For a glimpse of what New York’s just-announced clean energy standard could mean to the state’s economy, look West.
A federal plan to offer leases for offshore wind power development near the coastline of Oahu could help Hawaii take a big step toward reaching its goal of generating all its electrical power with renewable energy sources by 2045. Stationing giant turbines in the ocean north and south of the island will be a huge engineering challenge.
The concept was invented by sailing enthusiasts Niels and Keld Hansen in 2000. The challenge was to create a regular output of energy from ocean swells and waves that are 5-10 seconds apart. This was achieved with a row of half-submerged buoys, which rise and fall in turn as the wave passes, forming the iconic part of Wavestar’s design. This allows energy to be continually produced despite waves being periodic.
