Four-leave Clover
Installation with integrated energysysteem
● Saves Fossil fuel● Saves space by combining:
● Wind-energy● Solar-energy● Hydro-energy● Delivering energy for the
Frisian polder wateringpumps
● Location Kornwerderzand. Afsluitdijk
Kornwerderzand
Polder
Sustainable integrated energy-systeem
Energy source● Wind-energy● Solar-energy● Waterpower-energy
Challenges● Fishpass● Birdfriendly● Supplies energy to pump the
Frisian Polder
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
Windenergy
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
Irradiation angle
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
Hydro electric powerstation
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
Fishpassage
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?
