Windenergy Why wind can meet all our energy needs Jonna Bloeme Marjolein Groeneveld Roos van der Linde Eveline Wiegers

 Windenergy is produced by wind turbines  Wind turbines use wind to produce energy  Wind flows over the blades  The blades are connected to drive shaft  Drive shaft is connected to a electric generator  Electricity is generated and then sent through wires to households Windenergy: how it works

 Blades  Electric generator  Drive shaft Windenergy: how it works

 Windturbines used to be very expensive but now the price is decreasing  The government also helps with this, they are giving subsidies to support the use of windturbines What does it cost?

Wind Energy in the Netherlands nowadays  2000 Wind turbines  4% of the total Dutch electricity need  That means : enough energy to provide 1.2 million households annually in the Netherlands with energy.

Overview

YearTotal amount of windmills Total amount of power in MW Overview

Future goals in the Netherlands  Energy capacity must increase from 2000 MW in 2012 to 6000 MW in  New target to use 14% of wind energy in 2020

Planned new wind platforms in The Netherlands  2 new windplatform are planned in The Netherlands  These windplatforms will provide 100 MW each.  These projects are set up in Flevoland and the Noordoostpolder.

 The EU imposed this target:  By 2020, 20% of the energy generated must be sustainable  12% to 14% must be wind energy Future goals for Europe

Wind Energy worldwide nowadays:  Worldwide capacity of wind powered generator was 238 GW  = 2.5% of worldwide electricity usage.

Future goals worldwide  Annual growth in new installations: 27.6%  Expected growth in usage:  2013: 3.35%  2018: 8%

 Some people find wind mills a ‘pollution’ to the landscape> they take lots of space and are often considered as ugly  Wind mills make a noise  Every year, birds die, because they fly into to the rotor of a wind mill  The costs of placing wind mills are very high Disadvantages of windenergy

 There will be a shortage of fossil fuels in the future. This is not the case with wind energy; there is always wind  With the combustion of fossil fuels, CO2 is released. As we all know CO2 has a negative effect to the greenhouse effect.  Turning wind energy into electricity is relatively cheap and easy Benefits of wind energy

 Wind mills can be placed everywhere  Wind energy is the cheapest way of generating energy  When having our own energy supply, we are not dependent on instable political countries Benefits of wind energy
