Ibhethri yesitoreji samandla sasekhaya

Izindleko zesistimu yebhethri zehle ngaphezu kuka-80% eminyakeni engu-5 edlule futhi ziyaqhubeka nokwehla. Enye yezindawo ezithembisayo kakhulu zokwehliswa okwengeziwe kwezindleko ukugcinwa kwamandla

futhi izoba yingxenye yohlelo olukhulu kakhulu lokuphatha amandla (inethiwekhi), olungase luhlanganise ukukhiqizwa okusabalalisiwe nokulawulwa komthwalo. Ukugcinwa kwamandla ezakhiweni zezentengiselwano kuyindawo enikeza amathuba amahle kakhulu okwehlisa izikweletu zezinsiza, ukunciphisa ukuncika emafutheni ezinto ezimbiwa phansi, futhi kunciphise ukucisha okungaba khona okubangelwa ukunqamuka kukagesi.

Amabhethri okugcina amandla awakasetshenziswa kakhulu ezakhiweni zezentengiselwano ngenxa yokuthi ayabiza futhi avalelwe ezintweni ezincane ezifana nokunikezwa kwamandla okusekela, kodwa kunentshisekelo enkulu phakathi kwabahlali bezakhiwo ekusetshenzisweni kwawo ngesikhathi samahora aphakeme lapho amanani kagesi ephakeme kakhulu.

Amabhethri okugcina amandla angasiza noma isiphi isakhiwo esiphehla amandla elanga noma omoya ngokugcina ugesi owedlulele okhiqizwa ngezikhathi zesidingo esiphansi futhi awusebenzise ukusiza ukunciphisa ukusetshenziswa kwamandla ngesikhathi samahora aphakeme.

Amabhethri okugcina amandla ngeke nje anciphise izindleko zokusebenza kwezakhiwo zezentengiselwano, kodwa anikeze ithuba lokuthi lezi zakhiwo zizimele ngokwezimali ezinkampanini ezisetshenziswayo.

Ukusetshenziswa kwendawo yokugcina amandla esikalini esincane kuya ngokuya kukhanga njengendlela yokunciphisa izindleko zamandla kanye nokwenza imithombo evuselelekayo evuselelekayo efana nama-photovoltaics (PV) nama-wind turbines avame ukubonwa njengabiza kakhulu noma ahamba kancane ukuze asebenze njengokushintshwa okusebenzayo kwendabuko. Ukunikezwa kwamandla kagesi axhumeke kugridi.

Ukugcinwa kwamandla esizeni kuvumela izindleko zokuqiniswa ezihlehlisiwe noma ezigwenywe, ukonga izindleko ezinkulu, ukwanda kokusebenza kahle kwezinhlelo ze-PV, ukuncipha kokulahlekelwa kolayini, isevisi ethembekile ngaphansi kokunqamuka nokucinywa, kanye nokuqalisa ngokushesha izinhlelo eziphuthumayo.

Umgomo wesikhathi esizayo ukuqapha impilo yebhethri njengoba ukusetshenziswa kwalawa mabhethri bekukhula eminyakeni edlule. Lokhu kungaba yindlela yokuthola ukuthi zisetshenziswa ngendlela eqhubekayo noma cha.

Ukusetshenziswa kwalawa mabhethri akuncikile nje kuphela esikhathini sokuphila kwawo kodwa nakwezinye izici njengokuthi mangakanani amandla awagcinayo nokuthi ngasiphi isikhathi, lolu lwazi luphinde luboniswe kugrafu engenhla evela ocwaningweni lwangaphambili olwenziwa abacwaningi ePenn. I-State University eshicilele iphepha elichaza ukuthi amabhethri anenani eliphelele lemijikelezo lapho kufanele afinyelele ukusebenza kahle kwawo okuphezulu.

Ngokuphambene kukhona ezinye izifundo ezithi nakuba ngemva kokufinyelela lelo nani lemijikelezo iqala ukubola, amabhethri angahlelwa kabusha kalula ukuze afinyelele inombolo efiselekayo yemijikelezo.

Ngokuzimele ekuhlanganisweni noma ekuhlanganisweni kabusha, ucwaningo lokwehliswa kwesithunzi kufanele lwenziwe ukuze kutholwe ukuthi luhamba kanjani ngemva kwesikhathi esithile futhi uma kukhona ukwehla ekusebenzeni kwayo konke ukuphila. Lokhu akukenziwa yinoma iyiphi inkampani kodwa kungaba yinzuzo kubo ngoba ukwazi ubude bempilo obulindelwe bebhethri ngalinye, bangalungisa imikhiqizo yabo ngokufanele.

Isiphetho se ibhethri yokugcina amandla ekhaya

Lawa mabhethri ayabiza yingakho izinkampani zingafuni ukuthi ehluleke ngaphambi kwesikhathi; kulapho-ke ukubaluleka kokuthola ukuthi zigcina isikhathi esingakanani zikhona. Ucwaningo oluningi seluvele lwenziwe kulawa mabhethri uma kukhulunywa ngomthamo ngokuhamba kwesikhathi (ngamaphesenti) njengalokhu okukhonjiswe kumfanekiso6.

Ukuziphatha okuvamile kwebhethri ukwenyuka, ukuphakama kanye nokubola ngemva kwesikhathi esithile, lokhu kuboniswe nakwezinye izifundo. Kubalulekile ukuthi abakhiqizi bazi ukuthi amabhethri abo aseduze nesikhathi sabo sokuphila esilindelekile, ukuze bakwazi ukuwashintsha ngaphambi kokuthi aqale ukuwohloka.
