Njengoko sonke sisazi, amandla ahlaziyekayo zivusa umdla ezininzi, abantu abaninzi. Inzululwazi ezininzi kunye nemibutho iyasilumkisa ngengxaki yokuqhubeka nokusebenzisa i-fuels.
Ngethamsanqa, kukho izixeko ezithile ezinamabhaso anokujoliswa ekujoliswe kuwo. Uninzi lwazo lucebise ukubonelela ngesixeko kwi I-100% yamandla ahlaziyekayo enemihla eqala ngo-2015 ukuya ku-2050.
Siza kubona izixeko ezininzi:
Izixeko eziphezulu
1.Copenhagen, nethamsanqa lomoya waselunxwemeni
ICopenhagen, idolophu elikomkhulu laseDenmark, inenzuzo ekhethekileyo kuba ilizwe liphela sele lizibophelele kwiinjongo zamandla ahlaziyekayo ngaphambili. Ngapha koko, Isixeko sisithembiso sokuba sisixeko sokuqala esingathath'icala malunga nokukhutshwa kwekhabhoni ngowama-2025 kube lula kuba imimoya yamanxweme Sele behlangabezana nenxalenye enkulu yeemfuno zamandla esixeko
2. EMunich, ikomkhulu laseBavaria:
Ngabemi abazizigidi eziyi-1,35, EMunich Yidolophu yesithathu ngobukhulu eJamani kwaye yenye yezona ndawo zibalulekileyo kwezoqoqosho elizweni. Ngo-2009, isixeko sabeka umngeni wokuqinisekisa ukuba ngo-2025 unikezelo lwamandla esixekweni luvela kwimithombo evuselelekayo eyi-100%.
Ngokusebenzisana nenkampani eluncedo yesixeko, IStadtwerke iMünchen (I-SWM), ziye zenziwa zasebenza ngenjongo Veza ngokwaneleyo kwizityalo zakho Umbane oluhlaza ukuze ngo-2025 ahlangabezane neemfuno zamandla zommandla oquka iMunich, eqikelelwa ukuba yi-7.500 yezigidigidi ze-KWh ngonyaka.
3. I-Aspen, iColorado: iSki Mecca
Esi sixeko, esikwiphondo laseColorado, eUnited States, kwaye singqongwe ziintaba, sidume ngokuba yenye yezona ndawo zintle kakhulu ukuskiya. Kwakufutshane nje emva kokusekwa kwayo, yaba sisixeko sokuqala eMelika eNtshona ukusebenzisa amandla ombane. Sithetha ngonyaka ka-1885. Idolophu kunye nabemi bayo baqhubeka nesiko kwiminyaka eli-130 kamva ukuba, ngonyaka ka-2015, izixeko zokuqala emhlabeni ukusebenzisa amandla ahlaziyekayo ukwenza i-100% yenkqubo yombane wayo.
4. ISan Diego, eCalifornia:
ICalifornia sele ibonile ukukhula okuqhubekekayo kuzo zombini amandla elanga Njengakwimarike yemoto yombane. E-San Diego, oku kukhula kuguqulwe kwaba ngumzamo wokwakha uluntu olusebenzisayo I-100% yamandla ahlaziyekayo ngowama-2035
5. ISydney, eOstreliya: ukunciphisa ukukhutshwa ngama-70% ngowama-2030
E-Australia iibhetri nazo zibekwa, iSydney yenza eli nyathelo likhulu. Okwangoku, bayasebenza ukunciphisa ukukhutshwa okuveliswe yi ifuthe lamaqondo obushushu abanjwe lungcoliseko ngama-70% phakathi kwangoku nango-2030, esinye sezindululo zale dolophu sesokuba isithathu samandla asetyenzisiweyo kubemi sivela kwimithombo enokuphinda ihlaziyeke kwaye isibini kwisibini kwisithathu kwisizukulwana esisebenza ngokugqibeleleyo.
6. IFrankfurt, Jemani: kukhutshwa iizero ze-CO2 ngowama-2050
UFrankfurt ucinga a ekujoliswe kuko ekunciphiseni yokukhutshwa kwekhabhoni. Konke oku kwilizwe elizinikele ngakumbi kuninzi ekunciphiseni i-CO2. Ngelixa iJamani yonke ilandela imigaqo-nkqubo yayo ye-'gigigewende 'okanye yotshintsho lwamandla, iFrankfurt ifuna ukunciphisa ukukhutshwa kwekhabhoni nge-100% ngo-2050 kutshanje. Sele ikhona ifayile ye- inkqubela phambili ebalulekileyo ekunciphiseni yokusetyenziswa kwamandla, ngaphandle kokukhula kwezoqoqosho kwesi sixeko: IFrankfurt iseke enye ye-arhente yamandla kamasipala kunye ne-arhente yokukhusela imozulu, ebikhuthaza inkqubo ebanzi yolawulo lwamandla ukusukela ngo-1985.
7. ISan José, California: Umbane ovela kuMandla aVuselelekayo ngowama-2022
Ukuba sentlanjeni yeSilicon Valley, iSan José ineenjongo zokuba isebenzise umbane oveliswe ngamandla ahlaziyekayo ngo-2022. Ukwenza oko kwenzeke, isixeko sithathe isigqibo sokunciphisa i-red tape ehambelana nokufaka kunye nokusebenzisa amandla elanga. Ngapha koko, yenye ye zimbalwa izixeko elizweni ephelise isidingo semvume yokwakha xa usongeza iipaneli zelanga kuphahla, isusa olunye ukhuselo olukhulu xa usebenzisa amandla elanga. Phakathi kwabo nabo cwangcisa ukufaka amandla elanga kumaziko kamasipala, axhase itekhnoloji entsha kwaye ancede ekudaleni izivumelwano zokuthenga amandla amakhulu.
Ezi zixeko zizodwa sele zivelise uluhlu olunomtsalane kwaye xa zizonke zimele izigidi kunye nezigidi zabantu, abanobume bendalo obuya kuncitshiswa njengoko behlangabezana neenjongo zabo.
