Niki grid - kubika ingufu zingana?

Muri Gashyantare 2021, nari mpamagaye hamwe n’umukozi ushinzwe kubika muri Texas igihe ibiciro by’amashanyarazi byinshi byageraga ku $ 9,000 kuri megawatt -. Amadolari ibihumbi icyenda. Kubijyanye, ibiciro bisanzwe bizenguruka $ 30 - 50. Sisitemu ye ya batiri yacapaga amafaranga - isohoka muri gride mugihe cyumuyaga Uri mugihe uruganda rwa gaze rusanzwe rwakonje cyane. Ati: "Ibi nibyo twubatsemo", ariko ijwi rye ryari rifite aho rigarukira. Hafi yo kurenganurwa. Nkuko yari ategereje imyaka kugirango yerekane abashidikanya nabi.

Ako kanya - kureba ibiciro byazamutse kuri ecran yubucuruzi mugihe imiyoboro yaturika hirya no hino muri leta - yatomboye ikintu naba narazengurutse igihe gito. Grid - ububiko bwibipimo ntabwo mubyukuri bijyanye nikoranabuhanga. Nibyerekeye niba twiteguye kwemera ko uburyo dukoresha amashanyarazi mumyaka ijana bitagikora.

Reka dusubize inyuma . 2000 na 2001, Californiya yari ifite umwijima. Ntabwo rimwe cyangwa kabiri - inshuro mirongo. Abantu babuze ingufu, amatara yumuhanda yijimye, ibitaro byahinduye moteri. Iperereza ryakozwe ryashinjaga ko isoko rya Enron ryakoreshejwe mu isoko, ibyo bikaba byari ukuri, ariko ntabwo byari inkuru yose. Ikibazo nyacyo cyagenze cyane. Urusobe rwa Californiya rwakozwe hafi yinganda za peteroli ushobora kugenzura. Ukeneye imbaraga nyinshi? Gutwika gaze nyinshi. Ibisabwa biragabanuka? Subiza inyuma. Biroroshye.

Usibye ko byahagaritse kuba byoroshye mugihe ibisekuru bisubirwamo byatangiye bifite akamaro. Kandi sinshaka kuvuga token panneaux yamashanyarazi bimwe byashyizwe kuri PR muri 90. Ubushobozi nyabwo. Gigawatts.

Nari mu nama yabereye i San Diego - igomba kuba yarabaye 2014 cyangwa 2015 - aho injeniyeri ISO wo muri Californiya yerekanye icyo bise "inkongoro y'imbwa." Icyumba cyacecetse. Igishushanyo cyerekanaga umutwaro (ibisabwa byose ukuyemo izuba) bigabanuka saa sita izuba rirenze, hanyuma rikarasa izuba rirenze. Icyo gipimo cya ramp - kiva byibuze kugeza hejuru mumasaha 3 - byacitse uko ibikorwa bya gride byakoraga. Ugomba kugumisha ibihingwa bya gaze kuzunguruka mugihe cya nyuma ya saa sita kugirango ukemure nimugoroba. Birahenze, bidakora neza, kandi mubucucu.

Umusore umwe inyuma yabajije ati: "Ntidushobora kugabanya izuba gusa?" Injeniyeri arahagarara. "Twabishobora. Cyangwa twashoboraga kumenya ububiko."

Ububiko. Iburyo.

Kuruhande rwihuta - niki na grid - ububiko bwapima? Baza abantu batanu, shaka ibisubizo bitandatu. Ubwumvikane buke ni ikintu cyose kirenga megawatt 1, ariko nicaye mu nama ziterana aho abantu batonganye kuriyi minota makumyabiri. Gusaba bifite akamaro kuruta ubushobozi? Niba ufite kilowati 500 ikora insimburangingo ikomeye, ibyo birabaze?

Hano hari Californiya - Moss Landing, ngira ngo - irenga MW 400. Birashoboka kuba 450. Ahari 420. Ingingo ni, kuvuga ko hamwe numushinga wa MW 1 wumva ari bibi, ariko inganda ntizashingiye kumagambo meza. Turimo kuvuga kububiko bugira ingaruka mubikorwa bya gride. Ntabwo Tesla Powerwall y'umuturanyi wawe.

