Energy Type: Hydroelectic (moving water) Source: Water Sarah Stein How its this energy transfered?


 * 1) Dams are built to trap water in
 * 2) Water is allowed to flow though tunnels in the dams
 * 3) Turns turbines and drive generators
 * 4) Electrons turn on and make the energy

How is this energy used today?

~ Hoover Dam ~ Niagra Falls
 * Water dams

Advantages
 * Energy is virtuall free
 * No waste or pollution produced
 * More reliable than wind, solar or wave power
 * Hydroelectric power stations can increase to full power

Disadvantages


 * Very expensive to build dams
 * Can flood a big area
 * Suitable site can be difficult to find
 * Water qualitie and quantity downstream can be affected
 * Can have an impact on plant life

This energy sorce is renewable. The sun provides the water evaporations from the sea.
