The Impact of Electric Vehicles on the Automotive Industry

Looking at the environmental, economical, and political impact of electric vehicles.

By Patrick Peterson of GoodCar

Electric vehicles (EVs) have had a remarkable glow-up in a relatively short period. It wasn’t so long ago that public opinion labeled them as overpriced, inefficient options with poor mileage to boot. However, rising climate concerns and the volatility of gas prices have pushed more people to refresh their understanding of the technology. While misinformation is rampant, people’s faith in EVs has risen enough that over 40 percent of Americans would seriously consider making the switch. Growing interest pressures manufacturers to reorganize their supply chains with a stronger emphasis on EVs. This sounds simple, but there are significant differences in EV development compared to gas-powered cars. The longstanding dominance of gas-powered vehicles makes most people believe it was the only option up until now. But that’s wrong. The idea of electric vehicles has been experimented with since the early 1800s. Robert Anderson is credited for inventing the first electric vehicle. The Scottish inventor used primary cells (single-use batteries) to power a motor he fixed to a carriage. This idea for a “horseless carriage” was a pivotal moment in history that gave future inventors a foundation to work on. Jump to today, and EVs have skyrocketed in popularity. They’ve proven to be a more sustainable option and have a lower overall cost than gas-powered cars. Opponents of adopting EVs argue that battery-powered vehicles aren’t entirely emission-free. And they’re right. Carbon emissions are created during the manufacturing process and when charging the battery. This is because fossil fuels are required to mine the minerals used in batteries and to generate the power used to recharge them. However, these emissions are substantially lower than those released by cars using an internal combustion engine. A study performed by MIT found that electric-powered cars created about 25 percent fewer carbon emissions per mile than a gasoline alternative. This study even assumed the cars were in less eco-friendly states. When Washington was used as the backdrop, the study reported that an EV would create 61 percent fewer emissions. This is due to Washington drawing a lot of its energy from hydropower. Norway, Europe’s biggest EV market, takes a similar approach. Over half of Americans are willing to pay more for sustainably responsible products. A comparable number of citizens say the same thing about gasoline. This support for greener brands shows the automotive industry how the future will look. Manufacturers’ supply and production procedures must start adapting now to prepare for the future. There are even various government incentives to make the process easier.

Resolução comentada

"Volatility" é o substantivo de "volatile". Aplicado a preços ou mercados, significa que os valores mudam muito e de forma rápida, sem que se consiga prever para onde vão: são instáveis e imprevisíveis.

O contexto confirma isso. A frase diz que "rising climate concerns and the volatility of gas prices have pushed more people to refresh their understanding of the technology" (a preocupação com o clima e a volatilidade dos preços da gasolina levaram mais gente a rever o que pensa sobre os carros elétricos). Para que a oscilação dos preços empurre as pessoas a buscar alternativas, ela precisa ser um problema, ou seja, uma instabilidade que gera insegurança. Preços previsíveis ou estáveis não teriam esse efeito.

Assim, o sentido mais próximo de "volatility" é "unstable and unpredictable", que corresponde à alternativa E.

Alternativa E.

Por que as outras alternativas estão erradas

  • A"Predictable and routine" é o oposto de volátil; preços voláteis não são previsíveis.
  • B"Steady and consistent" também é o contrário de volatilidade e não justificaria a mudança de opinião sobre os EVs.
  • C"Environmentally friendly" não tem relação com o sentido de "volatile"; só liga o termo ao tema ambiental do texto.
  • D"Decreasing gradually" indica queda lenta e contínua, e volatilidade é oscilação brusca em ambos os sentidos.
