Dzuwa lambiri lidawonongeka

Bungwe la World Energy Council likuyerekeza kuti kufunikira kwa mphamvu padziko lonse lapansi mu 2020 kudzakhala pafupifupi 14 Gtoe, kapena 588 trilioni joules. Pafupifupi ma petawati 89 a mphamvu ya dzuwa amafika padziko lapansi, motero timalandila pafupifupi ma quadrillion joules atatu kuchokera ku Dzuwa chaka chilichonse. Nkhanizi zikuwonetsa kuti mphamvu zonse zochokera ku Dzuwa masiku ano zikuchulukirachulukira pafupifupi zikwi zisanu kuposa zomwe anthu akuyembekezeredwa mu 2020.

Zosavuta kuwerengera. Izi ndizovuta kugwiritsa ntchito. Asayansi akugwirabe ntchito yokonza ma cell a photovoltaic. Pakati pa zomwe zilipo pamsika lero, nthawi zambiri sizidutsa ... 10 peresenti ya kugwiritsa ntchito mphamvu za dzuwa zomwe zilipo. Kugwiritsa ntchito mphamvu kwa ma cell a solar amakono a crystal silicon ndi okwera mtengo kwambiri - mwa kuyerekezera kwina, pafupifupi kuwirikiza kakhumi kuposa malasha.

Kuti apitirize mutu wa nambala Mudzapeza m’kope la July la magazini.
