Muri 2019, ingufu z'amakara ziracyari uburyo bw'amashanyarazi muri Amerika, bingana na 23.5%, butanga ibikorwa remezo byo gukwirakwiza amakara akomoka ku makara. Amashanyarazi ya biyomasi afite munsi ya 1% gusa, naho andi 0.44% yimyanda hamwe n’amashanyarazi ya gaze rimwe na rimwe ashyirwa mu kubyaza ingufu za biomass.

Mu myaka icumi ishize, amashanyarazi y’amakara yo muri Amerika yagabanutse ku buryo bugaragara, kuva kuri tiliyoni 1.85 kWh mu mwaka wa 2010 agera kuri tiriyari 0,996 mu mwaka wa 2019. Amashanyarazi y’amakara yagabanutseho hafi kimwe cya kabiri, kandi umubare w’amashanyarazi yose nayo wiyongereye uva kuri 44.8 . % Yagabanutse kugera kuri 23.5%.

Amerika yatangiye ubushakashatsi no kwerekana imishinga yo kubyara ingufu za biomass mu myaka ya za 90. Ubwoko bwo gutekesha gutwikwa hamwe burimo itanura rya gride, itanura rya cyclone, ibyuka bifatika, kurwanya ibyuka, ibitanda bitemba nubundi bwoko. Icyakurikiyeho, hafi kimwe cya cumi cy’amashanyarazi arenga 500 y’amashyanyarazi yakoresheje ingufu za biomass zifatanije n’amashanyarazi, ariko muri rusange ikigereranyo kiri muri 10%. Igikorwa nyirizina cyo gutwika biomass nacyo ntigikomeza kandi gikosowe.

Impamvu nyamukuru yo kubyara ingufu za biomass muri Amerika ni uko nta politiki imwe kandi isobanutse yo gushimangira. Amashanyarazi akoreshwa namakara rimwe na rimwe akoresha amavuta ya biomass ahendutse nka chipi yinkwi, amasano ya gari ya moshi, ifuro ya furo, nibindi, hanyuma agatwika biomass. Ibicanwa ntabwo ari ubukungu. Hamwe n’iterambere rikomeye ry’amashanyarazi akomoka ku binyabuzima mu Burayi, abatanga amasoko ajyanye n’inganda zikomoka ku bimera muri Amerika na bo bahinduye amasoko yabo mu Burayi.
