Determinants of electric vehicle emissions savings and costs across locations and individuals Marco Miotti and Jessika E Trancik*

Following is in video description by @MoneyShift

The most common argument against electric cars is that once you factor in battery manufacturing and lithium mining, they aren't actually cleaner. MIT tested that directly, and the answer is no longer ambiguous.

Researchers Marco Miotti and Jessika Trancik built a lifecycle model covering thousands of US zip codes, drilling down to individual driver behavior rather than comparing broad regions. They accounted for battery and vehicle manufacturing, fuel extraction and refining, regional electricity mix, local meteorological data, traffic density, trip length and duration, acceleration patterns, gas and electricity prices, and state fees. The study appears in Environmental Research Letters.

The concession first: building a battery is dirtier than building a comparable gas car, and an EV starts life with a larger manufacturing footprint. MIT states that plainly rather than working around it.

The findings: in most US locations, a battery electric vehicle reduces lifetime greenhouse gas emissions by 40 to 60 percent compared to a similar gas vehicle, with larger reductions in urban areas. On cold weather, MIT found that in a climate like North Dakota, efficiency can drop as much as 50 percent on a particularly frigid night, but the effect on annual emissions benefits is minimal. Miotti's own conclusion was that even in the most unfavorable conditions, EVs still reduce emissions substantially.

On cost, EVs are competitive with comparable combustion vehicles in lifetime ownership cost across most of the country, even without clean vehicle tax credits. Where electricity is relatively affordable, battery electrics tend to cost less outright. The study also found that individual driving behavior matters roughly as much as regional electricity mix, with the biggest reductions going to people who drive more, drive larger vehicles, and spend more time in traffic.

MIT also updated their public tool at carboncounter.com, where you can compare lifecycle emissions and ownership costs for nearly any car on the market.

None of this means you have to like electric cars. Dislike the steering feel. Dislike the brake feel. Want a manual. Those are real objections. The emissions one is finished.

The US Postal Service effort to develop a sweeping new system for verifying mail ballots has invited a host of IT concerns among agency officials, with some describing the process internally as a “sh*t show,” according to a new whistleblower report released Tuesday by a Democratic senator.

The unnamed whistleblower is alleging that some of the procedures USPS is planning – under mandates put forward by President Donald Trump – have been hidden from the public. Those procedures will make an already complicated and risky plan even more vulnerable to potential mass disenfranchisement, the whistleblower says.

The new report – which was assembled by the whistleblowers’ lawyers and released by Connecticut Sen. Richard Blumenthal – comes as multiple courts are considering the legality of the proposal, which would require that states submit to USPS lists of their mail-in voters. The agency will not deliver ballots for states if there are any discrepancies between the voter information in the USPS system and what’s picked up by agency scanners on the envelopes of the ballots.
