  2. ``I think you should be more explicit here in step two...''

  3. Useful Conversion Factors1 • 1 CCF = 100 CUBIC FEET • 1 MCF = 1,000 CUBIC FEET = 1MMBTU • 1MBTU = 1,000 BTU • 1MMBTU = 1,000,000 (106) BTU • 1 THERM = 100,000 (105) BTU = APPROX. 100 CUBIC FEET OF NATURAL GAS = 29.3 kWh • 1 kWh = 3412 BTU • 1SCF = 1,000 BTU* *P2 Program GHG calculator uses 1,027 BTU • 1 metric ton (tonne) = 1.1 short ton 1Association of Energy Engineers Certified Energy Manager Manual

  4. EPA’s Pollution Prevention GHG Calculator • Quantifies reductions based on conversion factors • Electricity conservation • Green energy sources • Fuel use and substitution of greener fuels • Greening chemistry (reduced emission of GHG directly • Materials management (TBD) • Water conservation

  5. EPA Pollution Prevention Program’s GHG Calculator (cont) • Converts standard metrics into metric tons of carbon dioxide equivalent (MTCO2e) using standard national conversion factors • Aggregates by category and by total project (does not carry project titles forward) • National conversion factor 7.21 x 10-4 MTCO2e/kWh; can also use state-specific emission factors • Iowa: MRO, 9.54 x 10-4 MTCO2e/kWh • Kansas: SPP, 7.1 x 10-4 MTCO2e/kWh • Missouri: RFC, 8.58 x 10-4 MTCO2e/kWh (Why? Should be SPP/SERC) • Nebraska: MRO, 9.54 x 10-4 MTCO2e/kWh (also has WECC) • GHG Conversion Tool_April 7 2010.xls

  6. Example 1 • Intern from Iowa makes the following recommendations • In this example, and all subsequent examples, what are the total reductions in GHG (in metric tons CO2 equivalents [MTCO2e])?

  7. Example 1 • 95.157 MTCO2e • 71.92 MTCO2e • Either A or B • None of the above • Can’t tell from the information given

  8. Example 2 • An intern at a facility in Knoxville, Iowa recommended a waste heat recovery project, reducing 264,310 therms of natural gas.

  9. Example 2 • 14.440 MTCO2e • 1,406.023 MTCO2e • Either A or B • None of the above • Can’t tell from the information given

  10. Example 3 • Intern at Minnesota facility works on SF6 replacement project that saves the facility $200,000 per year.

  11. Example 3 • 2,168,208 MTCO2e • 1,084.104 MTCO2e • Either A or B • None of the above • Can’t tell from the information given

  12. Example 4 • Intern at Minnesota facility recommends replacing 1,000 pounds of SF6 with 1,000 pounds of N2O/CO2 mix (50/50).

  13. Example 4 • -10,770.505 MTCO2e • 10,770.405 MTCO2e • Either A or B • None of the above • Can’t tell from the information given

  14. Example 5 • Intern at Kansas facility works on a project that injects propane into diesel engines. Using 3,993 gallons of propane, the company saves 4,616 gallons of diesel. The carbon content of propane is 5.74 kg CO2/gallon1. The Climate Registry General Reporting Protocol, Page 90, http://www.theclimateregistry.org/downloads/GRP.pdf

  15. Example 5 • 24.199 MTCO2e • 66.519 MTCO2e • Either A or B • None of the above • Can’t tell from the information given

  16. Example 6 • Intern at a nuclear power plant in Kansas conducts an HVAC replacement project that conserves 215,280 kWh of electricity and replaces 768 pounds of HCFC-22 with R-410a.

  17. Example 6 • 152.916 MTCO2e • 783.456 MTCO2e • 785.827 MTCO2e • None of the above • Can’t tell from the information given
