‘We willen dat onze studenten samenwerken met Duitse studenten van BBS uit Cloppenburg. In deze internationale Challenge krijgen ze de kans om samen te werken aan duurzame oplossingen voor een bedrijf’, vertelt Franzis Wiese, docent van ROC Friese Poort. In gemixte groepen gaan ze aan de slag met een levensechte opdracht voor Miedema Lighting, vult Roeland Westra, projectleider van Centrum Duurzaam aan. De Challenge is een initiatief van Centrum Duurzaam in samenwerking met Frysklab.

Afsluitdijk

2. Kornwerderzand

3. Polder

4. Sustainable integrated energy-systeem
Energy source
●
Wind-energy
●
Solar-energy
●
Waterpower-energy
Challenges
●
Fishpass
●
Birdfriendly
●
Supplies energy to pump the
Frisian Polder

5. Wind-energy
●
Energy gained by movement-
energy of air(wind) converted
in a usable form, for example
in elektricity
●
Windmills
Advantage
●
Low carbon energy. No
emission of greenhousegasses
●
Free energy
●
Saving of fossil fuel
●
7% of energy consumption. 2,5
million households
Disadvantage
●
Nuisance (shadow of the
wicks, view, flicker)
●
Birds (collision, brood)
●
Investment
●
Difficult permit

6. Windenergy

7. Solar-energy
●
Energy in the form of light and
warmth
●
Source of energy
●
Solarpanels met photovoltaic
cells
Advantace
●
Green energy. No emmision of
greenhousegasses
●
The sun is free energy
●
Saving of fossiele fuels
Disadvantage
●
Appearance
●
Glare
●
Investment

8. Irradiation angle

9. Hydroelectric energy
●
Energy coming from a
difference of altitude or
floadingspeed in water
Hydraulische turbine
●
Francisturbine. Height of fall.
Flow rate.
●
Kaplanturbine. Small height
of fall, hight flow rate
●
Peltonturbine. Low flow rate.
Large height of fall.
Advantage
●
Green energy. No emmision of
greenhousegasses
●
Free energy
●
Saving of fossiele fuels
●
Lots of water in the
Netherlands
Disadvantage
●
Blokkade for animals
●
Investment
●
Small height of fall
●
Max. 5% of total energy-
consumption possible

10. Hydro electric powerstation

11. Fishpassage
●
Gives fish the possibility to
take a barrier
●
Most cases a dike or a dam
●
The Netherlands are a delta-
area and has a large diversity
of fish species that life in a
delta or want to migrate
through the area.
●
Migrationfish (Eel)
●
Brackishwaterfish (plaice fish)
Advantage
●
Positive for the stock of fish
diversity of species
Disadvantage
●
Costly
●
Complicated

12. Fishpassage

13. Challenges
●
Solarpanels. Which type and how to secure them. How to capture
the most sunlight (angle of incidence, follows movement of sun)?
●
Cablework in a salty environnement?
●
Cleaning of the parts of the installation
●
How can you make the mill friendly for birds?
●
How to limit nuisance?
●
Hydroelectric powerstation. Which turbine. How does the
construction look like
●
Fishpassage. In which manner the fish can take the obstacle?
