Hello, we like Analytics.

Background

We are engineers from across the country with a passion for data science and analytics.

Have you ever wondered how much CO2 you actually make by driving? It is surprisingly difficult to figure out what is coming out of your tailpipe. What about cars without tailpipes? Electric Vehicles (EVs) don't emit anything directly, however, the electricty has to come from somewhere, and many forms of power generation do emit CO2. This tool was created to help you understand what emissions your car is creating, including EVs, based on their effeciency and power source.

We collect data from the Energy Information Agency (EIA) and represent the electricity generation and associated emissions in your state. This is the primary source of emissions for EVs

We also leverage a large database of vehicle information from fueleconomy.gov for specific vehicle information.

• To learn more, view our process.

This lifetime emissions and liquid fuel or electricity cost visual allows you to see the pros and cons of EV vs. Hybrid vs. Gas vehicles in terms of operating expenses and environmental impact for your state of choice. The cars shown are the same year and car type as the vehicle you selected in the Vehicle: 1 dropdown. A clustering algorithm groups similar car models based on emissions and cost metrics. Your Vehicle 1 selection is shown as the large, bolded circle in the plot.

Experiment with different states and car models to minimize your operating costs and emissions!

This analysis makes the following assumptions about the lifetime of the vehicle

• 8 years of use
• 150,000 miles

Emissions in your state

EV emissions are highly dependant on which power sources are used to generate electricity. To estimate EV emissions in your state, try the following tool!

You will be able to see where power comes from in your state. Some sources, such as coal and petroleum create high levels of CO2 emissions, while others such as wind and solar create none. Because of the mix of fuels in each state, an EV will "create" more or less emissions based on the state it is charged in!

Of course, the emissions created by driving is very dependant on the car you're driving. The tool below allows you to select some cars. Based on their fuel economoy (or electrical effeciency for an EV), we can estimate how much CO2 a car makes every mile.
