UHLOBO LWESITSHALA SAMANDLA VS. IZINDLEKO
Enye yezinto ezibalulekile ezithinta izindleko zokwakha izikhungo zokuphehla ugesi uhlobo lwesikhungo esihlongozwayo. Izindleko zokwakha zingahluka kakhulu kuye ngokuthi izimboni zamandla kagesi ngamalahle noma izitshalo ezinikwa amandla igesi yemvelo, ilanga, umoya, noma izinsiza zokuphehla amandla enuzi. Kubatshalizimali ezikhungweni zokuphehla ugesi, izindleko zokwakha phakathi kwalezi zinhlobo zezinsiza zokuphehla ziwukucatshangelwa okubalulekile lapho kuhlolwa ukuthi ukutshalwa kwezimali kuzoba nenzuzo yini. Abatshalizimali kufanele futhi bacabangele ezinye izici, njengezindleko zokunakekela okuqhubekayo kanye nesidingo sesikhathi esizayo ukuze kunqunywe izinga elivumayo lembuyiselo. Kodwa okubalulekile kunoma yikuphi ukubala yizindleko ezinkulu ezidingekayo ukuletha indawo ku-inthanethi. Kanjalo, ingxoxo emfushane yezindleko zangempela zokwakha zezinhlobo ezahlukene zezitshalo zikagesi iyisiqalo esiwusizo ngaphambi kokuhlola ezinye izinto eziguquguqukayo ezithonya izindleko zokwakha isizinda samandla.
Lapho uhlaziya izindleko zokwakha isitshalo samandla kubalulekile ukukhumbula ukuthi izindleko zokwakha eziqashiwe zingathonywa inani lezinto eziguquguqukayo. Isibonelo, ukufinyelela ezinsizeni ezishayela ukukhiqizwa kwamandla kungaba nomthelela omkhulu ezindlekweni zokwakha. Izinsiza ezifana nelanga, umoya, kanye ne-geothermal zisatshalaliswa ngokungalingani, futhi izindleko zokufinyelela nokuthuthukisa lezi zinsiza zizokhuphuka ngokuhamba kwesikhathi. Abangena kuqala emakethe bazothwebula ukufinyelela okungabizi kakhulu ezinsizeni, kanti amaphrojekthi amasha kungase kudingeke akhokhe kakhulu ngokufinyelela izinsiza ezifanayo. Indawo yokulawula yendawo yesikhungo sikagesi ingaba nomthelela omkhulu ngesikhathi sokuhola sephrojekthi yokwakha. Kumaphrojekthi anotshalomali olusindayo ekuqaleni ekwakhiweni lokhu kungaholela ekwenyukeni kwenzuzo enqwabelene kanye nezindleko zokwakha zizonke. Ukuze uthole ulwazi olwengeziwe mayelana nenqwaba yezinto ezingaba nomthelela ezindlekweni zokwakha zezimboni zikagesi, bheka Izilinganiso Zezindleko Zemali Yezimboni Ezikhiqiza Ugesi Ezisetshenziswayo ezikhishwe yi-US Energy Information Administration (EIA) ngo-2016.
Izindleko zokwakha isizinda sikagesi zethulwa njengezindleko ngamadola ngekilowatt ngayinye. Ulwazi olwethulwe kulesi sigaba luhlinzekwa yi-EIA. Ngokukhethekile, sizosebenzisa izindleko zokwakha isikhungo sikagesi ezikhungweni zokuphehla ugesi ezakhiwa ngo-2015, ezitholakala lapha. Lolu lwazi yilona olunikeziwe lwamanje kakhulu, kodwa i-EIA kulindeleke ukuthi ikhiphe izindleko zokwakha isikhungo sikagesi ngo-2016 ngoJulayi 2018. Kulabo abathanda izindleko zokwakha isikhungo sikagesi, ukushicilelwa kwe-EIA kungomunye wemithombo yolwazi ebaluleke kakhulu etholakalayo. Idatha ehlinzekwe yi-EIA ilusizo ekuboniseni ubunjalo obuyinkimbinkimbi bezindleko zokwakha isikhungo sikagesi, futhi igqamisa inqwaba yezinto eziguquguqukayo ezingenakuthikameza kuphela izindleko zokwakhiwa kwesikhungo sikagesi kodwa nenzuzo eqhubekayo.
