Battery Derangement
Stolen from another newsgroup
For those who think that EV's will "save" the "environment": https://www.city-journal.org/electric-vehicle-batteries Battery Derangement Electric vehicles wont save the planet and wont survive without subsidies. Mark P. Mills October 10, 2019 "Electric vehicles stand at the center of every €śgreen energy€ť initiative. Multiple jurisdictions mandate and subsidize the inevitable transition to €śclean€ť transportation. Some policymakers have gone further, setting deadlines for outright bans on the internal-combustion engine (ICE), and Green pundits regularly issue forecasts promising the imminent dominance of electric vehicles (EVs). The EV is central to the notion that were on the cusp of a grand shift to a €śnew-energy economy.€ť In addition to its putative environmental benefits, the EV, were told, is a better machine than an ICE. Its easier to manufacture, uses less labor, and will€”eventually€”cost less. Since consumers will soon demand an all-EV future, we should embrace policies to accelerate the transition. Rarely have so many claims about a product been so wrong. The only unequivocal fact in the EV narrative is that more EVs exist today€”approximately 4 million€”than ever before. Lithium-battery chemistry€”the inventors of which received the 2019 chemistry Nobel Prize€”along with advances in power electronics, has made it possible to build practical, if expensive, electric cars. But everything else in the popularized EV storyline is deeply misguided. Advocates claim that EVs are far simpler machines than combustion engines. But the essential €śengine€ť for both is similarly complicated. While the EVs electric motor is simple, its battery is a half-a-ton electrochemical machine with thousands of parts and welds, along with wiring, electronics, and cooling. Its every bit as complex as€”and far more expensive than€”the combustion-mechanical drivetrain that it replaces. Manufacturing automotive batteries is surprisingly labor intensive. Teslas gargantuan battery factory in Nevada produces about 1,000 propulsion batteries per year per 12 workers. Meantime, a modern engine and transmission factory produces about 1,000 mechanical-propulsion systems per year per four workers. EVs dont reduce total labor requirements; they simply outsource American labor. Since most automakers arent capable of fabricating batteries, EV-battery jobs reside mostly in Asia. China alone produces 60 percent of the worlds lithium batteries. Theres no prospect of creating a domestic EV supply chain anytime soon, regardless of incentives. To EV enthusiasts, U.S. job losses are beside the point because ending our reliance on fossil fuels and saving the planet takes precedence. But it requires the energy equivalent of about 100 barrels of oil to fabricate one battery capable of storing the energy contained in a single barrel of oil. Importing batteries manufactured on Asias coal-heavy grid means that consumers are just exporting carbon-dioxide emissions, along with jobs. It takes years to offset those emissions when the EV is plugged into our real-world power grid, where coal and natural gas still account for 70 percent of electricity generation. Then theres the array of primary minerals€”lithium, cobalt, manganese, carbon, nickel, copper, aluminum€”needed to produce a 1,000-pound automotive battery. Accessing the necessary minerals for that one battery entails mining, moving, and processing some 500,000 pounds of raw materials. Embracing batteries at automotive scales would lead to an unprecedented global expansion in mining, with all the accompanying negative environmental effects that tend not to be palliated in developing countries. None of this seems to concern China, which boasts 60 percent of global EV sales. There, the EV supply chains labor intensity is a feature, not a bug. After all, Western nations have largely given up on the related manufacturing, as well as materials-mining and chemical-refining industries. China has spent $60 billion cumulatively in domestic subsidies in order to become the dominant global player, but it ended the EV gravy train this year, cutting subsidies by 65 percent, with plans to eliminate them entirely next year. The result? Chinas vaunted EV sales growth went negative. Having abandoned direct subsidies, China will now simply require that EVs make up 3 to 4 percent of all domestic car production. Policymakers in democracies and autocracies find mandates appealing because they are a de facto hidden tax wherein industries, rather than government, get blamed for resulting higher costs. Mandates and bans can enhance EV sales for as long as markets and consumers tolerate them. But that approach makes a lie of claims that €śEV sales are accelerating.€ť Capitulating to a mandate, much less one set to a mere 4 percent, means that were miles away from seeing a new-energy transportation system. Sales data show what consumers actually want. Light trucks€”SUVs and pickups€”make up 70 percent of all vehicle sales in America. This trend accelerated after the Great Recession, during a period of supposedly rising €śclimate awareness€ť and the emergence of the millennial car buyer. There isnt a battery option for SUVs at a price that consumers, rather than governments, will pay. The few successful EV-SUVs are strictly for the 1 percent crowd. In reality, 96 percent of Americas consumer vehicles are gasoline-fueled ICEs, and 3 percent have the diesel option, the latter outselling electrics. The ratios are similar globally. Odds are the EV option will eventually do far better than the venerable diesel, but the jury is out on how much better. And arithmetic reveals that even a 100-fold growth in EVs wouldnt displace 10 percent of world oil. In one of historys ironies, the Tesla Model S was introduced in 2012, exactly 100 years after Studebaker ended production of its lineup of electric cars. Back then, EVs had dominated car sales for nearly 25 years. Its taken one century since then to invent a useful battery. But an EV is still a car with the same features consumers focus on when making buying decisions: body style, paint, seats, cup-holders, cool touchscreens, and so on. Changing a cars fuel source is about as revolutionary as changing the feed for a horse. Choosing a battery over an ICE isnt a revolution. Its an option€”an expensive one€”that reduces neither total labor nor environmental impacts..." Mark P.
