Harmful effects of Hybrid cars

Hybrids are not emission free – There is a reduction in the emissions compared to no hybrid cars, however, make no mistake, hybrid cars still adds to the pollution in the environment.

Battery Pack – The main effect of hybrid cars on the environment is the battery. Nickel metal hydrides are used in these batteries. Rare earth metals such as neodymium are also used in addition to extra wiring and electrical components. Mining these metals cause harm to the ecology and the environment. If proper recycling or disposal of the battery is not done, it could cause harm to the environment in the future.

The Controversy

Hybrid cars:

Pros:

Engine turns off when idle

Reduces smog emissions

Gas motor charges the batteries while it's running

Cons:

Complex and expensive

Frequent expensive repairs and replacements required

Flow of high electric currents can prove to be dangerous

Non Hybrid cars:

Pros:

Less Expensive

No mining of rare earth metals

No harmful exposure to materials like lithium or nickel

Cons:

More fuel consumption

More smog emissions

Working of a Hybrid Car

A hybrid car is a vehicle which has two or more types of engines - such as a regular combustion engine in combination with an electric motor.

It also has a regenerative system to capture braking energy to store in an onboard battery.

The combustion engine is generally used for higher speeds on the highway, while the electric engine is used in lower speeds, in urban areas.

Other Effects on Humans

Pedestrians – Hybrid cars make less noise, which makes it difficult for pedestrians and especially visually impaired individuals to hear them while crossing street.

Electromagnetic field – The electromagnetic fields generated at lower driving speeds can be harmful to humans. Studies have linked exposure to electromagnetic fields with risk of leukemia in children

Lighter weight– Hybrid cars are...
