Hydro energy - renewable energy source

Voda je naravna dobrina, ki je pogoj življenja na Zemlji. Je brezbarvna tekočina, brez vonja in okusa. Danes pokriva tri četrtine površja Zemlje. Voda na Zemlji neprestano kroži, se spreminja in obnavlja. Pojavlja se v različnih agregatnih stanjih, trdem kot led, tekočem kot voda in plinastem, kot vodna para. V diplomi je predstavljeno izkoriščanje vode nekoč in danes. Opisana so prva izkoriščanja vode s pomočjo naprav, kot so sakija, vodno kolo, parni stroj. Danes vodo izkoriščamo predvsem v konvencionalnih in v nekonvencionalnih elektrarnah. Konvencionalne elektrarne so elektrarne, katerih je več vrst, pretežno pa izkoriščamo kinetično in potencialno energijo rek. Nekonvencionalni energijski viri pa so elektrarne, ki izkoriščajo energijo plime in oseke oziroma plimovanja, energijo valov, energijo morskih tokov in toplotno energijo morja. V diplomi sem podrobneje opisala konvencionalne vrste objektov za izkoriščanje vodne energije ter njihove prednosti in slabosti. Prav tako pa sem podrobneje opisala tudi naprave, ki izkoriščajo nekonvencionalne energijske vire. Zadnji del diplome sem namenila prenosu teoretičnega spoznanja diplomskega dela v prakso, v osnovno šolo. Analizirala sem v katerih razredih osnovne šole in pri katerih predmetih bi lahko uporabila teoretična spoznanja diplome. Tako sem analizirala učni načrt ter pripravila učni vsebini za pouk. Prva priprava na vzgojno – izobraževalno delo se nanaša na uro obravnavanja in osvajanja nove snovi s področja energije in energetike. Druga priprava pa predstavlja učno strategijo, ekskurzijo pri energetiki.Water is a natural resource, which is a condition of life on Earth. It is a colorless, odorless and tasteless liquid. It covers three-quarters of the Earth\u27s surface. Water on Earth is constantly circulating, it changes and renews. It occurs in different physical states, hard as ice, liquid such as water and gaseous, such as water vapor. This thesis presents the exploitation of water in both past and present. There is a description of the first uses of water with devices such as Saki, water wheel and the steam engine. Today we exploit water mainly for purposes in conventional and non-conventional power plants. Conventional power plants are power plants that utilize the kinetic and potential energy of rivers. Unconventional energy sources are power plants using energy ebb and flow or tidal, wave energy, ocean currents and thermal energy of the sea. I described the conventional types of facilities for the exploitation of hydropower as well as their advantages and disadvantages in this thesis. I also described in detail the devices that exploit unconventional sources of energy. The last part of the thesis is dedicated to the transfer of theoretical knowledge of the thesis into practice in elementary school. I had analyzed in which subjects taught in elementary school we could use the theoretical knowledge from the thesis. I analyzed the curriculum and prepared teaching content for lessons. The first preparation for educational work refers to the time of treatment and the assimilation of new information in the field of energy and energetics. The second preparation is about learning strategy in a form of school field trip
