5、er for greater efficiency,Fuel Switching Example: Replace coal boilers with gas-fired units, use biofuels instead of diesel. (* NOT nuclear!),Energy Efficiency (EE) projects usually reduce the energy demand per unit of output and thus offer other benefits of cost saving and production efficiency EE
6、projects for CDM can involve either upgraded or new equipment CDM Transaction costs are high so often need to group many projects under one CDM project to make viable EE projects are difficult to baseline, monitor + verify, and special guidelines have been produced to assist calculation Must first e
7、stablish Emissions Baseline the greenhouse emissions which would have occurred in business as usual, ie: if the CDM project was not done. Small projects (up to 15MW generation capacity or 15GWh/yr of equivalent energy savings) have special simplified rules and calculations,Energy Efficiency CDM Cons
