Over half of electricity now from 'green sources'
Wandsworth Council says that it has achieved its target for cutting carbon dioxide emission three years ahead of schedule.
The original aim had been to reduce emissions by 20 per cent over a 20-year period to 2010. This was boosted in 2005 to 25 per cent. The target was reached earlier this year with the latest figures showing a 25.8 per cent fall.
The reduction is equivalent to more than 11,000 tonnes of carbon dioxide or 3,200 family homes.
Much of the success is down to increased use of 'green' low carbon energy as well as reduced consumption. The council purchases 56 per cent of its electricity supply from green sources. The council is also using 20 per cent less water than three years ago. This is mainly the result of the new Battersea Park borehole which supplies the fountains.
A new computerised energy management system has cut energy usage by 23 per cent at five estate boiler houses. The controls ensure boilers operate at maximum efficiency with temperature controls linked automatically to weather conditions.
Combined energy savings since 2006 are cutting around £700,000 a year off the council's £6 million energy bill.
A £400,000 loan fund was created with matching support from the Carbon Trust. Projects are targeted to achieve a five-year return on investment and reduce one tonne of carbon emissions for every £100 spent. Savings from new projects are ploughed back into the fund which helps to support new initiatives. In the last year the council has spent £110,000 on new projects which will produce annual energy savings of 178 tonnes. Measures include cavity wall insulation for buildings and automatic lighting controls.
On housing estates the council is trialling solar water heating systems and photovoltaic panels to generate electricity. Voltage reduction devices have been fitted successfully at Putney library and will now be extended to include Balham and Tooting leisure centres.
Executive member for environment and leisure Malcolm Grimston said, "Within the town hall we are training staff to develop their awareness of new approaches to energy reduction both at work and at home. Creating a network of energy champions is the key to achieving continued reductions in our use of energy, carbon dioxide and water."
From 2010 councils will be required to purchase carbon allowances to cover its emissions. This will provide further incentives for reducing energy consumption.
