In the poem “Mending Wall,” Robert Frost asserted that “good fences make good neighbors.”  World history is replete with foreign policy built around physical walls, from Emperor Hadrian, to the Great Wall of China, to the Berlin Wall, the wall between Palestine and Israeli, to the U.S.-Mexico border.  Containment and isolation have often been the cornerstones of policy. ...

In 2007, geothermal energy in our state produced 13,000 gigawatt-hours of electricity. Combined with another 440 GWh of imported geothermal electricity, then geothermal energy produced 4.5 percent of the state's total system power. A total of 43 operating geothermal power plants with an installed capacity of nearly 1,800 megawatts are in California, about two-thirds of the total United States' geothermal generation. ...

The Rosenfeld Effect

Image: 

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.Though electricity demand nationwide has risen sharply in recent years, California's per capita electricity use has remained relatively flat since 1973 because of the state's strict energy-efficiency regulations.

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

Source: 

http://www.eia.gov/todayinenergy/detail.cfm?id=10531

Image: 

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. ...