Dore ibisekeje. Abantu bose bavuga kuri bateri ubu, ariko pompe hydro iracyiganje mububiko bwisi. Ntanubwo ari hafi. Kuvoma amazi hejuru mugihe amashanyarazi ahendutse, reka asubire muri turbine mugihe ibiciro bizamutse. Intara ya Bath muri Virijiniya ikora ibi kuva 1985. MW irenga MW 3.000. Imikorere ni nziza - 70-80% urugendo ruzenguruka - kandi "lisansi" namazi ukoresha ubuziraherezo.

Ikibazo ni geografiya. Ukeneye imisozi, ibibanza bibereye, ahantu hubatswe ingomero ntizuzura ikintu abantu bitaho. Imbuga nyinshi zo muri Amerika zateye imbere mu ntangiriro ya 90. Ibyifuzo bishya bigaragara rimwe na rimwe ariko kubyemera bifata igihe kirekire kuburyo abaterankunga bakunze kureka. Hano hari umushinga muri Montana umaze imyaka 15 utegura. Ntabwo yubatswe.

Umwuka ucogoye urahari kandi, gake. Ibimera bibiri ku isi: Huntorf mu Budage (1978) na McIntosh, Alabama (1991). Nibyo. Tekinoroji ikora neza - kuvoma umwuka mubuvumo bwo munsi, kurekura binyuze muri turbine nyuma - ariko ukeneye geologiya yihariye. Amabuye yumunyu cyangwa ibigega bya gaze byagabanutse bifite imitungo iboneye. Ibihingwa byombi bihari bitwika gaze karemano mugihe cyo kwaguka bigabanya inyungu zibidukikije. Ibishushanyo bishya "adiabatic" bivuga ko bishobora gukuraho gutwika gaze. Nta n'umwe wagabanije ubucuruzi.

Batteri rero. Abantu bose bishimiye bateri ubu ariko ntabwo buri gihe byari bimeze gutya. Ibiciro byari bibujijwe kugeza wenda 2012 - 2015. Hariho igikoresho gito muri Notree Wind Farm muri Ositaraliya mumwaka wa 2012, gihamya - yigitekerezo kirenze ubukungu bufatika.

Hanyuma Tesla yubatse Hornsdale . 2017, Ositaraliya yepfo, 100 MW / 129 MWh. Elon yakoze Twitter yemeza ko yubaka muminsi 100 - bisanzwe Elon - kandi babikoze nkiminsi 63. Abantu bibanze ku muvuduko wo kubaka ariko inkuru nyayo yari imikorere. Batare yinjije amafaranga byihuse kuruta ibiteganijwe binyuze muri serivisi zishinzwe kugenzura inshuro.

Mubyukuri nasuye ikigo gishinzwe kugenzura gride hanze ya Adelaide wenda amezi 6 nyuma yuko Hornsdale ibaye. Ba injeniyeri bari bagisakuza. Umusore umwe yanyeretse imbonerahamwe yo gusubiza inshuro. Iyo grid frequency yatandukanijwe na 50 Hz, bateri yakosoraga muri milisegonda. Amashanyarazi asanzwe yafashe amasegonda kuko mubyukuri uzunguruka turbine. Ati: "Ninko kugereranya imodoka ya siporo na gari ya moshi."

Icyo gihe cya milisegonda isubiza cyane kuri serivise zimwe na zimwe. Iyo ibikorwa bimaze kubona bateri zishobora gukora ibintu bisanzwe ibisekuruza bidashoboka, imyifatire yahindutse vuba. Mugihe cyumwaka watangiye kubona inzira amatangazo yumushinga.

Imiterere ya chimie irahungabana kuruta ibitabo byubucuruzi byerekana. "Litiyumu - ion" ntabwo ari ikintu kimwe. Imiti myinshi ya chimisties ihurizwa hamwe. Kuri grid porogaramu, lithium fer fosifate yatsinze cyane. LFP, LiFePO4,litiro ion fosifate- amazina atandukanye bitewe ninde uyamamaza.

Ubu chimie yerekana wenda 60 - 65% yububiko bushya bwa Amerika nu Burayi. Imibare iratandukanye bitewe ninde ubara nicyo arimo. Impamvu ifatika: LFP ikora amagare-gusohora amagare neza kuruta ubundi buryo nka NMC (nikel manganese cobalt). Impanuka ziterwa n'umuriro nazo, zifite akamaro mugihe urimo gutondekanya ibikoresho byoherejwe byuzuye na bateri ahantu hatuwe. Tuzagera ku muriro nyuma.

