Does the Public Sector already hold the key to delivering energy efficiency?

So implementing energy efficiency measures sounds like a good idea in principle, but how can local authorities or municipalities balance the equation of technology costs and fund the capital expenditure? Put simply, some of the measures that can be implemented deliver savings immediately with payback periods that are very short - in some instances only 6 months. However; to address a set of larger scale measures, the answer comprises 3 elements: i) scale of project, ii) guaranteeing savings through energy performance contracting and iii) access to competitive (low interest rate) finance.

Solar Cogeneration - The highest utilization of the sun's resources

Solar cogeneration combines proven photovoltaic (PV) and solar thermal technologies to maximize total collected energy and optimize economic benefits for institutional, commercial and industrial customers. Using up to 80 percent of the sun's delivered energy

Key Issues In the Clean Tech Industry: The Role Of Public Relations

Once of the greatest barriers to the adoption of new clean technologies is the upfront cost, with the resulting sticker shock sending consumers running. Many clean tech firms offer attractive financing packages, but fall down on marketing them effectively, or -- on an even more basic level -- adequately explaining them.

U.S. wind growing again, but business still choppy

The U.S. wind industry is growing again after taking a big step backward last year. Yet turbine makers and wind farm developers are finding few reasons to celebrate as the clean energy source struggles to secure long-term government support while facing stiff competition from cheap natural gas. Once the world's top wind market, the United States ceded that mantle to China last year as a weak economy halted its growth and cut new installations to half of the 10,000 megawatts of capacity built in 2009. Since then, business has picked up, but not for the reasons the industry would like. Energy demand is still tepid due to a gurgling economic recovery, and the low cost of natural gas is keeping power prices low. Pricing in long-term power sales contracts signed by wind developers has fallen 30 percent in the last two years and will fall further this year, according to IHS Emerging Energy Research. Currently, the market is being shepherded by developers who are scrambling to put turbines in the ground ahead of a 2013 expiration of lucrative federal tax credits for wind. Beyond that date, the industry's fortunes are hazy.

U.S. gets World's Largest Wind-Blade Testing Facility

Boston, Massachusetts (USA) saw the opening of the world's largest large-scale wind turbine blade testing facility this week. The Wind Technology Testing Center—in partnership with the U.S. National Renewable Energy Laboratory—can test blades up to 90 meters long, which is expected to be the industry's largest blade size in coming years. Prior to the facility's opening, domestically produced large-scale wind turbine blades had to be shipped outside of the U.S., usually to Europe, to be tested. The largest predecessors in the U.S. to the Wind Technology Testing Center could only support turbine blades no longer than 50 meters. The facility has the capacity to test up to three blades simultaneously. Standard tests measure fatigue through a four-month endurance process. Two-week-long static strength and resonance testing are also commonplace. The Wind Technology Testing Center itself took roughly two years to build at a cost of just under $40 million. $25 million was awarded by the U.S. Department of Energy as part of the 2009 American Recovery and Reinvestment Act. $13.2 million in additional funds was provided through loans and grants furnished by the Massachusetts Renewable Energy Trust.

Landis+Gyr at Any Price? Smart Meters' Second Act

Landis+Gyr is said to be on the auction block — and big smart grid suitors have come to bid. Reuters has reported that General Electric was offering $2 billion for the Swiss-based smart metering giant, an offer that was followed by Toshiba's 200 billion yen ($2.48 billion) counter-offer, and entry by strategic bidders including Honeywell and ABB. And while some reports say GE had withdrawn its bid, I've heard that GE is very much still in the running. Landis+Gyr earned about $200 million on about $1.5 billion in annual revenues in the last year, Reuters' anonymous sources report. That puts a $2 billion-plus price firmly in the realm of long-term investment. But strategic buyers could squeeze a lot more value out of L+G by integrating its existing technologies and utility projects into their own lines of business. For example, GE's smart meter business relies on a host of partners for communications and networking, while L+G has its own 900-megahertz communications system, as well as back-end software to manage it all. With L+G, GE could stop just churning out smart meters like widgets, and start supplying a more holistic offering to utilities.

Chevy Volt to be assembled at solar-powered plant

In its first year the Chevrolet Volt has garnered several awards, including 2011 Motor Trend Car of the Year, Green Car Journal's 2011 Green Car of the Year, and Automobile's 2011 Automobile of the Year. And now the electric car with extended range is going to be built in a solar-powered facility. General Motors announced it is building the photovoltaic solar array, the largest in Southeast Michigan, at the Detroit-Hamtramck assembly plant. Sunlight will help to create the $41,000 Volt. Once it's completed, the 516-kilowatt project built by GM and DTE Energy will generate 54,750 volts. Plus, the 6-acre land tract will generate 15 megawatts of electricity throughout Southeast Michigan. According to GM, the U.S. automaker will save about $15,000 a year over 20 years with the 264,000-square-foot array. DTE is investing $3 million into the project.

DOE Wrapping Up Renewable-Energy Project Loan Guarantee Program

The U.S. Department of Energy said Tuesday that it has stopped accepting applications for loan guarantees to help finance new solar, wind or other renewable energy facilities and suggested there would be winners and losers among companies that have applications pending. The loan guarantee program for renewable energy generation projects, called "Section 1705," after the portion of the 2009 Recovery Act that supports it, expires Sept. 30 and only projects that can start construction and close their loan guarantees by that date will be considered for a guarantee, Jonathan Silver, the head of the agency's loan programs office, wrote in a blog post on the DOE web site. The agency has issued roughly $1.6 billion in loan guarantees for 19 renewable energy projects to date. Loan guarantees for roughly $800 million in remaining funds will be issued to companies that have already applied, whose applications are "farthest along in the process," and whose projects are most likely to meet the Sept. 30 construction deadline, Silver wrote. "Not all these projects will succeed by September 30th," he wrote. The DOE placed another group of applications "on hold" after determining that the projects were unlikely to meet the Sept. 30 deadline, Silver wrote. He added that if the program received more funding in the future, those applications could be revived. The DOE notified companies on Tuesday whether their applications would proceed or not, Silver wrote.
