It's not negligible for its weight. You can always scale up an electric motor. The largest machines in the world (such as bucket wheel excavators) are driven by electric motors. Additionally, electric motors are much simpler to cluster into a distributed propulsion configuration than jet turbines are. That's why NASA's building the X-57 electric aircraft.
