Cette association a pour objet de :
  • Favoriser les démarches d'auto construction d’éolien individuel type Hugh Piggott
  • Construire des turbines en répondant à un besoin d’électricité identifié ;
  • Donner des notions théoriques de base associées au fonctionnement d’une éolienne ;
  • Promouvoir la réduction des gaspillages énergétiques, l’amélioration de l’efficacité énergétique et l’utilisation des énergies renouvelables afin de réduire les inégalités, de partager plus équitablement les ressources naturelles et de mieux préserver l’environnement ;
Pour la réalisation de son objet, l’association se donne comme moyens d’action, de façon non exclusive ni limitative, la recherche, la démonstration, la formation, la production et la diffusion d’information, l’organisation d’échanges de toute nature, la représentation dans différentes instances, et d’une manière générale l’engagement de toutes actions et projets permettant de promouvoir et réaliser ces différents objectifs.

"I recently purchased your June 2005 edition of  "How to build a wind turbine". It arrived just last week and I read through it from cover to cover that very day. You are to be congratulated for the amount of detail, hints and information this manual contains. I can certainly understand the amount of work (and tears), to put this sort of information into a manual. One of the best 'how to' books I've ever read (and I have a few). "

"Choosing Windpower" from CAT publications (October 2006)
(replaces my older booklet "It's a Breeze" from CAT)
choosing windpower"Logical and readable style that cuts straight through the jargon" - Windirections

Description

Choosing Windpower is the definitive guide for any ecologically-minded person who wants to generate electricity off the grid using windpower. As a variable and at present expensive option of electricity generation for a household, the book deals with a 'stand-alone system' for those in remote areas who wish to slash the environmental and monetary costs incurred by diesel generation. With sections on assessing your needs, the electrical ins and outs of wind turbines, where to site the turbines and finally how to go about setting up a turbine, the book is a valuable reference point for all those with no access to mains electricity.
Learn how to assess your power needs and find out whether wind power is right for you.

Choosing Windpower is the brand new edition of 'It's a Breeze', brought up to date with full revisions

In their pilotproject in M'muock, Cameroon they train 10 local craftsmen to build small scale wind- and waterturbines from mainly locally available material for energy production.

Rooftop wind turbine madness in the UK.

(Picture from Paul Gipe's site.)

The Warwick Urban Wind Trial project has engaged in depth with the new market for  urban, building mounted wind turbines at a critical time in market development.    By taking the customer perspective and combining technical monitoring with social  research into the impact of installations on public perceptions of energy efficiency  and wind, the project is providing the most thorough and complete assessment to  date of the efficacy of urban wind systems in supporting UK energy and  environmental policies.  



A new Carbon Trust study into the potential of small-scale wind energy has found that small wind turbines could provide up to 1.5 Terawatt Hours (TWh) per year of electricity (0.4% of total UK electricity consumption) and 0.6 million tonnes of carbon dioxide (MtCO2) emission savings.  This is based on 10% of households installing turbines at costs competitive with grid electricity, which is currently around 12p per kWh.

The study also indicates that for the UK as a whole, the majority of electricity and carbon savings are available from small turbines in rural areas - four times as much as urban areas irrespective of costs, and considerably more given economic drivers. This is mainly due to wind speeds generally being higher in rural areas.  Turbines in some rural locations could provide cheaper electricity than the grid, but it appears that in many urban situations, roof-mounted turbines may not pay back their embedded carbon emissions.

The report published today marks the culmination of 18 months research by the Met Office and Entec, and is partly intended for government policy makers. It makes important recommendations to improve existing policy measures, including that:

• A criterion should be used in any new grant schemes to measure likely carbon savings.  This is to help ensure grants are awarded to installations which save reasonable amounts of carbon; and
• Higher height limits for stand-alone turbines should be allowed under permitted development rights.  This is to help maximise the overall carbon savings of small-scale wind energy, given the sensitivity of electricity generation to height.


Rooftop windspeed measurements

in the city 

(updated with response from RD Swift turbines, and my email to BWEA)
Mostly now when I see these swift turbines they are under repair for some reason.  It looks awful.

The new certification body BRE have come out with new guidelines for estimating windspeed on urban sites that you can download.

These rules of thumb (see appendix suggest that the windspeed at rooftop level is approximately 50% of what you would expect from using the DTI (NOABL) data set that everyone relies on.  That means 1/8 of the energy production.

Further evidence from the Warwick Wind Trials shows that most of the new generation of rooftop turbines also fail to meet their claimed output, often only achieving 30% or less.  In many cases the inverter's standby power consumption exceeds any power generated on urban sites.