Ubucucike bwingufu buri munsi ya NMC ariko kububiko buhagaze ntacyo bitwaye. Ntabwo ubikwiye munsi yintebe yimodoka. Shyira ibikoresho kugeza igihe ukubise intego.

Bateri zitemba zikomeza kubona ubwishingizi. Sisitemu ya redox itandukanya ububiko bwingufu (ingano ya tank) nimbaraga (ubunini bwa stack). Ikigo cya Dalian mu Bushinwa, cyatangijwe 2022, 100 MW / 400 MWh, kuri ubu kinini. Ibiciro biruta litiro ariko ubuzima bwikiziga burashobora kurenga 20.000 byikurikiranya nta kwangirika gukomeye.

Mubyigisho bifite akamaro kubikorwa byateganijwe 20+ ibikorwa byumwaka. Mubimenyerezo, ibiciro bya lithium bigabanuka vuba kuruta bateri zitemba zifunga icyuho. Bateri zitemba "zimaze gutera imbere" byibuze imyaka icumi. Gutangira kumvikana nkimbaraga zo guhuza.

Ubudage bwamenye ikibazo cyo kubika inzira igoye. Ahagana mu mwaka wa 2011-2012 bahise bafite gigawatts yizuba hejuru yinzu hejuru ya Energiewende. Saa sita zuba, izuba ryarazamutse. Ibicu byanyuze, bigabanuka na gigawatts. Byihuta.

Abakoresha amashanyarazi bakoresheje umwuga wose mugucunga ibyifuzo byateganijwe ubu bakemuye umurongo utanga ibintu byihuta kuruta uko bashobora kubyitwaramo. Guhindura paradigima yuzuye. Umukoresha umwe naganiriye mu nama yabereye i Berlin - uyu ni 2016 wenda - yavuze ko ari bwo bwa mbere abonye igisekuru kigabanuka 5 GW mu minota 20, akeka ko gahunda ye yo gukurikirana yacitse.

Umuyaga ukora ibintu bisa ariko ibihe bitandukanye. Sisitemu yo hejuru - parike yumuvuduko hejuru yimirima yumuyaga kandi ibisekuruza bigabanuka kubusa. Gumayo iminsi. Ntushobora guhamagara umurima wumuyaga saa kumi n'ebyiri za mugitondo ukabibwira kubyara byinshi kuko abantu murugo bateka ifunguro rya nimugoroba. Ntabwo ikora muri ubwo buryo.

Igihe cyo gusubiza ni ingenzi kuri porogaramu zimwe. Californiya ISO isaba serivisi ishinzwe kugenzura inshuro nyinshi imbaraga muminota 10. Birashobora kuba iminota 8, ngomba kugenzura spes. Serivisi zimwe zikeneye sub - igisubizo cya kabiri. Batteri nziza cyane - reaction ya electrochemical reaction ni ako kanya uhereye kubakoresha gride.

Hydro yavomwe ikenera amasegonda 10-15 kugirango amazi atemba yihuta binyuze muri turbine, wongeyeho ibikorwa bya valve. Icyo cyuho gifite akamaro ko kugenzura inshuro. Ntacyo bitwaye cyane kogosha impinga aho usohora amasaha.

Imikorere igena niba imishinga yinjiza amafaranga. Imibare shingiro: kubika MWh 100, kugarura MWh 90, wabuze 10% buri cyiciro. Litiyumu ikubita 85-95% ukurikije iboneza nuburyo ubisunika. Bateri zitemba cyane nka 65-75%. Bisa nkibyoroheje ariko gusiganwa ku magare burimunsi kumyaka 15, iyo delta ikora neza ihuza miriyoni mugutandukanya kwinjiza. Ahari miliyoni mirongo kumishinga minini.

Ubuzima bwikiziga bugorana. Sisitemu nyinshi za gride lithium ikora 20 - 80% yuburyo bwo kwishyuza kuruta gusiganwa ku magare. Gutamba 40% ubushobozi bwizina ryikubye kabiri cyangwa gatatu ibikorwa byubuzima. Ubukungu bukora kuko gusimbuza bateri hagati umushinga uhenze rwose. Ibyiza kurenza urugero.

