Ukubophela amandla amagagasi kunikeza umthombo othembisayo, obikezelwayo, futhi ongashintshi wamandla avuselelekayo, ngezindlela ezisukela ezihlahleni zamagagasi kuya ezinjinini zolwandle kanye nothango lwamagagasi. Njengoba amazwe ehlose ukuthola amandla avuselelekayo ahlosiwe, amandla olwandle avela njengombambeli obalulekile, anikeza ukukhula komnotho okungaba khona, ukuvulwa kwamathuba emisebenzi, kanye nokuvikeleka kwamandla. Kodwa-ke, ukulawulwa ngokucophelela kuyadingeka ukuze kuncishiswe imithelela engase ibe khona emvelweni, okuhlanganisa nemiphumela yezilwane zasolwandle kanye nezindawo ezisogwini.

Ingqikithi yamandla olwandle

I-Tidal energy iwuhlobo lwamandla aphehlwa ngamanzi aguqula amandla atholakala emanzini abe ugesi noma ezinye izinhlobo zamandla awusizo. Iwumthombo wamandla ovuselelekayo ongabikezelwa futhi ongashintshi, ngokungafani nezinye izinhlobo zamandla avuselelekayo. Ukusebenzisa la mandla kungafezwa ngezindlela eziningi, enye yazo ngokusebenzisa amagagasi olwandle. 

I-tidal barrage uhlobo lwedamu elakhiwe ngaphesheya kwendawo evulekile yomfula. Inochungechunge lwamasango alawula ukugeleza kwamanzi ukungena nokuphuma emgodini. Njengoba igagasi lingena, amasango ayavaleka, avale amanzi endishini. Lapho amagagasi ephuma, amasango ayavuleka, avumele amanzi avaleleke ukuba aphume ngezinjini eziphehla ugesi.

Enye indlela yokusebenzisa amandla olwandle iwukusebenzisa izinjini zomoya. Ngokuvamile zifakwa olwandle ezindaweni ezinamaza anamandla. Njengoba amagagasi egeleza engena futhi ephuma, amanzi aphendulela izindwani ze-turbine, eshayela i-generator ukuze ikhiqize ugesi.

Okokugcina, uthango lwamaza olwandle lungasetshenziswa futhi ukubamba amandla olwandle. Lezi zakhiwo ziwuchungechunge lwama turbines akleliswe ngokulandelana, afana nothango. Njengoba igagasi lingena liphuma, amanzi ageleza phakathi kwezinjini zomoya, okubangela ukuba ajikeleze futhi akhiqize ugesi. Le ndlela ivame ukusetshenziswa emanzini angashoni lapho kungenzeki khona ukufaka izinjini zomoya ezingazodwana.

Umthelela ophazamisayo

Ukuthunyelwa kobuchwepheshe bamandla olwandle, okufana ne-turbine entantayo eyethulwe yi-Orbital Marine Power, kuphawula ukushintsha kwesimo samandla. Njengoba amazwe afana neScotland elwela ukuhlangabezana nezinhloso zamandla avuselelekayo, amandla olwandle angase adlale indima ebaluleke kakhulu. Njengoba amandla olwandle ebikezelwa futhi engaguquguquki, angasiza ekwehliseni ukuguquguquka kokuphakelwa kukagesi okungenzeka ngeminye imithombo evuselelekayo njengomoya nelanga, okuholela ekunqamukeni kukagesi okumbalwa kanye nokwehliswa kwezikweletu zikagesi.

Izinkampani ezisebenza ngobuchwepheshe bamandla avuselelekayo zingathola imakethe ekhulayo yemikhiqizo namasevisi azo. Labo abasezifundeni ezisogwini bangahlomula ekufakweni nasekugcinweni kwengqalasizinda yamandla olwandle, kudaleke amathuba emisebenzi. Ngaphezu kwalokho, amabhizinisi adinga amandla amaningi, njengezitshalo zokukhiqiza, angase akwazi ukuthuthela ezindaweni ezinemithombo eminingi yamandla olwandle ukuze asizakale ngezindleko eziphansi zamandla.

Kodwa-ke, ohulumeni nezinhlaka ezilawulayo zingadinga ukuphatha ngokucophelela ukwanda kwamandla olwandle ukuze kuncishiswe imithelela engaba khona emvelweni. Ukukhathazeka mayelana nomthelela empilweni yasolwandle kuvumelekile futhi kudinga ukucatshangelwa nokuqapha ngokucophelela. Amasu angabandakanya ukuklama izinjini zomoya ezinciphisa ukulimala kwezidalwa zasolwandle kanye nokwenza ukuhlola okuphelele komthelela kwezemvelo ngaphambi kokuba kugunyazwe amaphrojekthi amasha. Ukwengeza, ohulumeni bangatshala imali ocwaningweni nasekuthuthukisweni ukuze baqhubeke nokuthuthukisa ubuchwepheshe futhi banciphise indawo yabo yemvelo.

Imithelela yamandla olwandle

Imithelela ebanzi yokuvuna amandla olwandle ingase ihlanganise:

• Imisebenzi eyengeziwe yobuchwepheshe neyokulungisa njengoba izinkampani zonjiniyela basolwandle ziya ngokuya zakha izinjini zomoya, ama-barrage, nezinye izinhlobo ezahlukene zokufakwa kwamandla olwandle.
• Ukuthuthukiswa kwamamodeli e-automated turbine angakwazi ukuzihambisa ezindaweni ezihlukene zasolwandle ngokunembile ukuze abambe amagagasi njengoba kwenzeka.
• Amaphethini okufuduka okunomthelela ezilwaneni zasendle zasogwini ngenxa yokuba khona kwamaturbine namabarrage.
• Imiphakathi yasogwini eqhelile ethola amandla okusebenza ngaphandle kwegridi yamandla enkulu ngenxa yokufakwa okuzayo kwamandla e-remote turbine turbine. 
• Ukuvikeleka kwamandla okuthuthukisiwe kunciphisa ubungozi bokushoda kwamandla kanye nokuntengantenga kwentengo okuhambisana neminye imithombo yamandla.
• Ukufakwa kwengqalasizinda yamandla olwandle eshintsha izindawo ezisogwini, okungaba nomthelela ezokuvakasha nezinye izimboni ezithembele ebuhleni bemvelo.
• Abasebenzi emikhakheni yamandla endabuko njengamalahle namafutha adinga ukuqeqeshwa kabusha nokusekelwa kwabasebenzi abasuswa ezindaweni zabo.
• Umthelela ongaba khona ezinhlelweni zemvelo zasolwandle oholela emithethweni emisha nemikhawulo, okudala izithiyo ezengeziwe zokuthuthukiswa nokusatshalaliswa kobuchwepheshe bamandla olwandle.

Imibuzo okufanele icatshangelwe

• Ingabe ucabanga ukuthi amandla olwandle angaba umthombo wamandla ozwakalayo ngendlela amandla elanga nawomoya abe ngayo kusukela ngawo-2010?
• Ucabanga ukuthi isimo solwandle singathinteka kanjani ngokuphawulekayo ngokuba nezinjini zomoya eziningi eduze nogu?
