Wave Energy is being developed for a long time almost since the 1700s through a variety of devices and convertors.Wave Devices are being used mainly to generate electricity and for water desalination.Wave Energy has a myriad of systems being developed as the technology is still immature.Wave energy generation is still a research field and there are as many designs as companies active in this field.Note as a technology matures,a single technology system gain ascendance as others are discarded along Darwinian lines.For example solar technology which is in the phase before maturity has majority of its energy convertors of the mainstream polycrstalline solar panels.Wind Energy which is further along the learning curve has most of its energy being generated from large vertical axis wind turbines.Wave Energy on the other hand has not come around a single dominant type of device.A number of devices are being developed to harness wave energy efficienty and at low cost.Wave Energy faces problems of being exposed to strong weather elements therefore wave energy designs are progressing along the lines of devices which require low maintainance and which are able to withstand weather better through devices with lower number of moving parts.
