Mu bijyanye no kurengera ibidukikije, icyi kinyejana gishya kigaragaramo ingorane zituruka ku mwanda ujya mu kirere, ingaruka mbi z’imihindagurikire ry’ibihe, hamwe n’ubushyuhe bukabije bw’isi. Bimwe mu bihugu byagaragaye ko byohereza imyuka myinshi yangiza ikirere, usanga bifite inganda zikomeye ndetse bikaba n’ibihugu bifite umubare munini w’abaturage. Dore urutonde rw’ibihugu 10 biza ku isonga mu kwanduza ikirere:
1. Ubushinwa: Ni cyo gihugu kiza imbere mu kwanduza ikirere ku isi. Ubushinwa bufite inganda nyinshi zikora ibintu bitandukanye ndetse n’ingufu nyinshi zituruka ku makara, bikaba intandaro yo kwanduza ikirere ku gipimo cyo hejuru.
2. Amerika: Kuba igihugu gikomeye mu bukungu, bifite ingaruka zikomeye ku mwuka wangiza ikirere kubera inganda nyinshi, imodoka nyinshi, hamwe n’ikoreshwa rikabije ry’amakara n’ibikomoka kuri peteroli.
3. Ubuhinde* Bufite umubare munini w’abaturage kandi bufite n’inganda nyinshi zikoresha amakara nk’inkomoko y’ingufu, bituma buza mu bihugu byohereza imyuka myinshi yangiza ikirere.
4. Uburusiya: Bufite inganda nyinshi ndetse n’ikoreshwa rikabije ry’amakara n’ibindi bikomoka kuri peteroli mu gutanga ingufu. Ubucukuzi bw’ibikomoka kuri peteroli nabwo bugira uruhare mu kwanduza ikirere.
5. Ubuyapani: Bufite inganda zikomeye zitanga imyuka myinshi yangiza ikirere, kandi kuba igihugu giteye imbere mu ikoranabuhanga bituma gikoresha ingufu nyinshi zituruka ku bikomoka kuri peteroli n’amakara.
6. Ububiligi: Bufite inganda nyinshi cyane zikoreshwa mu gutunganya ibintu bitandukanye, kandi bufite imodoka nyinshi zikoreshwa cyane, bigira uruhare mu kwanduza ikirere.
7. Ubudage: Bufite inganda nyinshi zikora imodoka, ibyuma, n’ibindi bikoresho. Ubudage bukunze gukoresha amakara n’ibikomoka kuri peteroli mu gutanga ingufu.
8. Uburusiya: Bufite inganda nyinshi zikora ku buryo bw’imyuka myinshi yoherezwa mu kirere, bikaba intandaro yo kwangiza ikirere.
9. Ubwongereza: Bufite inganda nyinshi ndetse n’ikoreshwa rikabije ry’imodoka n’amakara mu gutanga ingufu, bigira uruhare mu kwanduza ikirere.
10. Canada: Nubwo ifite umubare muto w’abaturage ugereranije n’ubuso bwayo, Canada ifite inganda zikomeye kandi ikoresha ingufu nyinshi zituruka ku bikomoka kuri peteroli n’amakara.
Ibihugu byinshi bikora uko bishoboye ngo bigabanye imyuka yanduza ikirere binyuze mu gukoresha ingufu zisubira (renewable energy), gushyira mu bikorwa amategeko arengera ibidukikije, no gushishikariza abaturage gukora ibikorwa bitangiza ikirere. Ariko urugendo ruracyari rurerure kugira ngo tugere ku rwego rwo kurengera ikirere ku buryo burambye.
