1. Did you try it. (hint: delete your debug.txt and open it after each error)

I dont understand ("delete your debug.txt and open it ")

He means to delete the file debug.txt from your bin directory. Then start up a game of minetest and when the error happens, open the newly created debug.txt and very near the bottom of the file will be some error lines if there are errors.

You are trying to define an item in the default mod namespace. You can't do that.
If your mod is named 'mymod', use "mymod:energy_pickaxe"
