WHY RENEWABLE ENERGY?
• Reduction of emissions, Kyoto targets• Security of supply• Cost
MARINE ENERGY
• Tidal Barrage • Tidal Stream• Wave Energy
– Shoreline– Seabed– Shallow water– Deep water
WHY IN SOUTH WEST?
• Strong wave and tidal resource• Existing marine sector• Academic base• Opportunities in new industry
