Ukujongana nokutshintsha kwemozulu, uluntu kuya kufuneka lwembe nzulu.
Nangona umphezulu weplanethi yethu usikelelwe ngonikezelo olungapheliyo lwelanga kunye nomoya, kufuneka sakhe iipaneli zelanga kunye nee turbines zomoya ukuze sisebenzise onke loo mandla - singasathethi ke ngeebhetri zokuwagcina.Oko kuya kufuna izixa ezikhulu zezinto ezikrwada eziphuma ngaphantsi komhlaba.Okubi nakakhulu, ubugcisa obuluhlaza buxhomekeke kwiiminerali ezithile eziphambili ezihlala zinqongophele, zigxininiswe kumazwe ambalwa kwaye kunzima ukuzikhupha.
Esi ayisosizathu sokubambelela kumafutha amdaka amdaka.Kodwa bambalwa abantu abaziqondayo iimfuno ezinkulu zemithombo yamandla ahlaziyekayo.Ingxelo yakutshanje evela kwi-International Energy Agency yalumkisa ngelithi: “Ukutshintshela kumandla acocekileyo kuthetha ukushenxiswa kwindlela etya amafutha amaninzi ukuya kweyokusebenzisa izinto eziphathekayo.”
Qwalasela iimfuno zeeminerali ezisezantsi zamafutha efosili enekhabhoni ephezulu.Isixhobo samandla segesi yendalo esine-megawatt enye yomthamo-okwaneleyo ukunika amandla phezu kwamakhaya angama-800-kuthatha malunga ne-1,000 kg yeeminerali ukwakha.Kwisityalo samalahle esilingana ngobukhulu, simalunga nama-2,500 kg.I-megawatt yamandla elanga, ngokuthelekisa, ifuna phantse i-7,000 kg yeeminerali, ngelixa umoya ovela ngaphandle kolwandle usebenzisa ngaphezu kwe-15,000 kg.Gcina ukhumbula, ukukhanya kwelanga kunye nomoya azihlali zikhona, ngoko ke kufuneka wakhe iipaneli zelanga ezingaphezulu kunye neeinjini zomoya ukuze uvelise umbane wonyaka ofanayo njengeplanti yefosili.
Umahluko uyafana kwezothutho.Imoto enegesi eqhelekileyo iqulethe malunga ne-35 kg yesinyithi esinqabileyo, ubukhulu becala ubhedu kunye nemanganese.Iimoto zombane azidingi nje ukuphinda kabini inani lezo zinto zimbini, kodwa kunye nobuninzi be-lithium, i-nickel, i-cobalt kunye ne-graphite - ngaphezu kwe-200 kg iyonke.(Amanani apha kunye nomhlathi odlulileyo awubandakanyi amagalelo amakhulu, intsimbi kunye ne-aluminium, kuba zizinto eziqhelekileyo, nangona zivelisa i-carbon-intensive ukuvelisa.)
Lilonke, ngokwe-International Energy Agency, ukufikelela kwiinjongo zemozulu yaseParis kuya kuthetha ukuphinda-phindwe kane kokunikezelwa kwezimbiwa ngowama-2040. Ezinye izinto kuya kufuneka zinyuke nangakumbi.Ihlabathi liya kufuna amaxesha angama-21 njengoko lidla ngoku kunye namaxesha angama-42 kwi-lithium.
Ngoko ke kufuneka kubekho iinzame zehlabathi zokuphuhlisa imigodi emitsha kwiindawo ezintsha.Nkqu nomgangatho wolwandle awunakuthintelwa.Abagcini bendalo esingqongileyo, banexhala lokwenzakala kwi-ikhosistim, bayayiphikisa, kwaye ngokwenene, kufuneka senze zonke iinzame zokumba umgodi ngokuthembekileyo.Kodwa ekugqibeleni, kufuneka siqonde ukuba utshintsho lwemozulu yeyona ngxaki inkulu yendalo yexesha lethu.Isixa esithile somonakalo owenziwe kwindawo lixabiso elamkelekileyo lokuhlawula ukusindisa iplanethi.
Ixesha libalulekile.Nje ukuba iidipozithi zezimbiwa zifunyenwe kwenye indawo, azikwazi nokuqalisa ukuphuma emhlabeni de kube semva kocwangciso olude, imvume kunye nenkqubo yokwakha.Ngokuqhelekileyo kuthatha iminyaka engaphezu kwe-15.
Kukho iindlela esinokulususa ngazo uxinzelelo ekufumaneni izinto ezintsha.Enye kukuhlaziya kwakhona.Kule minyaka ilishumi izayo, ukuya kuthi ga kwi-20% yeentsimbi zeebhetri zeemoto zombane ezintsha zinokuhlangulwa kwiibhetri ezichithiweyo kunye nezinye izinto ezifana nemathiriyeli yokwakha endala kunye nee-elektroniki ezilahliweyo.
Kufuneka kwakhona sityale imali kuphando ukuphuhlisa itekhnoloji exhomekeke kwizinto eziyintabalala.Ekuqaleni kwalo nyaka, kwakukho ukuphumelela okubonakalayo ekudaleni ibhetri yomoya wentsimbi, eya kuba lula kakhulu ukuvelisa ngaphezu kweebhetri ze-lithium-ion ezikhoyo.Itekhnoloji enjalo iseyindlela, kodwa luhlobo kanye lwento enokuthintela ingxaki yezimbiwa.
Ekugqibeleni, esi sisikhumbuzo sokuba konke ukusetyenziswa kuneendleko.Yonke i-ounce yamandla esiyisebenzisayo kufuneka ivele kwindawo ethile.Kulungile ukuba izibane zakho zisebenza kumandla omoya endaweni yamalahle, kodwa oko kusathatha izibonelelo.Ukusebenza kwamandla kunye nokutshintsha ukuziphatha kunokunciphisa ubunzima.Ukuba utshintsha iiglowubhu zakho ze-incandescent ukuya kwii-LED kwaye ucime izibane zakho xa ungazidingi, uya kusebenzisa umbane omncinci kwasekuqaleni kwaye ngoko ke izinto ezikrwada zibe mbalwa.
