The continuing saga of the micro wind turbine in south London (NCE 15 February) brought to mind the engineer's adage: 'If it looks wrong, it probably is wrong.' A wind turbine on a big tent pole surrounded by trees and buildings does look very wrong.
I have worked on dozens of commercial wind farms.
For a typical smallish project, backers won't put up capital costs of say £20M without a year's worth of site wind speed data, measured at up to 80m, plus correlation, analysis and energy predictions, which will cost perhaps £30,000.
The Proven Energy wind turbines mentioned in the article have been successfully used worldwide for years. I welcome the new 'domestic' B&Q models, but I wouldn't install one on my house unless I wanted to make a green statement and lived in a windy location.
Before I made such a move I would invest in energy efficiency measures and solar (thermal) panels.
Microgeneration has a role to play in the energy mix but it will remain expensive compared with large-scale renewable energy.
