We have two Evance R9000 5KW wind turbines installed in one of our fields: one turbine helps to power our farmhouse (Orcadian Wildlife's base); whilst the other powers our Peedie House self-catering cottage.  Both turbines are set to produce nearly 20,000 KW hours each of clean green energy of which we aim to export half to our energy supplier Good Energy (see www.goodenergy.co.uk).  The wind turbines were commissioned on 2 July 2011 and installed by Alternative Energy Contracting Ltd (see www.bae.uk.net).
 

Gerraquoy farmhouse (Orcadian Wildlife's base) is heated by a 9 KW ground source heat pump (type Dimplex SI 9ME) which provides central heating and hot water for our family and guests.  The ground source heat pump was installed in October 2010 by Steven R Paterson Ltd. of Orkney (see www.stevenpaterson.co.uk).
 

Gerraquoy farmhouse (Orcadian Wildlife's base)  has two solar panels mounted on its south-facing roof; and the Peedie House self-catering has one solar panel mounted on its south-facing roof; all of which help to heat the hot water required in these properties.  The Peedie House panel was installed in April 2007; the Gerraquoy farmhouse panels were installed in May 2010 (all installation done by ourselves).
