Introduction
The transportation sector is a major contributor to global carbon emissions, with conventional gasoline and diesel vehicles significantly impacting air pollution and climate change. As the world shifts toward a more sustainable future, electric vehicles (EVs) and green transportation solutions are emerging as the key drivers of environmental transformation.
EVs, powered by electricity instead of fossil fuels, offer a cleaner, more efficient alternative to traditional internal combustion engine (ICE) vehicles. Alongside EVs, green transportation solutions—such as public transit electrification, cycling infrastructure, and sustainable fuels—are revolutionizing mobility. These advancements are not only reducing carbon footprints but also promoting energy efficiency and economic growth.
This essay explores the rise of electric vehicles and green transportation, examining their benefits, challenges, and their role in building a cleaner and more sustainable world.
What Are Electric Vehicles (EVs)?
Electric vehicles (EVs) are automobiles that use electric motors and batteries for propulsion instead of conventional gasoline or diesel engines. EVs store electricity in batteries, which power the motor, making them significantly more energy-efficient and environmentally friendly.

How EVs Work
EVs use lithium-ion batteries to store electricity, which is delivered to an electric motor to drive the wheels. When plugged into a charging station, electricity replenishes the battery, allowing continued operation. Regenerative braking, a feature in most EVs, converts braking energy back into stored electricity, improving efficiency.
