A battery does not produce anything. It does store and deliver electrical energy though.
The electrical energy it stores was produced by many things including, fossil fuels, coal, solar and wind. All being wildly different from each other when it comes to efficiency and cost.
What Henry is saying is that you don't generally call a cordless or battery powered drill an "electric" drill. Anything that gets its power from a battery will always be limited to the batteries storage and transfer limitations.
A corded drill would generally be called an "electric" drill and will be considerably more powerfully because it doesn't have to work within the batteries limitations.
TLDR
If someone told me to grab them the electric drill, I would bring them back the one with the cord on it.
