Environmental Sustainability – Energy Saving Checklist

Energy Saving Checklist

Welcome to the The Manufacturer‘s Environmental Sustainability Resources Area – Energy Saving Checklist.

The Carbon Trust estimates that you could cut the energy bills in your manufacturing operations by as much as 20% just by implementing simple, inexpensive energy efficiency measures such as using variable-speed drives, fixing leaks in your compressed air systems, and cleaning your refrigeration condensers.

Here are some energy efficiency tips to get you started.

Lights and Electronics

Tip: Install movement sensor lights to automate this process.

Tip: Check for computers/lighting left on when not in use.

Tip: Replacing high wattage filament lamps or tungsten halogen lamps with compact fluorescent lamps or metal halide lamps will give energy savings of 65-75%.

Tip: Ensure window blinds are open in daylight hours and make use of skylights.

Tip: Fitting a daylight sensor control can assist with this.


Tip: Payback periods can be as low as 12 months.


Tip: Reduce a motor’s speed by 20% with a variable speed drive and its energy consumption could drop by as much as 50%.

Tip: These might qualify for tax relief through the Enhanced Capital Allowance Scheme and could also help you to reduce your energy consumption.

Tip: Lubricate them where appropriate, and check belt tightness and alignment.

Compressed Air

Tip: A 1-bar reduction could save about 7% of the energy required for compression.

Tip: A compressor installation that is on when there is no demand will consume 20-70% of its full load power.

Tip: Compressed air leaking through a single 3mm hole could cost you nearly £700 per year in energy costs.


Tip: A faulty one could increase the refrigeration unit’s power consumption by as much as 11%.

Tip: Dirty condensers can increase costs by around 26%.


Tip: Offices should be set to 21°C in winter and 24°C in summer, and workshops should be set to 16-19°C.
