Rosenfeld founded a group that became the lab's Center for Building Science. Research on the miniaturization of electronic ballasts in fluorescent lamps led to the development of the first compact fluorescent lamps. The center also developed low-emissivity windows as well as computer programs for the energy analysis and design of buildings.

CA electricity consumption by sector

Submitted by eortiz5000 on Wed, 05/29/2013 - 10:23

All major sectors of California's economy show modest, steady growth over the last decade. Between 1995 and 2000, the state's electricity consumption overall, as well as its residential sector, grew 2.5 percent per year. This growth rate is not unusual for the state when compared to the historic record, and is moderate when viewed in the context of the growing population and economy.

Extended nuclear generation outage increases Southern CA's energy prices relative to Northern CA

Historically, wholesale power prices for Northern and Southern California tracked closely with one another, indicating minimal market differences between the two areas. However, after the shutdown of SONGS in early 2012, the relatively inexpensive nuclear generation produced by SONGS had to be replaced with power from more expensive sources. Consequently, since April 2012 Southern California power prices have persistently exceeded Northern California prices, with the spread averaging $4.15/MWh, or 12% of the Northern California price.

The efficiency of energy use in growing the U.S. economy has made dramatic improvements over the past 60 years.  Before the mid-1980s electrical energy usage grew faster than GDP growth but since then the relationship has reversed.  Projections by the U.S. EIA (U.S.

The urban island effect

Submitted by eortiz5000 on Wed, 05/29/2013 - 09:23

This hypothetical graph shows how daytime and nighttime temperature vary in the vicinity of a large city. Notice how daytime temperature is higher over heat-reflecting buildings and lower over a water body. The urban heat island effect causes cities to run warmer than surrounding rural areas, especially at night. Development produces heat islands by replacing vegetation, particularly forests, with pavement and other urban infrastructure.

CA energy demand forecast

Submitted by eortiz5000 on Wed, 05/29/2013 - 09:07
Unlike consumption, peak over all sectors in 2010 was very close to the CED 2009 statewide projection; although 2010 was a mild weather year overall, a heat storm event(extended heat wave) in September 2010 yielded a relatively high peak. The figure also indicates noncoincident weather‐normalized peak demand in 2011, higherthan the actualtotal since this was a relatively cool year. Growth rates in the forecast period are calculated relative to this weather‐normalized total, which is significantly lowerthan the peakpredicted in CED 2009.

Total vehicle miles traveled (VMt) and VMt per capita declined slightly from 2007 to 2010 (-1% and -3.2%, respectively), though both increased compared to 2009 (Figure 34). 
Greenhouse gas emissions from transportation dropped by a much wider margin, with a ten percent drop in per capita emissions between 2007 and 2010, and a continued 
improvement since 2009 in both overall transportation emissions (-0.3%) and per capita transportation emissions (-1.1%).

Access to high-speed connections such as DSL and cable modems, represent a new dimension of digital divide. With the rapidity of technological change, very many people who thought yesterday have sufficient technological skills and now find themselves sidelined and  destabilized.

About a quarter of whites and a third of Asians have of broadband access at home, unlike the Mexicans who have the lowest rate.

Only one of out ten Mexican-Americans has a hi-speed connection at home.
