Energy Efficiency ROI Calculator

See how much energy costs you per unit of output — and what efficiency improvements could save.

Your Current Energy Profile

Electricity

Fuel (diesel/petrol)

Natural Gas

Production Output

Enter both consumption and cost for at least one energy source to calculate.

Common Quick Wins

LED lighting upgrade

1-2 year payback

Replace fluorescent and halogen lighting with LED equivalents. Often the simplest and fastest efficiency win.

60% reduction in lighting energy

Variable speed drives on pumps/fans

2-3 year payback

Motors running at full speed when partial speed would do waste significant energy. VSDs match output to demand.

20-40% reduction in motor energy

Insulation improvements

3-5 year payback

Improve insulation on buildings, pipes, and storage. Reduces heating and cooling loads year-round.

15-25% heating reduction

Compressed air leak repair

Often <1 year payback

Compressed air systems commonly leak 20-30% of output. An ultrasonic leak survey and repair programme pays for itself fast.

20-30% reduction in compressor energy

Solar PV installation

5-8 year payback

On-site solar generation reduces grid dependence and locks in long-term electricity costs. Grants often available.

Offset 30-50% of electricity
