Cov nqi hluav taws xob ua lag luam tsis yog txiav txim los ntawm kev siv hluav taws xob ib leeg. Rau ntau qhov chaw, tus nqi kawg yog nyob ntawm seb siv pes tsawg kilowatt-teev (kWh) siv, qhov siab tshaj kilowatt (kW) xav tau sau tseg thaum lub sij hawm them nqi, thaum qhov kev thov ntawd tshwm sim, thiab cov nqi hluav taws xob tshwj xeeb siv rau lub xaib.
Tias yog vim li cas ib lub chaw tuaj yeem txo qis kev siv hluav taws xob txhua hli thiab tseem pom cov nqi siab tawv. Qhov kev thov luv luv tuaj yeem teeb tsa tus nqi thov rau lub hli, thaum lub sijhawm - ntawm - siv tus nqi tuaj yeem ua rau hluav taws xob siv ntawm ib teev kim dua li cov nyiaj siv tib yam ntawm lwm tus.
Qab-- 'meter' cia tuaj yeem pab tau qee qhov xwm txheej no, tab sis qhov pib qhov tseeb tsis yog roj teeb loj. Nws yog daim nqi, tus nqi se, thiab cov ntaub ntawv thauj khoom. US Department of Energy's Federal Energy Management Program ua rau tib qhov sib txawv hauv nws cov lus qhia txogntsuas qhov kev xaiv tus nqi siv hluav taws xob: Cov nqi hluav taws xob, cov nqi xav tau, thiab cov nqi tas li teb txawv rau cov kev hloov pauv hauv qhov chaw ua haujlwm.
Dab tsi ua rau Kev Lag Luam Hluav Taws Xob Sib Txawv?
Ib qho kev lag luam tariff yuav muaj ntau yam nqi tib lub sijhawm:
- Nqi zogRaws li kev siv hluav taws xob tag nrho hauv kWh.
- Xav tau nqiraws li qhov siab tshaj plaws lossis them nqi thov hauv kW.
