Fate points are generally earned and spent by compelling and invoking aspects.
Fate points can also be earned by conceding in any situation if deemed reasonable by the Game Master. For every consequence you take during any situation (to mitigate stress), if you conceed the encounter you will gain that many fate points.
For example, taking two consequences and conceeding will have you loose the encounter but gain two fate points. The fate points earned are based on the number of consequences taken, not their severity.
