There are a huge amount of basic, low cost earphone manufacturers. The budget audiophile community can also provide more targeted help if needed, just be sure to include more info like price range, how you plan to use the headphones and what quality you expect, to get more helpful advice.

Little to none so far. This might change in the future, but not that quickly.
The additional renewable capacity added year on year is not enough to cover the additional electrical load, which originates mainly from 2 things: transport/infrastructure (including EVs, data centres, AI) & environmental loads (more heatwaves in populated cities, where people then need to cool).
As far as I understood, 2024 was a substantial year for the environmental side of the equation, otherwise additional renewables installations would have been able to cover just about all the additional power load.
