Some differents way to produce marine energy.

1. Marine Energy
How can we use marine energy?

2. I) Problematic:
• Today:
• Problem of pollution (greenhouse gas…)
• Fossil energy is not inexhaustible
• Climatic warming
• We should start to use others energy
• Consumption of energy is always growing
(population grow…)
• Solution
• Wind energy
• Sun energy
• Marine energy

5. III) Other means of use marine energy
a) Ocean thermic energy

To make island
independent.
It base on
thermodynamic
principle :
With two thermic
source we can create
a mechanical work.
