This combo happened for me tonight. If we'd played that I was able to get back the printed energy cost, I could have just churned Keep cards, gaining a huge amount of energy. Instead, we played that I got back what I paid; I still churned a number of cards (somewhat useful), but didn't get to rake in extra energy.I think that the key phrase is "receive the energy they were purchased for." Otherwise, you get this situation: churn Keep cards as long as you're able, sweep when there's nothing buyable, and buy points cards to win the game (or get close). That doesn't seem in the spirit of the game.
