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 Semi factory is getting a celebration nobody expected
Tesla will inaugurate its Nevada Semi factory September 24, five months after production quietly began ramping.
Tesla says it will officially inaugurate its new Semi factory in Nevada next month. The Tesla Semi account posted the announcement on X, sharing a graphic titled “Semi Rollout” with a date of September 24. No further details were given about the format of the event or who would attend.
While Tesla’s dedicated Semi plant in Sparks, adjacent to Gigafactory Nevada, opened back in April, with the first trucks rolling off the high volume line on April 29, the timing for the factory inauguration comes at a surprise. The ribbon cutting event five months into production is a break from how Tesla has usually handled its other factories, where the first truck or car off the line typically served as the milestone moment.

The 1.7 million square foot factory was built as part of a $3.6 billion expansion Tesla announced in early 2023, and it shares a site with the battery cell lines that feed the Semi’s structural pack, a decision meant to remove the supply bottleneck that delayed the truck for years. The plant is designed for 50,000 trucks a year at full ramp. Semi program director Dan Priestley has said production “is now ramping” rather than claiming it has reached scale.
Nine years passed between the Semi’s 2017 unveiling and this stage of production, with the truck slipping from an original 2019 target through hand built pilot units for PepsiCo and a slow build out of the Nevada plant. An inauguration event now gives Tesla a stage to talk up that ramp and reset expectations for how many trucks it can begin delivering at scale.
The September date also lines up with the Semi’s next milestone. Tesla confirmed the truck is heading to Europe with a full unveiling at the IAA Transportation trade show in Hannover, Germany, running September 15 through 20. Between the Nevada event and the Hannover reveal, Tesla has roughly a week and a half in September to make the case that the Semi is now a truck being built and sold on two continents rather than tested in a handful of fleets.
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Inside Tesla’s secretive $10 Billion “Project Crystal Sun” filing
Tesla filed for a $10.1 billion Fort Bend solar factory, but the site isn’t confirmed.
Tesla has filed paperwork in Texas for a second massive manufacturing project in the same week it locked down its chip fabrication site, this time for a $10.1 billion solar cell plant in Fort Bend County. The filing, submitted July 22 under the state’s Jobs, Energy, Technology and Innovation Act and first surfaced by Sawyer Merritt on X, lists an internal project name of “Project Crystal Sun” and targets a site off FM 762 and FM 1994 near Richmond, about 40 minutes outside Houston.
Tesla is planning to build a $10.1 billion vertically integrated solar cell manufacturing facility in Fort Bend County, Texas, about 40 minutes from Houston, according to a new public application filing.

The application, prepared by Kroll Tax Services on Tesla’s behalf, spans five parcels totaling roughly 3,000 acres within the Lamar Consolidated Independent School District. Tesla wants a 10 year property tax limitation in exchange for the investment, split as $1.5 billion in real property and $8.6 billion in equipment and personal property. The company projects 9,712 permanent jobs once the plant reaches full operation, with 1,147 peak construction jobs during a build window running from this year through 2028 and commercial operations targeted for the first quarter of 2029.
Tesla is not fully committed to Fort Bend County yet. The filing states the company is weighing the site against an unnamed out of state alternative, and frames the tax abatement as what would make Texas competitive against that option. If the district and county decline the incentive, Tesla says it may build elsewhere.
Tesla Megapack Megafactory in Texas advances with major property sale
The plant would handle the full solar cell production chain in one facility, according to the filing, covering wafer and ingot manufacturing, coating, metallization and printing lines, cell testing, automated material handling and cleanroom infrastructure. That scope points to Tesla vertically integrating a part of its supply chain it currently sources largely from overseas partners, mirroring the approach behind its expanding Megapack production in Brookshire, Texas, where Tesla has already built out two buildings for its grid battery business.
The timing lines up closely with Tesla and SpaceX’s other big Texas commitment this month. SpaceX confirmed its Terafab chip factory would land in Grimes County days before this filing surfaced, with construction on that $16.8 billion project starting almost immediately after local officials met with residents. Terafab is meant to produce the AI chips running Tesla’s Optimus robots and Full Self-Driving software, while a solar cell plant would feed a different part of the business, the panels and storage systems Tesla sells to homeowners, businesses and utilities, and increasingly needs to power its own data centers.
Musk has talked about building domestic solar manufacturing capacity before, tying it to the amount of power Tesla’s AI ambitions will require.
