Mu gihe c’uguhinduka kw’inguvu kw’isi yose, imodoka nshasha z’inguvu ziriko ziratera imbere ku rugero rutari rwo. Gutera ibirundo, nk’ibikorwa remezo bihambaye vyo gufasha izo modoka, birafise uruhara runini. Igihimba cabo nyamukuru, ni co kibanza co gushaja, gikora nk’igihuhusi c’ububasha mu gihe gishasha c’inguvu, kigatanga umushinge ukomeye w’ugutembera kw’ivyatsi bitotahaye.
Igikoresho co gushaja ni igikoresho gikomeye gishiramwo ibikoresho bitandukanye vy’umuyagankuba n’ibikoresho vyo kugenzura. Igikorwa cayo nyamukuru ni uguhindura ubushobozi bwa AC kuva ku ruzitiro bikaja mu DC bikwiye gukoreshwa mu gushaja imodoka zikoreshwa n’umuyagankuba no kugenzura neza no gucunga neza uburyo bwo gushaja. Mu mutima, igizwe n’ibice nyamukuru nk’igice c’umurongo, umurongo w’amashanyarazi, igice c’igenzura, igice co gupima, igice c’itumanaho, n’igice c’uburinzi.
Igikoresho c’ubuhinga bwa none gihindura ububasha bwa - bwo gupfira AC muri DC, bugatanga inkomoko y’ububasha y’ishimikiro yo guhindura uburyo bwo gushaja. Igikoresho c’amashanyarazi kiduga canke kimanuka ku bubasha bwa DC butegekanijwe hakurikijwe ibisabwa n’ugushaja, kugira ngo umuriro n’umuriro w’amashanyarazi bishobore gushitsa ku bijanye n’ugushaza kw’amabateri atandukanye y’imodoka y’umuyagankuba. Ico gice c'igenzura gikora nk'"ubwonko." Ukoresheje ubuhinga butoroshe n’ubuhinga bwa porogarama, irakurikirana kandi igenzura uburyo bwose bwo gushaja mu gihe nyaco, harimwo no gushaja no guhagarika, guhindura uburyo bwo gushaja, no gupima amakosa no gukoresha, kugira ngo umuntu ashobore gushaja mu buryo butekanye kandi akora neza.
Igikoresho co gupima neza ibipimo vy’amashanyarazi mu gihe c’ugucapura, nk’urugero rw’amahera, igihe co gushaja, n’ububasha bwo gushaja, kandi kigatanga aya makuru ku buryo bwo gucunga inzego z’amashanyarazi ku bakoresha kugira ngo bashobore gucungera amakuru no gusuzuma amakuru. Iryo soko ry’itumanaho ryorosha guhana amakuru hagati y’imirongo n’imirongo y’inyuma, ivyumba vy’abakoresha, n’uburyo bwo kugenzura inyuma, bituma abakoresha bashobora kubona kure y’aho basaba n’urutonde rw’ibintu vyo gushaja. Bituma kandi abakoresha bashobora gucunga neza no kubungabunga umubare munini w’ibibanza vyo gushaja. Ico gikoresho co gukingira kiguma gikingira neza ibihimba vy’umuyagankuba vy’ico kibanza. Iyo umuntu abonye ibintu bitari vyo nk’umuriro urenze urugero, ukomeye cane, ushuha cane, canke n’imirongo miremire, bica bigabanya ningoga umuzunguruko kugira ngo umuntu areke gutera imbere kw’ikosa no kugabanya ingorane zishobora guterwa n’umutekano ziterwa n’impanuka z’umuyagankuba.
Muri make, nk’ibikorwa remezo nyamukuru mu gihe gishasha c’inguvu, ibikoresho vyo gushaja birafise uruhara rudasubirizwa mu guteza imbere iterambere ry’ubuhinga bushasha bw’imodoka n’uguhindura imiterere y’inguvu. Naho hari ingorane nyinshi, n’ubuhinga bushasha bukomeza, ukukura buhoro buhoro kw’isoko n’ugushigikira gukomeye kw’ingingo ngenderwako, inganda y’ibikoresho vy’ubuhinga bwo gushaja izotanga ata gukeka mu bijanye n’iterambere ry’iterambere ry’ibintu vyiza kandi ritere imbere mu kwubaka uburyo bwo gukoresha inguvu zisukuye, ziri hasi.
