Are electric cars really eco-friendly?
Electric-car drivers are saving the planet, right? Their vehicles produce none of the pollutants that dinosaur-burning, fossil-fuel-powered machines do. That is the standard view, and governments around the world provide incentives to encourage the uptake of this new technology.
That is why a Tesla owner got a rude shock when he went to import his vehicle into Singapore - the first person to do so. The Tesla Model S is a 100% electric vehicle. It does not have an exhaust to emit from. So what happened?
Instead of an expected rebate of around S$15,000 (US$10,800) he received a fine of the same amount for being a gross polluter. The company commented the incident, "The Model S that our customer imported into Singapore left our factory only two years ago with energy consumption rated at 181 Wh/km. This qualifies as the cleanest possible category of car in Singapore and entitles the owner to an incentive rather than a fine."
The Singapore authorities calculated the ‘carbon cost’ of generating the electricity that will be used to charge the car. This is the elephant in the trunk of electric vehicles. Where and how the power is produced is not often considered, but perhaps it should be. Let’s move the elephant up to the passenger seat and address it directly.
The authorities in Singapore apparently found the Tesla in question consumes 444 watt-hours of electricity per km (Wh/km) in tests. Without wanting to get too maths-heavy, the number of 444Wh/km does seem high. And as we still need power stations to produce such amount electric energy, the environmental impact is not so small as it seemed to be.
But what about the bigger picture - should we be factoring in the emissions of power stations when working out how green an electric car is? The logical answer is yes. Emissions shifted elsewhere are still emissions, and CO2 impacts the global atmosphere wherever it is released.
Now let’s look at the questions:
What is the aim of this text?
A) To discourage people from visiting Singapore
B) To prove that electric cars are less eco-friendly than fossil-fuel-powered machines
C) To show that we need to count the emissions of power stations to see how green an electric car is.
When the owner of the electric car went to Singapore, he received
A) a rebate of around US$10,800
B) a fine of around US$10,800
C) a fine of around US$15,000
To prove that electric car was a gross polluter, the authorities in Singapore calculated the ...................... of generating the electricity to charge the car.
