Some triggered abilities state that you "may pay" a certain amount of energy . You can't pay that amount multiple times to multiply the effect. You simply choose whether or not to pay that amount of energy as the ability resolves.

If an effect says you get one or more energy , you get that many energy counters. To pay one or more energy , you lose that many energy counters. You can't pay more energy counters than you have. Any effects that interact with counters a player gets, has, or loses can interact with energy counters.

Some spells and abilities that give you energy may require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. You won't get any energy .
