Ultracapacitors prove to be a high-reliability solution for the severe power pulses needed for wind turbine pitch control.
Parishioner Donation Sparks Solar Electric System Installation At St. Frances Cabrini Catholic Churc
Starting with an anonymous donation and some bright ideas from a design consultant, combined with the ambition and organization of parish staff, and the helping hands of 17 women and an environmental business; this system is truly a symbol of what collaborative team effort can do for sustainable development.
The small hybrid solar and wind energy system at NREL's Outdoor Test Facility produces 1,400 watts of power from solar and 900 watts from the wind turbine, enough to power a refrigerator, lights, heaters, air coolers, computers and a radio.
The sun has always been growing the grapes for California wineries. Now, with cost-effective solar electric systems, the sun can grow their bottom line, too.
Solar Data Centers is the first company in the world to employ solar energy to run every aspect of an organization's Internet operations.
With a little thought and preparation, you can solve many of your electrical needs safely in the event of an extended power outage. The do-it-yourselfer might want to make their own portable solar power supply, or put a 12 volt motor in a small swamp cooler to solve those electrical needs.
CANMET tests have shown that this renewable biomass fuel log produces 94% less CO and 84% less Particulate Matter emissions than cordwood.
"Every time an expert tells me it can't be done, I sit back, peel one of my oranges, and marvel at my ability to eat something that is impossible to grow in Nebraska."
Eskom has gone to lengths to make this installation blend with the environment. Virtually no real estate is taken up (farming can be done right underneath the units) and standing under windmills of this size not unpleasant at all ... even the cows seem to like the gentle swishing sound they make ... as witnessed by the locations of their deposits :-)
EcoEnegies helps congregation Shir Hadash go solar.
This huge residential system was a great success for the Laursens, and for Sierra Solar Systems who provided the equipment. The family has now completely eliminated their high utility bill and will be powering their home for generations to come with clean renewable energy. In addition, local wildlife will receive the benefit of a year-round drinking supply.
As onlooking eyes filled with wonder watched, I assembled the three solar panels to the framework, it was time to hoist the finished array onto the roof. We were on the front side of the clinic and the ladder was not very good. We got the array to the top of the ladder but I could not get my helpers to go up on the roof.

The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach - coupling energy storage to PV arrays with a DC-to-DC converter - can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
