El kuwedzera mumatekinoroji uye kusimudzira kwesimba rinowedzerwazve Ivo vanotiita isu, zvishoma nezvishoma, vanovimba zvishoma nefossil fuels mumatunhu mazhinji eindasitiri nebasa. Ndokusaka kushandiswa kwemafuta emafuta kuri kudzikiswa munyika zhinji nekuda kwekushandiswa kwesimba rakachena.
Nekuda kweiyi nhanho iri kuramba ichikura, iyo International Energy Agency (IEA) inofanotaura kuderera kwemakore mashanu anotevera mukuda kwepasi kwemarasha. Kunyanya, inyika dzeAsia dzinoshandisa marasha kuita mafuta uye kugadzira magetsi. Mumakore anotevera, kudzikira kwekushandisa marasha kunotarisirwa munyika dzeAsia.
Kunyangwe paine chokwadi chekuti marasha mashoma uye mashoma ari kudyiwa kutenderera pasirese, mashandisirwo awo achiri asingadzivisike Nyika inoenderana nemarasha. IEA inotaura mugwaro reBeijing kuti shanduko uye mashandisiro emarasha zvinoenderana nezvinodiwa kubva kuChina. Nhasi China inodya 50% yekabhoni yepasi rose uye ingangoita hafu yezvose zvigadzirwa. Chaunowana semhedzisiro ndiwo maguta makuru akasvibiswa nekushandisa zvakanyanya kwemarasha.
Izvo zvikonzero zvikuru zvekudzikira mukushandiswa kwemarasha muChina neUnited States zvinokonzerwa nekuwedzera kwesimba kwemagetsi pamwe nekuvandudzwa kwesimba rinowedzerwazve. Kwenguva yekutanga muzana rino ramakore, kudiwa kwemarasha kwakadonha muna 2015. Kune rimwe divi, Europe neNorth America vanodya hafu yemarasha yakawanda sa2000. Nekudaro, kushandiswa kwemarasha kwakawedzera kuita account yezvikamu zvitatu zvekota zvekudyiwa kwepasirese muna 2015 uye, sekureva kweIEA, maitiro aya akawedzera.
Chekupedzisira, nhasi, marasha ane basa 45% yezvese zvepasi rose carbon dioxide inoburitsa izvo zvinokonzeresa iyo greenhouse mhedzisiro, asi inokwezva kune nyika sezvo iri isingadhuri uye yakawanda mineral.
