Source of electricity is generally not specific plants but categories such as wind, solar, coal, nuclear, hydro, natural gas sources of electricity. Source certification can take the form of “green certificates” which would be an example of a source warrant. A buyer of electricity would want to know if ownership such certificates are conveyed by a product or are stripped off. A source warrant can make this clear. Otherwise a source warrant may be provided by operators of generators for example. I cannot find any use of “electricity content” but there may be a use. Edward G.

I was going to say drop the source warrant... My reasoning: what's delivered to the customer has contents; tracing to actual source is as we've seen usually disconnected by way of markets for "green certification". So the assertions about the product delivered seem to me to be more clearly the contents, rather than source. The alternate argument is that the source for your product reflects the contents, so they're related. That said, I agree that one needs to go, and I don't care very strongly which.

Cazalet'; [email protected] Cc: [email protected] Subject: [emix] Source and Content The current specification has both Source and Content Warrants. I have been unable to find any definition that distinguishes between these two, and on the CPUC site, they appear to be identical. Any suggestions? The choices are (1) Find a distinguishing definition (2) Delete one or the other. “The single biggest problem in communication is the illusion that it has taken place.” – George Bernard Shaw.
