Lub rooj tsavxwm tswj lub zog tshiab muaj cov yam ntxwv ntawm kev sib koom ua ke siab, kev tswj xyuas ntse, kev tiv thaiv kev ua haujlwm, kev sib txuas lus, kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, kev ntseeg siab, kev nyab xeeb thiab kev saib xyuas yooj yim. Nws yog ib feem tseem ceeb ntawm cov khoom siv hluav taws xob tshiab. Nws cov kev xav tau kev ua haujlwm suav nrog kev tiv thaiv hluav taws xob, kev tiv thaiv tam sim no, kub tsis kam, av noo tsis kam, corrosion resistance, durability thiab lwm yam ntxwv los xyuas kom meej stability thiab kev cia siab ntawm cov khoom. Nyob rau tib lub sijhawm, cov tswj hwm lub zog tshiab kuj yuav tsum muaj peev xwm tiv thaiv kev cuam tshuam zoo.
Nws yog dav siv nyob rau hauv renewable zog, hluav taws xob tsheb, ntse daim phiaj thiab lwm yam teb. Nws yog ib qho ntawm cov thev naus laus zis tseem ceeb los ua kom tau txais txiaj ntsig zoo ntawm kev siv hluav taws xob tshiab thiab kev txuag hluav taws xob thiab txo qis emission los tiv thaiv cov chaw ua haujlwm nyuaj.
