OutBack Power Technologies, Inc., a designer and manufacturer of advanced power electronics for renewable energy, backup power and mobile applications, will showcase its newest Radian Grid/Hybrid solar systems at PCBC, June 25 to 26 in San Francisco. Supported by smarter technology, including the new GridZero Radian inverters, energy storage options, and OPTICS RE mobile monitoring and control application, these next-generation solar systems deliver both renewable economics and energy independence to homeowners, installers and builders. The result is increased customer satisfaction through reduced anxiety concerning solar investment in the midst of changing utility policies, and remote system control for installers reducing the need for costly service calls. Until now, solar users fell into two categories: off-grid, but with limited electrical use; and grid-tied with the ability to save money when the sun is shining, but with no option for power during outages or emergencies. OutBack Power's Grid/Hybrid systems with energy storage offer the best of both worlds: Homeowners can choose to go off-grid and store unused energy for future use, or use the grid as their backup when they need extra electricity beyond what their system can produce.
It's crazy. It'll never work. They cost too much. They'll crack. They're too delicate. You'll slide off them. Oil companies will never let it happen. Scott Brusaw, an electrical engineer from Idaho, has heard it all before. Over the past eight years, skeptics (like this one) have been telling him his concept for solar roadways — replacing America's roads with solar panels, creating a power grid where pavement used to be — won't work. But Brusaw suddenly has a reason why it will — actually, 2.2 million of them. Solar Roadways' crowdfunding campaign, which closed on Monday, raised $2.2 million — more than double what Brusaw was seeking — in just two months. The campaign, the most popular in Indiegogo's history, attracted more than 48,000 backers from all 50 states and 165 countries. "It's been humbling," Brusaw, 56, told Yahoo News. "Really, really humbling." The success can be attributed, in part, to a cheeky seven-minute video ("Solar FREAKIN' Roadways!") that has been viewed more than 16 million times on YouTube.
Many people, even fanatical advocates of solar power, are unaware quite how close we are to reaching a critical milestone in the industry. Within a fairly short space of time, solar generated electricity will be fully cost competitive with coal-powered electricity -- at least if the governments of the world’s two largest energy consuming nations have their way. Both the U.S. and China have a stated goal of reducing the cost of solar generated electricity to that level, and quickly. How they are going about it says a lot about how each economic system works. In the U.S., despite the complaints of some that a drift toward government control is taking place, private initiative and free markets still rule. The Department of Energy launched the SunShot initiative in 2011, with a stated goal of reducing the cost of solar power to be fully competitive with conventional energy sources by the end of this decade. The program funds grants, incentives and competitions to encourage private sector research that will improve the efficiency and lower the cost of solar energy. The Chinese, faced with what is in many ways a more urgent need to achieve the same thing, have taken a different approach. In a manner more in keeping with their history and current economic system, they are beating the problem over the head with piles of cash until the desired outcome is achieved. It looks, if this excellent Michael Sankowski piece at Monetary Realism is to be believed, as if they are getting mighty close.
Massachusetts Deval Patrick and U.S. Interior Secretary Sally Jewell announced plans for a new proposed offshore wind power area of more than 742,000 acres, or 1,160 square miles, which would make it about the size of Rhode Island (1,214 sq-miles). This new area, where space would be auctioned in 4 different leases, would nearly double the federal offshore acreage available for large wind energy projects. Secretary Jewell said that the government has learned from the Cape Wind offshore wind project in Nantucket Sound, which faced over a decade of opposition and lawsuits, and have picked a spot farther from the shore that should not be as contentious. "We put in zones that we believe have both high potential and lower conflict," Jewell said. "But it's going to actually get down to a specific construction plan on a specific site and (an environmental) analysis to determine what people want to do economically and what that impact is going to be.
SolarCity is already the largest installer of residential solar panels in the United States. Now the company is going a step further, buying up solar manufacturer Silevo and planning to build one of the world's biggest solar-panel factories in upstate New York. The immediate goal here is vertical integration. The company, which was co-founded by Tesla CEO Elon Musk, wants to handle all aspects of the solar supply chain, from design to manufacturing to sales to installation. It's basically the Apple model — only for solar panels. But SolarCity's ultimate aspiration is to drive down prices dramatically. In a call on Tuesday, Musk said that the aim was "to have solar power compete on an unsubsidized basis with fossil-fuel energy from the grid." (The company was also founded by brothers Lyndon and Peter Rive, who currently run it.) Is that doable? SolarCity has had success with its current business model — offering rooftop solar systems at no upfront cost to customers who make monthly payments spread out over many years. The company now handles 25 percent of all US residential solar installations — and is aiming for 1 million customers by 2018. This latest move means SolarCity will be able to produce its own panels for these systems and try to lower its costs even further.
