Describe the feature
When a craft is started and there is not enough energy to perform the action in ae2, send a chat message to the player stating the network needs more energy. The same would apply if a player tries to remove an item from ae2 and can't due to power demand.

Reasons why it should be considered
This can help with players that slowly run into power demand issues.

Additional content
For players that have channels enabled the controller could change colors if the network is under 10% energy.
