Awk While and For Loop - bash

Question

I have two files (file1 and file2)
file1:
-11.61
-11.27
-10.47
file2:
NAME
NAME
NAME
I want to use awk to search for first occurrence of NAME in file 2 and add the 1st line of file1 before it, and so on. The desired output is
########## Energy: -11.61
NAME
########## Energy: -11.27
NAME
########## Energy: -10.47
NAME
I tried this code
#!/bin/bash
file=file1
while IFS= read line
do
# echo line is stored in $line
echo $line
awk '/MOLECULE/{print "### Energy: "'$line'}1' file2` > output
done < "$file"
But this was the output that I got
########## Energy: -10.47
NAME
########## Energy: -10.47
NAME
########## Energy: -10.47
NAME
I don't know why the script is putting only the last value of file1 before each occurrence of NAME in file2.
I appreciate your help!
Sorry if I wasn't clear in my question. Here are the samples of my files (energy.txt and sample.mol2):
[user]$cat energy.txt
-11.61
-11.27
-10.47
[user]$cat sample.mol2

Answer 1

paste -d "\n" <(sed 's/^/########## Energy: /' file1) file2
########## Energy: -11.61
NAME
########## Energy: -11.27
NAME
########## Energy: -10.47
NAME
Or, sticking with awk
awk '{
print "########## Energy: " $0
getline < "file2"
print
}' file1

Answer 2

Using awk:
awk 'NR==FNR{a[NR]=$0;next} /#<TRIPOS>MOLECULE/
{print "########## Energy: ", a[++i]}1' energy.txt sample.mol2
Explanation:
FNR - line number of the current file
NR - line number of the total lines of two files.
NR==FNR{a[NR]=$0;next} is applied for the first energy.txt
so above statement populates an array with index as 1,2,3... and value as $0
/#<TRIPOS>MOLECULE/ search is executed on the 2nd file sample.mol2
When above search is successful it prints quoted static string and a line from array created from 1st file
++i moves the counter to next element in array after printing