A new report from NREL, the National Renewable Energy Laboratory, could help spur the development of more utility scale concentrating solar power plants with thermal energy storage features while boosting the market for solar cells, too. The report indicates that CSP/energy storage projects could add value to utility scale solar energy in California, and they would enable more solar cell development by creating additional grid flexibility. California’s ambitious renewable energy goal for 2020 also plays a key role, so keep in mind that the NREL added-value findings for thermal energy storage are transferable to only to other states with similar aspirations.
Residential Energy Generation and Storage Will Reach $71.6 Billion in Annual Revenue by 2023, Forecasts Navigant Research
Solar photovoltaic (PV) panels, which enable customers to generate some of their own electricity and sell unneeded power back to their utility, are the most visible form of the broad disruption caused by distributed energy resources (DER). The growing affordability of DER technologies is altering utilities’ traditional relationship with residential customers by giving customers greater control of their energy consumption. According to a new report from Navigant Research, worldwide revenue from all forms of residential distributed generation and energy storage will grow from $52.7 billion annually in 2014 to $71.6 billion in 2023. “Rooftop solar PV is just one of the technologies that are transforming the traditional residential power industry,” says Neil Strother, principal research analyst with Navigant Research. “Some of these technologies, such as residential combined heat and power, are in the early stages of market development, while solar panels are more mature. Nonetheless, these energy innovations and attractive financing mechanisms provide residential customers with new options.” One key driver for this sector, according to the report, is continuing advances in new technologies, such as more efficient energy storage systems (ESSs). These advances, along with government subsidies for ESSs, often in the form of feed-in tariffs, are enabling the combination of rooftop solar PV systems and residential energy storage in order to collect and store energy for use when sunlight is unavailable or there is a power outage.
Warren Buffett is ready to double his $15 billion investment in renewable energy, according to reports. Speaking at the Edison Electric Institute’s annual convention in Las Vegas Monday, Buffett described how he had briefly lost track of how much Berkshire Hathaway had invested in the sector and needed a reminder from a deputy. Buffett said he responded “there’s another $15 billion ready to go,” according to Bloomberg News. Buffett’s investments include wind farms in Iowa as well as solar farms in California and Arizona. Buffett also vowed to keep investing in utilities. The sector may not make you rich, but it will keep you rich, the legendary investor was quoted as saying in another report. Berkshire Hathaway’s MidAmerican Energy last year bought two co-located solar-power projects that combined are the largest solar project in the world. Last month, MidAmerican said it will supply Google Inc. facilities in Iowa with electricity from wind power.
A new windmill design loosely based on Archimedes’s screw principle, aims to change this, however. A Dutch startup aptly named The Archimedes has re-worked the concept of the windmill to move away from the traditional concept of using the pressure differential between the front and rear of the device to move the rotors. The Liam F1 Urban Wind Turbine, modeled after a Nautilus shell, measures about 1.5 meters wide and weighs 75 Kg — an ideal size for installation in a residential setting. The turbine is rated to achieve an efficiency “80 percent of the maximum that is theoretically feasible." According to the creators, the device is designed to provide enough electricity to power an apartment or small home. “The Liam F1 generates an average of 1,500 kilowatt-hours of energy [per year] at a wind-speed of 5 m/s [16.4 ft/s], which resembles half of the power consumption of a common household.” The Liam can even adjust to wind direction, which enables it to maximize power generation even with changing conditions. The Liam is priced at Eur 3,999 or about US$ 5,450 and will start retailing by July 1st. The Archimedes says it has sold 7,000 units in 14 countries so far. The company says it has undertaken field tests for efficiency and power generation “over 50 times,” in which it has achieved its rated output and efficiency.
Intersolar Europe, the world's largest exhibition for the solar industry and its partners, pays tribute to the solar industry's innovative strength for the seventh time. The ten most innovative companies were honored during an official ceremony that took place today at Intersolar Europe's Innovation Exchange.

Manufacturing solar panels can be a dirty business, from the mining of raw materials to the chemical-laced process of purifying silicon to the assembly of silicon wafers. Solar energy is a renewable source, of course, but it’s essential to examine the full supply chain to gauge its total environmental impact. One potential concern is the use, containment, and disposal of toxic chemicals. Another is the energy-efficiency of the manufacturing process and the source of the energy used. Researchers at Northwestern University and the U.S. Department of Energy’s Argonne National Laboratory recently examined the solar panel production process in different locations and published their findings in the July issue of the journal Solar Energy. “We estimated that a solar panel’s carbon footprint is about twice as high when made in China and used in Europe, compared to those locally made and used in Europe,” says Fengqi You, a co-author of the paper and an assistant professor of chemical and biological engineering at Northwestern. “While it might be an economically attractive option to move solar panel manufacturing from Europe to China, it is actually less sustainable from the life cycle energy and environmental perspective.” The primary differences, the researchers found, are the less stringent enforcement of environmental regulations in China coupled with the country’s more coal-dependent power sector. “It takes a lot of energy to extract and process solar-grade silicon,” says co-author Seth Darling. “And in China, that energy tends to come from dirtier and less efficient energy sources than it does in Europe.”
