Are you being deliberately obtuse? If not, in common parlance "renewable" implies Solar / Wind / Hydro / Nuclear (this one depending on who you ask), while non-renewable = fossil fuels.
If you have a drilling machine powered by diesel it is impossible for that machine to be "fully renewable" in terms of its power source. If you have a drilling machine that is powered entirely by electricity then it can be 100% powered by renewables, but yes as GP pointed out "can be" doesn't mean "is", but still if you care about such things you should obviously prefer the fully electric solution.
- stevenjgarner 4y agoYou're right. I was just stunned at the 1.38 gigawatts for a "stage 3" system (including "mother rig" + "father rig") for just a 10-m (33-ft) tunnel.
- preisschild 4y ago1.38GW is insane. The APR-1400 pressurized water reactor outputs 1.4GW, but at this point you would have a huge nuclear power plant to just power a single tunneling operation.
