SLTbelievesthatabilitiestochangeenergyefficiencyaredifferentineachsegmentofthecommunity.Programsneedtobedesignedtounderstandthestrengthsandweaknessofthetargetgroup.Forexample:

All-electricvehicleshavebeencommerciallyavailableforsometime,andanumberarealreadyonTasmanianroads,includingintheUniversityofTasmaniafleet.Peoplewon’tpurchaseall-electricvehiclesuntilthereissufficientcharginginfrastructure,butbusinesseswon’tbuildcharginginfrastructureuntilthereissufficientmarkettoensureareturnoninvestment.InAustralia,Tasmaniaisinauniquepositionduetotherelativelyshortdistancesbetweenpopulationcentres,meaningfewerchargingstationsarerequiredtoachievegoodcoverage.Withtherightmixofstakeholders,SLTbelievesatourism-ledventurecankick-startthevehicleelectrificationinTasmania.

4.3.2RenewableEnergy
SLTwouldliketoseeTasmaniaas100%renewableinitsenergyuseforstationaryandtransportenergy.Tasmaniaiswellplacedtoachievethis. SLTalsobelievesthattheglobalenergytrajectoryisheadingtowardsdistributedrenewableenergyandstoragesystems.
