Ama-Renewables aqhubeka nokuthuthuka ekuncintisaneni ezimakethe zomhlaba ngenxa yokuthi izindleko zabo ziya ngokuya zehla futhi ukusebenza kwabo kukhulu. Inselelo yamandla avuselelekayo manje ukwenza ngcono nokuklama izinhlelo zokugcina lokho kuzenza zikwazi ukukwazi ukuzihlanganisa nenethiwekhi kagesi kahle futhi kalula.
Njengoba kwaziwa ngokukhuluma kwezinye izikhathi, ukugcinwa kwamandla avuselelekayo kuyabiza futhi kunzima kakhulu. La mandla angakhiqiza isivuno kucishe kufane nophethiloli wezinsalelaNoma kunjalo, azikwazi ukugcinwa noma ukuhanjiswa ziyiswe ezindaweni ezikude nomkhiqizo wazo. Ngabe umhlaba uhlose ukwenzani ngale nselelo?
Impumelelo yokuvuselelwa
Amandla avuselelekayo awakhawulwanga kuphela ekukhiqizeni amandla kagesi, kepha futhi avumela ukukhiqizwa kokushisa noma okokubasa. Lezi zinhlelo zokusebenza zenza lolu hlobo lwamandla ahlanzekile luthole ukuncintisana futhi luhole imakethe yamandla emhlabeni. Kumele sinake ukuthi amandla avuselelekayo anezinzuzo zemvelo ngokungangcolisi, kuyasiza ukulwa nokuguquka kwesimo sezulu, ayikhiphi amagesi, njll.
Akusaxakile ukuzwa ukuthi intengo kagesi inyuka ngoba "Umoya awukaphephethi" noma ngoba "ilanga alikaphumi". Ngakho-ke, le mpumelelo yokuvuselelwa ibingenakuphikwa, yize sekudlule iminyaka embalwa. Kulezi zinsuku, ezinkampanini eziningi, ukukhetha amandla avuselelekayo kushibhile kunokukhetha ophethiloli, futhi ngokuhamba kwesikhathi, kunenzuzo enkulu futhi kuyayihlonipha imvelo.
Izinombolo ziyazikhulumela. Umoya nelanga amandla we-photovoltaic aqhubeka nokukhulisa amandla awo afakiwe. Ngo-2015, kubalwe cishe i-77% yokufakwa okusha emhlabeni jikelele, ngenkathi ugesi ophehlwa ngamanzi ubudlangile kuma-23% asele. Lokhu kuthuthukiswa kwenzeke ngenxa yezindleko eziphansi zalobu buchwepheshe, ezikwazi ukukhiqiza ugesi ngezindleko (€ / kWh) ezingaphansi cishe kwazo zonke izinhlelo ezivamile.
Inselelo ngokuzayo
Inselelo enkulu yokuvuselelwa ngokuzayo, ngaphandle kokungabaza, ukuphatha nokugcina. Ugesi ukhiqizwa ngemithombo evuselelekayo ayikwazi ukugcinwa ngenani elifanele, kunalokho linezithiyo eziningi. Njengoba kungelula noma ukonga ukuyigcina ngqo njengogesi, kuyadingeka ukuyiguqula ibe ngamandla kagesi (ukudonsa amanzi, amasondo okundiza ...), amakhemikhali (amabhethri, okokubasa ...) noma i-electromagnetic (supercapacitors) ukuze ikuguqule kamuva futhi.
Ngakho-ke, inselelo yososayensi nonjiniyela emhlabeni jikelele ukuthola indlela yokugcina amandla.
