  • It still produces greenhouse gasses
  • It is only renewable if no trees are cut down for it

Slide 12 - Diapositive

Wind energy
Energy made from spinning turbines around using the wind

Slide 13 - Diapositive

Wind energy
The good:
  • Doesn't produce greenhouse gasses
  • It is renewable

Slide 14 - Diapositive

Wind energy
The bad:
  • They are fairly ugly
  • Wind is not always blowing
  • We are dependent on China for the magnets

Slide 15 - Diapositive

Slide 16 - Vidéo

Solar energy
Energy made from the UV-radiation of the sun

Slide 17 - Diapositive

Solar energy
The good:
  • Doesn't produce greenhouse gasses
  • It is renewable
  • You can easily put them everywhere on roofs

Slide 18 - Diapositive

Solar energy
The bad:
  • The sun is not always shining
  • We rely on China for many of the resources

Slide 19 - Diapositive

Hydro electricity
Using the power of gravity and water to make energy

Slide 20 - Diapositive

Hydro electricity
The good
  • Water is (almost) always flowing
  • No emissions
  • Can be turned on when needed

Slide 21 - Diapositive

Hydro electricity
The bad
  • Water can get too low if there is a major drought
  • It is not available to everyone

Slide 22 - Diapositive

Geothermic energy
Using heat from the inside of the earth to generate electricity

Slide 23 - Diapositive

Geothermic energy
The good
  • Never runs out
  • No emissions

Slide 24 - Diapositive

Geothermic energy
The bad
  • Not available to everyone

Slide 25 - Diapositive

Nuclear energy
Energy created by using nuclear fission

Slide 26 - Diapositive

Nuclear energy
The good
  • Extremely effcient
  • No greenhouse gasses
  • Fairly sustainable

Slide 27 - Diapositive

Nuclear energy
The bad
  • It can cause disasters
  • Nuclear waste

Slide 28 - Diapositive

Slide 29 - Vidéo

Conclusion
There are a lot of different sources of sustainable energy
But all of them have their own unique benefits, and drawbacks
Every country has to decide which is best for them
