[Knowledge] Use and Recovers Energy

Gathering consumes energy. Talking to specific NPCs or exchanging items also requires energy. You can increase Item Drop Rate by consuming energy at a connected node, or use energy to check market prices for trade items of traders far away.
1 consumed energy is recovered every 3 minutes, but you can recover energy quicker with the Energy Recovery +O buff or by laying in bed. You can also recover all consumed energy at once by using Energy Tonic items.
