Production Output
Enter both consumption and cost for at least one energy source to calculate.
Common Quick Wins
LED lighting upgrade
1-2 year paybackReplace 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 paybackMotors 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 paybackImprove insulation on buildings, pipes, and storage. Reduces heating and cooling loads year-round.
15-25% heating reduction
Compressed air leak repair
Often <1 year paybackCompressed 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 paybackOn-site solar generation reduces grid dependence and locks in long-term electricity costs. Grants often available.
Offset 30-50% of electricity
