The era of cheap fuel is over. Whatever the results of the UK government’s current energy review, it looks like we’re all going to have to learn to live with high energy costs for the foreseeable future. Improved energy efficiency is the best way to mitigate rising prices, but it can be difficult to know where to start. Find out here how to optimise the efficiency of your steam boilers with instrumentation.

Motors account for two-thirds of the electricity used in industry – there are 10 million of them in the UK alone. Every percentage point that efficiency can be improved means significant savings. High quality motors are made of better materials and have lower losses than lower quality ones.

Using variable speed drives whenever there is a need to reduce motor speed can save as much as 60% of the energy in, for instance, a pumping application. Applied to a 90 kW motor in continuous duty, this could mean £23,000 per year in saved energy.

A modest speed reduction can give significant savings. Even if the speed is just a little too high, this can mean much higher energy consumption. A fan (or a centrifugal pump) running at half speed consumes only one-eighth of the energy compared to one running at full speed. Click here to watch our online demo.]

Climate change is affecting us all. Already, four of the five warmest years in England during the 340-year record have occurred in the last decade. But we could see a much greater rise over the course of the next century unless urgent action is taken to reduce greenhouse gas emissions significantly. There is growing scientific consensus that climate change is caused by our emissions of greenhouse gases.

You can save over £1,800 on the life cycle cost of a single 11 kW motor, simply by choosing high efficiency over standard efficiency. Multiply this with the number of motors on your site and you will see that this is an area where serious money can be saved.
