Mbiri ya Chitukuko cha Zomera Zamagetsi
Magetsi ndi chimodzi mwa zinthu zomwe zapezeka kwambiri m'mbiri ya chitukuko cha anthu. Pafupifupi ntchito zonse zamakono—kuyambira kuunikira ndi kulumikizana mpaka mafakitale ndi chisamaliro chaumoyo—zimadalira kupezeka kwa mphamvu zamagetsi. Komabe, magetsi sapezeka nthawi zonse monga momwe alili masiku ano. Kumbuyo kwa kusavuta kuyatsa nyali kapena kuchaji foni yam'manja kuli mbiri yakale yopanga magetsi, yokhudzidwa ndi zomwe asayansi apeza, kupita patsogolo kwaukadaulo, zosowa zachuma, ndi zovuta zachilengedwe. Nkhaniyi ikuwunika mbiri yopanga magetsi, kuyambira masiku ake oyambirira mpaka nthawi ya mphamvu zongowonjezwdwanso.
Chiyambi cha Kupezeka kwa Magetsi ndi Zoyambira za Sayansi ya Magetsi
Mbiri ya magetsi imayamba ndi kuwona zochitika zachilengedwe. Kuyambira ku Greece wakale, anthu akhala akudziwa za magetsi osasinthasintha, monga momwe amber akapakidwa amakokedwa ndi kuwala. Komabe, kumvetsetsa kwa sayansi kunapita patsogolo mofulumira m'zaka za m'ma 17 ndi 18. Anthu ngati William Gilbert anaphunzira za mphamvu ya magetsi ndi maginito, pomwe Benjamin Franklin ndi wotchuka chifukwa cha kuyesa kwake kwa kite, komwe kunatsimikizira kuti mphezi ndi chinthu chamagetsi.
Kupita patsogolo kwakukulu komwe kunayambitsa njira yopangira magetsi kunali kupeza ubale pakati pa magetsi ndi maginito. Mu 1831, Michael Faraday adapeza mfundo ya kulowetsa magetsi m'magetsi: mphamvu ya maginito yosintha imatha kupanga magetsi. Mfundo imeneyi inakhala maziko a jenereta yamagetsi yamakono. Pa nthawiyi, magetsi sanalinso chinthu chongochitika m'ma laboratories okha, koma mtundu wa mphamvu womwe ungapangidwe pamlingo waukulu.
Kutuluka kwa Jenereta Yoyamba ndi Malo Opangira Magetsi
Pambuyo pa Faraday, asayansi ndi mainjiniya osiyanasiyana adapanga ma dynamo ndi ma jenereta. Pofika pakati pa zaka za m'ma 19, kupanga magetsi kunayamba kugwiritsidwa ntchito pang'ono, makamaka powunikira. Munthu wina amene anayambitsa kugwiritsa ntchito magetsi anali Thomas Alva Edison. Mu 1882, Edison adamanga fakitale yogwiritsa ntchito nthunzi ku Pearl Street, New York, yomwe nthawi zambiri imaonedwa kuti ndi imodzi mwa mafakitale oyamba amagetsi padziko lonse lapansi. Kampaniyo idapereka magetsi amagetsi olunjika (DC) kuti ayatse nyali zowala m'dera lozungulira.
Ngakhale kuti inali yosinthika, dongosolo la DC linali ndi vuto lalikulu: magetsi sakanatha kufalikira bwino pamtunda wautali chifukwa cha kutayika kwa mphamvu zambiri. Kuchepa kumeneku kunali chimodzi mwa zinthu zomwe zinayambitsa "Nkhondo ya Mitsinje" pakati pa ochirikiza mphamvu yamagetsi yolunjika (DC) ndi mphamvu yamagetsi yosinthasintha (AC).
Kulamulira kwa Machitidwe Ena Amphamvu Amakono ndi Amakono
Nikola Tesla ndi George Westinghouse adalimbikitsa njira yothandiza kwambiri yosinthira magetsi (AC) yotumizira magetsi mtunda wautali chifukwa mphamvu yake imatha kukwezedwa ndi kutsika pogwiritsa ntchito ma transformer. Ubwino uwu unapangitsa kuti AC ikhale muyezo waukulu wa gridi yamagetsi padziko lonse lapansi.
