My suggestion would be something in the lines of

#!/bin/bash

for i in $(seq 2121) ; do
g_energy -f traj_${i}.edr -o ${i}.xvg <<< "${i} 0"
done

===

Notice the "in" keyword right after 'i'.

I used a subshell to invoke the program 'seq', which generates a
sequence from 1 to the given argument, so we don't depent om how these
other constructs with ((; ; )) work among different versions of bash.

I also suggest replacing the here-document by a here-string, but
that's personal taste. You may or may not have problems with older
versions of bash
