Sidinga umhlaba omningi ukuze sihlangabezane nezinhloso zawo zamandla avuselelekayo, kodwa abanye abalimi bayaphikisana nokungenwa kwamapulazi elanga endaweni okuhloswe ngayo ukutshala ukudla.
UMnyango Wezamandla ukholelwa ukuthi “ilanga linganikeza ugesi ofinyelela ku-40% wezwe ngonyaka ka-2035. Nokho, kulinganiselwa ukuthi cishe umhlaba ongamahektha ayizigidi ezingu-5.7 uzodingeka,”imibikoUClinton Griffiths weFarm Journal.
UMat O'Neal, uprofesa e-Iowa State University kanye noSihlalo weWallace for Sustainable Agriculture, utshele uGriffiths: “Kungase kudingeke izigidi zamahektare ukuze kukhiqizwe amandla elanga eminyakeni engu-20 kuya kwengama-30 ezayo kanti omunye walowo mhlaba, hhayi wonke. kungaba indawo yokulima.Lokho kuyabakhathaza abanye abantu, ikakhulukazi labo balimi baseMidwest.”
Kulapho-ke umsebenzi we-agrivoltaics ungena khona.Isiyalo silwela ukukhombisa ukuthi ukulima kanye nelanga kungaphilisana kanjani.
UStephanie Mercier, ongumeluleki wenqubomgomo yezolimo, utshele uGriffiths, “Lolu cwaningo lwaqalwa ngo-1981 ngososayensi ababili baseJalimane, u-Adolph Goetzberger kanye no-Armin Zastrow, abanquma ukuthi kwakhiwe amaphaneli elanga ukuze aphakame cishe ngamamitha ayi-6 ngaphezu komhlaba. ezibekwe ngqo phansi zingavumela izitshalo ukuba zilinywe ngaphansi kwe-solar panel.”
I-Agrivoltaics yintsha kubalimi bezitshalo base-US, kodwa i-DOE isebenzela ukubasiza baqonde futhi basebenzise lo mkhuba ngokusekela ucwaningo.I-Iowa State University ithole isibonelelo sika-$1.8 million se-DOE ukuhlola "amathuba okukhulisa izithelo nemifino ngaphansi kwalawo maphaneli e-solar photovoltaic," kubika uGriffiths.U-O'Neal wamtshela: “Leso simo esinomthunzi singase sihle kwezinye zalezo zitshalo, futhi mhlawumbe sichume size siphumelele kwezomnotho.Okwamanje asikazi, futhi inhloso yocwaningo lokho.”
“UMercier uthole ukuthi izilinganiso zakamuva zikhomba ukuthi njengamanje kunezindawo ze-agrivoltaics ezingaphezu kuka-340 e-US, ikakhulukazi ezihlanganisa i-solar nezindawo ezihlala impova noma amadlelo amancane, njengezimvu, kumahektha angaphezu kuka-33,000 ngenkathi ikhiqiza isamba samagigawathi angu-4.8 wamandla elanga. ,” kubika uGriffiths.
"UMercier wengeza ngokusho kwenhlangano yocwaningo yaseJalimane, iFraunhofer ISE, ngo-2022, imiphumela yokuqala yephrojekthi ezweni elisenyakatho ne-Afrika i-Algeria yathola ukuthi ngaphansi kokufakwa kwe-agrivoltaic kwaba nokwanda kwesivuno samazambane cishe ngo-16% uma kuqhathaniswa nensimu engamboziwe. .”
