The largest power potential from wind in the spring, summer, and fall typically occurs in the evening and early morning when the regional load demand is not at its peak. Although the wind resource peak power potential does not coincide with the peak of the regional load demand, wind can still be used to meet some of the Region’s energy needs. Figure 4.1 illustrates the seasonal hourly wind potential.

While California’s per capita electricity consumption has held steady for three decades, per capita gross state product (GSP) has doubled.  This shows that California’s economy has become less reliant on energy to produce goods and services

The Rosenfeld Effect

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.

California is the eighth largest economy in the world, according to the state's Legislative Analyst's Office. To meet the needs of its growing population, California's economy depends upon affordable, reliable, and environmentally sound supplies of electricity, natural gas, and transportation fuels.

The staggering fact is the one highlighted: more than a fifth of all of the state’s electricity [used on water things!] goes to move water around. One-fifth!

Image: 

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

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.

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.
