Ubushakashatsi bwerekana ko gusubirira 40% vy’uruvyaro ruhuye n’ibintu bishobora gusubirwamwo bishobora kugabanya ubushobozi bwo gutuma ibintu bigenda neza n’ibice 60%, bikaba bituma habaho ihinduka ry’incuro mu gihe c’imivurungano. Uburyo bwo kutagira ubumara bw’umubiri buragabanya ico kibazo mu kwigana mu buryo bw’ubuhinga bwa none inyifato yo gutuma umuntu agira incuro z’umubiri.

Iherezo ry'Intara

Ugushikama kw’ibintu bigereranya kimwe mu bibazo bihambaye cane vy’ubuhinga mu guhindura inguvu kw’isi yose. Kugumana ububasha bwo kwizigirwa mu gihe uguhindukira ukaja ku masoko ashobora gusubirwamwo bisaba utwigoro duhurikiyeko mu guteza imbere ubuhinga, uguhingura isoko, n’imirongo ngenderwako y’amategeko.

Ivyo bisubizo vy’ubuhinga birabaho kandi birabandanya gutera imbere. Amabateri, ubumuga bwo gukora, uruzitiro{1}} ihindura, n’ubugenzuzi buteye imbere buratanga ibikorwa vy’ugushikama bingana canke vyiza kuruta uburyo bwa kera. Ibiciro vyagabanutse nk’iminzane y’ugushiraho - ibiciro vyagabanutse 90% mu myaka cumi iheze, bihindura ubuzima bw’ubutunzi.

Ivyiyumviro vy’isoko bitegerezwa gutera imbere kugira ngo bishobore gushika ku ntumbero nziza. Inguvu za kera - amasoko gusa adakwiriye uburyo bwo gutanga amategeko y’incuro, infashanyo y’umuriro, n’ukudakora. California, Texas na Australia barateguye ibintu bishasha vy’isoko bitanga mu buryo butomoye intererano z’ugushikama, ivyo bikaba vyatumye habaho ubuhinga bukwiye.

Inzego z’amategeko zisaba guhindura kugira ngo zishobore kwakira ingero nshasha z’ugushikama. Amakode y'ibintu vyanditswe ku bikoresho vy'ubuhinga bwa none bikeneye gusubirwamwo kugira ngo hamenyekane ibisabwa ku bikorwa vy'inverter- bishingiye ku bikoresho. Uburyo bwo gukorana n’abandi butegerezwa gusuzuma ingaruka z’inkomezi n’ugushikama kw’urutonde, atari ubushobozi bwo gukora gusa.

Iryo hinduka risaba ishoramari rikomeye ariko ritanga inyungu nyinshi zirenze ugushikama. Ivyo gukoresha amavuta y’ibisigazwa vy’ibikoko bigabanya imyuka y’ibidukikije, bikaba ari vyo bituma habaho ibintu bitera imihindagurikire y’ikirere. Ububiko n’uguhinduranya ibintu vyiza bituma umuntu ashobora gusubira gukora neza, bigatuma umuntu yihutisha gukuraho ivyuma. Gukurikirana no kugenzura bituma habaho uruzitiro rukomeye rufise ibikoresho vyiza vyo guhangana n’ibintu bikomeye vy’ikirere.

Ugushikama kw’ibintu mu gihe bishobora gusubirwamwo biratandukanye cane n’uburyo bwa kera, ariko buraguma bushoboka biciye mu gutegura neza, gushiramwo amahera, no gukoresha ubuhinga bwa none. Ivyemezo biva mu turere turongoye vyerekana ko inguvu zisukuye n’ububasha bwo kwizigirwa bitarwanya intumbero- ari intumbero z’inyongera zisaba ko umuntu yiyumvirwa.
