Cheverton Down Wind Turbines: Cornwall Light and Power Interview, Part Three (Podcast)
Wednesday, 25th February, 2009 at 11:00 am, Isle of Wight
Environment, Green Issues, South Wight, podcast
This is the next edition of the Cheverton Down interview with Cornwall Light and Power, following on from the first and second parts.
Rather than write up with whole thing, here’s a flavour of what’s spoken about …
What’s the efficiency of wind turbines like?
We learn what a nacelle is and its relationship to the generation of electricity. How the electricity is transferred on-site.
The relationship between the sweep area of the blades and the electricity that is generated.
How efficient wind turbines are over their lifetime?
They haven’t been taking actual wind readings at Cheverton Down, relying on the NOABL readings.
Wind turbines can start generating electricity from winds of 6 m/s
The cut-in speed – when the blades start moving – is 4 m/s.
They reach full capacity at 15 m/s and will continue until 25 m/s, at which point they cut out.
