Emongweni wokuguquka kwamandla emhlabeni jikelele, amandla avuselelekayo abe yindawo ebalulekile. Phakathi kwale mithombo, amandla kagesi aphuma emanzini avelele ngenxa yezinzuzo zawo eziningi, athatha isikhundla esibalulekile emkhakheni wamandla.
1. Izimiso Zokukhiqiza Amandla Kagesi
Isimiso esiyisisekelo sokukhiqizwa kukagesi ngamanzi ukusebenzisa umehluko wamazinga amanzi bese uwasebenzisa namajeneretha kagesi ukuze kukhiqizwe ugesi. Kalula nje, kuguqula amandla angaba khona amanzi abe amandla omshini bese kuba amandla kagesi. Lapho amanzi amaningi egeleza esuka ezindaweni eziphakeme aye ezindaweni eziphansi, ugesi onamandla uqhuba i-turbine, yona ejikeleza i-generator rotor, inqume imigqa yamagnetic field ukuze ikhiqize ugesi.
Isibonelo, iSiteshi sikagesi samanzi iThree Gorges sivimba uMfula iYangtze ngedamu, okwenza kube nomehluko omkhulu ezingeni lamanzi. Ukugeleza kwamanzi okuqhubekayo kuqhuba ama-turbine, okuvumela ukukhiqizwa kukagesi okukhulu.
2. Izinzuzo Zamandla Amanzi
(1) Imvelo Evuselelekayo
Amanzi ayimithombo ejikeleza njalo eMhlabeni. Uma nje imisebe yelanga kanye namandla adonsela phansi oMhlaba kukhona, umjikelezo wamanzi ngeke ume. Lokhu kusho ukuthi imithombo yamanzi esekela amandla kagesi angaphansi komhlaba ayinakuphela, ngokungafani namafutha emvelo afana namalahle namafutha. Ngakho-ke, amandla kagesi angaphansi komhlaba ahlinzeka ngokunikezwa kwamandla okusimeme esintwini.
(2) Ihlanzekile futhi inobungani nemvelo
Ukukhiqizwa kukagesi ngamanzi akukhiqizi ukukhishwa kwamagesi okushisa noma ukukhulula ukungcola okufana nentuthu kanye ne-sulfur dioxide, okubangela umthelela omncane emvelweni. Lokhu kubaluleke kakhulu ekunciphiseni ukuguquka kwesimo sezulu emhlabeni wonke kanye nokuthuthukisa ikhwalithi yezemvelo. Ngokuphambene nalokho, izitshalo zamandla ezivamile ezisebenzisa amalahle zikhipha inani elikhulu le-carbon dioxide ngesikhathi sokusha, okwandisa ukufudumala komhlaba.
(3) Ukuqina Okuphezulu
Uma kuqhathaniswa neminye imithombo yamandla avuselelekayo njengamandla elanga nawomoya, amandla kagesi angaphansi kwamanzi awathinteki kakhulu ngokuguquguquka kwemvelo. Uma nje izindawo zokugcina amanzi zinesitoreji esanele samanzi, ukukhiqizwa kwamandla kungalawulwa kancane kancane ukuze kuhlangatshezwane nezidingo zikagesi ezahlukahlukene, kuhlinzekwe ukwesekwa kwamandla okuthembekile kumagridi kagesi.
(4) Izinzuzo Eziningi Eziphelele
Ngale kokukhiqizwa kukagesi, amaphrojekthi kagesi wamanzi anikeza nezinzuzo ezifana nokulawula izikhukhula, ukunisela, ukuhamba ngemikhumbi, kanye nokuhlinzekwa kwamanzi. Isibonelo, amadamu angagcina amanzi ngezikhathi zezikhukhula, okunciphisa izingozi zezikhukhula ezingezansi. Ngesikhathi sesomiso, angakhipha amanzi ukusekela ukunisela kwezolimo kanye nezidingo zamanzi asekhaya.
3. Isimo Samanje Sokuthuthukiswa Kwamandla Kagesi Agelezayo
Njengamanje, amazwe amaningi emhlabeni jikelele athuthukisa futhi asebenzisa izinsiza zamandla kagesi ngenkuthalo. I-China ingumkhiqizi omkhulu wamandla kagesi kagesi emhlabeni, ngamaphrojekthi amakhulu afana ne-Three Gorges Dam kanye ne-Baihetan Hydropower Station enza ngcono kakhulu isakhiwo samandla sikazwelonke. Emhlabeni jikelele, amazwe afana neBrazil neCanada nawo athembele kakhulu kumandla kagesi kagesi ekuxubeni kwawo kwamandla.
Kodwa-ke, ukuthuthukiswa kwamandla kagesi angaphansi kwamanzi kubhekene nezinselele ezithile. Ngakolunye uhlangothi, amaphrojekthi amakhulu kagesi angaphansi kwamanzi adinga ukutshalwa kwezimali okukhulu kanye nezikhathi zokwakha ezinde. Ngakolunye uhlangothi, ukuthuthukiswa kwamandla kagesi angaphansi kwamanzi kungathinta imvelo, njengokushintsha imvelo yemifula kanye nokuthinta ukufuduka kwezinhlanzi. Ngakho-ke, kubalulekile ukulinganisela ukuthuthukiswa kwamandla kagesi angaphansi kwamanzi nokuvikelwa kwemvelo kanye nokusimama.
4. Amathemba Esikhathi Esizayo Amandla Kagesi Angaphansi Komhlaba
Ngokuthuthuka okuqhubekayo kwezobuchwepheshe, ukusebenza kahle nokuthembeka kwamandla kagesi asebenzisa amanzi kuzothuthuka kakhulu. Ukuthuthukiswa kobuchwepheshe obusha be-turbine kanye nokuhlanganiswa kwamagridi ahlakaniphile kuzokwenza amandla kagesi asebenzisa amanzi ahlanganiswe kangcono ohlelweni lwamandla. Ngaphezu kwalokho, amaphrojekthi kagesi wamanzi amancane nawancane azothola ukunakwa okwengeziwe, ahlinzeke ngogesi osabalele ezindaweni ezikude futhi asekele intuthuko yezomnotho yendawo kanye nekhwalithi yokuphila.
Njengomthombo wamandla avuselelekayo othembekile, amandla kagesi asebenzisa amanzi adlala indima ebalulekile ekuhlangabezaneni nezidingo zamandla, ekulweni nokushintsha kwesimo sezulu, nasekukhuthazeni ukukhula komnotho. Kufanele sikhulise izinzuzo zawo ngenkathi sibhekana nezinselelo zawo, siqinisekise intuthuko eqhubekayo nenempilo yamandla kagesi asebenzisa amanzi.
