FedEx’s New Solar System Is Enough To Power 370 homes
FedEx Express, a subsidiary of FedEx Corp, broke ground on its first - and largest - international solar energy facility on Monday. The facility near the Cologne, Germany airport will house over 16,000 square meters of solar panels.
The new solar panel installation is slated for completion by 2010; a 1.4-megawatt (MW) solar power system that will generate 1.3 GWhs of electricity/year. That is equivalent to the annual consumption of 370 homes!

Known for building homes across the world for those in need, Habitat for Humanity now celebrates the occupancy of the program’s first LEED Silver certified homes in San Pedro, CA.
Begun during the 2007 Jimmy Carter Work Event over six days last year, 16 local families now enjoy the fruits of their labor - homes built alongside more than 5,000 volunteers. Not only are the homes LEED Silver, but they have another enviable feature: they include access to solar energy. Collectively, the families’ energy bills are expected to be reduced by $200,000 over time (keep an eye out for a related story about the innovative installation at CleanTechnica.)

Chosun University may have the hottest male and female college dorms in the world — if you’re talking solar energy.
Atop both the men’s and women’s dorm a 25 kilowatt solar system pumps out energy. The combined electricity generation of the two buildings is an impressive 50 kw.
The dorms are connected to the energy grid of Gwangju city, where the university is located. When the buildings make more energy than students use, excess energy flows into the city’s grid. When students use more than the solar systems can produce (say, due to post-final exam parties), the dorms simply top up with energy from the city’s supply.

Manufacturers of photovoltaic (PV) solar panels know the panel’s theoretical efficiency, but it’s much more difficult to tell the actual efficiency. For this, solar companies send their panels to a lab for testing under real weather conditions.
Recently, I visited such a solar testing lab — the Solar Power Research Lab at Chosun University in Gwangju, South Korea. I was greeted by Mr. Choi Jong-sik, an engineer and a graduate of the department.
Out front of this lab, a small field of solar panels soak up sunlight. The panel’s designs range from flat to arched and even rotating; some are varicolored polycrystalline, others are neatly lined monocrystalline. Rotating panels have tracking devices that follow the sun (pictured here). The panels can rotate 180° and swivel vertically 53°, following the sun’s path across the sky. The array and variety of panels is stunning.

The iconoclastic owner of the San Jose tract home featured in this article takes exception to the notion that green is expensive. Green, to him, is rooted in conservation of all resources, not the least of them being money.
Frank Schiavo’s compact, tract-built, three-bedroom ranch-style home in a modest San Jose neighborhood demonstrates that remodeling to create a cutting-edge green home is neither difficult nor expensive. Heated with sunlight and cooled by night air, his home is comfortable, quiet and tasteful, filled with light and local art. With only modest investments in a sun room, extra insulation, new windows, a very small array of rooftop photovoltaic and solar hot water panels, his electricity bill for the coldest, cloudiest months of the year averages a few dollars a month. His gas bill is even more modest.
What’s most impressive about Schiavo’s house isn’t that it’s so comfortable and practical for him to own, it’s that it demonstrates that lofty resource conservation goals can be achieved on a modest remodeling budget.

Solar System Powers Donggwang Green Village on Semi-Tropical Jeju Island
Donggwang is on the western half of Jeju-do, the largest of South Korea’s semi-tropical southern islands. Near the village, Halla Mountain, a volcano and the tallest mountain in South Korea, rises from the island’s center amidst a patchwork of small farms.
Donggwang has achieved what even the most powerful countries in the world are still struggling to accomplish: total energy independence with clean technology.

Gary GerberLast week I spoke with Ryan Chao, director of Satellite Housing in Berkeley, CA about a new project that featured solar energy. Today, my guest is Gary Gerber, President and Founder of Sun Light and Power, the company that installed the solar array for Satellite Housing.
Gary founded his company in 1976, and he tells the story of what happened to solar power, and how
