Lolu shintsho kuthrendi ngokwezindleko Sekuqalile ukukhombisa. Ngo-2016, kwafakwa amandla angaphezulu kwangu-9%, esikhundleni se- Ama-23% angaphansi konyaka owedlule emandleni avuselelekayo.
Eminyakeni yakamuva, ukuthuthuka kwezobuchwepheshe kube nomthelela omkhulu kwi ukuncishiswa kwemali edingekayo ukwethula amaphrojekthi amasha angavuseleleka. Umoya nelanga i-photovoltaic kube yiyona ezuzwe kakhulu yilezi 'izaphulelo', ngenxa yemisha emisha (njengama-turbines omoya omoya ophindwe kabili), evumele Thola amandla amaningi 'aluhlaza' ngokuncane kakhulu.
Eqinisweni, ngo-2016 utshale imali encane ezindaweni yalolu hlobo emhlabeni wonke kunango-2015 (ingqikithi yama-euro ayizigidi ezingama-227.575, amele ukwehla kwama-23%) kanti, nokho, yengezwa amandla avuselelekayo kunanoma yimuphi omunye unyaka owedlule onamarekhodi (138,5 GW, 9% ngaphezulu kunango-2015), ngokusho kwedatha evela embikweni owalungiswa yi-UN, iFrankfurt School of Finance & Management neBloomberg.
Olunye ucwaningo, olusayinwe yi-UN, luqinisekisa ukuthi le ndlela 'enhle' eyehlayo yamanani kagesi ahlanzekile izoqhubeka eminyakeni ezayo nokuthi, eminyakeni eyishumi nje, Kuzoba kushibhile ukugembula kuzo kunanoma yiluphi olunye uhlobo lomthombo emhlabeni.
Umehluko omkhulu
Kodwa-ke, lokhu akusho ukuthi 'imfiva eluhlaza / inguquko evuselelekayo' ithelela yonke iplanethi. Umbiko uphawula ukuthi izimakethe ezisafufusa - njengeNdiya noma amazwe amaningi ase-Afrika - kungenzeka kakhulu bagxile ekukhuleni kwezomnotho kangangoba bahlose kuphela ukuhlinzeka zonke izidingo zabo zamandla ngokushesha okukhulu, ngaphandle kokuma bacabange kabili ukuthi bayakwenza noma cha ngokwenza okuvuselelekayo noma uma ukukhetha kwabo kulo mkhakha kuzoba nomthelela omubi emvelweni.
I-UN ibuye ibheke ukuthi kuzoba nokwehluka okumbalwa phakathi kweYurophu ne-Australia, okugxilwe ngokuphelele emithonjeni 'ehlanzekile nevuselelekayo', kanye ne-US neJapan, ngaphezulu "engafuni".
Endabeni yelanga eliphumayo, inkinga enkulu isikhala, ngoba sinendawo encane yokufaka izitshalo zomoya noma zelanga futhi, okungenani, ukufaka izitshalo ezinamandla kagesi kagesi. Ngaphezu kwalokho, uphenyo luthi, akunakwenzeka ukuthi imboni yamandla 'yendabuko' yaseJapan ithathe isinqumo sokuxhasa u-'luhlaza 'ocija i-bat. Empeleni isisombululo esingaba khona enkingeni yesikhala, ukufakwa kwamaphaneli elanga antantayo, sizokhuluma ngabo ekugcineni kwendatshana.
I-United States vs ivuselelwa
Izwe laseMelika nalo linenkinga yendawo yokwamukela izivakashi embonini yendabuko nezinto zokwenziwa kwezinto ezimbiwa phansi, ezithuthukisiwe, namuhla, ngumbono weqembu eliphethe amandla. yenze impi ethile evuselelekayo ”.
Ngokwengxenye yayo, iChina, yize iphila esimweni esifana naleso seNdiya ngokomnotho wayo okhulayo kanye nenani elikhulu labantu ngokunyuka njalo, uthathe isinqumo sokwenza umehluko, ukubheja kwinethiwekhi yamandla 'ehlanzayo' bese uhamba kude, ngangokunokwenzeka, kusuka kumandla okubasa.
Amapaneli welanga antantayo
Kusukela ngo-2011 inkampani yaseFrance iCiel & Terre ibisebenza ukudala amaphaneli amakhulu elanga antantayo. Uhlelo lwayo, olubizwa nge-Hydrelio Floating PV luyavuma amaphaneli ajwayelekile elanga afakwa ngaphezulu kwamanzi amakhulu njengamachibi, amadamu neziteshi zamanzi zokunisela nokunye okunjalo, kanye namadamu okukhiqizwa kwamandla kagesi we-photovoltaic. Imayelana nokwakha enye indlela elula futhi engabizi kakhulu emapaki elanga asemhlabeni, ikakhulukazi ngokucabanga ngezimboni ezisebenzisa izindawo ezinkulu zamanzi nokuthi akudingeki bayeke ukubanikeza ukusetshenziswa okuningi.
Ngokusho kwenkampani, kulula ukuyihlanganisa nokuyiqaqa, ingashintshelwa ekulungisweni kukagesi okuhlukile, iyasabazeka futhi ayidingi imishini esindayo noma amathuluzi. Izakhiwo zokuqala zalolu hlobo zakhiwe e-United Kingdom naseJapan.
Ama-turbine omoya ama-rotor aphindwe kabili
Ngokusho konjiniyela u-Anupam Sharma noHui Hu, we-Iowa Energy Center, isisekelo sophehla ugesi sinezinkinga ezimbili ezinkulu ezinciphisa ukusebenza kwazo kahle: eyodwa, ukuthi ziyizingcezu ezinkulu eziyindilinga ezingazenzi amandla ngokwazo, kanti eyesibili, ukuthi zibangela a ukuphazamiseka emoyeni okubuye kunciphise amandla kwanoma iyiphi i-generator etholakala ngemuva kwabo phakathi kuka-8 no-40% kuye ngezimo.
Isixazululo sakho sithi engeza i-rotor yesibili, incane, kumshini ngamunye ophendulwa ngamanzi. Ngokuya ngokulinganisa kwabo kanye nokuhlolwa okwenziwe emihubheni yomoya, ama-blade angeziwe akhulisa amandla akhiqizwa kufika ku-18%. Icebo lokwenza i-turbine nge Rotor kabili esebenza kahle ngangokunokwenzeka, Ukunquma ukuthi iyiphi indawo engcono yokubeka eyesibili, ukuthi kufanele ibe nkulu kangakanani, isisekelo sayo kufanele sibe siphi isimo futhi uma kufanele ijikeleze ngendlela efanayo ne-Rotor main, noma okuphambene nalokho.
Inkinga isukela manje kuze kube yileso sikhathi.
