Iyo US Environmental Protection Agency (EPA) nguva pfupi yadarika yakazivisa kuti haisi kuzobvisa iyo inosungirwa kuwedzera ethanol muUS Renewable Energy (RFS) standard. EPA yakati sarudzo, iyo yakaitwa mushure mekugamuchira zvirevo kubva kune vanopfuura zviuru zviviri nemazana mana akasiyana-siyana, yakaratidza kuti kudzima iyo inosungirwa kupihwa ethanol muyero kunogona kuderedza mitengo yechibage ne1 muzana chete. Kunyange hazvo hurongwa uhu hwave nenharo muUnited States, danho reEPA rinoreva kuti mamiriro ekumanikidzwa kuwedzera ethanol kupeturu akasimbiswa.
Pakutanga gore rino, magavhuna mapfumbamwe, maseneta makumi maviri nematanhatu, nhengo zana nemakumi mashanu dzeImba yeVamiriri veUS, uye vagadziri vazhinji vezvipfuyo nehuku, pamwe nevarimi vanodyisa chibage, vakadaidzira EPA kuti ibvise iyo inosungirwa yekuwedzera ethanol inotsanangurwa muchiyero cheRFS. . mazwi. Izvi zvinosanganisira kuwedzera kwe13.2 mabhiriyoni emarita echibage ethanol.
Ivo vakapomera kukwira kwemitengo yechibage pamusoro pekuti 45 muzana yechibage cheUS inoshandiswa kugadzira mafuta ethanol, uye nekuda kwekusanaya kwemvura kwechirimo ichi kwezhizha, kugadzirwa kwechibage kunotarisirwa kudonha nezvikamu gumi nezvitatu kubva gore rapfuura kusvika pakupera kwemakore gumi nematanhatu. . Mumakore matatu apfuura, mitengo yechibage yakada kukwira zvakapetwa kaviri, izvo zviri kuisa vanhu ava pasi pedambudziko remitengo. Saka vanonongedzera kuchiyero cheRFS, vachikakavara kuti kugadzirwa kwe ethanol kunodya chibage chakawandisa, kuchiwedzera kutyisidzira kwekusanaya kwemvura.
Miyero yeRFS chikamu chakakosha chehurongwa hwenyika hweUS hwekusimudzira kuvandudzwa kwebiofuel. Zvinoenderana nezviyero zveRFS, panosvika gore ra2022, US cellulosic ethanol kugadzirwa kwemafuta kuchasvika mabhiriyoni gumi nematanhatu emarita, kugadzirwa kwechibage cheethanol kuchasvika mabhiriyoni gumi nemashanu emarita, kugadzirwa kwebiodiesel kuchasvika bhiriyoni imwe, uye kugadzirwa kwebiofuel yepamusoro kuchasvika mabhiriyoni mana.
Chiyero chakashoropodzwa, kubva kumakambani echinyakare emafuta uye gasi, nezvemakwikwi ezviyo zviwanikwa, nezve data tarisiro inobatanidzwa muyero, zvichingodaro.
Aka ndekechipiri EPA ichikumbirwa kubvisa zvisungo zvine chekuita neRFS. Kubva muna 2008, Texas yakaronga kuEPA kuti ibvise zviyero zvine chekuita neRFS, asi EPA haina kuzvigamuchira. Nenzira imwecheteyo, EPA yakazivisa munaNovember 16 gore rino kuti haizorambi zvinodiwa kuti iwedzere 13.2 bhiriyoni marita echibage se feedstock ethanol.
EPA yakataura kuti pasi pemutemo panofanirwa kuve nehumbowo hwe "kukanganisa kwakanyanya kwehupfumi" kana zvisungo zvakakodzera zvichibviswa, asi mumamiriro ezvinhu aripo, chokwadi hachisvike padanho iri. “Tinoziva kuti kusanaya kwemvura kwegore rino kwakonzera matambudziko kune mamwe maindasitiri, zvikuru ekupfuya zvipfuyo, asi ongororo yatakaita inoratidza kuti zvinodiwa nedare reCongress kuti zvibviswe hazvisati zvazadzikiswa,” akadaro EPA Office Assistant Administrator, Gina McCarthy. Zvinodiwa zvezvipimo zvakakodzera, kunyangwe zvipimo zvakakodzera zveRFS zvikabviswa, zvichave nemhedzisiro shoma. "
Pakangoziviswa sarudzo yeEPA, yakabva yatsigirwa zvakasimba nemapato akakodzera muindasitiri iyi. Brooke Coleman, mukuru mukuru weAdvanced Ethanol Council (AEC), akati: “Indasitiri ye ethanol inoonga maitiro eEPA, nekuti kubvisa RFS hakuzoite zvishoma kuderedza mitengo yezvokudya, asi kuchakanganisa mari yemafuta emhando yepamusoro. RFS yakanyatsogadzirwa uye Chikonzero chikuru chekugadzirwa kwemafuta emagetsi epamusoro muUnited States ndiye mutungamiri wepasi rose. Vagadziri vekuAmerica vanogadzira ethanol vachaenda vese kupa vatengi sarudzo dzakasvibira uye dzakachipa.
Kune avhareji yekuAmerica, sarudzo yazvino yeEPA inogona kuvachengetera mari sezvo kuwedzera ethanol kunobatsira kudzikisa mitengo yepeturu. Maererano neongororo yaMay yakaitwa nenyanzvi dzezvehupfumi kuWisconsin neIowa State Universities, kuwedzera ethanol kwakadzikisa mitengo yepeturu ne$1.09 pagaloni muna 2011, nokudaro zvichideredza avhareji yemba yekuAmerica kushandisa peturu nemadhora chiuru nemazana maviri.
