Electric vehicles (EVs) are powered by electricity instead of gasoline, making them a much cleaner alternative to traditional cars. They are an essential part of the plan to cut the nation's oil use in half in 20 years. However, the question of whether everyone should drive an EV is complex. While they are a great way to reduce emissions and improve air quality, there are other factors to consider, such as the higher upfront cost of EVs, “range anxiety”, and the fact that current government subsidies tend to benefit wealthier households that use EVs as a secondary vehicle.

What You'll Learn
Electric vehicles are cheaper to fuel than traditional cars
Electric vehicles (EVs) are generally cheaper to fuel than traditional cars. A 2018 study by the University of Michigan's Transportation Research Institute found that the average cost to fuel an electric car was $485 a year, compared to $1,117 for a gas-powered vehicle. Similarly, a 2020 Consumer Reports study found that EV drivers spend about 60% less on fuel costs annually compared to drivers of gas-powered cars.
The cost-effectiveness of EVs is further demonstrated by their higher efficiency in travelling a mile compared to gasoline internal combustion engines. This efficiency is measured by kilowatt-hours (kWh) of electricity consumed per 100 miles. Additionally, public charging stations tend to be more expensive than charging at home. Charging an EV at home overnight can result in significant savings, as electricity demand and prices are typically lower during this period.
However, it is important to note that the upfront cost of purchasing an EV can be higher than that of a traditional car. The higher purchase price may be a challenge for low-income households. Nonetheless, with automakers reducing EV prices and federal incentives for eligible buyers, the price gap is expected to narrow in the coming years.
While the cost savings of EVs are not universal and can vary based on location and specific models, they generally offer a more affordable fuelling option than traditional cars. This is especially true when considering the potential for state and local incentives, as well as the reduced maintenance costs associated with EVs due to their simpler mechanical design.
In summary, electric vehicles are generally cheaper to fuel than traditional cars, and with advancements in technology and increasing adoption, we can expect to see further improvements in the affordability and accessibility of EVs.

They are also cheaper to maintain
Electric vehicles (EVs) are generally cheaper to maintain than traditional cars. This is because they have a simpler design with fewer moving parts, which means there are fewer components that may wear out and need replacing. For example, EVs do not have spark plugs, transmissions, radiators, or oil that needs changing. This lack of routine maintenance requirements means that EVs are cheaper to maintain over the lifetime of the vehicle.
In addition, EVs have regenerative braking, which uses the electric motor to decelerate the vehicle, extending the lifespan of brake pads and rotors. This feature further reduces maintenance costs. EVs also have fewer parts that need to be tuned up, such as spark plugs, timing belts, and other engine components. As a result, EV owners can expect to save over $1,500 in maintenance costs compared to a gasoline-powered vehicle.
The reduced maintenance costs of EVs are a significant advantage for drivers, as they provide cost savings and convenience. In a 2022 Consumer Reports survey, 33% of respondents cited reduced charging costs as the main reason for choosing an EV, and 28% selected lower maintenance costs. In addition, EVs are often eligible for tax credits and rebates, which can help offset the higher upfront cost of purchasing an EV.
However, it is important to note that the benefits of EVs in terms of cost savings and environmental impact are most significant for frequent drivers or those who plan to keep their car for many years. This is because the upfront cost of EVs is typically higher, and it takes time to recoup these costs through reduced maintenance and fuel costs. For example, a household that drives an EV as their primary car will take about 2.73 years to gain a "green lead" over a gas-powered car. In contrast, those who use an EV as a secondary vehicle may need to keep it for about a decade to see any emissions benefit.
Overall, while EVs have cheaper maintenance costs than traditional cars, it is important for prospective buyers to consider their driving habits and the total cost of ownership when deciding whether to switch to an EV.