Chinthu chofunika kwambiri chinachitika mu 1895 pamene fakitale yamagetsi yamadzi ku Niagara Falls inayamba kugwira ntchito ndikutumiza magetsi ku Buffalo, New York. Izi zinasonyeza kuti magetsi akhoza kupangidwa pamlingo waukulu ndikugawidwa kumizinda yakutali. Kuyambira pamenepo, kumanga mafakitale amagetsi ndi maukonde otumizira magetsi kwakula mofulumira m'maiko ambiri.
Nthawi ya Zomera Zamagetsi Zogwiritsa Ntchito Nthunzi ndi Malasha
Kulowa m'zaka za m'ma 20, kufunika kwa magetsi kunakula kwambiri pamene mafakitale anayamba kukula. Malo opangira magetsi pogwiritsa ntchito nthunzi anakhala njira yofala kwambiri, pogwiritsa ntchito kutentha kwa makala oyaka kuti apange nthunzi yomwe inasintha ma turbine. Malasha anasankhidwa chifukwa cha kuchuluka kwake komanso kutsika mtengo kwake. Malo opangira magetsi pogwiritsa ntchito nthunzi pogwiritsa ntchito malasha anakhala maziko a magetsi ku Ulaya, America, komanso m'mayiko ambiri osatukuka.
Ukadaulo wa makina oyendera nthunzi unkakonzedwanso nthawi zonse, zomwe zinkawonjezera mphamvu. Pakati pa zaka za m'ma 20, lingaliro la makina olumikizirana amagetsi linayamba kuonekera. Kulumikizana pakati pa madera kunalola kuti magetsi azikhala okhazikika, kuchepetsa kuzimitsidwa kwa magetsi, komanso kuwonjezera mphamvu ya magetsi m'malo opangira magetsi.
Kukonza Magetsi Ochokera Madzi ndi Madamu Aakulu
Kupatula malasha, magetsi opangidwa ndi madzi akhala gwero lofunika la mphamvu kuyambira pachiyambi cha magetsi. Malo opangira magetsi opangidwa ndi madzi (PLTA) amagwiritsa ntchito mphamvu zomwe zimapezeka m'madamu kapena mitsinje. Kumayambiriro kwa zaka za m'ma 20, mayiko ambiri adamanga madamu akuluakulu, monga Damu la Hoover ku United States, lomwe linamalizidwa mu 1936 ndipo ndi chizindikiro cha kusintha kwamakono.
Malo opangira magetsi pogwiritsa ntchito madzi ali ndi ubwino woti safuna mafuta ochokera ku zinthu zakale komanso mpweya wochepa wa kaboni. Komabe, kumanga madamu akuluakulu nthawi zambiri kumakhala ndi zotsatirapo pa chikhalidwe cha anthu komanso zachilengedwe, monga kusamuka kwa anthu, kusintha kwa zachilengedwe m'mitsinje, komanso kusungunuka kwa nthaka. Komabe, m'mbiri ya mphamvu zamagetsi, malo opangira magetsi pogwiritsa ntchito madzi akadali njira yatsopano yoperekera magetsi ambiri.
Kutuluka kwa Malo Opangira Mafuta ndi Gasi
Pambuyo pa Nkhondo Yachiwiri Yapadziko Lonse, kugwiritsa ntchito mafuta ndi gasi kunakula, kuphatikizapo kupanga magetsi. Malo opangira magetsi opangidwa ndi mafuta ankagwiritsidwa ntchito kwambiri chifukwa anali osinthasintha komanso osavuta kumanga. Komabe, vuto la mafuta la m'ma 1970 linapangitsa mayiko ambiri kudziwa za kuopsa kodalira mafuta ochokera kunja. Kuyambira pamenepo, gasi wachilengedwe wakhala chisankho chodziwika kwambiri, choonedwa kuti ndi choyera kuposa malasha ndi mafuta, komanso chogwira ntchito bwino kwambiri, makamaka kudzera muukadaulo wophatikizana (malo opangira magetsi a gasi ndi nthunzi), omwe amagwiritsa ntchito kutentha kotayika kuti apange magetsi owonjezera.
