Gasoline vs. Electric Cars

Gasoline vs. electric cars is a subject of debate for many modern vehicle producers, consumers, and users. Automobile technology dates back to the 1800s and likely earlier. Although early inventors experimented with electric motors, gasoline-powered engines became the industry standard for several generations. Only in the late twentieth century did environmental concerns draw many scientists and reformers to revisit electric-powered vehicle designs. In the twenty-first century, consumers may choose between traditional gasoline-powered vehicles and electricity-powered vehicles (including all-electric or hybrid-electric). Although visually quite similar, these vehicles differ greatly in their performance, financial requirements, and effects on nature.

Background

For most of their history and the period in which they rose to international prominence, automobiles have primarily been gasoline-powered machines. Some people believe that the push for electric vehicles in the twenty-first century is a purely modern trend. However, the earliest automobiles, dating back to the 1800s and likely earlier, used a variety of means of propulsion, including electricity, gasoline, and even steam power. By the late 1800s, several early experimental automobiles used electricity stored in large portable batteries. These vehicles were important milestones in the evolution of modern automobiles. However, they also tended to be slow, and their batteries required lengthy recharge periods, rendering them frequently immobile.

Inventors quickly dismissed electrical vehicles when gasoline engines came to the forefront. Some of the first gasoline engines appeared in Europe in the 1860s and 1870s. Automobile designers found these engines—while still weak and temperamental by modern standards—more useful than their electric counterparts. Gasoline engines could produce equal or greater energy and be recharged simply by adding more liquid fuel to their storage tanks, a process that took seconds instead of hours.

Despite decades of experimentation and invention, automobiles were still far from a marketable commodity. Several new innovations in the late 1800s changed that. Many historians credit German engineer Karl Benz as being the first person to create a modern automobile using a set method of production. His work in 1885 and 1886 showed that efficient vehicles could be created quickly and inexpensively enough to become accessible to regular citizens.

In 1896, American inventor and entrepreneur Henry Ford entered the automobile industry, which he would quickly reshape and begin to dominate. His vehicle designs brought further improvements to the work of prior inventors. Just as importantly, he expanded greatly upon the work of Benz in creating the assembly line system. With this system, enormous mechanized factories, staffed by workers trained in a limited number of skills, could produce unprecedented quantities of vehicles at lower-than-ever prices.

By the 1920s, automobiles had progressed from eccentric and inefficient novelties to a mainstay of many larger cities. In the coming years, increased production efficiency and reduced cost would make automobiles available to large percentages of the global population. At the close of the twentieth century, automobiles including cars, trucks, and motorcycles numbered in the hundreds of millions and were everyday sights in almost all corners of the world. Many people consider automobiles a necessary staple of modern life.

Of all the innovations in the long development of automobiles, the use of alternative energy sources almost completely disappeared for several generations. Automobiles and gasoline-powered engines became practically synonymous, and drivers consumed billions of gallons of gasoline and other petroleum-based products for their vehicular needs. The ease-of-use, efficiency, and relative abundance of these products made many owners and manufacturers never pause to question them. By the later twentieth century, however, perceptions began to change.

The vast amount of gasoline used in the automobile industry had a negative impact on the environment. Scientists publicized the dangers of using massive amounts of fossil fuels, including oil-based products like gasoline. These energy sources create harmful by-products that contribute to environmental woes including smog, acid rain, and climate change. In addition, fossil fuels are nonrenewable, meaning that their availability on Earth is finite. Supplies of oil and gasoline may be interrupted, leading to supply limits, price fluctuations, and even international turmoil. Moreover, these materials will someday run out and cannot be replaced.

With concerns about fossil fuels rising, scientists and reformers critically re-evaluated the automobile designs that had dominated the market for so many decades. By the beginning of the twenty-first century, a call had begun to shift the world’s energy dependence toward cleaner and more renewable fuels. Renewable fuels are those that are practically infinite in quantity; they also tend to cause less degradation to the environment. As people returned to ancient power sources such as solar, wind, and water power, so too did scientists revisit the forms of electrical power that had propelled some of history’s first automobiles.