Itegeko ryo kugabanya ifaranga mu 2022 ryahinduye amasoko yo muri Amerika. Reka ububiko bwihariye busabe 30% yinguzanyo zishoramari. Mbere yububiko bwujuje ibyangombwa gusa byahujwe nizuba cyangwa umuyaga, byari politiki yubucucu ariko niko byanditswe.

IRA imaze gutsinda, amatangazo yumushinga yuzuye. Umurongo wo guhuza wari ufite 85+ GW yo kubika hagati ya 2023. Umuntu wese umenyereye umurongo uhuza azi imishinga myinshi itigera yubaka nubwo. Ibipimo byo kurangiza amateka bikora 20-30% nibyiza.

Nari mu nama yabatezimbere yabereye i Houston umwaka ushize - umusore wo mu ruganda rukomeye rw’Abashinwa yavuze ko badashobora guhaza icyifuzo cya Amerika. "Twongeyeho imirongo itanga umusaruro ariko hari amezi 18 yo kuyobora ku bikoresho." Gutanga inzitizi ahantu hose.

Ububiko bwisi bwageze kuri 27 - 28 GW muri 2023 ukurikije uko ubara . 90% byiterambere byabaye kuva muri 2018. Amerika yongeyeho 4.8 GW muri 2022 yonyine, ishobora kuba yari 5.2, ngiye kwibuka. Californiya na Texas biganje kubyoherezwa kubwimpamvu zitandukanye rwose. Californiya ifite politiki ishinzwe gutwara ibishobora kuvugururwa. Texas ifite ingufu za ERCOT - isoko gusa itera ihindagurika ryinshi ryibiciro. Abashinzwe ububiko bakunda guhindagurika - koresha ibyo bihindagurika.

Ibiciro byagabanutse kuva hejuru ya $ 500 / kWt muri 2015 kugeza $ 150-200 / kWt muri 2023 kuri sisitemu yuzuye. Abantu bamwe bavuga ko ari hasi ariko $ 150-200 nibyo nabonye kubikorwa bifatika. Igipimo cyo gukora cyane cyane, irushanwa rikaze mubakora selile zo mubushinwa na koreya.

Uburyo bwo kwinjiza buratandukanye cyane ku isoko. Texas ERCOT ireka isoko ryo kubika isoko ryingufu. Urwo rugi rwimbeho Uri kuva rwatangira - bamwe mubakozi bahanaguye $ 10+ miliyoni, ahari miliyoni 12, numvise imibare itandukanye. Ntabwo ari ibisanzwe nubwo.

Ibikorwa bisanzwe birimo gutondekanya amafaranga yinjira: ubukemurampaka bwingufu (kwishyuza bihendutse, gusohora bihenze), kwishyura ubushobozi, kugenzura inshuro, rimwe na rimwe kuzamura kwimurwa. SGIP ya Californiya itera imbere hejuru cyane cyane kubikorwa bikomeye.

Umukoresha umwe yambwiye - ku rutonde rwabari mu kabari mu nama - ko kimwe cya kabiri cy’amafaranga bateganijwe kiva muri serivisi zitabayeho mu myaka itanu ishize. "Ibi turabikora uko tugenda. Abakoresha amashanyarazi barimo kumenya icyo bateri zishobora gukora mu gihe nyacyo."

Ikiringo gikomeje kuba inzitizi igaragara kandi birababaje. Sisitemu nyinshi zisohora amasaha 2 - amasaha 4 ku mbaraga zagenwe. Utunganye impinga ya nimugoroba iyo izuba ritonyanga. Ntabwo rwose bimaze kubikwa iminsi myinshi mugihe cyikirere cyagutse.

Tekinoroji igihe kirekire komeza utangarizwe hamwe nibitangaza makuru. Umwuka ucanye, sisitemu ya rukuruzi, ububiko bwumuriro. Kohereza ubucuruzi biracyoroshye. Umuntu wese arashaka 8+ kubika amasaha, bamwe bashaka 12 cyangwa 24. Ntamuntu numwe wabonye ubukungu mubipimo kugeza ubu.

Hano mubyukuri gutangira guterura bisi hamwe na crane kugirango ubike ingufu. Byumvikane neza ariko physics irakora. Nta n'umwe wigeze apima nubwo. Kimwe nububiko bwumuriro.

