OCEAN ENERGY: RENEWABLE ENERGY

TYPES OF ENERGY THAT OCEAN ENERGY CARRY

• MECHANICAL ENERGY

• WIND ENERGY

• SOLAR ENERGY

• THERMAL ENERGY

HOW IS WIND ORIGINATED OR GENERATED?

WHY IS OCEAN ENERGY PREFERABLE COMPARED TO SOLAR AND WIND ENERGY?

WHICH IS/ARE TRUE ABOUT OCEAN ENERGY

• DOESN'T PROVIDE ARTIFICAL REEF HABITAT FOR SEA LIFE

• HIGH MAINTENANCE AND OPERATION OF THE FACILITIES

• HAVE EFFECT ON MIGRATORY FISH PATTERNS OR COASTAL ECO-SYSTEM

• LEAST DEVELOPED RENEWABLE ENERGY

• PRODUCE CHEAP COST OF ELECTRICITY

OCEAN ENERGY IS SAID TO HAVE HIGHER POWER PRODUCTION; WHY IS THAT?

LONGITUDINAL WAVE IS DEFINED AS

• DIRECTION OF WAVE PARTICLE IS IN 90 DEGREE TO PROPOGATION OF WAVE

• DIRECTION OF WAVE PARTICLE IS PARALLEL TO PROPOGATION OF WAVE

• DISPLACEMENT OF PARTICLES PRODUCES DISTURBANCE WHICH IS TRANSFERRED TO ANOTHER PARTICLE TILL ALL HAVE SUFFERED GREATER/ LESS DISPLACEMENT

SEA WAVE OR LIGHT WAVE IS CONSIDERED AS

• TRANSVERSE WAVE

• PROGRESSIVE WAVE

• LONGITUDINAL WAVE

• STATIONARY WAVE

DEFINE THE HOSTILITY OF THE OCEAN ENERGY

• HIGHER ENERGY DENSITY

• RANDOM BEHAVIOUR OF THE SEA

• PREDICTABILITY OF THE OCEAN ENERGY

• HIGH CORROSION LEVEL OF SEA WATER

• LARGE ENERGY STORAGE

WHICH OF BELOW DESCRIBE OFFSHORE DEVICES?

• DEEP WATER DEVICES SUCH AS WAVE ATTENUATOR OR POINT ABSORBER ARE USED

• THE DEVICES ARE SUBMERGED IN THE SEA

• NO NEED FOR SIGNIFICANT COASTAL EARTH WORKS

• FIXED IN THE SHORELINE

• DEPTH OF WATER IS SHALLOW
