Which of the following is true?A. For wave energy conversion, there are three basic systems: channel systems that funnel the waves into reservoirs; float systems that drive hydraulic pumps; and oscillating water column systems that use the waves to compress air within a container.B. A barrage converts tidal energy into electricity by creating thermal energyC. Wave energy can be converted into electricity through offshore systems onlyD. Tidal Barrages work rather like a hydro-electric schemes  None of the above  A & D  B & C  All of the above

Which of the following is true?A. The capture of energy created when salt water and fresh water meet is known as osmotic power.B. Ocean Thermal Energy Conversion (OTEC) is a process that exploits the natural temperature difference between the surface and the depths of the ocean.C. At least 25 countries are involved in ocean energy development, and wave and tidal technologies saw significant progress toward commercial generation during 2010.D. The world's first commercial-scale tidal turbine (1.2 MW) passed the milestone of providing 2 GWh of electricity to the U.K. electricity grid in 2010  A & B  All of the above  A & C  None of the above
