Cree LRP-38: The LED replacement for halogen
PAR38s
Available in volume, the energy-efficient Cree
LRP-38 has a power input of only 12 Watts. The Cree LRP-38’s low heat,
low UV, and exceptional color quality—a CRI of 92 @ 2700K—is
designed to replace 50W–90W halogen PAR38s in retail and display
settings and last 50,000 hours in open track fixtures.

A Reuters
report said several large solar manufacturers recently announced
plans to build manufacturing plants in the United States to produce PV
modules. Kyocera plans to build a plant in San Diego; Suntech wants to
build a PV panel plant in Arizona; and Yingli Green Energy is
considering factory sites in Austin, Texas, and Phoenix. A March
6 article in the Phoenix Business Journal offered additional
insight into this trend. The Reuters article said Kyocera expects
its San Diego plant to produce 30MW per year, and that one megawatt can
power approximately 800 homes.

Ballard Power Systems, Burnaby, British Columbia, has entered into
contracts for the supply of fuel cell power modules to power two
different transit bus configurations at the SunLine Transit Agency in
Thousand Oaks, Calif. Under the Advanced Technology (AT) program,
Ballard, ISE Corporation and New Flyer Industries have struck a deal
that will provide SunLine Transit with a 40-foot fuel cell hybrid bus
powered by Ballard's FCvelocity(TM)-HD6 power module, similar to the 20
buses currently being operated in Whistler, B.C. This bus has been
delivered and will be entering regular transit service in 2010.
Thirty-six Ballard-powered fuel cell buses have operated on roads in
Europe, Australia, China and the United States. Vehicles like this
Mercedes-Benz Citaro bus in London, England (one of 33 in Daimler's fuel
cell bus fleet), are providing Ballard with valuable information about
how fuel cell-powered buses perform in different geographies and
climates. Details

Energy Secretary Steven Chu announced conditional commitments for
more than $1.37 billion in loan guarantees under the American Recovery
and Reinvestment Act to BrightSource Energy Inc. to support the
construction and start-up of three utility-scale concentrated solar
power plants. The new plants will generate approximately 400MW of
electricity. This would nearly double the existing generation capacity
of this type of renewable energy in the U.S. The three-plant Ivanpah
Solar Complex will be located on federally-owned land in the Mojave
Desert in southeastern California near the Nevada border and will be the
world’s largest operational concentrated solar power complex. Once
operational, the project will supply clean electric power to
approximately 140,000 California homes. Details

EMCOR Energy Services, Inc., was recently awarded a nationwide
Blanket Purchase Agreement (BPA) to provide comprehensive energy
services for the General Services Administration (GSA). EMCOR Energy
Services was one of 19 organizations to be awarded a BPA by the GSA, one
of the world's largest building managers. Details

During the past six years, Home Depot, Atlanta, Ga., has reduced
its U.S. stores' energy per square foot consumption by 16 percent. At
the start of 2004, Home Depot's energy usage was 25 kWh per square foot.
Through a series of operational programs including the upgrading of
store HVAC systems, aligning of stocking hours more closely with store
operating hours, use of CFL bulbs and a switch to T5 lighting, the
company's U.S. store energy usage now stands at 21 kWh per square foot.
Moving forward, Home Depot believes it can reach 20 kWh per square foot
of energy usage by 2015. The stores will continue to gain operational
and energy efficiencies through a move from 54W to 49W lighting,
additional HVAC upgrades and installation of more white roofs. All of
these efforts, representing an additional reduction of approximately
five percent from the current usage amounts, will bring the total
reduction since 2004 to 20 percent. Details

Technology consulting firm iSuppli sent up a flare on March 2 about
a possible shortage of LEDs. Huge demand for flat-screen televisions
with LED backlighting is apparently one of the main causes for the
shortage, according to an iSuppli
report. Interestingly, LEDs for general lighting applications are
still a tiny piece of the market pie as far as LED manufacturers are
concerned. Said the iSuppli report, “The general illumination market
for LEDs is still in its infancy, but will become mainstream during the
next two years.”

Bill Watkins, formerly CEO of Seagate Technology, a manufacturer of
hard drives, is now CEO of Bridgelux, a fledgling LED manufacturer.
According to a recent article in the San Jose Mercury News,
Watkins fell in love with LED lighting because of its market potential.

The H4 connector is designed for residential, commercial or
utility-scale solar installations. Its Radsok Contact Technology was
developed by GE for military applications and offers greatly improved
current capacity and lower resistance, with an amperage rating of 30A
and resistance of 25 ohms. Lower resistance means less power loss, a
critical issue for maximum performance in PV systems. The connector
meets 2008 NEC requirements and is UL-listed, TUV-approved and RoHS
compliant. USA Wire & Cable

The EM21 Series is a compact three-phase energy meter with an
innovative detachable, connector-less and battery-less display. The
meter allows users to configure the instrument for panel mounting (72 x
72mm) or DIN-rail mounting, either as an energy meter or a transducer.
The general-purpose three-phase energy meter is suitable for both active
and reactive energy metering for cost allocation, but also for main
electrical parameter measurement and retransmission (transducer
function). As an option, a two-wire RS485 communication port is also
available. Carlo Gavazzi
