RE: Converting energy conservation to environmental impacts



Judy,

The Energy Information Administration of DOE has state level data on power generation and emissions of NOx, SO2, and CO2.  So one can easily derive, based on an average state blend of power, NOx/kWh, SO2/kWh, and CO2/kWh.   (You'll also have to consider whether to count utility generation and emissions only or also non-utility generation in the blend.) A more precise approach would be to use your specific utility's blend of generation and its emissions. I'd imagine CT DEP would have data on emissions for generation in CT. 

Because CT's power generation is heavily nuclear and very little coal, the NOx, SO2, CO2 savings per kWh are probably not going to be as impressive as in some other states.  But depending on your application you may also be able to consider NOx reduction from reducing the use of on-site furnaces, boilers, or water heaters at the facility in question.

I hope this is useful.

	I have a client that is proposing to do an energy conservation project as a
	Supplemental Environmental Project, for our CTDEP.  What I am looking for, in
	order to support his proposal, is a way to show the impacts of kilowatt hours
	saved to environmental benefits, e.g., lbs. of C02 reduced, SO2 reduction,
	barrels of oil saved, etc.

	Can anyone guide me to such a place that we can use as a reference?  Appreciate
	any help you can give us.


	Thanks,
