Energeetiline iseseisvus on oluline komponent riigi iseseisvuses ning julgeolekus. Siiani
on selle Eestis taganud põlevkivi, kuid oma kahjuliku mõju tõttu keskkonnale tõrjub seda
aina enam välja taastuvenergia. Sellest tulenevalt on käesoleva bakalaureuse töö eesmärk
anda ülevaade Eesti taastuvenergia olukorrast ning tuleviku plaanidest. Töös kasutatakse
erinevate andmebaaside ning aastaraamatute andmeid, et luua ülevaade, kuidas on
taastuvenergia osakaal ajas muutunud. Lisaks näidatakse erinevate energiaallikate lõikes,
milline on nende areng ajas olnud. 2017. aastaks oli taastuvenergia osakaal jõudnud
29,2%-ni. Suurima osakaaluga Eesti energiaportfellis on jäätmeenergia ja tuuleenergia,
kuid suurimat arengut prognoositakse tuule- ning päikeseenergiale. Jõgede väikese
hüdroenergilise potensiaali tõttu on uute hüdroelektrijaamade rajamine piiratud, mistõttu
jääb see energiaallikas tulevikus pigem tahaplaanile. Lisaks on näha, et jäätmete
kütteväärtus sarnaneb põlekivile, kuid samal ajal kui jäätmetest energia tootmisel
vähenevad Eesti prügivarud, siis põlevkivi kasutamisel kuhjuvad erinevad jäätmed. 2030.
aastaks plaanib Eesti jõuda tasemele, kus 50% vajaminevast energiast toodetakse
taastuvate allikate poolt ning vähemalt 14% transpordi sektoris kasutatavatest kütustest
tuleb taastuvatest allikatest.
Energetic independency is a important part of a country’s independency and security. For some time oil shale has given Estonia that independence, but it’s harmful effects on the environment has pushed the country to convert more and more into renewable energy sources. The aim of this Bachelor’s thesis is to give an overview of the status of Estonian renewable energy and it’s future plans. The usage of different databases and yearbooks in this thesis give an overview how the share of renewable energy sources has changed in time. It is also shown how the percentages have changed in different types of renewable energy sources and how they have developed in time. By the year 2017 the useage of renewable energy sources reached 29,2%. The biggest producers of renewable energy are energy from waste and wind power, but solar power and wind power carry the potential of becoming the biggest source of energy. The small hydro power potential in Estonian rivers has caused a stop in the developement of new hydro power stations and all of this has put the future of hydro power in to the background of renewable energy sources. The data also shows that the calorific value of oil shale and municipal waste are at the same value, unlike oil shale, the usage of municipal waste as a source of energy reduces the amounts of waste at waste grounds. Estonia has a plan to reach a point where the usage of renewable energy reaches 50% of all power created, also 14% of the fuels in transport section must come from renewable sources by the year 2030.
