Fortune Online has an article about how San Jose hopes to reduce the $3.5 million spent annually to light it's streets by replacing sodium lights with low-energy LED and by monitoring the whole system through a smart network. The 125-light test, due to launch this summer, will be implemented by hometown smart-grid company Echelon (ELON). The streetlight network will function in a similar way to a smart electricity grid. Using the city's wi-fi network, Echelon's networking technology enables the lights to transfer real-time data about the status and performance of any given bulb. That way, maintenance crews won't have to search for a fried bulb. The city will be able to monitor energy consumption, anticipate outages and dim lights to save energy at the flip of a master switch. Complete article.
A funny thing happened on the way to oblivion - for many scientists today, cold fusion is hot again. "We can yield the power of nuclear physics on a tabletop. The potential is unlimited. That is the most powerful energy source known to man," researcher Michael McKubre told 60 Minutes correspondent Scott Pelley. McKubre is an electro-chemist who imagines, in 20 years, the creation of a clean nuclear battery. "For example, a laptop would come pre-charged with all of the energy that you would ever intend to use. Watch the entire 60 Minutes story here.
Livermore Cinemas in Livermore, Calif., now has a fully operational 132 kW rooftop system which produces 190,000 kilowatt-hours per year to help power the all-digital multiplex cinema. The SPG Solar system offsets 45 percent of the facility's electric use. According to the US Environmental Protection Agency, this system will prevent the emissions of more than 3,400 metric tons of greenhouse gases, which is equivalent to removing 625 passenger cars from the road for a year.
One of the world's biggest photovoltaic projects is planned for southwest Florida. Florida Power & Light will spend $350 million to build a 75-megawatt photovoltaic solar plant at a planned city, Babcock Ranch, near Fort Myers. The plant could be the largest in the world if it reaches 75MW output--before somebody else does. Photovoltaic cells convert sunlight into electricity. Electric vehicles, able to plug in for recharge at convenient community-wide recharging stations, will glide along avenues beneath the glow of solar-powered street lamps.
As momentum gathers for the creation of an Internet-like "smart grid" that will do for the electricity grid what the Internet did for home shopping, the WSJ reports the cyberspace wars have begun. The big question is whether the move to a smart grid would increase the country's vulnerability to cyber attacks, or serve as the best form of defense. California-based Electric Power Research Institute has been selected by the Commerce Department to draw up the "roadmap" of the new smart grid. Its main task will be figuring out just what standards should prevail in that brave new world.
Germany's Reichstag in Berlin is set to become the first parliamentary building in the world to be powered 100 percent by renewable energy. Soon the entire country will follow suit. Germany is accelerating its efforts to become the world's first industrial power to use 100 percent renewable energy -- and given current momentum, it could reach that green goal by 2050. A new Roadmap published by the German Federal Ministry for the Environment sketches out the route the world's largest exporter plans to take to switch over completely to renewable energy, and add 800,000 to 900,000 new cleantech jobs by 2030 as it does so.
General Motors will make another push into the realm of alternative vehicle technology through a joint venture with Segway Inc. to produce a two-wheeled upright personal transporter. The auto maker is targeting a 2012 launch for its electric-powered PUMA transporter, which would also employ wireless technology to allow users to navigate in urban areas and avoid traffic congestion. A prototype of the PUMA - which stands for Personal Urban Mobility and Accessibility - will take to the streets of Manhattan this week during the New York auto show .
Italy installed a national smart grid before the term was even coined. The Italian utility Enel has installed 30 million smart meters since 2001, and it estimates savings at $6.74 million a year. The savings that come from smart grid technologies, however, aren't always easily predicted. In Italy, for instance, the money in homes saved doesn't come through demand response programs. Instead, it comes because the utility can deliver electricity at lower voltages to homes because of the meters and because of phase balancing, a process that better matches the output from the utility with the usage patterns of homes.
The Clean Tech Open , the innovation catalyst that helps great ideas become viable clean tech businesses has challenged entrepreneurs, venture capitalists, government agencies, universities, and non-government organizations (NGOs) to participate in the Clean Tech Open's 100K Jobs Challenge - to create 100,000 clean tech jobs in America over the next five years. The leading clean tech business competition has already helped more than 120 entrepreneurs launch companies-and subsequently raise over $125 million in external funding-since its inception in 2006.
As part of a market liberalization plan, 80% of European households will be outfitted with energy-saving 'smart' utility meters over the next decade. Some 80 percent of European consumers are set to have smart energy meters installed in their homes by 2020 as part of a deal on liberalising the EU's energy market. This will allow them not only to carefully screen and control energy consumption, but also to sell energy back to the network, for instance by installing solar panels on the roof.
U.S. homeowners might start seeing energy monitoring services being offered alongside "triple-play" TV, phone and Internet service as early as this year. Think of it as a "smart home" incentive to get people to buy telecom broadband services. The question, of course, is whether homeowners will want to pay what telecoms will want to charge to make it worth their while.
The European Photovoltaic Industry Association (EPIA) presented its annual market figures to its members on Friday 20 March 2009. The global solar photovoltaic (PV) market grew to at least 5.5 GW in 2008 compared to 2.4 GW in 2007. Spain ranks first, followed by Germany. This year, experts believe the market could reach up to 7 GW, each individual country's development influencing the final figure.
The Solar Energy Industries Association released its 2008 U.S. Solar Industry Year in Review , highlighting a third year of record growth. SEIA reports 1,265 megawatts of solar power of all types were installed in 2008, raising total capacity 17 percent to 8,775 MW. The 2008 figure included 342 MW of solar photovoltaic (PV), 139 MW of solar water heating, 762 MW of pool heating and an estimated 21 MW of solar space heating and cooling. SEIA President and CEO Rhone Resch: "Despite economic pressures, solar energy demand grew tremendously in 2008. Solar is an emerging economic engine, creating thousands of jobs, unleashing billions in investment and building new factories nationwide.
On the second day of his tour of Southern California, President Obama highlighted his environmental jobs agenda with a visit to an electric-vehicle testing facility in Pomona, where he announced a $2.4-billion competitive grant program to make the electric vehicles more widely available . As a receptive audience of engineers and workers cheered his plans, Obama pledged to put a million plug-in hybrid vehicles on the road by 2015, and highlighted his offer of up to $7,500 in tax credits for Americans who purchase electric vehicles.
Consumers have heard for years that solar, wind, and geothermal power might soon cut their monthly energy bills. But things get exciting, even exotic, looking a decade or two ahead . Scientists envision that light bulbs will talk to switches, furnaces to windows, and everything to the Internet. Homes generate their own power in basement plants. Windows and paint change color to harvest sunlight or reject it. But ... cutting home energy use means changing consumer behavior and industry practice. That said, promising new technologies are emerging in labs, and some in commercial buildings, that in a decade or two could win over even the most skeptical builders and homeowners.

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.
