1. Electric vehicles now include cars, transit buses, trucks of all sizes, and even big-rig tractor trailers that are at least partially powered by electricity.
Electric vehicles fall into three main categories:
Battery electric vehicles are powered by electricity stored in a battery pack.
Plug-in hybrids combine a gasoline or diesel engine with an electric motor and large rechargeable battery.
Fuel cell vehicles split electrons from hydrogen molecules to produce electricity to run the motor.
It’s more than just passenger cars now — from New York to Mississippi, you may find yourself on a quiet, zipping electric transit bus. The first electric fire truck in the nation will be welcomed by Angelenos in 2021 — and in the coming years,electric sanitation trucks will be quietly gliding through neighborhoods to pick up garbage and recycling, and more electric truck will be delivering packages from warehouses to homes, air pollution-free.
2. Electric vehicles are saving the climate — and our lives. Here’s how.
The largest source of climate pollution in the United States? Transpotation To solve the climate crisis, we need to make the vehicles on our roads as clean as possible. We have only a decade left to change the way we use energy to avoid the worst impacts of climate change.
Emissions from cars and trucks are not only bad for our planet, they’re bad for our health. Air pollutants from gasoline- and diesel-powered vehicles cause asthma, bronchitis, cancer, and premature death.
The long-term health impacts of localized air pollution last a lifetime, with the effects borne out in asthma attacks, lung damage, and heart conditions.
As the COVID-19 pandemic — a respiratory disease — continues to spread, a study by Harvard University found “a striking association between long-term exposure to harmful fine particulate matter and COVID-19 mortality in the United States,”explains Rashmi Joglekar, a staff scientist at Earthjustice’s Toxic Exposure and Health Program. One of the primary causes of fine particulate matter pollution (PM2.5) is combustion from gasoline and diesel car engines.
An earlier study by Duke University underscored the health costs: each gallon of gasoline purchased at the gas station carries with it up to $3.80 in health and environmental costs. The diesel in big rigs and farm equipment is worse, with an additional $4.80 in social costs to our health and climate per gallon.
3. Electric vehicles have a smaller carbon footprint than gasoline-powered cars, no matter where your electricity comes from.
The electricity that charges and fuels battery electric and plug-in hybrid vehicles comes from power grids, which rely on a range of sources — from fossil fuels to clean renewable energy.
Energy grids can vary from one state to another, which means that the carbon footprint of driving an electric vehicle ranges depending on the source of its electricity.
Earthjustice attorneys are working across the country to bring 100% clean energy, but on our way there (consumption of renewable energy recently surpassed coal), a portion of the electricity in this country will continue to be generated by the burning of fossil fuels.
The very good news? Because electric vehicles are more efficient in converting energy to power cars and trucks, electricity across the board is cleaner and cheaper as a fuel for vehicles, even when that electricity comes from the dirtiest grid.
Running electric or hybrid cars on the grid in any state has lower greenhouse gas emissions than gasoline-powered cars, as revealed in a study by experts at the Union of Concerned Scientists. And as states clean up their energy grids, the benefits of electric vehicles become stronger.

4. Through their entire lifetime, electric cars are better for the climate.
In the manufacturing process, electric vehicles will produce more global warming emissions than the average gasoline vehicle, because electric cars’ large lithium-ion batteries require a lot of materials and energy to build. (For example, manufacturing a mid-sized electric car with an 84-mile range, results in 15% more emissions.)
However, once the vehicles get on the road, it’s a whole different energy story.
Electric vehicles make up for their higher manufacturing emissions within, at most, eighteen months of driving — and continue to outperform gasoline cars until the end of their lives
The average electric car on the road today has the same greenhouse-gas emissions as a car getting 88 miles per gallon — which is far greater than the average new gasoline-powered car (31 mpg) or truck (21 mpg), according to analysis by the Union of Concerned Scientists.
5. Electric vehicles can charge up at home, at work, while you’re at the store.
One advantage of electric vehicles is that many can be recharged wherever they make their home, whether that’s your home or a bus terminal. This makes electric vehicles a good solution for truck and bus fleets that return regularly to a central depot or yard.
As more electric vehicles hit the market and are used more broadly, new recharging solutions — including adding more public charging locations in shopping centers, parking garages, and workplaces — will be required for people and businesses without the same access at home.
“Having dependable charging at work let me buy a plug-in hybrid car without hesitating,” Ari Weinstein, a research scientist, Shared withSara Gersen an Earthjustice attorney and clean energy expert. Weinstein is a renter who has limited options to be able to charge at home.
“The opportunity to drive an electric car shouldn’t be limited to people who own a home with a garage,” explains Gersen.
“Workplace charging is one key element of democratizing access to electric cars, and we need to move aggressively if we are going to meet this challenge. Electric utilities have abig role to play”
6. Planning now by states and utilities to build infrastructure for charging electric vehicles will go a long way.
7. Transit buses, that reliable fixture rumbling through our towns and cities, may just be the key to the electric vehicle revolution.
8. Electric trucks — delivering goods from warehouses to homes — can make a big, clean difference. We need more of them.
