IVANPAH, CALIFORNIA, APRIL 02 2013: The top of Tower 1 is "lit" during a steam blow test at the Ivanpah Solar Power Facility. Located in the Mojave Desert 40 miles southwest of Las Vegas, The Ivanpah Solar Power Facility is a solar thermal power project, currently under construction, with a planned capacity of 392 megawatts, enough to power approximately 140,000 houses. It will deploy 170,000 heliostat mirrors spread over 4,000 hectares, focusing solar energy on boilers located atop three solar power towers, generating steam to drive specially adapted steam turbines The project, developed by Bechtel, will cost $2.2 billion and be the largest solar farm in the world (photo Gilles Mingasson/Getty Images for Bechtel).

These retrofitted solar-panel canopies also provide shade for parked vehicles and don't require any more land area than already used by the parking lot. VA Medical Complex, Albuquerque, NM. 24 Jan 2013. (0278)
Installed in 2011. The entire PV system at this medical complex reportedly generates 3200 KW and can provide for up to 20% of the hospital's annual energy needs.
Baltimore City has created the solar powered water wheel, a 100,000-pound trash-collecting device that harness solar power and the current. Debris is funneled into the device and then onto a conveyor belt that deposits it into a dumpster, which is emptied once full.
This solar powered sign on the Bristol and Bath Railway Path monitors the speed of cyclists coming towards Bristol near a crossing for school children. I took this picture at about a quarter past 4 when most of the primary school families had gone home but there were still plenty of people, (including children) on foot and on bikes in the area.
Several people on bikes (like the person here) didn't slow down enough to cancel the sign by the time they had reached the crossing.
I expect that when such people drive cars they take the same "I know better than the people who put up this sign" attitude.
A pity, really.

105 solar panels are installed at Littlestown Veterinary Hospital in Littlestown, PA, in mid September 2010. The Littlestown Veterinary Hospital in Littlestown, PA, received a grant from the U. S. Department of Agriculture, Rural Development under the Rural Energy for America Program (REAP) to have solar panels installed to help reduce their carbon footprint and to have cost effective electric power for the hospital. REAP provides grants for energy audits and renewable energy development assistance. The program also provides funds to agricultural producers and rural small business to purchase and install renewable energy systems and make energy efficiency improvements. The expected cost savings using solar power for the hospital’s electrical needs is expected to reduce the facility’s operating expenses by 50%. Courtesy photo by Julie Holland.

I took a free tour of the Science Barge, a not-for-profit enterprise which is trying to prove that NYC's food needs could be met using renewable energy.
On July 25, the Port began to work on the system’s infrastructure, interconnecting the main electrical grid with the wiring for the new photovoltaic panels.

Local manufacturers were trained in Danish solar power technology, including how to produce, operate, install and maintain solar panels. A new type of solar panel, based on locally available materials, was designed and 75 units were produced, installed and tested in the Tashkent Municipality.
"To date, we have provided 1,500 cubic metres of solar panels to rural medical centres, entrepreneurs and a natural reserve," said Shavkat Isamiddiniv, Director of ENCOM, a private company that produces solar panels.

Demanding good jobs, healthier communities, and frontline justice with 100% clean, renewable energy, hundreds of New Yorkers converged on the State Capitol on Wednesday to call on Governor Cuomo and state lawmakers to support the NYS Climate & Community Protection Act (A.10342) – the nation’s strongest climate protection bill. NY Renews, a historic group of labor, environmental, and grassroots organizations, is coming together for the first time to trailblaze a new front in the fight against climate change – pushing the climate protection debate from an environmental discussion to an economic and social justice one.

Microchip Technology's 14-member dsPIC33EP “GS” family of Digital Signal Controllers (DSCs) delivers the performance needed to implement more sophisticated non-linear, predictive and adaptive control algorithms at higher switching frequencies. These advanced algorithms enable power supply designs that are more energy efficient and have better power supply specifications. Higher switching frequencies enable the development of physically smaller power supplies that offer higher densities and lower costs. Compared with the previous generation of DSCs, the new dsPIC33EP “GS” devices provide less than half the latency, when used in a three-pole three-zero compensator, and consume up to 80% less power in any application.
This new dsPIC33EP “GS” family includes advanced features such as Live Update Flash capability, which is especially helpful for high-availability or “always-on” systems. Live Update can be used to change the firmware of an operating power supply, including the active compensator calculation code, while maintaining continuous regulation. Variants from this new digital-power-optimized DSC family are available in an industry’s-smallest, 4 x 4 mm UQFN package for space-constrained designs.
