Renewable energy sources in Estonia

Made by Kerli kelder,Jaana Jürimaa,Kaija Ilves

Wind Power

• The wind energy could cover 10% of energy need in Estonia

• The avarage windspeed is 4 to 5 m/s• Good locations for producing wind energy: Vormsi

& Pakri, Naissaar, Ruhnu & Sõru, Vilsandi & Osmussaar

• Excisting windmills: Tahkuna (1997), Virtsu wind park (2002), Sõrve (2002)

• Potential windmills in the future: Pärnu, Paldiski & Türisalu cliff

Water Energy

• The hydroenergetic potential of Estonian rivers is only 1-2 %

• It would be possible to restore about 200 watermills

• Water energy was again taken into use in 1991• Restored hydropower stations: Saesaare (1991),

Leevaku (1993), Kotka, Kamari, Räpina, Tudulinna etc

• There is a hydropower station on Narva water reservoir but it’s energy goes to Russia

Leevaku Hydropower Station

• It was built by young people from Võru county• The engineer was Alfred Hanson (graduated Oxford University)• It was put into operation on 5th November 1947

Leevaku Hydropower Station

• Was turned over to the firm “Generaator” and they have restored it

• On 17th Nowember 1993 it was officially opened

• It was founded on the River Võhandu

• Max. capacity is 100kW

Leevaku Hydropower Station

• “Hurtful Light” – a rock opera for its builders

• “The Brigade of Järvesuu Boys” – a poem by Juhan Smuul, in honour of Leivaku HPS

• Was turned into a museum on 27th November, 1973

Water-mills

• On larger rivers or more steep parts of rivers (South of Estonia)

• First mentioned in the 13th century

• 758 water-mills in 1939

• Many mills destroyed in the II World War

Why to restore?

• For getting electric energy

(sustainable development!)

• To be used for making flour or sawdust

• As a turist-attraction

Biogas

• Estonian biogas is made from dung and waste mud

• Is made at Pääsküla dump, in piggeries and poultry-farms

Energy Bush

• Grows at Kambja, Võhnja, Kihlvere

• Species of trees: willow, alder, asp

State Politics

• Oil-shale will end soon – using renewable energy is favoured

• The ‘Green Energy’ project
