Uninzi lweendawo zokundwendwela zase-US ezizinzileyo nezincinci

Njengoko uxinzelelo lukhula kwizixeko kwihlabathi liphela ukuba zenze into yazo xa kufikwa ekulweni nokutshintsha kwemozulu, abahambi baya beqonda ngakumbi ifuthe abanokuba nalo kwiplanethi.

Uphononongo olutsha lwemizi-mveliso, olukhutshwe namhlanje, luhlalutye izixeko ezingama-50 ezityelelwe kakhulu eUnited States kuluhlu lwezinto ezifana nepesenti yeehotele ezizinzileyo, ukusetyenziswa kwezithuthi zikawonke-wonke, amanqanaba ongcoliseko, kunye namazinga okuxinana. 

Ke, zeziphi ezona ndawo zizinzileyo e-US? 

Ezona zixeko ziphezulu ezili-10 eziZinzileyo e-USA 

1. Portland, OR
2. Seattle, WA

4. Minneapolis, MN

10. Austin, TX

Kwindawo yokuqala Portland, Oregon, eyaziwa ngokuba sisixeko esinenkqubela. Ilizwe laseOregon linelona zinga liphezulu lokusetyenziswa kwamandla ahlaziyekayo kulo naliphi na kuluhlu lwethu (43.1%). Kwakhona, ifumana amanqaku aphezulu ngenxa yongcoliseko lokukhanya okuphantsi (6,590μcd/m2) kunye nenani leehotele ezizinzileyo (9% yeehotele zizonke). 

Akukude kakhulu ukusuka ePortland sisixeko esikwindawo yesibini eSeattle, eWashington. NjengePortland, iSeattle ifumana amanqaku aphezulu ngokusetyenziswa kwayo kwamandla avuselelekayo (38.4%) kunye nokungcoliseka komoya okuphakathi (6μg/m³), abantu abahamba okanye abasebenzisa izithuthi zikawonke-wonke (44.8%), kunye neehotele ezizinzileyo (9.19%).

Ngaphandle kokuba sesinye sezona zixeko zikhulu kwaye zixakekileyo emhlabeni, iNew York ithatha indawo yesithathu. I-NYC yayisisixeko esinamanqaku aphezulu hayi enye, hayi ezimbini, kodwa izinto ezintathu: iihotele ezizinzileyo, abantu abahambayo okanye abasebenzisa izithuthi zikawonke-wonke, kunye nobude beendlela zebhayisekile.

Uphando lukwaveze ezona zixeko zaseMelika zizinzileyo:

1. Nashville, TN
2. Columbus, OH
3. Dallas, TX
4. Houston, TX
5. Indianapolis, IN
6. Philadelphia, PA
7. Chicago, IL
8. Baltimore, MD

Ukuza ezantsi kuluhlu yiNashville, Tennessee, esinye sezixeko ezikhula ngokukhawuleza elizweni. I-Nashville sesona sixeko sinamanqaku aphantsi xa isiza kungcoliseko lomoya (14.3μg/m³) kwaye ikwafumana amanqaku alambathayo kwiziseko zophuhliso lwendlela yomjikelo, ene-0.6 yeemayile zeendlela ezikhuselweyo.

Isixeko sesibini esinamanqaku asezantsi yiColumbus, esona sixeko sinabantu abaninzi kwilizwana laseOhio. I-Ohio inomlinganiselo ophantsi kakhulu wokusetyenziswa kwamandla avuselelekayo (4.4%) kwaye isixeko saseColumbus sinezinga eliphezulu lokungcola komoya, kwi-13.6μg / m³.
