These States Are the Early Leaders in the US Energy Storage Market

Eric Wesoff for GreenTech Media:  Energy storage is a small market experiencing fierce growth. The U.S. installed 61.9 megawatts of energy storage in 2014, and GTM Research is forecasting 220 megawatts to be installed in 2015. But, as with the U.S. solar industry, energy storage projects are clustered in states with incentives or in regions where markets are able to place a value on storage.    So it's no surprise that California, Hawaii, and New York have assumed early leadership in energy storage by virtue of their unique incentives, mandates and markets, according to the inaugural GTM Research and Energy Storage Association U.S. Energy Storage Monitor report.   Cont'd...

See-Through Solar Is Tomorrow's Threat to Oil

The engineers at Ubiquitous Energy are developing solar panels that are completely transparent and as thin as a laminate. They can do this by creating see-through solar cells that absorb only the invisible parts of the solar spectrum—ultraviolet and infrared radiation. The technology still has a way to go because the cells must become more efficient to prove cost-effective, but their promise is big: solar cells that could become a part of any glass or plastic surface. They could sit, invisibly, atop a smartphone’s display, allowing the phone to charge itself under natural or artificial light. And if the process became part of glass and window manufacturing, homes and skyscrapers could draw power from the sun without the spatial and aesthetic limits of current, opaque solar panels.

US Energy Storage Market Could Triple This Year

The energy storage market is poised for substantial growth over the next five years, with installed capacity this year expected to more than triple to 220 MW from last year’s 62 MW.   A recent report from GTM Research and the Energy Storage Association, ‘U.S. Energy Storage Monitor,’ projected that the market will grow from $128 million last year to $1.5 billion by 2019, when more than 800 MW will be installed.   Moreover, non-utility storage – residential and non-residential – will grow from just 10% of installed capacity last year to 45% over the same period.   This is a bullish forecast for downstream residential vendors identified in the report, such as Schneider Electric, Outback Power, Sunverge, and Solar City.

Texas City Pulls Plug on Fossil Fuels With Shift to Solar Power

Christopher Martin for Bloomberg:  A Texas city just north of Austin plans to begin weaning its residents from fossil fuels.   The municipal utility in Georgetown, with about 50,000 residents, will get all of its power from renewable resources when SunEdison Inc. completes 150 megawatts of solar farms in West Texas next year. The change was announced Wednesday.   It will be the first city to completely embrace clean power in the state, which is the biggest U.S. producer and user of natural gas. More will follow as municipalities seek to insulate themselves from unpredictable prices for fossil fuels, said Paul Gaynor, SunEdison’s executive vice president of North America. Burlington, Vermont, made a similar move with its purchase of a hydroelectric plant last year.   “This will be the first of many,” Gaynor said in a telephone interview. “The city is making a judgment that they want to enjoy a stable electricity price.”

Harvesting solar power in space one step closer

From  Tereza Pultarova for E&T Magazine:  Japanese engineering giant Mitsubishi has successfully demonstrated wireless power transmission over a larger distance paving the way for harvesting energy in outer space. During the test at Mitsubishi Heavy Industries’ Kobe Shipyard & Machinery Works facility near Osaka, the engineers managed to beam 10kW of power through a microwave transmitter across a 500m distance.   As the beam of microwaves hit the receiver and got converted back into energy, its LED lights turned on using the received power.   Mitsubishi said the test ‘marks a new milestone’ in terms of both, the distance and power load, and verifies the firm’s space solar power systems (SSPS) concept.   Mitsubishi envisions SSPS will take solar energy generation to an entirely new level. Solar panels would be placed at geostationary satellites, which hang above a fixed spot above the Earth’s surface at the distance of 36,000km, and unhindered by Earth’s atmosphere would generate energy much more efficiently.   The wireless transmission system, freeing energy generation from the reliance on cables and wires, would then beam the energy to Earth using a microwave or laser technology.   Mitsubishi believes space-based solar power will revolutionise renewable energy generation and will in future become the world’s number one source of clean renewable power.

Upcoming solar eclipse to wreak havoc on Germany's solar power output

By Andrew Freedman for Mashable: The partial solar eclipse slated to take place throughout Europe on March 20 may delight skywatchers, but it's presenting a significant headache for the operators of Germany's electricity grid. The country is a world leader in solar energy, boasting a huge edge over the U.S. in installed solar power generation.   When the eclipse occurs between about 9:30 a.m. and 12 p.m., local time, on the 20th, electric utilities in Germany will have to contend with rapid swings in energy production. First, there will be a steep drop-off in generation, followed by a sudden spike.   These fluctuations, and how utilities choose to cope with them, provide a preview of what utilities in the U.S. and other nations face, as renewable energy production soars in coming decades, according to an analysis from Opower, a software company that uses data to help utilities improve the customer experience.   Germany gets about 7% of its electricity each year from solar panels, compared to 0.5% in the U.S., according to Barry Fischer, a writer and analyst at Opower. On the sunniest days, Germany can meet half of its electricity demand through solar power alone, he told Mashable in an interview.  

