This document summarizes alternative energy sources in Slovenia, including bioenergy, solar power, hydroelectric and geothermal energy, and wind energy. It provides details on production of biofuels and biomass in Slovenia, noting that over 10,900 square kilometers of Slovenia is forested. It also outlines solar power production in Slovenia, including over 3,000 operational solar power plants producing a total of 3.6 megawatts, primarily in the Primorska and Štajerska regions. The document further describes hydroelectric plants in Slovenia, including the largest producer, the Maribor plant, which generates 25.5% of Slovenia's electricity. Finally, it discusses Slovenia's emerging wind energy production, including the

Tom Maierle, 2.E

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. WOOD BIOMASS IN SLOVENIA
• 10.900 km² of forests in Slovenia (60%)
• More than 100,000 buildings

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. BIOETHANOL
• An alcohol from organic materials.
• No transport on bioethanol in Slovenia.

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. 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. COGENERATION OF HEAT AND
ELECTRICITY
• Production of heat and electricity at the same time .
• New technology already commercially interesting

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. SOLAR POWER

12. WHAT IS SOLAR POWER?
• Inexhaustible and renewable source of energy,
• Electromagnetic waves,
• Part of the natural energy flows.

13. SOLAR POWER PLANTS IN SLOVENIA
• 3215 operating solar power plants,
• The best conditions are in the Primorska region.

14. SOLAR POWER PLANTS IN SLOVENIA
• Total output of 3,6 MW,
• The strongest area represented in the Štajerska
region.

15. SOLAR PANELS
• Utilization of solar energy,
• Heating buildings and water,
• Fragility

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. USE OF SOLAR ENERGY
• Passive - solar system

18. USE OF SOLAR ENERGY
• Active - solar panels

19. USE OF SOLAR ENERGY
• With photovoltaics - solar cells

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. SOLAR ENERGY IN SLOVENIA
• Pipistrel – plane on hydrogen power cells

22. HYDRO & GEOTHERMAL
ENERGY

24. HYDROELECTRIC ENERGY
GEOTHERMAL ENERGY

25. 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.

26. DRY STEAM PLANTS
• Simplest & oldest design,
• Geothermal steam of 150°C or greater to turn
turbines.

27. FLASH STEAM PLANTS
• Flashed steam used to drive turbines,
• Requirement of fluid temperatures of at least 180°C,
• Most common type of plants.

28. BINARY CYCLE POWER PLANTS
• Most recent development,
• Acceptance of fluid temperatures as low as 57°C.
