Are Electric Cars Really Better For The Environment?

And what’s so bad about petrol and diesel anyway?

Pollutants

Have you ever wondered why there’s no exhaust on electric vehicles? 

The exhaust acts as a channel for the toxic gasses to leave the engine and enter the atmosphere, these gasses include Carbon Dioxide, Nitrogen Oxide and Nitrogen Monoxide. These gasses are created through the burning of fossil fuels and come from more than just cars. They also come from:

  • Natural sources (Volcanos and lightning)
  • Other mobile sources (Busses, motorcycles, airoplanes etc.)
  • Livestock 
  • Factories, power plants, sewage treatment centres etc.

As there is no exhaust on electric vehicles, there are no harmful gasses leaving the engine (zero emissions). Electric vehicles to not depend on an ignition to drive, like petrol and diesel, they run purely on an electric motor powered by the battery that turns the wheels. This however means that the only pollution produced by your vehicle is the amount created when charging your batteries. But, it’s a lot less when compared to the amount produced by petrol/diesel vehicles.

Why Are Electric Cars Better for The Environment?

Air Quality

The gasses produced by petrol and diesel engines are harmful to humans, they can help worsen or cause asthma and contribute to the development of multiple respiratory and cardio-vascular illnesses and diseases. Electric vehicles are helping to keep the air cleaner for people and animals on Earth, especially in places such as cities where the pollution can be the worst. 

Energy Regeneration

Some electric vehicles now have ways of replenishing charge back into your battery when driving and stopping, this then prevents you from burning fossil fuels to charge your battery back up. Although currently a small amount is replaced, constantly advancing technology could see a change to this in future years to come.

Water Pollution 

When toxic emissions are released into the atmosphere they can mix and react with water and oxygen to create clouds that drop acid rain, the acid can fall into water supplies and even travel through soil. This can kill water life, plants and even animals with habitats around the water. 

Global Warming

Carbon Dioxide, and other greenhouse gasses, trap heat in the Earth’s atmosphere causing a worldwide temperature rise (global warming), a global temperature increase of 0.9 degrees celcius has been slowly amplifying the melting rate in the North and South poles since 1906.

Melting ice has led to the deaths of wild species such as polar bears and penguins due to their homes vanishing, as well as this, the global sea levels are rising and are increasing in speed year by year.
