Among several energy saving initiatives, Variable Speed Drives can help manufacturing to achieve 60% of immediate energy saving, reports Envido.

Recently there has been an influx of regulations applied to manufacturing industry that has a major impact on energy use. Among them the CRC Energy Efficiency Scheme will apply mandatory emissions trading to cut carbon emissions from large non-intensive users in the private and public sectors. The CRC Energy Efficiency Scheme has the potential to reduce carbon emissions in the UK by up to 11.6m tonnes per year by 2020.

To reach the CRC Energy Efficiency Scheme levels there are several energy saving initiatives that can be introduced such as; insulating buildings to a high standard, fitting low-energy lighting controlling building temperature to an agreed standard and using Voltage Optimisation technology. Other more detailed measures include compressor upgrades, warm-up cycle timers and smart metering.
Along with these technologies, one of the biggest impact on energy saving can come from applying Variable Speed Drives to many of the electric motors used throughout industry and commerce. In manufacturing nearly 60% of immediate energy saving can be achieved by looking at more efficient drive systems after applying Variable Speed Drives.

Significant energy savings possible from using Variable Speed Drives
It is still a little known fact that 65% of all energy used in industry is consumed by the electric motor. And yet only about 5% of this installed based has a variable speed drive to control the motor speed depending on the demand. With some 10m motors installed throughout the UK alone, the potential to reduce energy use is huge.

Currently, many organisations are busy measuring and recording their actual energy consumption and carbon emission usage. This is a good start, but ultimately the only way to look good in the Government’s league table will be to cut carbon emissions.

The Carbon Trust encourages industry through interest-free loans from £3,000 to £100,000 to invest in new technology like Variable Speed Drives and Energy Efficient Electric Motors.
