Sempra Generation, a subsidiary of Sempra Energy in San Diego, just took the wraps off a 10-megawatt solar farm in Nevada. That's small by industry standards, enough to light just 6,400 homes. But the ramifications are potentially huge. A veteran analyst has calculated that the facility can produce power at a cost of 7.5 cents a kilowatt-hour, less than the 9-cent benchmark for conventional electricity. If that's so, it marks a milestone that renewable fans have longed for: "grid parity," in which electricity from the sun, wind or other green sources can meet or beat the price performance of such carbon-based fuels as coal and natural gas.

Making your home more energy efficient can not only save you big bucks in 2009, but also put money back in your pocket.
Finz Seafood & Grill shows how any restaurant can use their own waste vegetable oil to generate electricity and hot water at their back door
The engineering company CH2M Hill is now joining hands with the U.S. Department of Energy to provide Internet solar maps of 25 American cities, using Google Earth technology to chart the precise solar potential of neighborhoods, literally rooftop by rooftop. The company has just finished mapping all of San Francisco, allowing residents to enter their address and take the solar measure of their own home. "People in San Francisco think we don't have any solar potential,' says Gavin Newsom, the city's deep-green mayor. "But the map shows we have a lot more sun than you'd believe." Time Magazine Source.
From Wired Science - Green technology was hot in 2008. Barack Obama won the presidential election promising green jobs to Rust Belt workers. Investors poured $5 billion into the sector just through the first nine months of the year. And even Texas oilmen like T. Boone Pickens started pushing alternative energy as a replacement for fossil fuels like petroleum, coal and natural gas. Green technology and its attendant infrastructure are probably the best bet to drag the American economy out of the doldrums. So, with the optimism endemic to the Silicon Valley region, we present you with the Top 10 Green Tech Breakthroughs of 2008, alternatively titled, The Great Green Hope.

Erin's Pavilion is on its way to becoming one of the most accessible and environmentally-friendly welcome and visitor centers in the country. With the installation of the structural steel and Insulated Concrete Form walls completed, the facility is on pace to open in June 2009.
The RF module fitted to each lantern enables flash synchronisation without the need for a base controller. This latest innovation is designed to offer a low-cost synchronisation option for applications including rivers, estuaries, marina entrances, channel marking and aquaculture.
Carmanah Technologies Corporation has introduced a wireless solar-powered flashing beacon suitable for a range of ITS (intelligent traffic systems) roadway applications.
Carmanah Technologies Corporation received the CanSIA "Solar PV Project of the Year Award" for a grid-tied solar power system installed on the Jean Canfield Building in Charlottetown, Prince Edward Island.
Without a radically expanded and smarter electrical grid, wind and solar will remain niche power sources. To make use of clean energy, we'll need more transmission lines that can transport power from one region to another and connect energy-hungry cities with the remote areas where much of our renewable power is likely to be generated. We'll also need far smarter controls throughout the distribution system--technologies that can store extra electricity from wind farms in the batteries of plug-in hybrid cars, for example, or remotely turn power-hungry appliances on and off as the energy supply rises and falls.

The Partnership for Advancing the Transition to Hydrogen (PATH), an international coalition of national hydrogen associations, will now represent the emerging economies of China and Malaysia, adding to the gains the hydrogen industry has made globally throughout 2008.
The City of Burbank has been selected as a national test market for a new zero-emissions, ultra-quiet prototype bus that uses a hydrogen fuel cell instead of a diesel or gasoline engine. The breakthrough vehicle will be unveiled in a spring 2009 Downtown Burbank ceremony and then go into immediate service on various routes within the City's BurbankBus network. Designed and fabricated by Colorado-based Proterra, the revolutionary vehicle can travel 250 miles before needing to be recharged, runs at double the fuel economy of a diesel bus and releases nothing but water from the engine exhaust. In addition to being created and built in this country, it relies on power that is 100% derived from U.S. sources, thereby reducing dependence on foreign energy. [read more]

Solar & Wind - Featured Product
In the monitoring of large photovoltaic (Utility Scale), in assessing potential sites (Solar-assessment), or in up and coming electricity cost saving initiatives projects (Commercial & Industrial), the WS510 now provides the market a secondary standard pyranometer, ultrasonic wind speed, ultrasonic wind direction, temperature, pressure and humidity all in a single unit.. This sensor meets the high demands of the world meteorological organization (WMO) through the active valving at air temperature measurement and the inertia- and maintenance-free measurement of wind speed and wind direction on the ultrasonic principle. Equipped with a Kipp & Zonen pyranometer of the secondary standards, the WS510-UMB Compact weather sensor from Lufft unites the precision of a variety of meteorological individual sensors in a single all-in-one device, for the first time.
