$CWGYF From Parker-Hannifin Corp NYSE: PH "2021 Power Generation and Renewable Energy Trends" discover.parker.com/Power-G... Under Wave Energy: "Ocean wave (hydrokinetic)energy has THE POTENTIAL TO BE THE WORLD’S LARGEST SOURCE OF RENEWABLE ENERGY FOR ELECTRICITY GENERATION, [emphasis mine] but it is the least developed. Prior to the pandemic,the global market for wave power energy was forecast to grow at an annual rate of 10.2% between 2017 and 2023." "This industry is still evolving, with numerous Wave Energy Converter (WEC) technologies being tested and no clear winner. This has been one deterrent to attracting private investment. The European Marine Energy Centre lists 255 different WEC devices and their developers, most from Europe, the U.S. and Australia. " Under Hybrid Systems it mentions Carnegie... without mentioning Carnegie: "A project being developed in Western Australia will incorporate wave energy, a solar farm and a battery storage system." Great resource.
