Inkinga yokuphila kwemvelo kanye nokusetshenziswa kwemithombo yemvelo iyaba yingozi nakakhulu. Amazwe amaningi awafuni ukusebenzisa imvelo yemithombo yamandla - umoya, ilanga namanzi amandla, kodwa bakhetha ukuqhubeka nokukhipha imithombo yemvelo.
Kodwa, ngenhlanhla, amazwe amaningi athuthukile ayaqonda ukuthi ukutshala izimali eziphilayo ezihlanzekile kuyisinyathelo esikhulu ekuvikeleni imvelo nokushintsha umhlaba ukuze ube ngcono. La maqiniso angu-25 mayelana nokusetshenziswa kwamandla ahlanzekile azosiza ukuqonda ukuthi akuwona konke okungahle kube nethemba njengoba sicabanga.
1. Ukubona inzuzo yokusebenzisa imithombo yamandla yemvelo, izinkampani ezinkulu ezifana neWalmart neMicrosoft ziye zatshala ingxenye ebalulekile yalezi zimali ekukhiqizeni amabhethri emandla elanga nelomoya.
Izinhloko zezinkampani zithemba ukuthi esikhathini esizayo lokhu kuzosiza ukuthi kunganciki emithonjeni yamanzi.
2. I-European Union, ngaphandle kwePoland neGreece, ithi ngonyaka ka-2020 kuzophela ukwakhiwa kwazo zonke izitshalo zamalahle.
Isitatimende esingalindelekile sithole ukwesekwa okukhulu nokuvunywa kusuka ekuhambeni okuhlukahlukene kwemvelo.
3. Ama-wind turbines asezingeni eliphezulu anamandla okuhlinzeka amandla ngamakhaya angu-300.
Futhi le mpumelelo, engakwazi ukuziqhenya ngempela. Futhi maduzane, inkampani yaseJalimane yakha ama-turbines anganikeza amandla emakhaya angu-4 000! Ngicabanga ukuthi abanikazi baseJalimane bazoqhubeka yini.
4. Ukusetshenziswa kwamapaneli enelanga esikhathini sethu kuyindlela ephumelela kakhulu futhi ebiza imali yokuvikela imvelo.
Amandla we-solar esikhathini sethu asho ukuthi ungumthombo omkhulu wamandla esikhathini esizayo esiseduze.
5. Ngokusho kocwaningo lweWorld Wildlife Fund, ngo-2050, amandla ahlanzekile azokwazi ukuhlangabezana nezidingo zamandla emhlabeni jikelele ezingaphezu kwezingu-95%.
6. Muva nje, uhlelo lokushintsha izimoto zamabhayisikili lukhule kakhulu emhlabeni wonke. Uhlelo lusebenza emadolobheni angaphezu kuka-800 emazweni angu-56.
7. Ngokukhula kokuthandwa kwamandla ahlanzekile, uhlelo lokuthuthukiswa kwamandla enyukliya kusukela ngo-2006 kuya ku-2014 wehle ngo-14% ngenxa yezindleko eziphakeme, kanye nezizathu zokuphepha.
8. Uma sisebenzise ngokugcwele ilanga, khona-ke ihora elilodwa elinelanga lingakwanela ukuqinisekisa ukuthi umhlaba wonke uthola amandla unyaka wonke.
9. IPortugal isenze intuthuko enkulu emkhakheni wamandla ahlanzekile.
Eminyakeni emihlanu, bakhulisa ukusetshenziswa kwemithombo evuselelwe amandla esuka ku-15 kuya ku-45%, okufakazela ukuthi wonke amazwe angakwenza ngesikhathi esifushane.
Amandla ahlanzekile yindlela enhle kakhulu yokudala imisebenzi eyengeziwe.
Ngokusho kombiko we-Environmental Protection Fund, imithombo yamandla evuselelekayo yashiya lonke umnotho wase-US ekudaleni imisebenzi ngo-12%.
11. I-China inesithakazelo esikhulu ekuvikeleni imvelo. Kusukela ngo-2014, i-China ikhiphe ama-turbine angu-2 ngosuku.
12. EWest Virginia, bahlela ukushiya izimayini zamalahle futhi bagxile emandleni okushisa.
Ngokwesifundo se-Southern Methodist University, iWest Virginia ingahlinzeka amandla omzimba wabantu, isebenzisa kuphela u-2% wamandla kagesi.
