Kuti vagadzirise kushanduka kwemamiriro ekunze, vanhu vachada kuchera zvakadzika.
Kunyangwe nzvimbo yepasi redu yakakomborerwa nekupihwa kwezuva nemhepo kusingaperi, isu tinofanirwa kuvaka ma solar panels nematurbines emhepo kuti tishandise simba rose iroro - tisingarevi mabhatiri ekuichengeta.Ikoko kuchada zvitsama zvikuru zvezvinhu zvakabikwa zviri pasi pevhu.Zvakatoipa, matekinoroji egirinhi anovimba nemamwe mamineral akakosha anowanzo kushomeka, akaiswa munyika shoma uye zvakaoma kuburitsa.
Ichi hachisi chikonzero chekunamatira kune tsvina yefossil fuels.Asi vanhu vashoma vanoziva kukosha kwezviwanikwa zvesimba rinogonekazve.Mumwe mushumo wenguva pfupi yapfuura wakabva kuInternational Energy Agency wakanyevera kuti: “Kuchinja kune simba rakachena kunoreva kuchinja kubva pakushandisa mafuta akawanda kuenda kukushandisa zvinhu zvakawanda.”
Funga nezve yakaderera-mineral zvinodiwa zvepamusoro-kabhoni fossil mafuta.Chigadzirwa chemagetsi egasi chine megawati imwe chete yesimba - inokwana simba pamusoro pedzimba mazana masere - inotora 1,000 kg yemamineral kuvaka.Kune marasha chirimwa chehukuru hwakafanana, inenge 2,500 kg.Megawati yesimba rezuva, kana tichienzanisa, inoda inenge 7,000 kg yemaminerari, nepo mhepo yekumhiri kwegungwa inoshandisa zvinopfuura 15,000 kg.Ramba uchifunga, kupenya kwezuva nemhepo hazviwanzo kuwanikwa, saka unofanirwa kuvaka mamwe mapaneru ezuva uye ma turbines emhepo kuti agadzire magetsi epagore mamwe chete sechigadzirwa chemafuta.
Kusiyana kwakafanana mune zvekufambisa.Mota inofambiswa negasi inokwana makirogiramu makumi matatu neshanu emasimbi anoshomeka, kunyanya mhangura nemanganese.Motokari dzemagetsi hadzingodi zvakapetwa kaviri huwandu hwezvinhu zviviri izvi, asiwo yakawanda yelithium, nickel, cobalt uye graphite - inopfuura 200 kg muhuwandu.(Nhamba dziri pano uye mundima yapfuura hazvibatanidzi zvakakurisa, simbi nearuminiyamu, nekuti zvinhu zvakajairika, kunyangwe zvine kabhoni kugadzira.)
Zvose pamwe chete, maererano neInternational Energy Agency, kubudirira kwezvinangwa zveParis pamamiriro ekunze kuchareva kuwanda kwezvicherwa zvakapetwa kana panosvika 2040. Zvimwe zvinhu zvichatowedzera kukwira.Nyika ichada zvakapetwa ka21 pane zvairi kushandisa iye zvino uye ka42 mu lithium.
Saka panofanirwa kuve nekuedza kwepasi rose kugadzira migodhi mitsva munzvimbo itsva.Kunyange pasi pegungwa haigoni kuvharwa.Vezvemamiriro ekunze, vanonetsekana nezve kukuvadza kune ecosystem, chinhu, uye zvechokwadi, isu tinofanirwa kuita kuyedza kwese kuchera zvine hungwaru.Asi pakupedzisira, tinofanira kuziva kuti kuchinja kwemamiriro ekunze ndiro dambudziko guru rezvakatipoteredza renguva yedu.Imwe huwandu hwekukuvadzwa kwenzvimbo mutengo unogamuchirwa kubhadhara kuchengetedza pasi.
Nguva ndiyo inokosha.Kamwe mamineral deposits awanikwa kumwe kunhu, haakwanise kana kutanga kubuda pasi kusvika mushure mekuronga kwenguva refu, kubvumidza uye kuvaka.Zvinowanzotora anopfuura makore gumi nemashanu.
Pane nzira dzatinogona kutora imwe yekumanikidza kutsvaga zvitsva zvekushandisa.Imwe ndeye kudzokorora.Mumakore gumi anotevera, simbi dzinosvika makumi maviri muzana dzemabhatiri emotokari emagetsi matsva dzinogona kubviswa kubva mumabhatiri akashandiswa uye zvimwe zvinhu zvakaita sezvivakwa zvekare uye zvemagetsi zvakaraswa.
Tinofanirawo kuisa mari mukutsvagisa kugadzira matekinoroji anovimba nezvinhu zvakawanda.Pakutanga gore rino, pakava nekubudirira kwakajeka mukugadzira iron-air bhatiri, iyo yaizova nyore kubudisa kupfuura mabhatiri e-lithium-ion aripo.Tekinoroji yakadaro ichiri kure, asi ndiyo chaiyo mhando yechinhu chinogona kudzivirira dambudziko rezvicherwa.
Pakupedzisira, ichi chiyeuchidzo chokuti kushandiswa kwese kune mari.Chese chese chesimba chatinoshandisa chinoda kubva kune imwe nzvimbo.Zvakanaka kana marambi ako achimhanya pasimba remhepo pane marasha, asi izvo zvichiri kutora zviwanikwa.Kushanda kwesimba uye kuchinja kwemaitiro kunogona kuderedza kunetsa.Kana ukachinja magirobhu ako ekuisa maLED uye wodzima mwenje wako pausingaade, unenge washandisa magetsi mashoma uye nekudaro zvinhu zvishoma.
