Global Carbon Dioxide Emissions by Region, 1990-2011

Submitted by c.bernhardt.14 on Thu, 06/05/2014 - 14:16

“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.

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.

Electricity use and GDP

Submitted by eortiz5000 on Wed, 05/29/2013 - 11:15

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
