Amanzi ayinsiza eyivelakancane yezigidi zabantu emhlabeni jikelele. Amaphampu amanzi kagesi asetshenziswa ezindaweni eziningi ukuthola amanzi angaphansi; lezi zinjini zamaphampu zikadizili zinikeza amandla azo. Kodwa-ke, lezi zinhlelo azidingi nje kuphela ukugcinwa okumba eqolo, okuqhubekayo nokuthengwa kukaphethiloli, kodwa futhi zikhulula i-carbon dioxide emkhathini owungcolisayo.

Okukhethwa kukho ukupompa amanzi elanga, okuvame ukwaziwa ngokuthi i-photovoltaic water pumping (PVP). Kuye kwaboniswa ukuthi iyasebenza, ngokwezimali, kanye nemvelo ngemva kweminyaka yocwaningo nokuthuthukiswa kobuchwepheshe. Intengo yobuchwepheshe belanga yehle kakhulu eminyakeni yamuva. Lezi zindleko zephaneli yelanga zehle zafika ku-80%. Lawa maphaneli nawo adinga ukunakekelwa okuncane kuyo yonke impilo yawo elinganiselwe yeminyaka engama-25.

Lezi zakhi zenze ukupompa amanzi elanga kwaba yisixazululo esiwusizo kakhulu sokwandisa ukufinyelela kwamandla emiphakathini nasezizweni ezisathuthuka kuyilapho kwakhiwa ukumelana okuqinile nezinguquko zemvula ezilethwa ukushintsha kwesimo sezulu noma amaphethini enkathi yonyaka angajwayelekile. Izindleko zokupompa ilanga zixhaswa ohulumeni abambalwa, okuye kwandise inqwaba yolwazi olwabiwe kulobu buchwepheshe obusha.

Siyakwamukela ukuthi usithinte ngohlelo lwakho lokunisela epulazini
