Collections that give you Energy and XP

There are a bunch of collections that give you more consumable energy in the same way as food does or the little lightning energy boosts you collect while harvesting things around the homestead. There are also some collections that raise the max upper limit of energy you can store in your energy bar. 

There are a few that give you XP points too!

You can also get wood, coins, items and boostsfrom various collections. See all available collections here.