Nyengo ya Nyukiliya: Chiyembekezo ndi Mikangano
Pakati pa zaka za m'ma 20, mphamvu ya nyukiliya inayamba kugwiritsidwa ntchito ngati chizindikiro cha kupita patsogolo kwa ukadaulo. Malo oyamba opangira mphamvu ya nyukiliya kwa anthu onse anayamba kugwira ntchito ku Soviet Union mu 1954. Ukadaulo umenewu unalonjeza kuti padzakhala magetsi ambiri okhala ndi mpweya wochepa kwambiri wa carbon. Mayiko ambiri pambuyo pake adamanga ma reactor a nyukiliya ngati gawo la njira zawo zadziko lonse zopangira mphamvu.
Komabe, ngozi zazikulu monga Three Mile Island (1979), Chernobyl (1986), ndi Fukushima (2011) zinayambitsa nkhawa padziko lonse lapansi pankhani ya chitetezo cha nyukiliya komanso kasamalidwe ka zinyalala za radioactive. Zotsatira zake, chitukuko cha nyukiliya chinachepa m'maiko ena, ngakhale m'maiko ena chikadali gawo lofunikira la kusakaniza mphamvu.
Kukwera kwa Mphamvu Zongowonjezedwanso: Dzuwa ndi Mphepo
Pamene zaka za m'ma 20 ndi 21 zinkayandikira, kusintha kwa nyengo ndi kuipitsidwa kwa chilengedwe kunayambitsa kusintha kwakukulu pa mphamvu zongowonjezwdwanso. Mphamvu ya mphepo (WPP) ndi mphamvu ya dzuwa (PLTS) zinakwera kwambiri pamene mitengo ya ukadaulo inatsika kwambiri ndipo thandizo la mfundo za boma linawonjezeka. Mapanelo a dzuwa omwe kale anali okwera mtengo kwambiri anayamba kukhala otsika mtengo kwambiri, pomwe ma turbine a mphepo anayamba kukula komanso kugwira ntchito bwino.
Vuto lalikulu la mphamvu ya dzuwa ndi mphepo ndilakuti mphamvu zake sizisintha, kutengera nyengo ndi nthawi ya tsiku. Chifukwa chake, makina amakono opangira magetsi akusinthira ku malingaliro anzeru a gridi, kusungira mphamvu (mabatire akuluakulu), komanso kuphatikiza magwero osiyanasiyana amagetsi kuti magetsi azikhala okhazikika.
Kupanga Mphamvu Zamakono: Kugwira Ntchito Mwanzeru, Kusintha kwa Digito, ndi Kusintha kwa Mphamvu
Padziko lonse lapansi pakali pano pali kusintha kwa mphamvu. Mayiko ambiri akuyesetsa kuchepetsa kugwiritsa ntchito malasha ndikuwonjezera mphamvu zongowonjezwdwanso kuti achepetse mpweya woipa womwe umawononga chilengedwe. Ukadaulo wopanga magetsi ukukulirakulirabe: masensa, luntha lochita kupanga, ndi makina owongolera okha amathandiza kukonza magwiridwe antchito, kulosera kulephera, komanso kuyang'anira kugawa kwa mphamvu zamagetsi.
Kuphatikiza apo, ukadaulo watsopano ukubwera, monga malo okhazikika, otulutsa mpweya wochepa, malo opangira mphamvu za biomass, ndi lingaliro la haidrojeni wobiriwira ngati malo osungira mphamvu zongowonjezwdwanso. M'tsogolomu, malo opangira mphamvu sadzangoyang'ana pa kupanga mphamvu zokha komanso pa kukhazikika, kulimba kwa dongosolo, komanso kusintha kwa chikhalidwe cha anthu.
Kutseka
Mbiri ya kupanga magetsi ndi nkhani ya zatsopano komanso kufunikira kwa anthu kukhala ndi moyo wabwino komanso wopindulitsa. Kuyambira pakuyesera kosavuta ndi magetsi osasinthasintha mpaka ma gridi akuluakulu amagetsi olumikiza mayiko ndi makontinenti, ulendowu wasintha dziko lamakono. Masiku ano, vuto lalikulu silikungopanga magetsi okha, koma kupanga magetsi oyera, otetezeka, otsika mtengo, komanso okhazikika. Ndi kupita patsogolo kwaukadaulo komanso chidziwitso cha chilengedwe padziko lonse lapansi, tsogolo la kupanga magetsi likuyembekezeka kulamulidwa kwambiri ndi mphamvu zongowonjezedwanso komanso machitidwe anzeru, zomwe zikuwonetsa mutu watsopano m'mbiri ya mphamvu zamagetsi za anthu.
