“This figure shows carbon dioxide emissions from 1990 to 2011 for different regions of the world. These totals do not include emissions or sinks related to land-use change or forestry. Inclusion of land-use change and forestry would increase the apparent emissions from some regions while decreasing the emissions from others.” – United States Environmental Protection Agency

“This figure shows concentrations of carbon dioxide in the atmosphere from hundreds of thousands of years ago through 2013, measured in parts per million (ppm). The data come from a variety of historical ice core studies and recent air monitoring sites around the world. Each line represents a different data source.” - United States Environmental Protection Agency

“This figure shows how annual average temperatures worldwide have changed since 1901. Surface data come from a combined set of land-based weather stations and sea surface temperature measurements. Satellite measurements cover the lower troposphere, which is the lowest level of the Earth’s atmosphere. “UAH” and “RSS” represent two different methods of analyzing the original satellite measurements. This graph uses the 1901–2000 average as a baseline for depicting change.

Seasonal Hourly Wind Output in San Diego

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

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.
