How Elizabeth lands in front of the camera, rather than under a fume hood, receives frank, satisfying treatment in this briskly paced, often funny, occasionally troubling, brew of a book. The earnest speaker of this truth is 30-something scientist Elizabeth Zott, the protagonist of Bonnie Garmus’ debut novel “Lessons in Chemistry.” Elizabeth’s surprise platform? The set of 1961’s hit TV cooking show “Supper at Six,” of which she is the reluctant host.
In fact, it’s chemistry.” These words may not seem revolutionary today, but 60 years ago the suggestion that an element of women’s work could be approached with the rigor of a laboratory experiment was bold indeed.
Will consumers be mindful about the relative impact of different EV vehicle options? If you size up CO2 emissions over a vehicle’s lifetime, electricity soundly beats internal combustion – especially as more power is renewably sourced and battery technology gets “cleaner.”High gasoline prices turn heads toward EVs, which can lead to a hunt for affordable EV models. (The EV “high end” keeps getting higher.)The EV story, analysts point out, remains one of net carbon impact. An editorial in the Los Angeles Times decries a wave of bigger – and bigger-battery – EVs. Those are pricier than EVs like the little Bolt hatchback, which General Motors discontinued in favor of pickups. They’re more resource-intensive, too. The demand side – that is, consumer preferences – plays an important role, too.There are full-size EV pickups that can power homes, and some drivers do need big vehicles.
For 2022, the firms involved in the mining and manufacturing for those accounted for 27% of Tesla’s total emissions, reports Quartz.But the supply side isn’t the only thing to consider as we think about EVs and making the future work. And such “Scope 3” emissions – including those of suppliers – represented the deepest part of the product line’s carbon footprint.Batteries are a big factor. But this time, in Tesla’s report, it was part of the tally. What should we make of a recent report from carmaker Tesla reminding us that, even though its cars have no tailpipes, there are significant carbon emissions associated with getting them built and on the road?It’s worth thinking about, though there’s a lot more at play when it comes to electric vehicles and CO2 emissions.The vast network needed to supply raw materials and component parts for EVs makes for difficult accounting.
