Below are two groups of people talking about electric cars.
Pros (Agree)
Peter: Not like a petrol car, an electric car doesn’t need gas and doesn’t make loud noise. In Norway, an electric car gets almostall its power from wind-powered plants. And some car sellers are working on the so-called “second-life” batteries.
Max: From studies in the US, electric cars are greener than other cars when it comes to the life of a car. An electric car uses onlytwo-thirds of the power of a petrol car.
Sophia: An electric car uses 38 megajoules to move around. However, a petrol car needs 142 megajoules.
Cons (Not Agree)
Elle: In most countries, to give power to electric cars, the car company builds power stations to make batteries. While buildingthem, they make more greenhouse gas.
Carles: The power for the electric cars mostly comes from the oil-fired power plant. And the oil comes from the gas. And forevery 100km, it takes 74 megajoules to get gas out of the ground and send it to an electric car, but it only takes 26 megajoules fora petrol car.
Claire: Making a petrol car will take 5.6 tonnes of CO2, while for an electric car, it is 8.8 tonnes. Half of the CO2 happens inmaking the battery. An electric car also gives off 80% of the greenhouse gas of a petrol car.