Electric vehicles are better for the environment
Electric vehicles (EVs) are widely considered to be better for the environment than traditional cars. They are marketed as having "zero emissions", but this is not entirely accurate. While it is true that EVs do not emit greenhouse gases from their tailpipes, emissions are created during the manufacturing process and when charging the vehicles.
However, EVs are still a lower-emissions option than cars with internal combustion engines. Over their driving lifetimes, they will create fewer carbon emissions than gasoline-burning cars under nearly all conditions. This is especially true in countries like Norway, which draws most of its energy from hydropower, giving EVs charged in the country a minuscule carbon footprint. Even in countries that rely on burning coal for energy, EVs are still on par with or better than burning gasoline in terms of emissions.
EVs also have other environmental benefits. They are mechanically much simpler than conventional cars, so maintenance requirements are often simpler and cheaper. They do not require oil changes, spark plug changes, or timing belt replacements, for example. This can save an EV owner over $1,500 over the life of the vehicle compared to a gasoline-powered car.
However, some critics argue that the environmental benefits of EVs are overstated. For example, lithium is required to build EV batteries, and the process of extracting it is chemical- and water-intensive. In addition, some people who purchase EVs as a secondary vehicle may not drive them enough to gain any emissions benefit over a traditional car.
Overall, while EVs may not be a perfect solution, they still offer a cleaner and better way to fuel transportation for many people.

They improve our air quality
Electric vehicles (EVs) improve air quality by reducing harmful ground-level ozone, the principal component of smog. They do this by lowering net emissions of nitrogen oxides (NOx) and volatile organic compounds (VOC). A study by the Union of Concerned Scientists found that electric vehicles can cut US oil use by 1.5 million barrels a day by 2035.
EVs also improve air quality by reducing carbon pollution from transportation. A study by the Electric Power Research Institute (EPRI) and the NRDC found that transitioning from a near sole dependence on oil to electricity can lead to significant reductions in carbon pollution and improvements in air quality. The study also found that the electricity used to power EVs can generate emissions, but these emissions levels are far lower than those of conventional vehicles and are expected to decrease over the next few decades as the electric power sector becomes cleaner.
In California, a study found that every 20 zero-emissions vehicles per 1,000 people in a given zip code led to a 3.2% drop in the rate of emergency room visits due to asthma. The researchers tracked electric vehicle registrations and local measurements of nitrogen dioxide, a pollutant produced by conventional engines that can cause breathing problems and trigger the formation of other pollutants. As the number of zero-emissions vehicles increased, ER visits decreased.
However, it's important to note that the benefits of improved air quality from EVs are currently skewed towards wealthier communities as they are the ones who can more easily afford them. Additionally, some argue that infrequent drivers or those who plan to own an EV for a short period may be better off driving a gasoline-powered car as the high emissions buy-in of an EV can take years to offset.

Electric vehicles are faster and more powerful
Electric vehicles (EVs) are faster and more powerful than traditional gas-powered cars. They have greater horsepower, with a standard electric car offering about 120hp and models like Tesla's Model S providing between 360–470hp. This extra power means that EVs can accelerate faster and achieve impressive zero to 60 times of just two to three seconds. For example, the 2017 Tesla Model S P100D achieved a time of 2.275 seconds, making it the quickest stock production vehicle ever at the time.
The instant torque and simplified powertrain of EVs enable them to take off from a stop much faster than gas vehicles with similar power specs. This efficiency is due to EVs having fewer moving parts, allowing them to run more efficiently and reducing maintenance costs. EVs also have more advanced traction control systems, calculating the torque each wheel receives to prevent spin-outs. Additionally, their wider tyres and low centre of gravity further enhance handling and grip.
While EVs may have a slower top speed due to the lack of a traditional transmission, engineers are working on new transmission designs to address this issue. A well-designed transmission for an EV would help manage power delivery and battery range, enabling faster speeds for more extended periods while wasting less energy. This technology could also extend the range of electric cars, which is currently limited to about 250–310 miles.
Overall, the performance of EVs has been recognised in race series like Formula E, and they offer higher performance and acceleration than traditional gas-powered cars while also reducing air pollution.
