Amandla ahlaziyekayo abonwa ngabapolitiki abaninzi. Inkxalabo ngemeko-bume ikhulile kumaxesha akutshanje kubemi behlabathi Kodwa iingcali zinethemba: ukusetyenziswa kwamandla acocekileyo kuya kunyuka kule minyaka izayo (Ingakumbi amazwe anjenge China ne India).
I-Arhente yaMandla yeHlabathi (i-IEA) ibona kwangaphambili ukuba amandla ahlaziyekayo aya kuqhubeka ingoyena mthombo ukhula ngokukhawuleza wokuvelisa umbane kule minyaka mihlanu izayo, isuka ekumeleni i-23% yesizukulwana ngo-2015 kuye ku Iipesenti ezingama-28 ngo-2021.
NgoFebruwari ophelileyo, ngexesha lokunikezelwa kwesifundo se-IEA 'seNgxelo yeXesha eliPhakathi leMandla aVuselelekayo ka-2016' esiququzelelwe yiKlabhu yaMandla eSpain (i-Enerclub), intloko yecandelo lamandla ahlaziyekayo learhente yamanye amazwe, uPaolo Grankl, wagxininisa ukuba ukuphinda kusebenze kuya kuthetha ngaphezulu kwe-60% yolwando kwisizukulwana sehlabathi yombane kwixesha eliphakathi.
Kwangokunjalo, igosa eliphezulu le-IEA lachaza ukuba kulindeleke Amandla ahlaziyiweyo kwihlabathi liphela okunyusa nge-825 gigawatts (GW), eyi-42% phakathi kowama-2015 nowama-2021. Ukongeza, ubonakalisile ukuba kuqikelelwa ukuba ukuveliswa kwezinto ezihlaziyiweyo kuya kudlula iiyure ezingama-7.600 zeterawatt (TWh) kwiminyaka emine, elingana nokuveliswa kombane xa zizonke I-United States kunye ne-European Union.
Kodwa ngaphandle kwale mibono, uFrankl wayenjalo ilumke malunga nokuvela kwayo ngenxa yezinto njenge ukungaqiniseki kwezopolitiko, ukudityaniswa kwayo okukhulu kwiinkqubo, isidingo sotyalo-mali ngakumbi okanye ukukhula kancinci kwetekhnoloji ehlaziyekayo kumacandelo obushushu kunye nezothutho.
UTrump akasayi kuba kwimeko
UPaolo Frankl ukwathe wathetha ngemeko yaseMelika. Ingcali ichaze ukuba ayikholelwa ukuba ukhetho lwe UDonald Trump njengomongameli welizwe laseMntla Melika iyakubeka kwimeko yokukhula kwamandla ahlaziyekayo kolo hlanga, ekulindelwe, ukuba ligqithe kumthamo ofakiweyo weYurophu kwisithuba seminyaka emihlanu.
Ukongeza, intloko yeqela le-IEA lokuphinda lihlaziyeke lalinethemba, kuqatshelwa imigaqo-nkqubo "Azinakuguqulwa ukusuka kolunye usuku luye kolulandelayo", Umbutho ulindele ukuba kungabikho zitshintsho zininzi kwiinyanga ezizayo.
Ngokubhekisele eSpain, uFrankl wakhankanya ngexesha lokunikezelwa kwengxelo malunga neendlela zentengiso yamandla ukuba ifandesi yexesha elizayo yamandla ahlaziyekayo inokuthi "Yenza utshintsho" kuqikelelo lwe-IEA. Ngale ndlela, intengiso yesizwe inokushiya indawo yokudodobala kwezoqoqosho ukusukela kule minyaka ilishumi idlulileyo.
Ukongeza, ngengxelo yayo, i-IEA ilumkisile IPoland ukuba kufanele ukunciphisa ukusetyenziswa kwamalahle kumxube wayo wamandla kwaye utshintshe isicwangciso-qhinga sokwandisa imithombo kunye nokukhutshwa okuphantsi kwe-CO2, ezinje ngezixhobo zenyukliya okanye ezivuselelekayo, ukusukela «amalahle abonelela ngama-51% kunikezelo lwamandla elizwe, ngokweenkcukacha zango-2015 ″.
Eyona injini yomoya inkulu ehlabathini
Iinjini zomoya ezinje ngezi zinoxanduva lokunyusa amandla ehlabathi
IVestas ivelise uhlaziyo lwenjini enkulu yomoya emhlabeni. Andinazo izichazi zokuchaza ukuba inkulu kangakanani le injini. I-V164, i-220 yemitha yomoya kunye ne Iitoni ezingama-38, iimitha ezingama-80 ubudeIjongise nje yonke ingqalelo yabo banomdla wokuvuselelwa eDenmark.
I-turbine yangaphambili ibinakho ukuhambisa amandla e-8 MW, kwaye ngenxa yohlaziyo ngoku iyakwazi ukufikelela ukuya kuthi ga I-9 MW imveliso phantsi kweemeko ezithile. Kuvavanyo lwayo lokuqala, i-V164 yayi Iyakwazi ukuvelisa i-216.000 kWh ngeeyure ezingama-24 kuphela.
Ayisiyo kuphela irekhodi elipheleleyo lokuveliswa kwamandla omoya ngesixhobo somoya esinye, kodwa yi umboniso ocacileyo wokuba imimoya yolwandle iza kudlala indima ebalulekileyo kutshintsho lwamandla esele luqhubeka.
Kwanele ukuphatha ikhaya iminyaka engama-66
NgokukaTorben UHvid Larsen, IVestas CTO:
"Wethu prototype isete enye irekhodi lesizukulwana, nge 216.000 kWh eveliswe kwisithuba seeyure ezingama-24. Siqinisekile ukuba le turbine yomoya eyi-9 MW ibonakalise ukuba ikulungele ukuthengisa, kwaye sikholelwa ekubeni izakudlala indima ebalulekileyo ekwehliseni amaxabiso omoya aselunxwemeni. "
