This is my first blueberry wine and I thought I had all the ingredients but found out I was missing yeast energizer is there anything I can use instead
Have you already pitched the yeast? If just started, maybe you could cool things off to slow the fermentation's start long enough to overnight some energizer.
Does your recipe also call for yeast nutrients?
Good. Keep it cool until you hear from the fruit wine makers. They will be able to help you.
