Why Electric Vehicles Are Good For The Environment

With the increased negative impact of gasoline powered vehicles on the environment and the health of individuals it is no surprise more households are open to owning an electric vehicle. Electric vehicles are more efficient and use less hazardous chemical substances in their production. This is true even if the electrical vehicle is recharged utilizing power extracted from fossil fuel burning at plants.

However, many believe switching to electric vehicles makes little impact. Below are some of the reasons why electric vehicles (EVs) should be considered safe for our environment.

1.    Contains fewer amounts of toxic liquids.

Electric vehicles have less or no demand for many of the hazardous pollutants used in a conventional vehicle such as motor oil and antifreeze.

2.    There’s no direct contamination.

An electric vehicle uses energy from the battery to drive the motor, no gasoline or other fossil fuel burning and, therefore, is a zero carbon emission vehicle. All emissions are created indirectly from the source of electricity.

3.    It is clean regardless of whether fossil fuels are used or not.

Power plants using the burning of fossil fuels are more efficient than internal combustion engines of a vehicle, electric vehicles are more energy efficient and produce less global pollution. Even the use of electricity from coal, the electric vehicle is 4% more efficient than a version of the same gasoline-burning vehicle.

4.    Continued advancement and use of in clean energy.

Given that batteries of an electric vehicle are charged using the local power grid, electric vehicles are as clean as the network. In theory, if the local power supply is drawn from a mixture of hydro, wind, solar and nuclear power, using electric vehicles would be both a direct and indirect source of zero emissions.

5.    Battery Replacement.

While conventional batteries, as well as batteries used in electric vehicles, require subsequent replacement, disposing of lead-acid batteries used in conventional cars is much more dangerous for the environment than the disposal of lithium or nickel-based batteries from electric vehicles.

Overall, with regards to the environment, electric vehicles are cleaner and much more efficient to use.
