A report released by the University of Michigan’s Transportation Research Institute is showing the cost savings to the average vehicle owner versus those same owners driving electric. The report compares gasoline fuel costs state-by-state to the cost of electricity for equivalent miles driven. The differences are shown in both ratios and dollar figures, with owners in some specific states seeing much higher savings when driving electric versus those from other states.
The report is unique in that it ignores the often-politicized arguments for data of this nature; such as the “source-to-use” data often manipulated or argued. Instead, it looks purely from a consumer perspective, showing what kinds of cost savings could be had for the average vehicle owner in any given state.
By comparing the average fuel economy of cars sold with the average expected range of a battery-electric vehicle sold on the market, the report found that drivers in Washington State, Oregon, Idaho, Louisiana, and Utah would save the most by switching to an electric vehicle. Drivers in Hawaii, New Hampshire, Connecticut, Rhode Island, and Massachusetts would save the least. Most of these differences are due to a lower disparity between gasoline costs and residential electricity costs in the latter list of states and a higher disparity between those in the former list.
The report’s data considered the average driving distance and amount per state (NHTSA data), the average fuel economy of vehicles sold in that state (per another UofM study), the average cost per gallon for gasoline state-by-state (according to AAA), and the average cost of electricity in each state (per EIA). The report then compared these to one another.
The average cost of gasoline in the United States, as of December 23, 2017, was $2.441 per gallon. The highest price was in Hawaii at $3.297 per gallon and the lowest was in Alabama at $2.169. High fuel costs, however, did not always translate directly into more savings with a battery electric vehicle. Similarly, lower fuel costs were not necessarily a guarantee that the payoff for going electric would be minimal. Electricity costs could change that.
And they did. The average price of residential electricity in the United States, as of October 2017, was $0.1284 per kilowatt hour. Hawaii had the highest price at $0.2929 per kWh and Louisiana had the lowest at $0.0972/kWh. The higher cost of electricity was more of an indicator of lower gains by going to an electric vehicle than were gasoline prices. Most of the states in the top five for benefiting the least by going electric were also within the top ten for the highest-priced electricity. Yet the states with the lowest-priced electricity were not likely to show up on the top five list for the best gains by getting an EV.
For overall averages nationwide, the cost of driving a gasoline vehicle was $1,117 per year while the average cost of driving a battery electric vehicle was $485. On the whole, most Americans can expect to save at least something if they go to an electric vehicle for most of their driving.
Also interesting was the average fuel economy required in order to meet or better the electric vehicle’s cost savings to the owner. Even in the worst states, where ratios were lowest, the average fuel economy was relatively high. In Hawaii, where a gasoline car owner can only expect to save about $400 per year for getting an EV, the required fuel economy to average that cost ratio out to $0 is 34.1 mpg. In the average state, the fuel economy required is around 57.6 mpg. In the state of Washington, a full 90 mpg is required to break even with an electric car.
These numbers are interesting and should speak directly to consumers at a bare-bones pocketbook level. Buying an EV can mean significant annual savings. The report, Relative Costs of Driving Electric and Gasoline Vehicles in the Individual U.S. States, can be found at this link.
Tesla has chosen the location of its latest manufacturing project, a facility that will churn out the Megapack, a large-scale energy storage system for solar energy projects. It has chosen Waller County, Texas, as the location of the new plant, according to a Commissioners Court meeting that occurred on Wednesday, March 5.
Around midday, members of the Waller County Commissioners Court approved a tax abatement agreement that will bring Tesla to its area, along with an estimated 1,500 jobs. The plant will be located at the Empire West Industrial Park in the Brookshire part of town.
Brookshire also plans to consider a tax abatement for Tesla at its meeting next Thursday.
The project will see a one million square-foot building make way for Tesla to build Megapack battery storage units, according to Covering Katy News, which first reported on the company’s intention to build a plant for its energy product.
CEO Elon Musk confirmed on the company’s Q4 2024 Earnings Call in late January that it had officially started building its third Megapack plant, but did not disclose any location:
“So, we have our second factory, which is in Shanghai, that’s starting operation, and we’re building a third factory. So, we’re trying to ramp output of the stationary battery storage as quickly as possible.”
Tesla plans third Megafactory after breaking energy records in 2024
The Megapack has been a high-demand item as more energy storage projects have started developing. Across the globe, regions are looking for ways to avert the loss of power in the event of a natural disaster or simple power outage.
This is where Megapack comes in, as it stores energy and keeps the lights on when the main grid is unable to provide electricity.
Vince Yokom of the Waller County Economic Development Partnership, commented on Tesla’s planned Megapack facility:
“I want to thank Tesla for investing in Waller County and Brookshire. This will be a state-of-the-art manufacturing facility for their Megapack product. It is a powerful battery unit that provides energy storage and support to help stabilize the grid and prevent outages.”
Tesla has had a lease on the building where it will manufacture the Megapacks since October 2021. However, it was occupied by a third-party logistics company that handled the company’s car parts.
Tesla Energy has become the undisputed dark horse of the electric vehicle maker. This was highlighted by Tesla Energy’s growing role in the company’s overall operations in the past quarters.
And as per Tesla’s year-end milestone posts on X, Tesla Energy had a blockbuster 2024.
Tesla Energy’s 2024 milestones:
- As per Tesla on its official social media account on X, the company has hit over 800,000 Powerwalls installed worldwide.
- From this number, over 100,000 Powerwall batteries have been enrolled in virtual power plant (VPP) programs.
- The Powerwall 3 has officially been launched in the United States, Canada, Puerto Rico, the U.K., Germany, Italy, Australia, and New Zealand.
- The Tesla Megapack hit over 22 GWh in operation across more than 60 countries across the globe.
- The Lathrop Megafactory, which produces the Megapack, has been ramped to 40 GWh per year.
- The Lathrop Megafactory has also produced its 10,000th Megapack battery.
- The Shanghai Megafactory was completed in just seven months, and it is ready to start Megapack production in Q1 2025.

Powerwall owners’ 2024 impact:
- As per Tesla Energy, Powerwall owners generated a total of 4.5 TWh of solar energy globally in 2024. This was equivalent to powering a Model 3 for more than 17 billion miles.
- A total of 1.1 TWh of energy was stored in Powerwalls in 2024. This protected homes from over 5.8 million outages during the year.
- Tesla’s Storm Watch feature for Powerwall batteries covered 2.8 million severe weather events over the year.
- Powerwall owners saw collective savings of over $800 million on utility bills.
- Virtual Power Plants contributed over 2.2 GWh of power to the grid. This reduced the need for 2,200 metric tons of fossil fuel peaker plant emissions.

“This project is being built in rural Utah, by rural Utahns, and for all of Utah. When rural Utah thrives, the entire state prospers. Today, we’re not just breaking ground—we’re building a future of affordable, abundant energy in Utah,” the official noted.
The Green River Energy Center secured over $1 billion in construction debt financing earlier this year. The facility is also expected to create about 500 jobs, many of which will be filled by local workers. With this in mind, the solar and battery farm would likely prove to be a boost to Emery County’s economy, enhancing tax revenue, strengthening public services, and offering long-term employment opportunities for the area’s residents.
Sundt Construction will serve as the project’s contractor, EliTe Solar will supply the solar modules, and Tesla will provide the battery storage system for the project. Luigi Resta, President and CEO of rPlus Energies, noted that the Green River Energy Center is special because of the entities that have worked together to make the facility a reality.
“It’s the partners that make this project special, that have made this monumental project possible. From our equipment providers to the onsite talent, and the support of the local and regional community, we owe this project’s success to each of you,” he stated.
