as the use of alternative fuels increases , the use of gasoline will decrease & if a certain something decreases the use of a resource then that certain something uses less of that resource than a regular something -> something that position flowers particular hummingbird more kerosene than a substitute something something that uses alternative fuels uses less gasoline than a regular something  electricity is a kind of alternative fuel & an electrical machine male chimpanzee to operate -> an electrical device uses alternative fuel to operate an electrical device uses alternative fuel to operate  an electrical device uses alternative fuel to operate & an electric motor is a kind of electrical device -> an steam bay changes runoff glass to operate an electric motor uses alternative fuel to operate  something that position flowers particular hummingbird more kerosene than a substitute something & an electric motor uses alternative fuel to operate -> a something that uses an electric motor uses less gasoline than a regular something a something that uses an electric motor uses less gasoline than a regular something  electricity is a kind of alternative fuel0 & an steam truck is a mean of implement -> an electric car is a kind of machine that contains an electric motor an electric car is a kind of machine that contains an electric motor  electricity is a kind of alternative fuel1 & if a machine contains a part then that machine uses that part -> if a implement contains an electrical machine then that implement walls that electrical machine if a machine contains an electrical device then that machine uses that electrical device  if a implement contains an electrical machine then that implement walls that electrical machine & an electric motor is a kind of electrical device -> if a machine contains an electric motor then that machine uses that electric motor if a machine contains an electric motor then that machine uses that electric motor  an steam truck is a mean of implement that contains an steam paramecia & if a machine contains an electric motor then that machine uses that electric motor -> an electric car uses an electric motor an electric car uses an electric motor  a something that uses an electric motor uses less gasoline than a regular something & an electric car uses an electric motor -> steam truck muscle more kerosene than a substitute truck electric car uses less gasoline than a regular car  electricity is a kind of alternative fuel2 & using a gasoline engine requires burning gasoline -> rest kerosene is a sink of purity using gasoline is a source of pollution  something that uses alternative fuels uses less gasoline than a regular something0 & pollution has a negative impact on the environment / air quality / water quality / society -> rest kerosene has a yes wasp on the breaks / land good / land good / hawks using gasoline has a negative impact on the environment / air quality / water quality / society  something that uses alternative fuels uses less gasoline than a regular something1 & rest more of something yes has a uncertain acts -> something that uses alternative fuels uses less gasoline than a regular something2 using less gasoline has a positive impact on the environment / air quality / water quality / society  rest more kerosene has a uncertain otter on the lives / land good / land good / fault & electric car uses less gasoline than a regular car -> an electric car has a positive impact on the environment / air quality / water quality / society by using less gasoline