Solar-Power Plane Airborne on Historic Round-the-World Trip

With its wings stretched wide to catch the sun's energy, a Swiss-made solar-powered aircraft took off from Abu Dhabi just after daybreak Monday in a historic first attempt to fly around the world without a drop of fossil fuel. Solar Impulse founder André Borschberg was at the controls of the single-seat aircraft when it lumbered into the air at the Al Bateen Executive Airport. Borschberg will trade off piloting with Solar Impulse co-founder Bertrand Piccard during layovers on a 35,000-kilometer (21,700-mile) journey. Some legs of the trip, such as over the Pacific and Atlantic oceans, will mean five days and five nights of flying solo. Both pilots have been training hard for this journey, which will span 25 flight days over five months before this Spruce Goose of renewable energy returns to Abu Dhabi in late July or August. "It is also exciting because you know, you simulate, you calculate, you imagine, but there is nothing like testing and doing it in real," Borschberg said just hours before takeoff. "I am sure we are all confident and hopefully we will be able to see each other here in five months." The Solar Impulse 2 aircraft, a larger version of a single-seat prototype that first flew five years ago, has a wingspan of 72 meters (236 feet), larger than that of the Boeing 747. Built into the wings are 17,248 ultra-efficient solar cells that transfer solar energy to four electrical motors that power the plane's propellers. The solar cells also recharge four lithium polymer batteries.

Nexus eWater Completes $2.1 Million Series A Funding Round

Nexus eWater has developed the world's first practical water and energy recycler for homes. The estimated annual US market for this new product suite is projected at $15 billion per year. The patented product collects a home’s grey water (the drain water from showers and laundry), then cleans it to the highest standard for at-home recycling for lawn watering and other approved uses. Additionally, the system captures and re-uses the heat found in the grey water for further recycling. The system is available for both new homes and for retrofits.   The international investor team includes Canberra-based venture fund ANU Connect Ventures (ANUCV), the Sydney Angels and the Sydney SideCar Fund. The round was led by Thomas Reeves Hitchner, the retired general partner of Baltimore-based venture fund, QuestMark Partners. Proceeds from this funding cycle will complete the initial product roll-out of Nexus’ on-site water and energy recycling products for the California and US market.   The Nexus system is affordable, robust and efficient. It is a sustainability “triple play.” For a house with a family of four, the system provides these three benefits: Reduces in-home water usage by 40%, (up to 200 gallons per day) by recycling 67% of the water used in a house; Reduces wastewater by 70%, (up to 200 gallons per day); and Reduces home electric energy usage by 10-20%. The energy recycler provides the equivalent power of a 1.5 kW solar array, but at a fraction of the cost. In large, older homes, this amount could be tripled. Energy recycling is accomplished by using a patented heat pump system, which harvests the energy from the warm grey water and then uses that energy to heat fresh, new water for the home. By recycling this energy, the home’s water can be heated using 75% less energy than any conventional tank or tankless water heater.  

Japan's Growth in Solar Power Falters as Utilities Balk

By JONATHAN SOBLE for NY Times:  Rice fields, golf courses and even a disused airport runway. All over the southern Japanese region of Kyushu, unexpected places gleam with electricity-producing solar panels.   Solar use in Japan has exploded over the last two years as part of an ambitious national effort to promote renewable energy. But the technology’s future role is now in doubt.   Utilities say their infrastructure cannot handle the swelling army of solar entrepreneurs intent on selling their power. And their willingness to invest more money depends heavily on whether the government remains committed to clean energy.   “It’s upsetting,” said Junji Akagi, a real estate developer on Ukushima, a tiny island near Nagasaki. Mr. Akagi said he hoped to turn a quarter of the island’s 10-square-mile area into a “mega-solar” generating station, and has already lined up investors and secured the necessary land.   Then last September, Kyushu Electric Power Company, the region’s dominant utility, abruptly announced that it would stop contracting to buy electricity from new solar installations. Other power companies elsewhere in Japan soon followed suit.

Floating Solar Panel Project Due in 2016 from California Power Company

From GovTech.com:  Sonoma County, Calif.'s new public electricity supplier is turning to the sun and water — the airspace over treated sewage ponds, specifically — to generate power for local homes and businesses.   Under a deal signed Thursday with a San Francisco-based renewable energy developer, officials with Sonoma Clean Power, now the default electricity provider in Sonoma County, unveiled a plan to install a 12.5-megawatt solar farm on floating docks atop holding ponds operated by the county Water Agency.   When completed in 2016, the project, which will provide enough electricity to power 3,000 homes, will be the largest solar installation in the county. It also will help fulfill one of Sonoma Clean Power’s central goals — to develop local sources of renewable energy for its expanding customer base, now taking in more than 160,000 residential and commercial accounts across five cities in the county.  

Spray-on Solar Cells - How do they Work?

Spray-on solar cells use nanotechnology. These cells are made using quantum dots, which is a nanocrystal composed of a semiconductor material that is small enough to take advantage of the laws of quantum mechanics.

Deutsche Bank MD expects Cost of Solar to Drop Another 20-30% as 2020 Approaches

The US and China will be in the 12-15 GW range in 2015 but the incremental growth will come from some of these emerging markets. We expect Mexico to be a 2 GW market by 2017, with South Africa also above the 1 GW mark by 2017. These two markets were stagnant in 2013-14, so the growth will be quite significant in the coming years.

The Eiffel Tower now generates its own power with new wind turbines

France's most recognisable landmark, the iron Eiffel Tower erected in 1889, has seen its iconic frame festooned with many different decorations and objects over the years for various celebrations. Its latest addition is a little more subtle -- and maybe a little more in keeping with the tower's original purpose as a monument to human ingenuity and artistry.   As part of a major renovation and upgrade to the tower's first floor, the Société d'Exploitation de la Tour Eiffel will be adding a variety of sustainability features -- the first of which is a pair of VisionAIR5 wind turbines designed by renewable energy specialist Urban Green Energy.   The two vertical-axis turbines have been installed on the tower's second level, about 122 metres (400ft) from the ground -- a position that maximises wind capture. The turbines have been specially painted so as to blend in with the tower, and produce virtually no sound. They can also capture wind from any direction, producing, between them, a total of 10,000kWh per year -- enough to power the tower's first floor.