13. Esikhathini sethu, ukugcina amanzi ahlanzekile kubaluleke kunanini ngaphambili.
Ngenhlanhla, uma usebenzisa amandla ahlanzekile elanga nelanga, udinga amanzi amancane. Esikhathini sokuqala - 99 amalitha amanzi, okwesibili - zero. Uma kuqhathaniswa, imithombo yamanzi idinga ukusebenzisa amalitha angu-2600 amanzi.
14. IBrithani enkulu ngo-2016 yathola impumelelo enkulu kule ndlela. Ama-50% wamandla avela emithonjeni evuselelekayo nephansi-carbon.
Amandla ahlanzekile asisiza ukuqeda isidingo sokuthola imithombo yamapetroli, eyenza ukusimama komnotho, kusiza ukugcina intengo yamafutha.
16. Ngokuphathelene neziphepho nezinye izenzakalo ezonakalisayo eziba zivame kakhulu, amandla ahlanzekile umthombo ozinzile kunamalahle, njengoba usatshalaliswa ngendlela efanayo futhi unamamodeli we-modular.
Izimoto zikagesi zinamathuba amaningi, kufaka phakathi umoya ohlanzekile, ukuxhomekeka kancane ezintweni zezinto eziphilayo kanye nokukwazi ukuyilayisha kabusha ekhaya noma eziteshini zamandla elanga.
18. Ucwaningo olwenziwa yiHarvard University lathola ukuthi umonakalo wamalahle ezempilo yabantu ubiza amaRandi angama-74.6 billion. Ngenxa yamandla ahlanzekile, angabonakali ukungcola, lezi zintengo zinganciphisa kakhulu.
19. Amafutha asetshenzisiwe awanakuvuselelwa, futhi lokhu kungaholela ekukhokheni kwabo okuphezulu. I-Net energy ayinasiphelo, okusho ukuthi izindleko zayo zizinzile futhi akudingeki sikhathazeke ngokuntuleka kwayo.
20. Isitshalo esikhulu kunazo zonke esitshalo se-solar se-Mojave Desert emahektare angu-3 500 wezwe futhi singabakwazinkampani ezifana ne-NRG Solar, i-Google ne-Bright Star Energy.
21. I-hydroelectric plant plant nayo ingumthombo omuhle wamandla ahlanzekile. E-USA kuphela ngo-2004, ngenxa yemithombo yamanzi, kwakungagwenywe amathani ayizigidi ezingu-160 ezikhishwe kaboni.
22. Ngo-2013, insimu enkulu kunazo zonke emhlabeni jikelele e-London Array, epulazini laseKent nase-Essex eNtshonalanga yaseThames, engamakhilomitha angu-20 ukusuka ogwini, yaqala ukusebenza.
23. Amandla ahlanzekile angatholakali kuphela umoya noma ilanga. I-Siemens isungule isitshalo sokuqala ukuguqula i-biogas kusuka kwezitshalo zokuhlanza ugesi ukuze isebenze amaseva ayo.
24. Abacwaningi eYunivesithi yaseTokyo ngo-2015 bahlela ukusebenzisa ingxenye yezindawo eziqothulwa emhlabeni ukuze banikeze ingxenye yesihlabathi. Ubuza kanjani? Ukuguqula isiconsi kusuka esihlabathini kuze kube ugesi.
25. Kuzo zonke izinhlobo zemithombo yemvelo emhlabeni, izilwandle zisetshenziswa kancane, kepha zingasiza.
Njengamanje, ososayensi abaningi bakholelwa ukuthi lapho kudala ubuchwepheshe obusha kakhulu ukuthola amandla emanzini, kuzokwazi ukuhlinzeka ugesi ezingaphezu kuka-3 billion zabantu bomhlaba.
Nazi amaqiniso anjabulo nenethemba elivela emhlabeni jikelele. Sithemba ukuthi lo mkhuba uzokwanda njalo ngonyaka hhayi amazwe kuphela, kepha umhlaba wonke uzoqonda izinzuzo zokusebenzisa imithombo yamandla ahlanzekile.
