Monmouthshire County Borough Council

The "Quiet Revolution" vertical axis wind turbine on site was chosen for asthetic reasons following consultation with the local residents who indicated that horizontal axis wind turbines were considered less attractive.

A vertical axis wind turbine of this size can generate up to 7,500 kWhrs of electricity per year, dependent on availability of wind. As these turbines do not need to turn into the wind to provide optimum performance they are particularly suitable for sites with turbulent conditions, they are also less noisy, however they are not quite as efficient as horizontal axis turbines

The wind turbine produces approximately twice the schools electricity requirement. Surplus energy is exported to the grid via an export/import meter.

The school uses approximately 40,000kWh per year and average wind speeds of 7m/s the turbine has been calculated to produce 100,000 kWh a year. Calculations reveal that 56.8 tonnes of CO2 will be saved per year.

St Columb Minor School,
Cornwall County Council

In 2008 a 6kW wind turbine was commissioned at the school. The solar PV and wind turbine combined generates about 23,000 kWh/year, saving about 11 tonnes of CO2 per year in total. Electricity consumption has fallen by around 37% as a result of the turbine, solar PV and behavioural measures.

Parents and the community were consulted regularly during planning for the turbine and no objections were raised. There is a display meter in the school foyer showing the energy generated and CO2 saved together with a monitor showing the schools electricity consumption.

Ladygrove Primary School,
Shropshire County Council

The school has a 2.5kW wind turbine with a mast height of 6.5m. Annual electricity output is in excess of 6,500kWh. The electricity generated contributes approximately 15% of the total schools requirements significantly decreasing electricity costs by approximately £400 per year. Around 3.5 tonnes CO2 emissions will be saved each year.

The turbines output is being recorded using computer software and is compared with the wind speed recorded on the school's weather station.  The turbine acts as an educational resource and sustainability focus for the whole community.
