LightningFE

When lightning hits a Lightning Rod, the modified rod pushes its full energy burst into neighboring blocks that expose the NeoForge Energy capability in a single tick. Any energy a neighbor cannot accept at that moment is discarded rather than stored. The result is a high-amplitude power source whose output depends on the surrounding infrastructure, since only a system with enough capacity captures much of it.

Low-tier energy systems capture little of each strike, while high-throughput systems capture more. Because the impulse arrives as an event rather than a steady flow, a generator built on LightningFE must try to smooth the output itself. The mod is intended to reward proper energy intake infrastructure, and it deliberately wastes whatever excess a system cannot take in. Outside energy emission, the rod keeps its vanilla behavior.
