2. © ABB Engineering Services - 2 Workshop Session - Energy Introductions The Drivers (reminder) How can … Now let’s talk about your experiences … Practical Opportunities & Real Issues … how they were realised and how they were overcome

3. © ABB Engineering Services - 3 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