The Environmental Protection Agency on Monday released a draft rule to regulate carbon emissions from hundreds of fossil-fired power plants across the U.S., the cornerstone of President Barack Obama's climate-change agenda. The proposed rule mandates that power plants cut U.S. carbon-dioxide emissions 30% by 2030 from levels seen in 2005, an aggressive target that marks the first attempt at limiting such pollution. The carbon framework seeks to strike a balance between what environmentalists want—an ambitious overall target—with what the utility industry wants—flexibility, a long compliance timeline and an earlier base-year calculation from which to meet the goal. Carbon emissions have dropped since 2005, making the overall reduction smaller than it would have been if the EPA had used a more-recent year for a baseline.
U.S. Residential Solar PV Installations Exceeded Commercial Installations for the First Time in Q1 2014
Driven by strong year-over-year growth in the utility and residential markets, the United States installed 1,330 megawatts of solar photovoltaics (PV) in the first quarter of 2014. According to GTM Research and the Solar Energy Industry Association’s (SEIA) Q1 2014 U.S. Solar Market Insight Report , the U.S. installed 232 megawatts of residential PV, exceeding the non-residential (commercial) market’s 225 megawatts for the first time in the history of the report. Ongoing strength in the residential sector and volatility in the non-residential market spurred this historic milestone. Despite the dip in non-residential installations, GTM Research and SEIA expect the market to rebound and exceed the residential market in 2014 annual PV installations. In another significant development, Q1 2014 was the largest quarter ever for concentrating solar power (CSP) due to the completion of the 392 megawatt (AC) Ivanpah project and the Genesis Solar project’s second 125 megawatt (AC) phase. With a total of 857 megawatts expected to be completed by year’s end, 2014 is on pace to be the largest year for CSP in history. “Solar accounted for 74% of all new U.S. electric capacity installed in Q1 2014, further signaling the rapidly increasing role that solar is playing in the energy market,” said Shayle Kann, Senior Vice President at GTM Research. “Expect to see a resurgence in the non-residential market, combined with continued incremental residential growth, throughout the rest of this year.” Not to be outshone by the success of the residential sector, the utility PV market continued its dominance, growing 171% between Q1 2013 and Q1 2014. With 873 megawatts installed, it accounted for two-thirds of total installations during the quarter. Large-scale projects that were under contracts and negotiations between 2010 and 2012 are now becoming a reality.
In an almond orchard outside Turlock in the Central Valley, two large tanks hold water, minerals - and more importantly, energy. The tanks in Stanislaus County are part of a "flow battery" that stores energy from nearby solar panels. It's the largest battery of its kind in the world. And it could play a role in California's push to develop bigger and better ways to store large quantities of energy. This particular flow battery, unveiled to the public Thursday during a ceremony with state and federal officials, was built by EnerVault of Sunnyvale, part of the Bay Area's fast growing energy-storage industry. Like most of its competitors, EnerVault is young, founded in 2008, with about $30 million in venture funding to date. Some companies try to perfect the lithium-ion batteries found in laptops and electric cars. Others, including EnerVault and Primus Power of Hayward, specialize in flow batteries, which store energy in tanks of electrolytes. The fluid is then pumped through the battery's cells when power is needed. In contrast, the batteries found at a grocery store contain the electrolyte, cathode and anode all in one package. "Flow batteries are batteries turned inside out," said Jim Pape, EnerVault's chief executive officer. His company's flow batteries use iron and chromium, blended into the water inside its tanks. Both materials are safe to handle. (For those of you thinking "Erin Brockovich," EnerVault uses the kind of chromium found in multivitamins, not the infamous hexavalent chromium featured in the movie). Iron and chromium also have the benefit of being cheap.
Congressional inaction on key clean energy tax policies, coupled with attacks on state renewable energy programs, led to a dramatic decline in clean energy job announcements in the first quarter of this year, according to the latest report from the nonpartisan business group Environmental Entrepreneurs (E2). About 5,600 clean energy and clean transportation jobs were announced in the first three months of this year, down from 12,000 such jobs reported in the comparable period in 2013. A major geothermal project in Idaho accounted for the most clean energy jobs announced on the state level in the first quarter. Idaho was followed by more traditional clean energy leaders. The remaining states in the Top 10 were: Texas , California , Missouri , New York , Kansas , Arizona , Hawaii , New Mexico and Louisiana .. Despite adding thousands of new jobs to the economy, the dramatic drop in clean energy and clean transportation job announcements in the quarter is a clear reflection of mixed signals American businesses are getting from Capitol Hill and state capitals when it comes to policies such as the federal Production Tax Credit (PTC) and various state-level renewable energy standards (RES), according to E2.
