Name
edit'Muckle' is Scots for 'big' or 'large'; 'holm' is from the Old Norse holmr, a small and rounded islet.[4]
Geography
editTo the south lies Little Green Holm, and between the two is the Sound of Green Holms. Eastward is a strait called Fall of Warness between Muckle Green Holm and the much larger island of Eday.
Muckle Green Holm has a great cormorant colony and a population of European otters.[2]
Tidal power
editThe Fall of Warness has strong tidal currents suitable for tidal power.
Starting in 2007,[5] the European Marine Energy Centre installed tidal power testing equipment.[6]
In 2021, Orbital Marine Power installed a tidal turbine called Orbital O2 that supplies 2MW to the electrical grid.
