Hi Boorach,
welcome to the forums.
Regarding the wind turbine, the installation costs will vary depending on location and the size and type of system. However the basic components are usually the same:
turbine, mast, inverters, battery storage (if required) and installation
I have found a guide price a system in the region of 2.5kW would cost roughly £11,000 installed.
For a more detailed breakdown, you could try contacting
www.provenenergy.co.uk in East Kilbride
For ground source heat pumps, a typical 8 - 12kW system costs £6,000 - £12,000 (not including the price of distribution system).
For a more detailed estimate of the likely costs, you could try contacting EarthWise (
http://www.earthwisescotland.co.uk/) who are based in Aberdeen and specialise in ground source heat pumps.
I'm sure others would be interested to find out the sort of quotes that you get back - perhaps you could post a follow up.
