The Winds That Turn. The elemental winds are those that power magic itself. You gain a number of elemental points equal to your level. When casting a spell which causes elemental damage you may use elemental points to increase the level of the spell you cast. You must spend an amount of points that the spell would be taken to. For Instance;
A Genasi casts fireball at 3 level, they use elemental points to instead cast it at 4 level, in order to do so they must expend 4 elemental points.

Elemental winds. You may use the sorcerer meta magic rules. Exactly as described in Sorcerer, except it costs you 1 elemental point to use a meta magic effect and such effects can only be used on elemental based spells.
