INTRODUCTION TO HYDROPOWER
Hydro means "water". Hydropower is "water power" and
hydroelectric power is electricity generated using water power.
Egyptians harnessed energy from flowing water 2,000 years ago
Hydropower is the most widely available renewable energy
19% of all electricity used around the world
