Even if you consider open source, the majority of contributions are from US companies.
There are some companies contributing to GCC and clang from UK, GraalVM and V8 are partially in European sites but from American companies nonetheless.
There is OCaml in France, more no idea.
Europe is not Germany.
Electricity price is 2-3x times more expensive in Germany.
Electricity price for electricity intensive professional is around 12-14cts/kWh in France and can be reduce under 10cts/kWh for big consummers.
Which is competitive with the cost in several US states (it is still higher than Texas but not 3x).
Nordic countries should be able to align on that too.
Make sense.
Production price in Europe is between 3.5-4.5cts/kwh averaged. The rest are mainly transport and taxes.
If the EU currently choose to exonerate industrial consummers from these taxes and offload them on citizen (which honestly make sense from a business perspective), they could currently beat most US states in term of pricing while providing lower carbon footprint/kWh
Power matters, but what matters is power availability not cost.
