Newcastle started the game strongly and were clearly determined to make amends after their derby thrashing by Sunderland last weekend.
Pardew said: "The energy levels we had on Sunday were not good enough to cope with that Sunderland performance.
"We needed to show today, after we get some rest, that we ain't a bad team.
"First half we really should have put the game to bed - we had two or three good chances at 1-0 and we were coping really well with West Brom.
"But they went direct in the second half and with their powerful strikers, we had to show another part of our game, to roll our sleeves up and defend. We did a good job of that.
"The overall feeling is we have shown exactly what we needed to show today without getting the three points."
