Umthombo wamandla oqhathaniswa

Ihora ngalinye le-kilowatt linembali efihlakele: i-mine, ifektri, i-chimene noma i-blade. Qaphela ngokucophelela futhi sithombe sicacile kunezingxoxo.

NASA Glenn Research Center

Ngo-1979 NASA washintsha ku-Mod-1, i-wind turbine emibili-bladed ene-rotor engu-61 metres ngaphesheya, emfuleni eNorth Carolina. Yabe iyinye yezinto ezinamandla kakhulu zomoya ngesikhathi sayo futhi yabe yisinye sezimpi zokuqala zokuba amandla omoya athathe indawo ebalulekile kwi-grid. Iminyaka emihlanu ngemuva kwalokho, umoya kanye nelanga yizinto ezikhula ngokushesha kakhulu zomthombo wogesi emhlabeni. Ukukuqonda ukuthi kungani, nokuthi yini abakwazi ukuyikwenza, kusiza ukuqhathaniswa komthombo ngamunye ngemibandela efanayo.

Ukuphila konke, hhayi nje i-chiminea

Ukukhishwa kwe-power station akugcini nje ekamelweni lokushisa. Insimbi nekhonkrithi kumele yenziwe, igesi ikhishwe futhi ithunyelwe, futhi konke kufanele kususwa. Ukulinganisa kwempilo yokuphila kuhlanganisa konke lokhu ku-kilowatt-hour. Ukuhlolwa kwe-IPCC kwamakhulu emisebenzi yocwaningo inikeza ukubalwa okucacile: amakhoyili akhipha cishe 820 grams of CO2-equivalent per kilowatt-hour, igesi cishe 490, ngenkathi umoya, amandla kagesi kanye ne-hydropower ziphakathi kuka 10 kuya ku 25, futhi ilanga cishe 40 kuya ku 50.

Ukuphepha kutshela inkathi efanayo. Uma sibala izifo ezivela emiphumeleni yengozi kanye nokugqwala kwezulu ngeyunithi ngayinye yogesi, ikhoyili nepetroli yizinto ezibangelwa kakhulu ukulimala, ngoba ukudlidliza kuzo kwenza umoya ube nama-particles. Umoya, i-nuclear nelanga ziphephile izikhathi ezingaphezu kukamakhulu.
