OVERVIEW
Hydropower energy production has increased globally in the past decade. China, Canada, Brazil, USA, and Russia are the top five users of hydropower. Hydropower plants produce approximately 24% of the world’s energy used. The US has over 2000 hydropower plants in operation. Technology gives us the ability to capture and use the stored energy, available in large bodies of water, to create electrical energy.

THE GROWTH OF HYDROPOWER Hydropower is created by water flowing through large dams. The energy produced is connected to a powergrid. Hydropower plants do not generate energy ata level sufficient to replace energy produced by coalor nuclear plants. Hydropower plants generate energyto supplement energy produced by coal and nuclear energy plants.

Generator
HYDROPOWER THEORY OF OPERATIONWhen the control gate is raised, water from thereservoir flows through the intake and penstock. Water pressure increases as it reaches the turbinewheel. The turbine wheel turns and drives a shaft onthe generator. Electrical energy is produced by thegenerator and is fed from the transformers to thepower grind through the power lines.
