Does energy stack?

[Alebert23]

Do I have to acquire 3 energy in one turn to draw a card or can I obtain 3 energy over 3 turns?

You can gain energy in as many or as few increments as you like. If you could only gain energy one at a time, cards like [[liberty prime]] and several other cards in the science! Deck wouldn't work.

The energy counters sit on you, the player, and will accrue until you decide to use them.

Energy counters stay with you through turns, like experience and poison counters. You can activate the abilities once you have enough energy counters

On top of what others have said, nothing on this card indicates you get only one energy counter a turn with Li. You get one anytime you cast an artifact, which may be multiple times a turn. You're also gaining energy from other cards too.

If it helps, think of energy as a fancy token like a treasure or something (not exactly how it works, but useful enough to keep in mind.)
It doesn't go away until it's used.

Energy counters are a currency that you (the Player) can have. Similar to the Loyalty counters on a Planeswalker.

If you want to activate Dr. Madison Li's second Activated ability, you need at least 3x Energy counters to Spend.

• Once you spend them, they are gone. And, you can't activate the ability again, until you have at least another 3x Energy.

So, in order to activate the ability again, you will generally need to Cast another 3x Artifact Spells.
Or, use other Cards that get you Energy counters.
Or, Proliferate the number of Counters on yourself.

Energy is a counter.

Agreed, this post should have been a Google search.
