Review - "An Inconvenient Truth"

One does not have to absorb or completely believe all that is presented to make "An Inconvenient Truth" one of slickest, and most palpable documentaries to come out of Hollywood for quite some time.

Solar: The No-Risk Path to Wealth Creation

While all investments pose some degree of risk, the return on a solar energy system is about as safe and predictable as, well, the rising sun. Fortunately for the Earth and its varied inhabitants, the center of our solar system is situated well beyond the reach of humanity's capacity to tamper with a good thing.

Taking the Green Route with Fuel Cell Buses

Fuel cell buses appear destined to be a major part of transit fleets, reducing petroleum dependence and providing a truly zero emission mobility option.

Water Conservation & Xeriscape Conference

The Expo now draws over 3,000 residents to a free day of seminars, demonstrations, and exhibits for both adults and children.

Wind Energy Collection using Contra-Rotation

Contra-rotation, using two rotors one behind the other, driving the two halves of an electrical generator. Thus creating a true "Wind Turbine".

Back to the Future With Plankton Power

Ocean plankton restoration offers a powerful remedial approach to global warming that also rescues critical ecosystems, profitably finances itself, and can help allay further resistance to CO2 regulation based on economic qualms.

Commercial Hot Water Technology Offers 400% Efficiency

The system is connected to refrigeration grade tubing that is placed in direct contact with the renewable heat source in the upper 100 feet of the earth's surface. The ground temperature is stable year round, and in the U.S., ranges from 42 degrees at the Canadian border to 78 degrees in the southern extreme.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
