ALTERNATE ENERGY

Hydroelectricity is a word that refers to electricity generated by hydropower

I chose this because I would like to know more about it as I have not learnt much about hydroelectric energy before and it seems like a interesting topic to study

POSITIVES

• It is cheap after it's built
• Easy to make energy
• When the dam has been constructed energy can be formed constantly
• And at a extremely fast rate
• When electricity is not needed the damn gates can be closed

POSITIVES

• The dams last for many decades
• The lakes behind the dams can be used for water sports
• Some of the dams become tourist attractions
• The build up of water means energy can be stored until needed
• The energy does not polute the air

NEGATIVES

• The dams are expensive to build
• To make a profit they must operate for a long time
• Building the dams can cause geological damage
• some people must move out because of the dam construction
• Some of the natural environment is destroyed

Where In the World?
The largest hydroelectric stations are located in:
China, Hubei, Brazil and Paraguay

Also in Australia there are over 100 operating hydroelectric power stations
