WIND |
|
One of the most abundant sources of energy in Shetland is wind power. Weather conditions are favourable in Shetland for the production of electrical power from wind. It should be recognised that even with the use of additional insulation in buildings, the main heating demand is likely to arise during periods of strong wind. The correlation between wind strength, level of energy production and level of energy demand for heating, is what renders wind turbines an ideal source of energy for heating in Shetland.
1. To use the wind speed calculator click here
2. Type OS Grid Reference into ‘Grid-o-matic’click here (this calculates easting and northing)
3. Run ‘noable’ programme and put in easting and northing to find wind speeds at 10m, 25m, and 45m
More detailed wind records are held by the Met Office.
The British Wind Energy Association (BWEA) wind speed data base holds information on the average annual wind speed at heights of 10m, 25m and 40m at every grid location on the ordinance survey 1:50000 scale maps. This database has shown an estimated annual average wind speed of |

WAVE |
|
Ocean waves are a form of wind energy that is concentrated within surface seawater. Friction develops between air and water as wind blows across the water, and waves are produced as energy is transferred between these two elements. Taking the motion of the waves, and translating it into mechanical or electrical energy, generates energy from waves.
The UK is situated in the path of strong winds from the Atlantic, creating large waves. There is therefore the potential to exploit a great deal of energy from wave power. |

TIDAL |
|
| Tidal power generates electricity in a similar fashion to hydroelectric power. Water passes through turbines to generate electricity. |
