Kuyo yonke iplanethi, izinto ezinokuhlaziywa zithatha ukubaluleka ngakumbi nangakumbi. Ukulungiselela inani lobungakanani bamandla eveliswa kumandla ahlaziyekayo, i I-Arhente yaMandla yaMazwe ngaMazwe (IEA) wenze ibhalansi yonyaka ka-2016. Le ntsalela ibala inani elipheleleyo lamandla elanga e-photovoltaic aveliswayo kwihlabathi liphela.
Esinye seziphumo zokulinganisela kukuba ngo-2016 i-75 gigawatts epheleleyo yongezwa kwipaki ye-photovoltaic jikelele. Ngawaphi amazwe anegalelo ekufumaneni elona nani likhulu lamandla elanga emhlabeni?
Ukonyuka kokuveliswa kwamandla elanga kwe-photovoltaic
Phakathi kwamazwe ongeze amandla ngakumbi ekuvelisweni kombane sifumana iSweden neFrance. Nangona kunjalo, nangona ingeyonto intsha okwangoku, iSpain yongeze kuphela iimegawatts ezingama-55 kwipaki yayo yesizwe ngo-2016. Ukufikelela kumazwe ayi-16 ongeze ngaphezulu kwe-500 megawatts.
Ukukhula kwezinto ezivuselelekayo kwinqanaba lehlabathi sele kubaluleke kakhulu. Ngunyaka wokuqala apho iigigawatts ezingama-300 zidlulisiwe kwiplanethi iphela. Ngo-2016, inani lilonke lenyuswe ngama-gigawatts angama-75 ahlulwe aba: I-China (ine-34,5), i-United States (ine-14,7), iJapan (nge-8,6) kunye ne-India (4). La ngawamazwe afake amandla ahlaziyekayo. ISpain ibenegalelo kuphela kunyuso lwe0,05 GW.
Ingxelo yenza ukuba amazwe afana neJapan neYurophu ngokubanzi, anyuse amandla abo anokuphinda ahlaziyeke kancinci xa kuthelekiswa no-2015. Nangona kunjalo, ibonisa ukuba inkqubela phambili yezinto ezinokuhlaziywa kumgangatho wehlabathi ugcwele ngokupheleleyo. Oku kubalulekile kwikamva lezamandla, uphuhliso oluzinzileyo olunceda ekupheliseni ukuxhomekeka kumafutha asefosili kunye negalelo kumlo ochasene notshintsho lwemozulu.
Ulindelo olukhulu kutyalo-mali lunokuvelisa ukuwa, njengaleyo kaZapatero kunye neenkxaso-mali zakhe, ezinyanzele abokuqala ukuba bachithe imali bayokutshona ngenxa yokuzithemba ngokugqithisileyo kwaye bakhuthazwe yinkxaso-mali yokwenza izihlangu apho kungurhulumente okanye abangalumkanga ndatyala imali kwizihlangu zesithunzi, xa itekhnoloji yayingavuthwanga ngokupheleleyo. I-Zapateril kufuneka ibe yinto yokufunda kwiiyunivesithi, kwezopolitiko nakwezoqoqosho, malunga nendlela izinto ezingenakwenziwa kwaye ekungafuneki zenziwe, kwaye ingalahli incwadi yokutshekisha njengezityebi ezitsha, ngapha koko iyisoshiyali, ayazi ukuchitha okanye Utyalo-mali, ukholelwa ekubeni uRhulumente usombulula yonke into kwaye uRhulumente akasebenzi, urhulumente akakho, akanguye onamandla onke, uRhulumente yinto ehlawulwa ngabemi ngerhafu yakhe kwaye enomda, amandla emveliso, imveliso urhulumente Ayijongeki kunye nolwakhiwo lwayo lwenkonzo yoluntu, isabelo esibi semithombo yobutyebi.Ukuba akunjalo, cela izinto ezinokuphinda zisebenze kunye nokungabinamali kwemodeli yezihlangu ezingachaphazeli kuphela ekhohlo.
