  1. Wind Energy

  2. Different ways to use wind power • Theoretical possibilities • Who uses wind power? • A few pros Introduction

  3. 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 How is wind power generated?

  4. Is wind energy efficient enough? • How much can be generated then? • Powering houses • Cost efficiency Wind energy efficiency

  5. Wind as a renewable energy source in Holland • Wind farms in Holland • Offshore wind farms Wind energy in Holland

  6. Wind energy in Europe • Largest wind farms in the world Wind energy in other countries

  7. Health issues • Animals could be affected • Wind directions Are more windmills possible?

  8. Different forms and sizes • Very pricy Can we make a difference ourselves?

  9. 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. • Renewableunlimited. Comes from nuclear fusion on the sunwhen 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 pros

  10. 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 A few cons
