Pasina nguva refu yapfuura, yakaburitswa na REN21 (Renewable Energy Policy Network yezana ramakumi maviri nemasere, iyo 2017 edition yemushumo wepasirese nezve mamiriro ezvinhu emagetsi anovandudzwa munyika (Renewables 2017 Global Status Chirevo)).
REN21 inobatanidza hurumende dzakasiyana, NGOs, mayunivhesiti nemasangano epasi rose senge World Bank, International Energy Agency, United Nations, uye yakareba etcetera.
Simba rinowedzerwazve mushumo wepasi rose
Inotaura kuti mu2016 rekodhi nyowani yakaiswa maererano ne pasi rese magetsi magetsi inogona kudzoreredzwa pamwe huwandu hwe161 gigawatts. Iine nyika senge China kana India iri pamberi
Izvi zvinomiririra kuwedzera kweanoda kusvika 9% pamusoro pegore rapfuura, izvo zvinowedzera kune magetsi emagetsi ese e2.017 gigawatts pasi rese.
Kana isu tikasiyanisa pakati pesimba rakasiyana rinowedzerwazve, ndiyo Photovoltaic Solar Energy iyo inomira pamusoro pevamwe nezvine a 47% yesimba rakaisirwa simba, richiteverwa ne mhepo ine simba na a 34% and the hydraulics nechimwe chinhu chinopfuura 15%.
Remangwana rinouya
Chirevo chinowedzera akati wandei mibvunzo yakakosha maererano nekusanduka kweramangwana kwesimba rinowedzerwazve pasirese.
Mune dzimwe nyika dzakaita seDenmark, Mexico kana United Arab Emirates, mutengo wemagetsi kubva kunzvimbo dzinowanikwazve wakaiswa pa $ 0,1 / kWh, zvinoreva kuti chimiro chepasi kune iyo chizvarwa inodhura iyo yakawanda yakajairwa kumisikidza ine, uye zvakare, isina kana chero mhando yemari yepamberi.
Rekodhi muDubai kune inopisa zuva
Iyo Dubai Electricity neMvura Authority (Dewa) yakazivisa mavhiki mashoma apfuura mitengo yekubhidha yemabhizimusi mana ekubhadharisa kusimudzira kwe200-megawatt yechina chikamu cheMohammed bin Rashid Al Maktoum solar park. Bhii repashure rakatumirwa kune iri rakakwenenzverwa simba rezuva purojekiti iri 9,45 US cents (ingangoita 8.5 euro cents) pa kWh.
Uyu mutengo unomiririra rekodhi nyowani, nekuti yekutanga yaive 40% yakakwira kupfuura mutengo wakaderera wakapihwa kusvika parizvino. Zvimwe zviviri zvinopihwa vakapa zvakare mitengo yakaderera pa10 euro masendi kWh.
Iyo nyoro yechikamu chechina chepaki yezuva yeiyo thermosolar chirimwa ine tekinoroji tekinoroji inosanganisira kuchengetera magetsi kwemaawa anosvika gumi nemaviri, zvinoreva kuti ichi chinetso chinokwanisa kuenderera kugovera magetsi husiku hwese, uye ndicho chikamu chekutanga chebudiriro inoronga kuve ne1.000 MW yesimba rinopisa rezuva netekinoroji yeshongwe.
Nehurombo, kuSpain hatigone kutaura zvakafanana, semhedzisiro yekucheka kunoitwa kumagetsi ezuva anodziya magetsi.
Aya matanho emitengo anokurudzira nyika zhinji kuronga kuiswa kwezuva remagetsi emagetsi magetsi muSpain mushure memakore mazhinji pasina zvivakwa, Zvinotaridza sekunge izvo zvinodiwa neEU zvakare zvine hupenyu pamusika.
Uku kuchinjana kwakakosha kuti ubatanidze hunyanzvi hutsva hunopa kugona kwenetiweki uye kugadzikana kune mamwe matekinoroji sezviri pachena zvakachipa, havagone kupa.
Kune vazhinji vatungamiriri vemakambani ezuva, "solar thermal ndiyo yega inokwanisa kugadziriswa tekinoroji ine zvakanakira kugadzikana kwegridhi ine zviwanikwa zvinopfuura zvakakwana kuti kuvhara zvinodiwa zvemagetsi yenyika chero ine zuva rakajairika. Uye zvakare, mushure memazana emakore eR & D kuyedza, iyo tekinoroji yakura zvakanyanya, parizvino inogona kukwikwidza mumutengo nechero tekinoroji.
Denmark
Izvi zvakaitika, semuenzaniso, mu Denmark, nyika yakazara zvakakwana ine simba rakawanda rinoda.
Chirevo ichi zvakare chinosanganisira kuti mapurojekiti ekuchengetedza magetsi akaitwa kweanosvika 800 megawatts emagetsi akaisirwa, ayo anomiririra huwandu hwepasi rose hwegigawati 6,4.
Izvo zvakare zvinoratidza kuti zvakafanira kuita kuyedza mukushisa kwekushandisa kwezvinhu zvinowanikwazve kana mukushandisa kwavo mu chikamu chekufambisa, sezvo izvi zvisati zvagadzirwa zvakakwana kurwisa mafuta.
Kuchengeta nharaunda
Kukosha kwekushandiswa kwesimba rinowedzerwazve zviwanikwa kubva kune zvakatipoteredza maonero kunofanirwa kusimbiswa, kana chinangwa chiri chekuita nezvisungo zvepasirese pa kuchinja kwemamiriro ekunze, kunyanya ne Chibvumirano cheParis, uko avhareji tembiricha yekuwedzera yegore inongogumira pazasi pe2 ºC.
Gore negore, simba rakawanda riri kuiswa iro rinoshandisa zviwanikwa zvinowedzerwazve kupfuura zveyakajairika matekinoroji.
Izvi zvinofambidzana nekudiwa kwezvivakwa zvemagetsi senge kutapura uye kugovera netiweki, ruzivo uye masisitimu ekutaurirana, kuchengetedza magetsi, nezvimwe, saka mari ichaitwa mumakore anotevera ichave yakakwira kwazvo.
