“If 0 1% f th bl il bl ithi th ld• “If 0.1% of the renewable energy available within the oceans could be converted into electricity it would satisfy the present world demand for energy more than five times over.”

UK Marine Foresight Panel, 2000

“B 2030 45% dditi l ill b i d t t th d f th• “By 2030, 45% additional energy will be required to meet the needs of the world’s population.

Up to 67% of our current electricity comes from fossil fuel. p y

CO2 emissions could rise by as much as 45%.

OCEAN ENERGY HAS AN ESSENTIAL ROLE TO PLAY IN RESPONSE TO INCREASING ENERGY NEEDS AND CO2 REDUCTION.”