Overview

The consumers of modern automobiles have more choices than ever in terms of styles and models available, as well as types of propulsion systems. Whereas most of the world’s vehicles are propelled by gasoline engines, electricity-powered engines are growing in popularity. Even within this category, consumers have several choices.

The most basic and purest form of electric vehicle is known as all-electric. This type of automobile has an exclusively electric motor powered by a rechargeable battery containing stored electricity. When the battery runs low, the vehicle’s performance becomes limited. Users must recharge the battery, usually by plugging it into an external, stationary power source. Many owners recharge at home, but a growing number of public charging stations have become available internationally.

The second main category of electric vehicles is not wholly electric. Instead, it relies on a combination of electric and gasoline technologies. This type of vehicle is known as a hybrid electric, or simply “hybrid.” Hybrids have two power plants: a traditional internal-combustion engine powered by gasoline, as well as an electric motor powered by a battery. Hybrid types vary depending on which power plant is the primary source of propulsion. Some primarily use the electric motor, while reserving the gasoline engine as a backup. Others use the opposite configuration. In many hybrids, the gasoline engine serves as a generator to charge the battery of the electric motor.

Many consumers prefer hybrid cars because they offer greater range than all-electric cars. Most American all-electric vehicles have a range of approximately 300 miles before they require recharging. Hybrids, however, may leverage the benefits of both engines to drive farther and more reliably. Users are less likely to find themselves with no power, or having to pause trips for hours to recharge batteries. However, gasoline engines still remain the leader in distance, with many drivers able to travel several hundred miles on a tank of gasoline and then refill it in just minutes at many convenient refueling stations.

Proponents of electric vehicles, all-electric and hybrid alike, are often attracted to the relative environmental friendliness of these automobiles. All-electric vehicles use no fossil fuels and produce little if any harmful emissions. Hybrids do use some fossil fuels and produce some tailpipe emissions, but these levels are much lower than in all-gasoline vehicles. Electric engines are also comparatively silent compared to their gasoline-powered counterparts.

A benefit unique to electric vehicles is that some use a system called regenerative braking that captures energy from the brakes and converts it into additional charge for the battery. Another system, auto start-stop technology, allows the engine to shut down during pauses, such as red lights, and restart automatically when the driver accelerates. Particularly in stop-and-go traffic, this technology, which was also increasingly available in gasoline-powered cars to help reduce fuel consumption, added to a car’s mileage, efficiency, and environmental friendliness.

Price differences are a major factor in many purchasing decisions. Traditional gasoline-engine technology has existed for many generations and been honed to a high level of efficiency and relative affordability. Consumers have greater options in makes and styles for lower prices. Meanwhile, electric vehicles, such as the Tesla manufactured by Tesla Inc., are comparatively newer and produced in smaller quantities, contributing to reduced options and higher-than-average purchase prices. However, prices of electric vehicles had decreased significantly by the early 2020s. In 2023, for example, the average price of a new electric vehicle was $14,000 less than the previous year. Moreover, tax incentives helped to mitigate costs further for purchasers of electric vehicles. The federal EV tax credit gave buyers $7,500 for new electric vehicles and $4,000 for used ones in 2023.

Although gasoline-powered vehicles are generally less expensive to purchase, electric vehicles usually hold the advantage in other financial respects. The cost to operate electric vehicles per mile is generally significantly lower than the cost of operating gasoline-powered vehicles. Recharging a battery may cost only a fraction of the price of a tank of gasoline. The cost of maintenance, meanwhile, differs between vehicle types. Gasoline-powered vehicles are more familiar to mechanics, and replacement parts are more readily available. However, electric engines have fewer moving parts than gasoline engines, meaning they may be less likely to malfunction and easier to service if they do. Furthermore, electric vehicles do not require much of the routine maintenance, such as oil changes, that are needed for gasoline-powered vehicles.

Despite the many differences between gasoline and electric-powered vehicles, these forms of automobiles are also alike in various ways. They both serve the purpose of carrying people and cargo. They may both be rendered in different styles, such as sedans, coups, pickup trucks, sport-utility vehicles, and motorcycles. From the outside, gasoline and electric-powered vehicles may appear quite similar, with the only major difference being the lack of a tailpipe in all-electric models. Ultimately, the choice to use gasoline or electric vehicles is up to the consumer and his or her individual expectations and requirements.
