Wind Energy
Introduction
*Different ways to use wind power
*Theoretical possibilities
*Who uses wind power?
*A few pros
How is wind power generated?
*Wind
*Gas particles move quickly
*Motion = kinetic energy
*Wind-electric turbine
*Blades capture kinetic energy
*Move
*Spin shaft between hub and generator
*Generator turns rotational energy into electricity
Wind energy efficiency
*Is wind energy efficient enough?
*How much can be generated then?
*Powering houses
*Cost efficiency
Wind energy in Holland
*Wind as a renewable energy source in Holland
*Wind farms in Holland
*Offshore wind farms
Wind energy in other countries
*Wind energy in Europe
*Largest wind farms in the world
Are more windmills possible?
*Health issues
*Animals could be affected
*Wind directions
Can we make a difference ourselves?
*Different forms and sizes
*Very pricy
A few pros
* No pollution/radioactive waste. Construction + installation has less environmental impact.
* No need for supplies like fuel. When power lines break, wind power won’t lose supply of electricity.
* Can generate power for a large amount of households
* No use of non-renewable resources like coal, gas or oil. Won’t contribute to eventual thinning of these resources or environmental harm by using these.
* Renewableunlimited. Comes from nuclear fusion on the sunwhen sun keeps shining, we have wind energy on earth. Fossil fuels run out.
* Can be done on most places (some more preferable than others)
* Prices are decreasing and have decreased
* People can produce it themselves at home, and companies can do this too and some even sell it
* Works together easily with other renewable energy methods like solar panels and geothermal heating
A few cons
* Some people have the opinion that wind turbines are destroying the view because they are so tall and noticeable
*Wind turbines can be damaged in thunderstorms (lightning), because of their tall shape, and when they need to be repaired it costs a lot of money
*Birds can be killed when they fly between the blades of a wind turbine
*Wind turbines can make noise, especially when there isn’t much wind
*Wind is unpredictable, so wind energy is not reliable enough for a base load of energy. Therefore, wind energy must always be used together with other energy supplies
* The projects to set up wind farm cost very much money, is this worth it and does it pay back?
*Wind turbines do not (always) suit in the view/environment
