- Wave and tidal devices convert the energetic movement of the waves, and the rise and fall of the tides, into electricity via internal generators.
- The electricity is transported to shore via underwater cables.
- Wave devices are either floating or fixed to seabed or shore.
- Tidal projects use tidal barrage (similar to hydro dam or underwater turbine generators)
- Scotland has more than a quarter of Europe’s potential wave and tidal resources!
- Some of the best resources are located off the north-west coast and northern tip of Scotland
- Around the coast of the UK the sea levels rise and fall twice daily.
- The Pelamis Wave Device was developed & manufactured in Scotland
- Pelamis is greek for sea snake!
- Wave and tidal energy is freely available.
- Once installed running costs are very low.
- No fuel is required.
- No waste or pollution is produced.
- Wave energy is capable of producing large amounts of energy.
- With tidal energy the amount and time when electricity produced is very predictable.
- Developing and testing technology in the sea can be expensive
- Wave devices can be hazardous for ships and leisure craft
- Difficult to find suitable locations for tidal power
- Tidal devices can affect sea life
- None in Aberdeen City and Shire, but the European Marine Energy Centre in Orkney and the Wavegen Limpet project at Islay.
