Slovenian presentation in Hungary

  1. 1. Alternative Energy Sources Slovenia Viribus Unitis - help the world with joint efforts 4th meeting, Baktay Ervin Gimnázium , Dunaharaszti, Hungary, 4 - 11 October, 2013 www.viribusunitis.org www.viribusunitis.blogspot.com
  2. 2. BIOENERGY Tilen Resnik, 3.G Tom Maierle, 2.E
  3. 3. WHAT IS BIOENERGY? • A renewable energy made from biological sources. • We divide bioenergy into: - “Biowarm” or thermal energy, - “Bioelectricity” or electricity from biomass, - Biofuels (solids, liquids and gases).
  4. 4. WOOD BIOMASS IN SLOVENIA • 10.900 km² of forests in Slovenia (60%) • More than 100,000 buildings
  5. 5. BIODIESEL • Produced from left-over food products, • Biodiesel consumption in Slovenia: - 2008: at least 2%, - 2009: at least 3,0 %, - 2010: at least 3,5 %, - 2011: at least 4 %, In the 5 years after the year 2011: at least 5% of energy.
  6. 6. BIOETHANOL • An alcohol from organic materials. • No transport on bioethanol in Slovenia.
  7. 7. CHARCOAL • New way of direct processing. • Used for cooking and heating, producing synthetic gas, etc. • We have charcoal producton in Pohorje and Koroška.
  8. 8. METHANE • Methane is a chemical compound with the chemical formula CH 4. • Vehicles on methane gas are more eco. • We have buses on methane gas. • 2010: first car in Slovenia
  9. 9. COGENERATION OF HEAT AND ELECTRICITY • Production of heat and electricity at the same time . • New technology already commercially interesting
  10. 10. THE PRODUCTION OF HEAT • Local heating: wood, pellets, wood chips, etc. • District heating: wood chips, peat, fuel from waste wood, sawdust, and straw.
  11. 11. SOLAR POWER Patricija Arh 2.C Maja Štojs 2.C Monika Novak 3.D
  12. 12. WHAT IS SOLAR POWER? • Inexhaustible and renewable source of energy, • Electromagnetic waves, • Part of the natural energy flows.
  13. 13. SOLAR POWER PLANTS IN SLOVENIA • 3215 operating solar power plants, • The best conditions are in the Primorska region.
  14. 14. SOLAR POWER PLANTS IN SLOVENIA • Total output of 3,6 MW, • The strongest area represented in the Štajerska region.
  15. 15. SOLAR PANELS • Utilization of solar energy, • Heating buildings and water, • Fragility
  16. 16. KEY BENEFITS OF THE USE OF SOLAR ENERGY • • • • Inexhaustible source of energy, Low maintenance costs, Lower consumption of fossil fuels, Reduction of CO2 emissions.
  17. 17. USE OF SOLAR ENERGY • Passive - solar system
  18. 18. USE OF SOLAR ENERGY • Active - solar panels
  19. 19. USE OF SOLAR ENERGY • With photovoltaics - solar cells
  20. 20. SOLAR ENERGY IN SLOVENIA • Substantial and far-reaching advance, • 400 new solar plants in 2010, • The primary promoter is the Slovenian photovoltaic industry association.
  21. 21. SOLAR ENERGY IN SLOVENIA • Pipistrel – plane on hydrogen power cells
  22. 22. HYDRO & GEOTHERMAL ENERGY Matej Kokalj, 3. F Jan Dežman, 4. C
  23. 23. HYDROELECTRIC ENERGY GEOTHERMAL ENERGY
  24. 24. GEOTHERMAL ENERGY • Heat from the Earth, • Clean and sustainable, • Technologies taking advantage of geothermal energy. • • • • Energy plants: dry steam power plants, flash steam power plants, and binary cycle power plants.
  25. 25. DRY STEAM PLANTS • Simplest & oldest design, • Geothermal steam of 150°C or greater to turn turbines.
  26. 26. FLASH STEAM PLANTS • Flashed steam used to drive turbines, • Requirement of fluid temperatures of at least 180°C, • Most common type of plants.
  27. 27. BINARY CYCLE POWER PLANTS • Most recent development, • Acceptance of fluid temperatures as low as 57°C.
  28. 28. GEOTHERMAL ELECTRICITY
  29. 29. GEOTHERMAL ELECTRICITY
  30. 30. BENEFITS • Emissions contain few chemical pollutants and little waste, • Geothermal electricity sold to local power grids, • Clean energy for some of the world‟s most rapidly expanding economies.
  31. 31. HYDROELECTRIC ENERGY • Energy from hydropower or water power, • Usage of the Earth's water cycle to generate electricity, • High precipitation levels and large elevation changes necessary to generate significant quantities of electricity.
  32. 32. ALTERNATIVE ENERGY PLANTS IN SLOVENIA • Hydroelectric plants such as Blanca, Boštjan, Maribor, Medvode, Moste, and Vrhovo.
  33. 33. HYDROELECTRIC PLANT MARIBOR • Largest Slovenian producer of electric power using renewable resources, • Generating 25,5 % of electric power in Slovenia, • 80 % of Slovenia‟s electric power using renewable energy sources, • Electric power generated in an environmentally friendly manner.
  34. 34. HYDROELECTRIC ENERGY ADVANTAGES • Electricity can be constantly produced, once a dam is constructed, • Dams designed to last decades, • Not producing any green house gases.
  35. 35. HYDROELECTRIC ENERGY DISADVANTAGES • Dams extremely expensive to build, • Dams must be built to a very high standard, • People forcibly removed so that hydro-power schemes can go ahead.
  36. 36. SOLVING PROBLEMS • Limit the use of fossil fuels, • Expand the usage of alternative fuels, • Slowing down the degradation of the destruction of our atmosphere.
  37. 37. ENVIROMENTAL ISSUES IN SLOVENIA • Greenhouse emissions caused by traffic in decline since 2008, • Biggest state investments focused on state roads, • Biofuels accounting for 2% in Slovenia, • Air quality problematic, as the biggest problems being nitrogen oxides and dust particles.
  38. 38. WIND ENERGY Jaka Zorman, 3.f Špela Pozvek, 3.c
  39. 39. HISTORY
  40. 40. JAMES BLYTH • First attempt, • 1887, • For the production of hydrogen.
  41. 41. MODERN WIND TURBINES • Kuriant, Nordtank, and Bonus, • 20 – 30 KW
  42. 42. TODAY
  43. 43. TODAY WIND TURBINES • Enercon E-126 – 8 MW • Other – 3 MW
  44. 44. TYPES
  45. 45. WIND FARMS • Alta Wind Energy Center (USA), • 1,320 MW
  46. 46. HOW IT WORKS
  47. 47. ADVANTAGES • • • • Clean energy, Does not destroy the working surfaces, Money back in 14 years, Lasts 25 years.
  48. 48. DISADVANTAGEs • Danger to birds, • Requires more conventional power plants to address variability, • Wind turbines are noisy.
  49. 49. FACTS • In 2010 all wind turbines generated 197 GW, • Today they generate 430 THW, which is 2.5% of global electrical energy consumption, • In the last five years, the annual growth of new plants was 27.6 percent.
  50. 50. FIRST BIG SLOVENIAN WIND TURBINE • • • • Dolenja vas near Senožeče, 29.9.2012, Enercon E-70, 2,3MW
  51. 51. PROBLEMS IN SLOVENIA • For cottages„ energy, • Documentation and licenses, • Natural heritage
