SILLUTAME TEED TAASTUVATE ENERGIAALLIKATE
ULATUSLIKULE KASUTAMISELE. Tartus Eesti Põllumajandusülikooli aulas toimus 4. novembril 1999. a. Eesti säästliku
arengu edendamisele pühendatud konverents
TAASTUVATE ENERGIAALLIKATE UURIMINE JA KASUTAMINE I,
millest võttis osa 250 inimest. Käesolev kogumik sisaldab selle konverentsi
ettekannete ja pikemate sõnavõttude tekste.
Kaasaegne elukorraldus ja silmapaistvad tehnilised saavutused tuginevad suuresti
fossiilsete energiaressursside (eriti naftatoodete) kasutamisele. Edasine areng vajab
järjest rohkem energiat, kuid taastumatute looduslike ressursside varud on piiratud.
Pealegi saastab nende kasutamine loodust ja viib atmosfäärist välja eluks vajalikku
hapnikku. Nafta tootmine hakkab varude lõppemise tõttu paratamatult vähenema juba
umbes kahekümne aasta pärast ja ega meil Eestiski senise ekspluateerimise juures häid
põlevkivilademeid palju kauemaks jätku. Seejuures on põlevkivi nii elektrijaamade
kütus kui ka oluline keemiatööstuse toore, mille väärtus nafta hinna tõustes ja tema
turuosa vähenedes suureneb.
Inimkonna energiatarbe rahuldamine on võimalik päikeseenergia ja tema poolt
käivitatud protsesside (tuul, veevool, taimede biomassi süntees) kasutamise abil.
Nende eelduste kasutamise ulatuse määravad piirkonna looduslikud olud, sotsiaalsed
tingimused ja majanduslik otstarbekus. Kuigi viimasel aastakümnel on alanud
taastuvate energiaallikate kasutamise kiire kasv, võtab nende osakaalu jõudmine
pooleni üldtarbest siiski aastakümneid.
Eesti on asunud säästva arengu teele, mis peab kindlustama arengu ja tervisliku
elukeskkonna ka kaugemas tulevikus. Meil on suured päikese- ja tuuleenergia varud
ning head eeldused biomassi tootmiseks. Seetõttu avaneb meile avar tegevusväli
rahvuslike loodusrikkuste otstarbekohaseks kasutamiseks. See aga nõuab uusi teadmisi
ja oskusi, loodusesõbraliku ellusuhtumisega inimesi ning mitmekülgseid teaduslikke,
tehnilisi ja rakenduslikke uuringuid. On tarvis asjalikku rahvusvahelist koostööd ja
soovi ning otsusekindlust rahvusliku tööstuse arendamiseks. Pole mingit alust arvata,
et tehniline progress taastuvate energiaallikate kasutamise alal on lõpule jõudmas ja
meie inimeste looval vaimul pole siin enam midagi teha.
Tahaks loota, et nimetatud konverents, kus moodustati ka Eesti Taastuvenergeetika
Nõukogu ellukutsumise initsiatiivrühm, pani aluse pikale tegudereale
taastuvenergeetika valdkonnas. Käesolevas kogumikus toodud tööd annavad oma
panuse teabe levitamiseks sel alal Eestis ja toetavad siin uute ideede sündi. Valdur Tiit, Eesti Põllumajandusülikool
PAVING THE WAY FOR THE WIDESPREAD USAGE OF RENEWABLE ENERGY SOURCES. 250 people attended the conference "INVESTIGATION AND USAGE OF RENEWABLE ENERGY SOURCES I", which was devoted to sustainable development promotion in Estonia and took place in Tartu at Estonian Agricultural University on November 4, 1999. This is a collection of materials presented at the Conference. Modern lifestyle and outstanding technical achievements are strongly based on usage of fossil energy sources, especially oil products. Development demands an increasing amount of energy, but the supplies of non-renewable natural resources are limited. Moreover, their usage pollutes the environment and conveys vital oxygen out of the atmosphere. Due to supplies run out the production of fossil fuels will inevitably decrease already after 20 years. The same is likely to happen with Estonian oil shale resources, which is not only a fuel for electric power stations, but also an important staple of chemical industry. And after the rise of oil prices and its fall in market share, oil shale will have even greater value. To satisfy mankind’s energy demand we have to take solar energy and processes started by solar (wind, flowing water, synthesis of plants’ biomass) more into use. The spread of their usage is determined by region’s natural and social situation, and economic expediency. Although rapid growth in using renewable energy sources has started, it will take decades to raise their share over half of total energy use. Estonia has chosen the path of sustainable development, which should guarantee development and healthy environment also in the farther future. There are great solar and wind energy resources plus good assumptions for producing biomass in Estonia. However, for efficient use of national natural resources we need more knowledge and skills, people with environment friendly attitude and extensive scientific, technical and applied investigations. In addition we have to advance sensible international cooperation as well as national industry of this field. The technical progress concerning renewable energy usage has a long way to go, which could apply also Estonians. The undersigned hopes that the Conference, where the initiative group for founding Estonian Renewable Energy Council was also instituted, was a great starting point for active and fruitful work in this sphere. This collection helps to disperse information of the kind in Estonia and support the creation of new ideas. Valdur Tiit, Estonian Agricultural University
