How Gas and Electric Cars Impact the Environment
This paper examines the environmental effects of both gas-powered and electric vehicles in the United States. Drawing on data from the EPA and other sources, it discusses how transportation accounts for 29% of U.S. greenhouse gas emissions, the infrastructure and noise pollution caused by car dependency, and the environmental costs of automotive manufacturing. The paper then evaluates electric vehicles as an alternative, weighing their production costs — including battery manufacturing and lithium sourcing — against their long-term benefits such as reduced emissions during use, lower noise pollution, and improving infrastructure. The paper concludes that while electric vehicles are not a perfect solution, they represent a meaningful step toward reducing the transportation sector's environmental footprint.

What makes this paper effective
- Uses specific, cited statistics (e.g., 29% of U.S. greenhouse gas emissions from transportation, 150 kg of CO2 per kWh of battery capacity) to ground its claims in credible data.
- Presents a balanced comparison by acknowledging environmental costs on both sides — gas vehicles and electric vehicles — rather than advocating uncritically for one option.
- Moves logically from the problem (gas cars and emissions) through manufacturing costs to a nuanced evaluation of the proposed solution (EVs), maintaining a clear argumentative thread.
Key academic technique demonstrated
This paper demonstrates effective use of counter-argument and concession. When introducing electric vehicles as an alternative, the author immediately acknowledges their environmental drawbacks (battery production costs, lithium sourcing) before presenting their advantages. This technique strengthens the paper's credibility by showing awareness of complexity rather than oversimplifying the issue.
Structure breakdown
The paper is organized into two main conceptual halves: the environmental impact of gas-powered vehicles (emissions, infrastructure, manufacturing) and the environmental profile of electric vehicles (production costs, operational benefits, remaining limitations). Each half builds on the previous, culminating in a measured conclusion that neither dismisses EVs nor treats them as a complete solution. The structure suits a short comparative essay well.
Introduction: Transportation and Climate Change
According to the Environmental Protection Agency (EPA), gas-powered cars are one of the most significant sources of emissions contributing to global warming in the United States. Transportation-related emissions are responsible for 29% of greenhouse gas emissions in the U.S. alone, making transportation the largest contributing sector to climate change ("Carbon Pollution from Transportation"). Despite the development of electric vehicles, hybrid cars, and more fuel-efficient vehicles, the transportation sector's contribution to global warming increased more than any other sector from 1990 to 2019 ("Carbon Pollution from Transportation").
Infrastructure and Driver Behavior
Car use can also have significant impacts on the general infrastructure of the nation, requiring the construction of major highways that result in noise pollution and the disruption of natural habitats. The need for adequate parking and driving areas can reduce walkable spaces and places for people to enjoy the environment, further compounding noise pollution. Many driving habits contribute to emissions as well, thanks to long commutes and time pressures that lead to rapid acceleration or extended idling in traffic ("Reducing Air Pollution From Cars").
The Environmental Cost of Vehicle Manufacturing
Manufacturing vehicles is not without significant environmental costs. Currently, the most significant source of automotive production worldwide is China, followed by the United States and Japan (Gorton). Although the automotive sector declined somewhat worldwide during the pandemic, concerns about the environmental damage caused by production, vehicle use, and a lack of viable public transportation options — particularly in the United States — keep the sector's impact a continued subject of debate. Many citizens are entirely dependent on cars for commuting to work and completing everyday errands.
