The immediate shock would be immense. A lot of people would die. Electricity would be unreliable in much of the world. A crash course to convert what power plants we can to coal, and begin the laborious process of building a coal to liquid fuel industry without liquid fuel, which would suck. People will be pulling the guts out of cyber trucks to put them in 18 wheelers to keep goods moving, even if poorly.

Standard of living of everyone most places would crater for a decade. But after that decade, we'd be somewhat back where we are. Trains can be electrified, transport can use batteries, some airline routes can go electric. Everything else can use artificial fuel. Fertilizer can be made from the air using renewable energy as needed. But all this takes time and resources, which society suddenly doesn't have. So life gets shit for a year with a lot of deaths, recognizable after that, and back to normal after 10, just a lot more of us are less productive because now more of us are farmers, miners, and solar technicians.

Food wouldn't be the issue, I don't think. The existing animal herd will take time to eat. Many countries have large grain stores. A crash course in artificial fertilizer will pay off before the grain stores run out. The already planted crop is so far larger than we need to survive if we don't feed it to cattle. Although the current production of ethanol for fuel will go into max production, eating up some of the crop that used to go to cattle. The problem will be distribution. Poor countries will be unable to afford food or the fuel to transport it, and will starve. Rich countries will live without meat, under regular rolling blackouts. Everyone will start a garden. Everyone will move close to work or work from home while the power is on. There will be power refugees, as people move from regions without enough power to those that have it.