IZINDLEKO ZOKUSEBENZA KANYE NEZINTO EZIBONAKALISAYO
Izisebenzi nezinto zokwakha ziyizisusa ezimbili ezibalulekile zezindleko zokwakha isikhungo sikagesi, futhi zombili ziholela ekukhuphukeni kwezindleko zokwakha unyaka ngamunye kuzo zonke izimboni. Ukugcina unolwazi ngokuguquguquka kwakho kokubili abasebenzi kanye nezinto zokwakha kubalulekile lapho kuhlolwa inani lezindleko zokwakha zezitshalo zikagesi. Ukwakhiwa kwesikhungo sikagesi ngokuvamile kuwumsebenzi owandisiwe. Amaphrojekthi angathatha iminyaka ephakathi ko-1 no-6 ukuthi aqedwe okungenani, kanti amanye anwebeka kakhulu. I-EIA ikhomba ngokufanelekile ukuthi umehluko phakathi kwezindleko eziqanjiwe nezangempela zezinto zokwakha phakathi nomsebenzi ubalulekile ukucatshangelwa futhi ungaba nomthelela omkhulu ezindlekweni zokwakha.
Izindleko zokwakha ngokuvamile ziyenyuka, kodwa izinto ezimbili eziyinhloko zalokhu umthwalo wempahla nomsebenzi. Izindleko zezinto ezibonakalayo zikhuphuke kakhulu ezinyangeni ezisanda kwedlula, futhi zingase ziqhubeke zikhuphuka uma izimo zenqubomgomo zigcinwa. Ikakhulukazi, amanani okuthengwa kwamanye amazwe kwezinsimbi ezibalulekile, okuhlanganisa insimbi, i-aluminium, nensimbi, kanye namapulangwe avela e-Canada, akhiqiza ukuguquguquka okumangalisayo ezindlekweni zezinto ezibonakalayo. Izindleko zezinto ezibonakalayo okwamanje zikhuphuke cishe ngo-10% ngo-Julayi 2017. Le threndi ibonakala iyancipha esikhathini esizayo esibonakalayo. Insimbi ibaluleke kakhulu ekwakhiweni kwesikhungo sikagesi, ngakho-ke amanani aqhubekayo ensimbi evela kwamanye amazwe angaholela ekwenyukeni kwezindleko zokwakhiwa kwesikhungo samandla azo zonke izinhlobo.
Ukwenyuka kwezindleko zabasebenzi embonini yezokwakha nakho kunomthelela ekukhuphukeni kwezindleko zokwakha. Ukwenyuka kwezindleko zabasebenzi kubangelwa ukushoda kwabasebenzi abanamakhono okubangelwa inani eliphansi lezinkulungwane zeminyaka emisebenzini yokwakha kanye nokuncipha okumangalisayo kwabasebenzi bokwakha ngesikhathi nangemuva kokuwohloka komnotho. Nakuba amafemu amaningi okwakha ehlanganisa izinhlelo zendlela yomsebenzi ukuze ahehe izinkulungwane zeminyaka eminingi ezimbonini zezohwebo, kuzothatha isikhathi ukubona ngokugcwele umphumela wale mizamo. Lokhu kushoda kwezisebenzi kubonakala ngokucace kakhulu ezindaweni zasemadolobheni lapho kukhona ukuncintisana okukhulu kwabasebenzi abanamakhono. Kumaphrojekthi okwakhiwa kwesikhungo sikagesi eduze nezindawo zasemadolobheni, ukufinyelela kubasebenzi abanamakhono kungase kukhawulelwe futhi kungase kubize kakhulu.
