UHLOBO LWEZITYELELO ZAMANDLA VS. IINDLEKO
Omnye wemiba engundoqo echaphazela iindleko zokwakha kumaziko okuvelisa umbane luhlobo loncedo olucetywayo. Iindleko zokwakha zinokwahluka kakhulu ngokuxhomekeke ekubeni ziziziko zombane ezibaswa ngamalahle okanye zisebenza ngegesi yendalo, isola, umoya, okanye izibonelelo zejenereyitha yenyukliya. Kubatyali-mali kumaziko okuvelisa umbane, iindleko zokwakha phakathi kwezi ntlobo zezixhobo zokuvelisa yinto ebalulekileyo eqwalaselwayo xa kuvavanywa ukuba ingaba utyalo-mali luya kuba nengeniso kusini na. Abatyali-zimali kufuneka kwakhona bathathele ingqalelo eminye imiba, efana neendleko zogcino oluqhubekayo kunye nemfuno yexesha elizayo ukuze kumiselwe izinga elifanelekileyo lembuyekezo. Kodwa eyona nto iphambili kulo naliphi na ubalo ziindleko ezinkulu ezifunekayo ukuzisa isixhobo kwi-intanethi. Ngokunjalo, ingxoxo emfutshane yeendleko zokwakha zokwenyani kwiindidi ezahlukeneyo zezityalo zamandla yindawo eluncedo yokuqalisa ngaphambi kokuphonononga ezinye iintshukumo eziphembelela iindleko zokwakha iplanti yamandla.
Xa uhlalutya iindleko zokwakha iplanti yamandla kubalulekile ukukhumbula ukuba iindleko zokwakha eziqatshelweyo zinokuphenjelelwa ngamanani amaninzi. Ngokomzekelo, ukufikelela kwizibonelelo eziqhuba ukuveliswa kwamandla kunokuba nefuthe elikhulu kwiindleko zokwakha. Izixhobo ezifana nelanga, umoya, kunye ne-geothermal zisasazwa ngokungalingani, kwaye iindleko zokufikelela kunye nokuphuhlisa ezi zixhobo ziya kunyuka ngokuhamba kwexesha. Abangena kwangoko kwimarike baya kubamba olona fikelelo luneendleko eziphantsi kwizibonelelo, ngelixa iiprojekthi ezintsha zinokuhlawula kakhulu ukufikelela kwizibonelelo ezilinganayo. Ubume bolawulo lwendawo yomzi-mveliso wamandla bunokuba nefuthe elikhulu kwixesha elikhokelayo leprojekthi yokwakha. Kwiiprojekthi ezinotyalo-mali olunzima ekwakhiweni oku kunokukhokelela ekwandeni kwenzala eyongezelekayo kunye neendleko zolwakhiwo ngokubanzi. Ngolwazi oluthe kratya malunga nentaphane yezinto ezinokuphembelela iindleko zolwakhiwo lwemizi-mveliso yamandla, jonga kwiiNtelekelelo zeNdleko eyiNkunzi yeZityalo zokuVelisa uMbane eziDityanisiweyo ezikhutshwe yi-US Energy Information Administration (EIA) ngo-2016.
Iindleko zokwakha oomatshini bombane ziboniswa njengexabiso ngeedola ngekilowatt nganye. Ulwazi oluthiwe thaca kweli candelo lubonelelwe yi-EIA. Ngokukodwa, siza kusebenzisa iindleko zokwakhiwa kwendawo yombane kumaziko okuvelisa umbane akhiwe ngo-2015, afumaneka apha. Olu lwazi lolona lwazi lukhoyo ngoku, kodwa i-EIA kulindeleke ukuba ikhuphe iindleko zokwakhiwa kweplanti yombane ngo-2016 ngoJulayi ka-2018. Kwabo banomdla kwiindleko zokwakha oomatshini bombane, upapasho lwe-EIA ngomnye wemithombo yolwazi exabiseke kakhulu ekhoyo. Idatha enikezelwe yi-EIA iluncedo ukubonisa ubume obuntsokothileyo beendleko zokwakha umzi-mveliso wamandla, kwaye iqaqambisa intaphane yezinto eziguquguqukayo ezingenako ukuchaphazela kuphela iindleko zokwakha iziko lombane kodwa kunye nenzuzo eqhubekayo.
