at some point we will figure out that because we took some much energy out of earths core that it stops spinning and causes the magnetic field to collapse ;-)

- Retric 11mo agoNot really how that works. Also earths core is being heated from nuclear decay and tidal effects. It’s getting 10’s or TW worth of heat until the sun expands and eats the earth. https://en.wikipedia.org/wiki/Earth's_internal_heat_budget https://en.wikipedia.org/wiki/Earth's_internal_heat_budget
- danans 11mo agoI think they meant that as a joke.
- fanatic2pope 11mo agoThanks for that wikipedia link, it's fascinating!
- zdragnar 11mo agoThe world's total energy consumption (most of which is fossil fuels) is currently estimated at 620 exajoules, or 17TWh / year. Assuming zero growth in energy consumption (hello AI), extracting even half of that seems like it would be consequential.
- Retric 11mo ago10 TW * 1 year = 8,760 TWh / year. The current rate of energy production is ~42TW and slowly dropping over billions of years, so even after efficiency losses gathering 1% of what’s produced is several times current energy consumption.
- dbeardsl 11mo agoI believe this is off by 5 or 6 orders of magnitude. Looks like it's more like 200,000Twh / Yr https://ourworldindata.org/energy-production-consumption https://ourworldindata.org/energy-production-consumption
