The higher trees/plants grew, the further their apical structures were from ground water sources, so the lignin-supported, strong vascular tissue (phloem) allows the transport of water against gravity, using a capillary method (benefiting from the adhesive effect of water molecules).

What is the source of energy that powers a hydroelectric power plant?

It is the potential energy stored in the reservoir water which is "released" as it is converted to kinetic energy (the movement of water which spins the hydroelectric generator turbine, etc.), but the absolute source of that original potential energy comes from the Sun's action to evaporate lake or ocean water which is returned to Earth as rain ... and it is this rainwater which ultimately fills the reservoir behind the hydroelectric power plant.
