1.Isidingo samandla emhlabeni wonke sikhula kancane kancane
Ngo-2020, isidingo segesi yemvelo sizokwehla ngo-1.9%.Lokhu ngokwengxenye kungenxa yoshintsho ekusetshenzisweni kwamandla phakathi nenkathi yomonakalo omkhulu kakhulu odalwe ubhubhane olusha.Kodwa ngesikhathi esifanayo, lokhu futhi kuwumphumela wobusika obufudumele enyakatho nenkabazwe ngonyaka odlule.
Ekubuyekezweni kwayo kweGlobal Gas Security Review, i-International Energy Agency (IEA) ithe isidingo segesi yemvelo singase siphinde sikhuphuke ngo-3.6% ngo-2021. Uma kungabhekwa, ngo-2024, ukusetshenziswa kwegesi yemvelo emhlabeni wonke kungase kwenyuke ngo-7% kusukela ezingeni langaphambi kwalolu bhubhane olusha.
Nakuba uguquko olusuka emalahleni luye kugesi yemvelo lusaqhubeka, ukukhula kwesidingo segesi yemvelo kulindeleke ukuthi kunciphe.I-International Energy Agency yathi ohulumeni bangase badinge ukwenza umthetho ukuze baqinisekise ukuthi ukukhula kwesisi esikhiswayo esihlobene negesi yemvelo ngeke kube inkinga - sidinga izinqubomgomo ezifisa kakhulu ukuze sidlulele emgomweni “wokungakhiqizi ngokuphelele kwegesi”.
Ngo-2011, amanani egesi yemvelo eYurophu akhuphuke ngo-600%.Kusukela ngo-2022 kuze kube manje, uchungechunge lokusabela okubangelwa ukungqubuzana phakathi kweRussia ne-Ukraine nakho kuye kwaholela ngokuqondile ekuswelekeni okukhulu kwamandla omhlaba, futhi ukuhlinzekwa kukawoyela, igesi yemvelo kanye nogesi kuthinteke kakhulu.
ENyakatho Nenkabazwe, ekuqaleni kuka-2021 kuphazanyiswa uchungechunge lwezehlakalo zesimo sezulu esibanda kakhulu.Izindawo ezinkulu zase-United States zithintwa i-polar vortex, eletha iqhwa, iqhwa namazinga okushisa aphansi esifundeni esiseningizimu yeTexas.Obunye ubusika obubanda kakhulu enyakatho nenkabazwe buzofaka ingcindezi eyengeziwe ohlelweni oluvele lunwetshiwe lokunikezwa kwegesi yemvelo.
Ukuze ubhekane nesidingo samandla esikhulayo esimweni sezulu esibandayo, akudingekile kuphela ukuxazulula izinselele ezilethwa i-inventory yegesi yemvelo ephansi.Ukuqasha imikhumbi ezothutha i-LNG emhlabeni wonke kuzophinde kuthikamezeke umthamo onganele wokuthutha, okwenza kube nzima futhi kubize ukubhekana nokwanda kwesidingo samandla.I-International Energy Agency ithe, “Ebusika obuthathu obusenyakatho nenkabazwe, imali yokuqasha umkhumbi i-LNG nsuku zonke ikhuphuke yafinyelela ngaphezu kwamadola ayi-100000.Emakhazeni abengalindelekile eNyakatho-mpumalanga ye-Asia ngoJanuwari 2021, esimweni sokushoda kwangempela kwamandla okuthutha atholakalayo, imali yokuqasha umkhumbi isifinyelele emlandweni ophezulu wamadola angaphezu kuka-200000.”
Bese-ke, ebusika bango-2022, singawugwema kanjani umthelela empilweni yethu yansuku zonke ngenxa yokushoda kwezinsiza?Lona umbuzo okufanele ucatshangelwe
2.Amandla ahlobene nempilo yethu yansuku zonke
Amandla asho izinsiza ezinganikeza amandla.Amandla lapha ngokuvamile asho amandla ashisayo, amandla kagesi, amandla okukhanya, amandla emishini, amandla amakhemikhali, njll. Izinto ezinganikeza amandla e-kinetic, amandla emishini kanye namandla kubantu.
