be sustainable where you can asked: Is it only small wind turbines that can practically be purchased in the UK and can be mounted on roofs? I would like to investigate the possibility of a very large company, with many buildings and very high energy bills, harnessing wind power. There is not enough land space for a free standing large turbine but plenty of roof space (I will also look into PV panels but would like to understand wind further first). It is quite an Urban are, but the company has one very tall building)
Thanks for any advice…..
