Resources
When Do Unused Energy and Power Disappear?
Keep unused resources until a Rune Pool emptying point: the start of each Main Phase or the end of each turn.

The short answer
Your Rune PoolThe temporary supply of generated Energy and Power waiting to be spent, not the physical Runes in your Base. Every player's pool empties at the start of each Main Phase and at the end of each turn; this removes unused resources, not Rune cards.View in Glossary holds generated EnergyA resource used to pay numeric Energy costs. Energy has no domain and is spent from your Rune Pool.View in Glossary and PowerA resource used to pay Power costs. Power normally has a domain that must suit the requirement; Universal Power can pay for any domain.View in Glossary waiting to be spent. It is not the physical Runes in your Base. Emptying the pool removes unused resources, not those Rune cards.
Unused Energy and Power stay available until you spend them or the pool empties. Every player loses all unspent resources at the start of each player's Main Phase and at the end of each player's turn.
The pool does not empty just because you finish playing a card or a ChainAn off-board zone that holds cards and abilities during the process of playing them. Cards and abilities on it are public information.View in Glossary finishes resolving. Resources made during the start-of-turn phases will not carry into the Main Phase.

EnergyA resource used to pay numeric Energy costs. Energy has no domain and is spent from your Rune Pool.View in Glossary pays numeric Energy costs. PowerA resource used to pay Power costs. Power normally has a domain that must suit the requirement; Universal Power can pay for any domain.View in Glossary pays Power costs, matching the required domain; Universal PowerPower that can pay a Power requirement of any domain. It is still Power, not Energy.View in Glossary can cover any domain. The two resources cannot substitute for each other.
At the start of the Main Phase, pools empty before start-of-Main-Phase effects happen. Resources added by those effects remain available afterward. At the end of the turn, pools empty after end-of-turn effects. You can use resources during those effects before any leftovers disappear.
In practice
Example
During your Main Phase, an effect Adds 3 Energy and you spend 2 to play a card. The remaining 1 Energy stays available for another payment that turn. If you leave it unspent, it disappears when the pools empty at the end of the turn.
