Sure if we could magically transport and store it. Like we can for liquid fuels.

No magic required: the tech for transporting electricity predates writing, and that by about six millenia; while reusable storage was only about 27 years after dynamo generators, 1859 vs. 1832.

Both have since been improved upon somewhat.

What are you referring to? Copper?

[ben_w]

Mostly, but gold and silver are also simultaneously antiquity-era metals and great electrical conductors.

No generators to connect to a power grid, nothing to use the power for, but they could still transport electricity in the time before writing.

Magically transporting and storing liquid fuels involves an unbelievably massive supply chain of trucks and refineries and storage tanks and gas stations.

If we need infrastructure to make use of energy we can ‘magic’ it up.
