1. Shpogy Secondary School BUILDING A WIND TURBINE Research work in English Authors: Annija Abarone Form 8 The Adviser of the Research Work: Eva Vovka Shpogy, 2014

2. To make a wind turbine from recycled materials at school. The aim: The tasks: To visit a wind farm (Liverpool, PEEL energy) and attend a lecture about wind energy; To collect theoretical information about a wind turbine; To make the wind turbine; To test it; To summarize the results of the research work and present the results. Methods: work with literary resources, observation, research, experiment, anal yses, comparison 3. Theoretical Part WHAT IS RENEWABLE ENERGY Renewable energy resources are those that never exhaust (solar, wind, geothermal, etc.). They are environmentally friendly . Wind energy is renewable and can be used in producing electricity. The use of wind power does not cause pollution and any harm to humans health. 4. The first wind power was exploited in sailing vessels used by ancient Greeks. The wind was blowing into sails and gave necessary power to move. Later people used wind power with the creation of windmills. For example, the Netherlands is famous for its windmills. During the last 25 years new generation wind generators have been created, their design is based on windmills, but for different use. Wind generators produce electric power. Theoretical Part HISTORY 5. A set of wind turbines is called wind farm Wind turbines can be: Small (20 - 3000 W)- supply with an energy individual objects Medium (30600 kW) are united in groups and make wind farms Big (more than 1 MW)- a whole city can be supplied with energy WIND TURBINE The most popular are three blade windmills. They are installed on approximately 60 m high metallic towers. Electric energy is produced by exploiting the wind when it is higher than 3 m/s allowing thus a speed rotation of the three-blade rotors higher than 14-31,4 rpm Aerogenerators transform wind energy into electric energy Then the electric energy is transformed to the net 6. Wind power (Comenius partner countries) Chart 1 7. QUESTIONAIRE The students mentioned all the renewable energy resources TOP FIVE ACTUALLY IS: 1. GERMANY 2. GREECE 3. SPAIN 4. DENMARK 5. THE UK 8. QUESTIONAIRE 9. QUESTIONAIRE 10. PRACTICAL PART OUR WIND GENERATOR SPECIAL THANKS TO MR VARCS AND MR SUVEIZDA 11. Wind turbine models made by our partners: LATVIA 12. The research work is based on Comenius activity- sustainable or renewable energy resources. During our meeting in Liverpool the participants visited PEEL energy wind farm, attended the lecture and presented videos about wind energy in their countries. Wind turbines have many benefits: produce green electric power, no waste; it is renewable and inexhaustible; as well as some drawbacks: blades can kill or injure migrating birds; it causes noise pollution; construction and maintenance is expensive. The survey carried out proves that in my school we have good awareness of sustainable energy resources. The future is in our hands, the political situation proves that we have to think more how to provide ourselves with the energy. Green energy could be the best solution. CONCLUSION
