A tussle between Idaho and the feds exemplifies the flood of petitions that QFs have filed during the past several years, asking FERC to enforce or confirm their PURPA-guaranteed rights.
Stabilizing California's Demand
The real reasons behind the state’s energy savings.
of, it is not nearly enough to meet our AB 32 goals. To address this emissions reduction challenge for electricity, we will need to bend this curve downward, because, among other reasons, the population of California continues to grow rapidly, causing overall electricity use in the state to continue to rise by between one and two percent every year.” (emphasis added) p.7.

5. Figure 2 reflects total per capita consumption, which includes, or has embedded in it, economic structural changes over time. To isolate this effect on per capita consumption from EE savings, in our statistical analysis to the extent data was available, we utilized residential per capita consumption and residential savings.

7. It is important to note that a relatively stable pattern of per capita electricity consumption in this case translates into a moderate but still exponential growth in total residential electricity consumption of an average 2.1 percent per year between 1985 and 2007 (residential account data for PG&E, SCE, and SDGE supplied by the CEC). Such observed growth, though it may be slower than in the majority of other states, is nevertheless antithetical to the state’s global warming goals.

A cooling degree day (CDD) indicates how heavy the air conditioning needs are under certain weather conditions. One CDD is accumulated for each degree the average temperature for a day is over 65 degrees F (see http://www.energy.ca.gov/glossary/glossary-c.html and http://www.weather2000.com/dd_glossary.html ). A simple linear regression of California per capita consumption of residential electricity against the number of CDDs for the years 1970-2005 showed that the CDD variable “explained” almost 15 percent of the variability in the per capita consumption variable.
