Watergate Bay Hotel has chosen south west green electricity company, Good Energy, to supply its electricity.
Good Energy, which owns the Delabole wind farm on the north Cornwall coast, sources around a quarter of its electricity from the south west.
For Watergate Bay Hotel, the move is the latest step in its drive to invest in sustainable technologies and limit its impact on the environment.
Commercial director, Chris Hugo, said: “Good Energy guarantees to match all the electricity we use with electricity sourced purely from renewables right here in the UK, and that’s very important to us. The fact that a lot of its power is sourced from the south west is a bonus.”
