Namuhla sigubha Usuku Lomhlaba Wezilwandle. Ngalolu suku sikhumbula ukubaluleka kanye nomthelela omkhulu olwandle olunalo ezimpilweni zethu nakwezabo bonke abantu abaphilayo emhlabeni. Singasho ukuthi ngaphandle kwabo, impilo ibingeke ifane. Ngenxa yabo singaphefumula umoya-mpilo, ngoba cishe bawumthombo wokuqala wokukhiqizwa kwalo gesi odingekayo emhlabeni wonke. Iphinda futhi imunce inani elikhulu lekhabhoni esilikhiphela emkhathini emisebenzini yethu, isinikeze ukudla nezinsizakusebenza, futhi isekele impilo engaphakathi kuyo.
Futhi, ngenxa yolwandle singakwazi ukukhiqiza amandla avuselelekayo. Kunezinhlobo eziningi zamandla avuselelekayo esingazithola olwandle. Inzuzo enayo ukuthi ingamandla asimeme ngokuphelele, ahlanzekile futhi, ngokusobala, amandla angapheli. Ngabe ufuna ukwazi ukubaluleka ngamandla kwezilwandle?
Yini esiyisebenzisa ngokunenzuzo olwandle ukuthola amandla?
Into esemqoka esiyisebenzisayo olwandle ukuze sikwazi ukukhiqiza amandla avuselelekayo yimimoya, amagagasi namagagasi. Ngenxa yalezi zinto singakhiqiza amandla ahlanzekile ngekusasa lesizukulwane esisha. Ukukhiqizwa kwamandla avuselelekayo kungenye yezinsiza ezibaluleke kakhulu olwandle olunazo kubantu, ngoba sidinga amandla ukuze sikwazi ukwenza imisebenzi yethu.
Ngaphezu kwalokho, akulona ulwandle kuphela olusisizayo ukuthola amandla, kodwa futhi lungasebenza njengesisekelo sokuthola olunye uhlobo lwamandla avuselelekayo njengamandla omoya. Ukuthuthukiswa kwamapulazi omoya asogwini lolwandle kuyinzuzo enkulu maqondana nokuhlala kwendawo nokusetshenziswa kwemisinga nemimoya eyakha amagagasi. Kwingqalasizinda ekhiqiza amandla avuselelekayo ngendlela ethembekile neqhubekayo, kufanele kubhekelwe lokho ayithinti indawo entekenteke yasolwandle.
Siyazi ukuthi imithelela yezemvelo olwandle njengokungcola, umsindo owedlulele, oplastikhi nezinye izinto esizibangelayo zingathinta imvelo yasolwandle ngokungenakuhlehliseka. Kungakho imisebenzi yokuxhashazwa kwamandla okwenziwa olwandle kumele ihlale yenziwa ngokuhlolwa kwemithelela yezemvelo esingayibanga.
Siwakha kanjani amandla avuselelekayo olwandle?
Njengoba sishilo ngaphambili, kunezinhlobo eziningana zamandla avuselelekayo esingazikhiqiza olwandle. Enye yale mithombo yomoya engenhla yasogwini eshiwo ngenhla, enye amandla olwandle (eyaziwa ngokuthi amandla asolwandle), enye leyo ikhiqizwa ngamagagasi (amandla amaza) futhi, ekugcineni, singasebenzisa amandla emisinga yasolwandle.
Amandla omoya we-Offshore atholakala ngama-wind turbines afana kakhulu nalawo asetshenziswa emhlabeni. Aqondiswe olwandle futhi kuyadingeka ukuthi amanzi ajulile ukuze akwazi ukufaka amapulatifomu antantayo abamba imishini yomoya. Ngenxa yokwanda kwezobuchwepheshe, ukuthuthukiswa kanye nocwaningo lwalezi zinjini zomoya, zingabekwa ngokuqhelelene kakhulu ukusuka ogwini, lapho umoya uphakeme kakhulu ngakho-ke amandla amaningi angatholakala ngemali ephansi.
Ngokuphathelene namandla esingawathola ngamagagasi, imisinga kanye namagagasi, singasho ukuthi yimishini edonsa amandla ukukhiqiza ugesi. Imayelana ne- ukusetshenziswa kwama-buoys, ama-clam system afana ne-shells phansi kolwandle, noma kuma-turbines angaphansi kwamanzi afana nama-wind turbines. Ngenxa yalezi zinhlelo, amandla avuselelekayo angatholakala.
Izinzuzo zokuthola amandla ezilwandle zethu
Enye yezinzuzo ezinhle zokuthola amandla olwandle lwethu inani lemisebenzi emisha nezinkampani ezintsha ezingadalwa futhi ezikhulayo ngenxa yalobu buchwepheshe obusha obungena ezimakethe. Enye inzuzo ukuthi amandla akhiqizwayo yi- ihlanzekile ngokuphelele futhi iyaqhubekaNgakho-ke, singasiza ekunciphiseni imiphumela yokuguquka kwesimo sezulu ngokunciphisa inani lamagesi abamba ukushisa esiwakhipha emkhathini.
Ekugcineni, sibonga iqiniso lokuthi ulwandle luzoba ngumthombo wamandla obaluleke kakhulu, luzosisiza ukuthi silunikeze inani elithe xaxa futhi sikwazi ukulivikela kangcono. Ukonga izilwandle zethu kubaluleke kakhulu ezimpilweni zethu nakwezabo bonke abantu abaphilayo emhlabeni.
