There is a precedent for electric equipment. (Edited from wikipedia)
Big Muskie was the world’s largest electric shovel, used for strip mining coal in Ohio. It was the only machine of its kind and was so massive; it could remove 240 tons of coal in a single scoop. It was powered by electricity supplied at 13,800 volts via a trailing cable, which had its own transporter/coiling units to move it.[1] The electricity powered the main drives, eighteen 1,000 horsepower (750 kW) and ten 625 horsepower (466 kW) DC electric motors. Some systems in Big Muskie were electro-hydraulic, but the main drives were all electric.[3] While working, Big Muskie used the equivalent of the power for 27,500 homes, costing tens of thousands of dollars an hour just in power costs and necessitating special agreements with local Ohio power companies to accommodate the extra load. The machine had a crew of five, and worked around the clock, with special emphasis on night work since the per kilowatt-hour rate was much cheaper.

There is no way we have the generation capacity now or in the near future to power all of this stuff.

Sorry, I get side traced sometimes.
Don't apologize! Side tracks are like candy for those who like to learn new things.

Big Muskie was doing it's thing not too far from here and I had the opportunity to see it working before they shut it down. It sounded like Godzilla and had a crew of welders working to hold it together. The power cable was huge. Sadly, the only thing left of it it now is the bucket.
