There’s still a selection bias towards technically literate, privacy-conscious, left-of-center (or at least liberal) people. Lemmyverse represents such an unthinkably tiny fraction of Earth’s populace it’s not even an echo-chamber, it’s more like an echo-pocket. However, this allows me to feel comfortable here, which is a huge plus. You just have to keep in mind that every opinion that’s popular here is not representative of anything but the Lemmyverse.
The article is very light on details, but the numbers don’t seem to check out at all. Back-of-the napkin math (assuming a square 1km × 1km solar array and total sun luminosity of 3.83e26 W):
1 km ^ 2 * (3.83e26 W) / (4 * π * (1 AU) ^ 2) * 1 year to TWh ≈ 11.94 TW·h
This is a “measly” 12 TWh of TOTAL energy delivered to the array over a year - not accounting for solar panel efficiency losses (20-24%) or the elephant in the room of transmitting this energy back to earth. For context, China alone consumed around 39 PWh (39000 TWh) of energy from fossil fuels just over the course of one year, 2023. The entire world consumed 55 PWh (55000 TWh) of oil energy in 2023 alone. It’s not even comparable to the annual consumption of oil. If we consider the aforementioned factors, assuming 24% solar panel efficiency and an extremely generous 50% power transmission efficiency, we get:
Which is literally nothing on a national scale - it’s less than a percent of the Three Gorges Dam output.