IINDLEKO ZOKUSEBENZA NEZOMTHETHO
Umsebenzi kunye nezixhobo zimbini zezona zinto ziqhuba iindleko zokwakhiwa kweplanti yamandla, kwaye zombini zikhokelela ekunyukeni kweendleko zokwakha unyaka ngamnye kuwo onke amashishini. Ukugcina ungqameko oluguquguqukayo kubo bobabini abasebenzi kunye nemathiriyeli kubalulekile xa kuhlolwa iindleko zizonke zokwakhiwa kwezixhobo zombane. Ulwakhiwo lweplanti yombane ngokuqhelekileyo luxanduva olwandisiweyo. Iiprojekthi zinokuthatha phakathi kweminyaka emi-1 ukuya kwemi-6 ukuba zigqitywe ubuncinci, ezinye zongezeleleka ngakumbi. I-EIA ichaza ngokufanelekileyo ukuba iyantlukwano phakathi kweendleko eziqikelelwayo kunye nezokwenyani zemathiriyeli kunye nokwakhiwa ngexesha leprojekthi kubalulekile ukuqwalaselwa kwaye kunokuba nempembelelo enkulu kwiindleko zokwakha.
Iindleko zokwakha ngokubanzi ziyenyuka, kodwa ezimbini zabaqhubi abaphambili kule nto yimpahla kunye nomthwalo wabasebenzi. Iindleko zezinto eziphathekayo zinyuke kakhulu kwiinyanga zamva nje, kwaye zingaqhubeka nokunyuka ukuba iimeko zomgaqo-nkqubo zangoku zigcinwe. Ngokukodwa, imirhumo yokungeniswa kumazwe angaphandle kweentsimbi eziphambili, kubandakanywa intsimbi, i-aluminiyam, kunye nentsimbi, kunye namaplanga avela eKhanada, avelisa ukuguquguquka okumangalisayo kweendleko zempahla. Iindleko zemathiriyeli yokwenyani ngoku malunga ne-10% ngaphezulu kweyeKhala ngo-2017. Le meko ayibonakali ngathi iyancipha kwikamva elibonakalayo. Intsimbi ibaluleke kakhulu kulwakhiwo lwemizi-mveliso yombane, ngoko ke imirhumo eqhubekayo kwintsimbi ephuma kumazwe angaphandle inokukhokelela ekunyukeni kweendleko ezinkulu zolwakhiwo lweplanti yombane yazo zonke iindidi.
Ukunyuka kweendleko zabasebenzi kushishino lokwakha nako kunegalelo ekunyukeni kweendleko zokwakha. Ukunyuka kweendleko zabasebenzi kuqhutywa kukunqongophala kwabasebenzi abanezakhono abasuka kumanani asezantsi eenkulungwane kurhwebo lokwakha kunye nokuncipha okumangalisayo kwabasebenzi bokwakha ngexesha nasemva kokudodobala koqoqosho. Nangona iifemu ezininzi zokwakha zidibanisa iinkqubo zekhondo lomsebenzi ukurhwebesha iminyaka eyiwaka leminyaka kumashishini orhwebo, kuya kuthatha ixesha ukubona ngokupheleleyo isiphumo sezi nzame. Oku kunqongophala kwabasebenzi kubonakala ngokucacileyo kwimimandla yasezidolophini apho kukho ukhuphiswano oluqatha lwabasebenzi abanezakhono. Kwiiprojekthi zolwakhiwo lwemizi-mveliso yombane kufutshane namaziko asezidolophini, ukufikelela kubasebenzi abanezakhono kunokuthintelwa kwaye kunokuza ngexabiso eliphantsi.
