I am not wishing to disagree that some silly decisions are taken, but there is also some interesting engineering going on because of despite that.
Newer really big earth moving kit is already moving or moved to be diesel electric, (traditionally it is/was diesel hydraulic) and has been making a transition for a decade or so, so at least the electrical drive train and controls is already a solved problem. Just replace the genset with a big enough battery...
As of early last year, there were actually some interesting experimental attempts at all electric digger and an all electric dumper truck I'd be the first to agree this is very low TRL stuff, pretty experimental and the thing that is amazing is more that it can be done at all, not that is is particularly well done, yet.
