New technology which uses ocean waves to generate electricity could help power thousands of homes and businesses for a reduced cost, scientists have said.
Researchers at the University of Edinburgh have been trialling a device, which has been designed to be incorporated into existing ocean energy systems.
A series of small-scale experiments in a simulator show that a single full-sized device could generate the equivalent of 500 kilowatts of electricity - enough to power 100 homes.
"Wave energy is a potentially valuable resource around Scotland's coastline," said David Ingram, a professor at the University of Edinburgh.
The researchers believe that tidal power could deliver clean and abundant energy in the future, unlike fossil fuels which emit damaging levels of carbon dioxide and wind and solar power, which can be inconsistent.
