Is it good to have an energy funds available?

If I'm understanding correctly, you are asking if it's good to have emergency funds available if you need it? I definitely recommend having emergency funds, even if it's just $50 or $100. I was not taught anything like this when I was young and wish that I had. Now I am older and I have a container that I put change in. I also have another container that I put dollar (any denomination) in. I never spend my $1 bills after I break another bill. They go straight into the container. If I open my wallet to take out $1 bills and there are several in there and I also happen to have a $5 bill, I will also take that out and put it in my container. I did this for a year and when I counted it, I had almost $400! You never know when you're going to need something extra or something completely unexpected comes up and having even a portion of what you may need will still help lower the stress of a situation.