Amandla angahlukaniswa abe izigaba ezintathu ngokwemithombo: (1) Amandla avela elangeni.Kuhlanganisa amandla aphuma ngqo elangeni (njengamandla emisebe yelanga eshisayo) kanye namandla angaqondile avela elangeni (njengamalahle, uwoyela, igesi yemvelo, i-oil shale namanye amaminerali avuthayo kanye namandla e-biomass afana nezinkuni zokubasa, amandla amanzi kanye amandla omoya).(2) Amandla avela emhlabeni ngokwawo.Enye igeothermal equkethwe emhlabeni, njengamanzi ashisayo angaphansi komhlaba, isitimu esingaphansi komhlaba kanye nenqwaba yamadwala ashisayo;Okunye amandla enuzi e-athomu aqukethwe kumafutha enuzi njenge-uranium ne-thorium engaphansi komhlaba.(3) Amandla akhiqizwa amandla adonsela phansi ezinto ezisemkhathini njengenyanga nelanga emhlabeni, njengamandla olwandle.
Njengamanje, uwoyela, igesi yemvelo kanye nezinye izinsiza zamandla ziyashoda.Singacabangela amandla esizowasebenzisa?Impendulo ithi yebo.Njengomgogodla wesimiso sonozungezilanga, ilanga liletha amandla amakhulu emhlabeni nsuku zonke.Ngokuthuthuka kwesayensi nobuchwepheshe bethu, izinga lokusebenzisa amandla elanga liyathuthuka kancane kancane, futhi selithuthuke laba ubuchwepheshe obungathola amandla ngezindleko eziphansi.Umgomo walobu buchwepheshe ukusebenzisa amaphaneli elanga ukuze uthole amandla emisebe yelanga eshisayo futhi uwaguqule abe yisitoreji samandla kagesi.Njengamanje, isixazululo esingabizi kakhulu esitholakalayo semindeni yiphaneli yebhethri+ibhethri lasendlini eligcina amandla/ibhethri langaphandle lokugcina amandla.
Ngingathanda ukunikeza isibonelo lapha ukuze ngikusize uqonde kangcono lo mkhiqizo.
Othile wangibuza, ungakanani ugesi ongakhiqiza amandla elanga angama-watt ayi-100 ngosuku?
100 W * 4 h=400 W h=0.4 kW h (kWh)
Ibhethri elilodwa elingu-12V100Ah=12V * 100AH=1200Wh
Ngakho-ke, uma ufuna ukushaja ngokugcwele ibhethri elingu-12V100AH, udinga ukulishaja ngokuqhubekayo ngamandla elanga angu-300W amahora angu-4.
Ngokuvamile, ibhethri lingu-12V 100Ah, ngakho ibhethri elishajiwe ngokugcwele futhi elingasetshenziswa ngokujwayelekile lingakhipha i-12V x 100Ah x 80%=960Wh
Uma usebenzisa izinto zikagesi ezingu-300W, ngokwethiyori 960Wh/300W=3.2h, ingasetshenziswa amahora angu-3.2.Ngokufanayo, ibhethri le-24V 100Ah lingasetshenziswa amahora angu-6.4.
Ngamanye amazwi.Ibhethri engu-100ah idinga kuphela ukusebenzisa iphaneli yelanga ukushaja amahora angu-4 ukuze inike amandla iheater yakho encane amahora angu-3.2.
Okubaluleke kakhulu ukuthi lokhu ukucushwa okuphansi kakhulu emakethe.Kuthiwani uma siyishintsha sifake iphaneli yebhethri enkulu nebhethri elikhudlwana lokugcina amandla?Uma siwashintsha sifaka amabhethri amakhulu okugcina amandla namaphaneli elanga, sikholwa ukuthi angasinika izidingo zansuku zonke zasekhaya.
Isibonelo, ibhethri yethu yokugcina amandla i-FP-F2000 yakhelwe ukuhamba ngaphandle, ngakho-ke iphatheka kalula futhi ilula.Ibhethri linomthamo ongu-2200Wh.Uma kusetshenziswa into engu-300w, ingasetshenziswa ngokuqhubekayo amahora angu-7.3.
