Alphabet's yearly revenue is US$258 billion, some of which is earned from things like Google Play, Google Cloud, and Google Workspace, and some of which has been spent on things like Makani, Verily Life Sciences, DeepMind, and Google Fiber. Meta's revenue is US$118 billion.
https://www.globaldata.com/data-insights/internet-services-t... says, "Google earned nearly 81% of its total revenues in 2021 from advertisements," and it's talking about that US$258B number, not some smaller number that excludes other Alphabet companies.
We can maybe estimate the whole adtech spend, generously, at US$400 billion per year [edited: was US$300 billion]: most of Alphabet, all of Meta, plus a handful of smaller fish. (I say this is "generous" because it's counting all the effort that goes into running Google Search, YouTube, Instagram, and Android development as "adtech", because it's monetized through ads, even though most of the people working on those projects are not directly concerned with ads; if you omit that, you might size adtech at only US$50 billion.) And maybe US$200 billion per year goes into the renewables transition. I'm not convinced that doubling that to US$400 billion per year would guarantee a win, particularly when the humans are going around bombing each other's power plants, snarling up power plant construction and energy-efficient housing in red tape, and publishing disinformation that "debunks" global warming.
These are of course very rough estimates, but how would you estimate these numbers?
As far as I know, there aren't any invaders the humans are fighting; they're only fighting other humans, plus the occasional rogue elephant.
Invasion is an activity, not an identity. Those so engaged could stop anytime. Many will.
Apparently it has not had that effect in Romania, yet. But they are by report still happy with their Canadian CANDU reactors.