Kwangirika kwa Batteri muburyo bwo gusiganwa ku magare bikomeje gutangaza abakoresha, birambabaza kuko wagira ngo twabimenye kugeza ubu.

Kwipimisha muri laboratoire ntabwo byerekana imikorere yumurima neza. Kwishyiriraho hakiri kare - 2018, igihe cyagenwe cya 2019 - cyerekeje cyane kurenza uko byari byateganijwe, bigabanya ubuzima bwimikorere byihuse kuruta uko byari byitezwe, garanti yingwate isubirwamo. Uburyo bwiza bwo gutesha agaciro burahari ubu ariko gushidikanya biracyari hafi 10+ imikorere yumwaka, cyane cyane ko ingamba zo kohereza zigenda zihinduka.

Ntushobora kugerageza imyaka 15 yimikorere mugihe cyimyaka 2 yiterambere. Ntibishoboka. Injeniyeri muri NREL yambwiye ko bubaka moderi zishoboka zishingiye kumibare mike. "Turimo kohereza mu myaka 5 dukora kugira ngo tumenye imyaka 20. Byizewe gukeka."

Umutekano wumuriro ntiwazimye nubwo ibipimo byateye imbere. Umuriro wa McMicken muri Arizona - Mata 2019 - ukomeje kuba ibintu bikomeye. Igisasu cyakomerekeje abashinzwe kuzimya umuriro bane, byashoboraga kuba bibi.

Naganiriye numwe mubasubije bwa mbere mu nama yumutekano. Yavuze ko bahageze, protocole isanzwe yavuze ko gutera amazi ku muriro wa batiri. Yatangiye kubikora. Hanyuma iraturika. "Nta muntu n'umwe watubwiye ko ibyo bintu bishobora guhunga umuriro ndetse n'umuriro umaze kuzimya."

Ibyo birori byagaragaje uburyo inganda zasobanukiwe nabi gukwirakwiza amashanyarazi muri sisitemu yabitswe. Twatekereje ko tubizi. Biragaragara ko tutabikoze. Ibipimo byo kwipimisha byateye imbere cyane nyuma. UL 9540A yabaye igipimo abantu bose bavuga.

Ariko buri shimi nshya ya chimie ikeneye isuzumabumenyi guhera. Abacuruzi bose ntibakurikiza uburyo bumwe bwo gushushanya utugari, gukonjesha, kuzimya umuriro. Bamwe bakora byibura code isabwa. Abandi barenze urugero. Ntushobora buri gihe kubwira ibicuruzwa byamamaza umushinga ukoresha. Icyo ni ikibazo.

Australiya yepfo itanga incamake yigihe kizaza -. Ububiko bugera kuri 300 MW butanga hafi MW 2000 ikenewe cyane muri 2022.Ni nka 15% byingufu zikenewe mububiko. Ibyingenzi.

Byahinduwe muburyo bwa gride ibikorwa. Ariko ubutegetsi butandukanye cyane na Texas cyangwa Californiya aho ububiko bukomeza kuba ijanisha rito ryubushobozi bwose. Urashobora gupima uburyo Australiya yepfo ikora ERCOT? Birashoboka, birashoboka.

Nabajije umuyobozi wa gride ya Australiya yepfo kubyerekeye ibi mu nama. Igisubizo cye: "Turi urubanza rw'ibizamini. Niba ruvunitse hano, byibuze turi bato bihagije ku buryo gutsindwa birimo." Ntabwo ari ibyiringiro neza - bitera imbaraga ariko ni inyangamugayo.

grid-scale energy storage

NREL itegura ikintu nka 250+ GW US US muri 2050 mugihe gishobora kuvugururwa. Cyangwa yari 300 GW? Ningomba kubishakisha. Niba ibyo bibaho biterwa nibintu byinshi. Gukomeza kugabanya ibiciro biragaragara. Inkunga ya politiki igumaho, itigera yemerwa. Abakoresha amashanyarazi bahindura imikorere yimikorere aho kubivuga gusa.

Ibiteganijwe kuva mumyaka itanu ishize birasa nkibisanzwe. Kohereza byarenze ibyateganijwe mbere. Ariko ibindi biteganijwe birashobora kwerekana ko byiringiro mugihe ibitekerezo byingenzi bidafashe cyangwa ikintu gitunguranye kibaye. Biragoye kubivuga.

