Simba rinowedzerwazve riri mumaonero evazhinji vezvematongerwo enyika. Kunetsekana kwenharaunda kwakakura munguva dzichangopfuura pakati pevagari venyika, asi nyanzvi dzine tarisiro: kushandiswa kwesimba rakachena kuchawedzera mumakore anotevera (kunyanya nyika dzakaita seChina neIndia).
Sangano reInternational Energy Agency (IEA) rinoona kuti simba rinowedzerwazve richaenderera mberi kuve inokurumidza kukura sosi yekugadzirwa kwemagetsi mumakore mashanu anotevera, kuenda kubva kunomiririra 23% yechizvarwa muna 2015 kusvika a 28% muna 2021.
Nyamavhuvhu apfuura, panguva yekuratidzwa kwechidzidzo cheIEA 'Medium-Term Renewable Energy Market Report 2016' chakarongedzwa neSpanish Energy Club (Enerclub), mukuru wesangano rinowedzerwazve remagetsi pasangano repasirese, Paolo Grankl, akasimbisa kuti kudzoreredzwa kuchareva zvinopfuura makumi matanhatu kubva muzana zvekuwedzera kwechizvarwa chenyika yemagetsi munguva yepakati.
Saizvozvo, mukuru weIEA mukuru akatsanangura kuti zvinotarisirwa iro simba repasi rose rinogona kudzorerwa rinowedzera ne825 gigawatts (GW), inomiririra 42% pakati pemakore 2015 na2021. Uye zvakare, akataura kuti zvinofungidzirwa kuti kuburitswa kwezvinhu zvinowedzerwazve kuchapfuura maawa mazana manomwe nemazana matanhatu eterawatt (TWh) mumakore mana, zvinoenzana nezera rese remagetsi United States uye European Union.
Asi zvisinei nemaonero aya, Frankl aive inochenjerera maererano nekushanduka kwayo nekuda kwezvinhu s kusagadzikana kwezvematongerwo enyika, kusangana kwayo kukuru mumasisitimu, kudiwa kwekudyara kwakawanda kana kunonoka kusimudzira kweanowedzeredzwa matekinoroji munzvimbo dzekupisa uye dzekufambisa.
Trump haigadzike
Paolo Frankl akataura zvakare nezve mamiriro ezvinhu muUnited States. Nyanzvi yakaratidza kuti haitendi kuti sarudzo ye VaDonald Trump semutungamiri wenyika yeNorth America ichagadzirisa kukura kwesimba rinowedzerwazve murudzi irworwo izvo, zvinotarisirwa, zvichapfuura kugona kwakamiswa kweEurope munguva yemakore mashanu.
Uye zvakare, mukuru weIEA's unowedzerwazve kupatsanura aive netariro, achiona kuti marongero "Hazvigone kuchinjwa kubva kune rimwe zuva kuenda kune rinotevera", saka sangano rinotarisira kuti hakuzove ne "shanduko huru" mumwedzi iri kuuya.
Nezve Spain, Frankl akataura panguva yekuburitswa kweshumo pamusoro pemaitiro emusika wesimba kuti auction yeramangwana yesimba rinowedzerwazve inogona "Chikonzero shanduko" mune fungidziro yeIEA. Nenzira iyi, musika wepasi rose unogona kubva munzvimbo yekushomeka kwezvemari kubva makore gumi apfuura.
Uye zvakare, kuburikidza neshumo yaro, iyo IEA yakayambira Poland kuti inofanira kudzikisa kushandiswa kwemarasha mune yayo simba musanganiswa uye shandura zano rayo rekuwedzera masosi neakaderera CO2 emweya, senge yenyukireya kana anovandudzwa, kubvira «marasha anopa 51% yenyika inopa magetsi, maererano nedata ra2015 ″.
Turbine yemhepo yakakura kwazvo pasi rese
Mhepo turbine senge aya ane basa rekuwedzera simba repasirese simba
Vestas yakaratidza kudzoreredzwa kweiyo huru mhepo turbine mupasi. Handina zvipikisheni zvekutsanangura kukura kwakaita turbine iyi. Iyo V164, yemamirimita makumi maviri nemaviri yemhepo ine 38-tani, 80-mita refu mashizha, ingo tarisa kutarisisa kwese kwevaya vanofarira kumutsidzirwa muDenmark.
Iyo turbine yapfuura yaikwanisa kuendesa simba re8 MW, uye nekuda kwekuvandudzwa kwazvino rave kukwanisa kusvika 9 MW kuburitsa pasi pemamiriro chaiwo. Mune bvunzo yayo yekutanga, iyo V164 yaive inokwanisa kugadzira 216.000 kWh mumaawa makumi maviri nemana chete.
Haisi chete iro rekodhi rakazara rekugadzira simba remhepo nemhepo turbine imwe chete, asi ndiyo chiratidziro chakajeka chekuti mhepo dzegungwa chichaita basa rakakosha mukuchinja kwesimba kuri kutoenderera.
Zvakwana kugonesa imba kwemakore makumi matanhatu nematanhatu
Sekureva kwaTorben Hvid larsen, Vestas CTO:
"Wedu prototype yakaisa imwe chizvarwa rekodhi, iine 216.000 kWh inogadzirwa mumaawa makumi maviri nemana. "Tine chivimbo chekuti turbine yemhepo iyi 24 MW yakaratidza kuve yakagadzirira musika, uye tinotenda kuti ichaita basa rakakosha mukuderedza mitengo yemagetsi ekunze."
