What should I do concerning energy?

The Issue Wiltshire College
The predominant energy sources in the UK are based on fossil fuels, the use of which contributes to climate change. Wiltshire College contributes over 1.3 million tonnes of carbon dioxide equivalent to the atmosphere every year through its electricity use alone. The College is currently calculating its carbon footprint, but information about each site's energy efficiency is displayed at each College Reception area. We have a target to reduce energy use by 4% during 2009/10, and 15% over five years.

Energy efficiency measures

Ways You Can Help:


  • Switch off lights that are not needed.
  • Make maximum use of daylight (as light bulbs generate approximately 10% light and 90% heat. this is particularly relevant during hot summer months when you need to keep heat gain to a minimum).
  • Reduce decorative lighting.
  • Ensure you switch off lights as you leave your work area, rather than waiting for site officers to do this 3-4 hours after you have left!
  • Do not switch on all lights when only a few are needed.
  • Use local desk lights if a few people are in the building.
  • Fit low energy lights/bulbs that last eight times longer than conventional light fittings and use only one quarter of the electricity.
  • Turn fluorescent lights off – it's a myth that leaving fluorescent lights on uses less energy than turning them off and on throughout the day.


  • Do not switch on computers, printers and other equipment until they are needed (a 'just in time' system is the way forward). Some machines take less than 2 minutes to reach the 'login' stage, so this new approach should not be too inconvenient to both staff or students.
  • Switch off your computer when going off to teach or not using it for a significant time (more than 30 minutes) and at the end of your working day.
  • Switch off all classroom/LRC machines at the end of each teaching session.
  • Follow the computer close down procedure by shutting down via the Welcome Page, and manually switching off the monitor (monitor light should be off completely, not in standby mode).
  • Do not turn off at the mains switch. Leaving equipment in standby mode uses approximately 80% of the power it would have done if the appliance had been fully left on. Turning monitors off completely also extends the life expectancy of the appliance - an added bonus. It is estimated that up to 15% of domestic electricity worldwide is wasted by people using standby unnecessarily!
  • Although each piece of equipment may only use a small amount of energy, it all adds up. Energy used is given off as heat, and this can make the working environment uncomfortable. This is most noticeable in rooms with a large number of computers. Adopting the 'just in time' approach to computer usage will help reduce heat gain problems, and improve the working environment for both staff and students.


  • Only boil enough water for the drink you are making – don't fill the kettle
  • Use central hot water dispensers instead of kettles where they are available


  • Close windows and doors when rooms are being left empty.
  • Do not use fan heaters or similar devices unless you really need to; in which case notify your site officer so that she or he can determine whether more efficient methods should be introduced.
