Re: P2 Impact of Bulbs

Question poses:
In the Emissions Factors for Coal Fired Power Plants, does the reference to "worst case" emissions factor mean the numbers are as conservative as possible or as generous as possible?  Coal is a tough one because of the wide range, so I'm just curious to know how you decided to handle it.
We based the calculation on the least positive benefit. So actually in many cases the implementation of the P2 recommendation could have a greater benefit than our calculator shows.

Sue and other fellow P2Techers,


Thanks for relaying the P2 and lighting information.


For those of you interested in determining emissions avoided from electricity savings (whether from efficient lighting or other end use measures) and alternate supply( renewable generation and CHP/co-gen), there are some other tools and data available.


EPA Power Profiler http://www.epa.gov/cleanenergy/powerprofiler.htm provides average NOx, SO2, and CO2 emissions per MWh on a regional basis.


EPA eGRID http://www.epa.gov/cleanenergy/egrid/index.htm ?eGRID is a database that provides information on the air quality attributes of almost all the electric power generated in the United States. eGRID provides you with many search options, including information for individual power plants, generating companies, states, and regions of the power grid.?


DOE Energy Information Administration http://www.eia.doe.gov/cneaf/electricity/st_profiles/e_profiles_sum.html provides state summary reports, which include NOx, SO2, and CO2 emissions from electricity generation. (Click on state name for state summary report.)


Please be aware that your local and regional generation mix and, thus, emissions per MWh vary based on demand, generation asset availability, and other factors affecting utility power dispatch.

Apology for cross posting and please forward to appropriate regional P2 listserves.

The Small Business Pollution Prevention Center has recently posted the Impact of Pollution Prevention tools at http://www.iwrc.org/SBPPC/index.htm


I hope that the data presented in this project is useful to your clients and in assisting with more meaningful measurements as to the actual impact of P2 by quantifying the toxins reduced when P2 suggestions are implemented.

Pollution Prevention Impact of Fluorescent Bulbs

Incandescent bulbs and fluorescent tubes are the most common lighting used in businesses today. Switching to either compact fluorescent or low-mercury fluorescent bulbs can have a major impact on energy cost savings, as well as lessen your contribution to energy production-related pollution, including global warming.
