Business and Energy - 3 Drivers
Rising energy costs World oil, gas, coal prices all rising Prices will remain high and volatile for foreseeable future
High demand - China, supply side instabilities, shortages of capacity Increasing reliance on imports – links gas prices more closely to oil No return to historic norms
Environmental compliance Increasing raft of rules and regulations relating to emissions IPPC provides legal framework to drive improvement
Carbon management Slow start but growing inducements to reduce carbon emissions Climate Change Levy (carbon tax) moving to EU ETS II
And …. Rising energy costs

Just motors …
Electric motors use 65% of electricity in industrial facilities Focus on the larger motors on the site
Eliminate / reduce idle (no load) time
Challenge sizing of motor (starting load / running load)
Challenge duty of motor (pumps, agitators, grinding, fans, compressors)
Consider use of variable speed drives (pumps & fans in particular)
