Lower your impact

Conserving energy

Using less costs less

If you reduce your energy consumption you can save money and reduce greenhouse gases caused by burning fossil fuels.

Improvements can be made...

In the workplace

  • Turn off all lights and equipment when they do not need to be operating.
  • Use energy efficient office equipment and power saving functions where they will be most effective.
  • Use the most efficient motors, make sure equipment is the right size for the job, that is, not too big.
  • Use the most efficient lights – triphosphor tubes are cheaper to run than fluorescent lights.
  • Replace incandescent globes with fluorescent tubes to save power as well as reduce air conditioning loads and reduce labour needed to change globes.
  • Install skylights in the roof or walls to reduce the need for artificial lighting.
  • Minimise expenditure on space heating. At 20°C, a 1°C increase can cost about 20 per cent more.
  • Insulate rooms to minimise energy waste.
  • Fit self closing doors to reduce heat (or cold) loss from draughts.
  • Consider installing a co-generation plant to reduce energy costs and increase energy efficiency.
  • Minimise the use of hot water as it costs much more than cold water.

In the process

  • Improve insulation of all hot process items and steam lines to minimise simple heat loss.
  • Remove frost on refrigerated coolant lines through better insulation. This will keep the ice where you need it and where it can add value to your business.
  • Avoid steam leaks. A 1kg/min steam leak costs about $1/hour and $2/hour in an air-conditioned space.
  • Find ways to transfer heat from hot process streams into cold streams.
  • Ensure your boiler is tuned properly and that blowdown losses are minimised. Improved feedwater quality (for example rainwater) may help reduce blowdown losses.
  • Require suppliers to quote the energy consumption and costs of a new piece of equipment.

When choosing energy sources

  • Investigate alternative energy sources such as solar hot water, waste, bio-ethanol and wind energy.
  • Use a clean fuel such as LPG or methanol.
  • Use fuels with the least greenhouse impact.

A list of fuels that have the greenhouse gas impacts. Ther are sorted from least to most impact in the following order; Methane, LPG, Oil, Diesel, Black Coal, Brown Coal
