- 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
- So, something that uses alternative fuels uses less gasoline than a regular something

- Electricity is a kind of alternative fuel
- An electrical device uses electricity to operate
- Hence, 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
- Hence, an electric motor uses alternative fuel to operate

- Something that uses alternative fuels uses less gasoline than a regular something
- An electric motor uses alternative fuel to operate
- Therefore, a something that uses an electric motor uses less gasoline than a regular something

- An electric car contains an electric motor
- An electric car is a kind of machine
- Therefore, an electric car is a kind of machine that contains an electric motor

- An electrical device can be a part of a machine
- If a machine contains a part then that machine uses that part
- Therefore, if a machine contains an electrical device then that machine uses that electrical device

- If a machine contains an electrical device then that machine uses that electrical device
- An electric motor is a kind of electrical device
- Therefore, if a machine contains an electric motor then that machine uses that electric motor

- An electric car is a kind of machine that contains an electric motor
- If a machine contains an electric motor then that machine uses that electric motor
- So, 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
- Hence, electric car uses less gasoline than a regular car

- Burning gasoline / oil is a source of air pollution
- Using a gasoline engine requires burning gasoline
- Therefore, 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
- Hence, 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
- Using less of something negative has a positive impact
- Therefore, using less gasoline has a positive impact on the environment / air quality / water quality / society

- Something that uses alternative fuels uses less gasoline than a regular something2
- Electric car uses less gasoline than a regular car
- Hence, an electric car has a positive impact on the environment / air quality / water quality / society by using less gasoline

Therefore, an electric car has a positive impact on the environment / air quality / water quality / society by using less gasoline
A car has a small gasoline engine combined with a battery-powered electric motor. When the car stops at a red light, the gasoline engine stops running and the electric motor begins working. How does this type of car most likely benefit people?
