Asian　economies　in　contrast　with　other　developing　economies　appear　to　be　the　lowest　in　competition　when　it　comes　to　achieving　sustainable　development.　The　reason　is　connected　with　energy　security　and　non-renewable　energy　as　these　are　one　of　the　key　issues　which　are　confronted　by　these　nations.　Therefore,　the　current　study　proclaims　to　investigate　the　crucial　factors　that　play　a　bigger　role　in　sustainable　development.　These　factors　are　measured　in　the　context　of　adjusted　net　savings　and　the　study　extracted　the　data　from　10　Asian　economies　covering　the　time　period　of　1990-2020.　The　study　adopted　panel　estimation,　slope　heterogeneity,　co-integration,　and　CS-ARDL　techniques　to　estimate　the　coefficient.　Whereas,　for　robust　analysis,　AMG　and　CCEMG　techniques　were　used.　The　findings　revealed　that　REW　energy,　economic　growth,　and　financial　development　altogether　enhance　adjusted　net　saving　and　reduce　non-REW　energy　consumption.　It　is　recommended　in　the　study　that　the　sample　countries　should　adopt　the　required　provisions　in　renewable　sectors.