Imiti mishya ikomeza kugaragara muri laboratoire yubushakashatsi. Sodium - ion isezeranya ibiciro byo hasi kuko udakoresha lithium. Zinc - ikirere gisaba ubucucike buri hejuru. Ibindi bintu nshobora kuba nibagiwe. Hoba harimura lithium - ion ya porogaramu ya grid? Birashoboka ko atari byose, byaba ari byo nkeka. Tekinoroji iriho ifite inganda nini abashya ntibashobora guhura vuba. Bifata imyaka yo kubaka inganda.

Birashoboka cyane ko chemisties zitandukanye zishakisha ibyingenzi zishingiye kumbaraga zihariye. Isoko riratandukanye bihagije kugirango rishyigikire inzira nyinshi, ukeka ko zigeze mubucuruzi kandi ntizigume mumishinga yicyitegererezo ubuziraherezo.

Ububiko bwatangiye nkibisubizo byigihe gito ariko byahindutse mugari. Noneho nigikoresho cya grid flexible utitaye kumasoko yibisekuru. Simbuza turbine zo gutwika kugirango ugenzure inshuro. Hindura uburyo bwogukwirakwiza buhenze mugucunga ibibazo byaho. Tanga umukara - gutangira ubushobozi bwo kugarura gride nyuma yo guhagarara gukomeye.

Izi porogaramu zifite akamaro niba kwinjirira gushya gukubita 80% cyangwa kuguma kuri 40% cyangwa aho bigarukira.

Ubukungu komeza gutera imbere buhoro buhoro. Ingano yimodoka itwara ibiciro buri mwaka. Imikorere ya Batteri - ubwinshi bwingufu, ubuzima bwikiziga, ibyo byose - bitezimbere buhoro buhoro. Niba ububiko bwahindutse igisubizo cyoroshye cyangwa igisubizo kimwe gusa muri byinshi (igisubizo gisabwa, uburyo bwiza bwo kohereza, guhanura neza) buracyari ikibazo gifunguye gishobora kutazasubizwa mumyaka icumi cyangwa ibiri.

Ikigaragara neza: gride irahinduka muburyo bwibanze. Ubuhanga bwo kubika - uburyo bwose bafata - butuma byinshi bihinduka. Ibyo birasa nkaho ari ukuri.

Garuka kuri uriya mukoresha wa Texas mugihe cyumuyaga Uri. Nyuma yuko ibiciro bisubiye mubisanzwe kandi ikibazo kirangiye, namubajije icyo yize. Kuruhuka birebire. "Ko bateri zishobora gukora akazi. Ariko nanone ko nta muntu uzi icyo bakora kugeza ubu. Twese hamwe turabishakira hamwe."

Umva neza.

EIA itangaza imibare yo kubika buri kwezi. Nibyiza kwizerwa nubwo bisohoka bitinze. Bloomberg NEF ikora uko umwaka utashye, ukeneye kwiyandikisha bihenze. NREL ikora imibare yububiko, amakuru atinda kwukuri kumezi 12-18. Biracyafite akamaro kubwintego zinyigisho.

Wood Mackenzie nibindi bigo bisa nibitangaza. Kurikirana inyandiko yukuri - ubwenge mugihe cyigihe kirekire cyabaye, reka tuvuge bivanze. Bahoraga basuzugura igipimo cyo kohereza 2018-2022. Byendagusetsa.

Ibitabo byubucuruzi nka Utility Dive hamwe nububiko bwingufu Amakuru akubiyemo imishinga neza. Komeza ugana ibyiringiro nubwo. Kimwe cya kabiri cyibintu batangaza ngo "biza vuba" ntabwo bigera mubikorwa byubucuruzi. Fata umunyu.

Hagize ibiganiro byingirakamaro mumyaka hamwe naba injeniyeri muri California ISO, ERCOT, Imiyoboro Yamashanyarazi ya Ositaraliya yepfo, wongeyeho abakora mumanama atandukanye (Austin, San Diego, Berlin, Adelaide). Ibintu byinshi byamakuru byaturutse mubiganiro byabari nyuma yinteko zemewe zirangiye.

Amakuru agezweho guhera 2023 cyangwa muntangiriro ya 2024. Inganda zirahinduka byihuse ugomba kugenzura imibare yihariye niba uyikoresha kubintu byingenzi. Ntukavuge gusa iyi ngingo - Ndi umuntu kuri enterineti.
