light post, green dumpster, train car, or other drained energy source
Easy energy:
Use your lightning bolt — which does not cost energy (ENG) — to charge a light post, battery, green dumpster, train car or another object that can be drained of energy. Drain it after it is charged. If the object does not explode, your entire energy meter will be refilled. OR shock a pedestrian, then walk up to them. Lock on, then repeatedly press Square to restore your power. After killing a person, shock their body with your basic lightning bolts that require no energy. Press L2 while they are sparking to absorb the energy and recharge.
Easy experience points:
Find a Dustmen Conduit in The Warren. They frequently spawn three small scorpion-like creatures that are easily killed. Find a safe location, like the top of a roof, where the Conduit cannot shoot you with his rocket launcher and the spawned creatures cannot reach you. Keep attacking the spawned creatures for easy experience points (XP).
