An embodiment for generating energy from a fluid flow is proposed. A corresponding energy generation system includes energy conversion means, sail means switchable between an active condition for being carried away from the energy conversion means by the fluid flow and a passive condition for minimizing said carrying away, connection means for connecting the sail means to the energy conversion means, the energy conversion means generating said energy when the sail means in the active condition is carried away, return means for returning the sail means in the passive condition towards the energy conversion means, and switching means for switching the sail means to the passive condition and to the active condition in response to a maximum distance and to a minimum distance thereof, respectively, from the energy conversion means. In an embodiment, the sail means includes a pair of sail modules slidable along the connection means, each sail module being individually switchable between the active condition and the passive condition; the switching means then includes stopping means for each sail module, the stopping means being adapted to stop the sliding of the corresponding sail module in the active condition when carried away thereby causing the switching thereof to the passive condition, passive locking means for each sail module, the passive locking means being adapted to lock the corresponding stopped sail module in the passive condition, coupling means for sliding each sail module locked in the passive condition in opposition to the fluid flow to a standing position along the connection means by the other sail module in the active condition when carried away, and active locking means for each sail module, the active locking means being adapted to lock the corresponding sail module in the standing position thereby causing the switching thereof to the active condition after the unlocking from the passive condition.
