Subquestions:-Where are the windmills located nowadays?-Why are the windmills located there?-Where will the windmills be built in the future?-Why will the windmills be built there?-What are the differences of wind energy in The Netherlands compared to Germany and Denmark?

General information

• Approximately 2000 windmills are located in The Netherlands

• The wind turbines generate as much electricity as 600.000 households are using

• Most famous mills generated by wind are the mills in Kinderdijk

• The from origin 20 mills from Schiedam are among the highest mills in the world

Where are the windmills located now and why are they located there?

• There is not a lot of space in The Netherlands for placing windmills

• Requirements for building wind turbines:- The distance between windmills- The height of a windmill

- Visual pollution• Most windmills are located in the provinces with

most wind: Groningen, Friesland, Flevoland, Zeeland and (the northern part of) Noord-Holland

• Just a few windmills are located inland

Where are the windmills located now and why are they located there?

• There are also windmills located in the sea• Benefits of windmills that are located in the sea:

- More space- More wind- No obstacle for the view of people because

nobody is living there

Where are the windmills located and why are they located there?

Windmillparks in The Netherlands

Where will the windmills be built in the future and why there?

• Replacement of old, small windmills by modern, large models

• Preferences for building large windmillparks in:- Ports and industrial areas

- Large scale agricultural landscapes- Along the cost or in large lakes or in the sea- Along roads and railways

Where will the windmills be built in the future and why there?

• Smaller initiatives are also important to reach the national purposes

• Building of windmills in the sea: Egmond aan Zee (Noord-Holland)

• If the windmills, located in the sea, will be successful, 20-30% of the energy demand in the future will be generated by wind turbines

Egmond aan Zee

Where will the windmills be built in the future and why there?

• Windmills located in the sea generate approximately 50% more energy than windmills located on the land

• Condition for building a windmill in the sea: the sea should not be deeper than 40 metres

• A project on the westcoast of Norway: floating windmills

• Disadvantage of windmills located in the sea: they are difficult to maintain

8 windmillparks of 10.000 km² in the sea, can provide the whole of Europe with electricity.

Where will the wind turbines be built in the future and why there?

Expected increase of wind energy in the period 2012-2020

What are the differences of wind energy in The Netherlands compared to Germany and Denmark?

• Germany: - Germany is a leading country based on the

introduction of wind energy- Germany has not such a long coastline

compared to The Netherlands- Germany has a hilly landscape

What are the differences of wind energy in The Netherlands compared to Germany and Denmark?

• Denmark:- Denmark has worldwide the largest

contribution to the national energy demand (24%)

- Denmark controls approximately 40% of the worldmarket of the production of energy out of wind energy

- Denmark has a favorable geographical location for generating wind energy

What is the most favorable location for placing windmills?

• The effectivity of windmills depend on:- The wind speed (faster than 5 m/s)- The presence of buildings in the surroundings- The presence of hills and trees in the

surroundings

What is the most favorable location for placing windmills?

-Looking at the effectiveness-factors, it would not be smart to place wind turbines in the south of the province of Limburg

-It would be more logical to place windmills in the sea or in the north of the province of Noord-Holland.

-Dikes can also be a favorable location to place windmills
