Ukuhlaziywa kuyaqhubeka ukuqhubela phambili kukhuphiswano kwiimarike zehlabathi ngenxa yenyani yokuba iindleko zabo ziya zisanda kwaye ukusebenza kwabo kukhulu. Umceli mngeni wamandla ahlaziyekayo ngoku kukuphucula kunye nokuyila iinkqubo zokugcina ezenza ukuba babe nakho ukubanakho ukuzihlanganisa kuthungelwano lombane ngendlela efanelekileyo nelula.
Njengoko kusaziwa ngokuthetha ngamanye amaxesha, ukugcinwa kwamandla ahlaziyekayo kuyabiza kwaye kunzima kakhulu. La mandla anokuvelisa isivuno phantse zifane neefosiliNangona kunjalo, azinakugcinwa okanye zihanjiswe zisiwe kwiindawo ezikude nemveliso yazo. Ingaba ilizwe lizimisele ukwenza ntoni xa kujongwa lo mceli mngeni?
Impumelelo yokuhlaziywa
Amandla ahlaziyekayo akakhawulelwanga kuphela ekuvelisweni kwamandla ombane, kodwa avumela ukuveliswa kobushushu okanye amafutha. Ezi zicelo zenza olu hlobo lokufumana amandla acocekileyo kukhuphiswano kwaye zikhokele imarike yamandla ehlabathi. Kuya kufuneka sithathele ingqalelo ukuba amandla ahlaziyekayo anezibonelelo zokusingqongileyo zokungangcolisi, ukunceda ukulwa nokutshintsha kwemozulu, azikhuphi gesi, njl.
Akuseyothusi ukuva ukuba ixabiso lombane lenyuka kuba "Umoya awukhange uvuthe" okanye kuba "ilanga alikaphumi". Ke ngoko, le mpumelelo yokuhlaziywa ayinakuphikwa, ngaphandle kokuba iminyaka embalwa idlulile. Kule mihla, kwiinkampani ezininzi, ukukhetha amandla ahlaziyekayo kuphantse kwabiza ixabiso eliphantsi kunokukhetha izinto zokubasa, kwaye ekuhambeni kwexesha, kunenzuzo ngakumbi kwaye kuyayihlonipha imeko-bume.
Amanani ayazithethela. Amandla omoya kunye nelanga amandla e-photovoltaic ayaqhubeka nokunyusa amandla afakiweyo. Ngo-2015, Inikwe ingxelo malunga ne-77% yofakelo olutsha kwihlabathi liphela, ngelixa i-hydroelectric yayiyeyona nto iphambili kwi-23% eseleyo. Olu phuhliso lubekho ngenxa yendleko eziphantsi zale teknoloji, ezinako ukuvelisa umbane ngexabiso (€ / kWh) ngaphantsi kwazo zonke iinkqubo eziqhelekileyo.
Umceli mngeni kwixesha elizayo
Umceli mngeni omkhulu wokuvuselelwa kwixesha elizayo, ngaphandle kwamathandabuzo, ukulawula nokugcina. Umbane uveliswa yimithombo evuselelekayo ayinakugcinwa ngexabiso elifanelekileyo, kunokuba inezithintelo ezininzi. Njengoko kungelulanga okanye kungoqoqosho ukuyigcina ngokuthe ngqo njengombane, kunyanzelekile ukuba uyiguqule ibe ngamandla oomatshini (ukumpompa amanzi, iiflaya ezinamavili ...), imichiza (iibhetri, izibaso ...) okanye umbane (ii-supercapacitors) emva koko utshintshe kwakhona.
Ke ngoko, umceli mngeni kwizazinzulu kunye neenjineli kwihlabathi liphela kukufumana indlela yokugcina amandla.
