Above: Anasazi cliff dwellings demonstrate passive solar design techniques. Passive design is also noted in the architecture of early Mesopotania and the highly developed societies of early South America.
Above: Santa Rita Jail in Dublin, CA. This 1.18 megawatt PV system spans three (3) acres and supplies 30% of the jail electricity.

Above: The world’s largest solar power facility near Kramer Junction, CA. The facility covers more than 1000 acres with a capacity of 150 megawatts.
Above: The photons from the sun penetrate and randomly strike the
silicon atoms. The atom becomes ionized, passing energy to
the outer electron, thereby allowing the outer electron to break
free from the atom. An electric current is created.
Harnessing incoming solar radiation through the use of solar collectors to produce energy
Uses include water heating for use in the home and in swimming pools. As well as space heating in the home
Active solar System
Newenery.orgWhat is Active Solar
A collector field comprises many troughs in parallel rows aligned on a north-south axis. This configuration enables the single-axis troughs to track the sun from east to west during the day to ensure that the sun is continuously focused on the receiver pipes. Individual trough systems currently can generate about 80 megawatts of electricity, enough to power a city of 110,000 people. Of course, individual systems can be grouped to provide more power.
Often these systems are “hybridized” with fossil fuels to produce power 24 hours a day.
The first parabolic trough solar power plant became operational in 1984, and continues to provide power today.
Texas has more renewable energy potential than any other state due to its size and diverse climate. The main obstacle is developing technology that can tap non-polluting resource.
One of 11 programs within the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy.
Focus on developing solar energy technologies to power our world.
