Will Solar Energy Plummet if the Investment Tax Credit Fades Away?
Wall Street Journal: Many supporters say the abrupt end date of the 30% credit represents a “cliff” for the industry. Without the current incentive, they argue, installation of solar-power systems will plummet, and thousands of jobs in the industry will be lost as a result.
Others, however, argue that the cliff isn’t as steep as it appears, and that solar will continue to grow even without the 30% credit—albeit not as quickly as before.
Amit Ronen, director of the GW Solar Institute and a professor at the Trachtenberg School of Public Policy at George Washington University, argues that the end of the 30% credit will send solar off a cliff. John Farrell, director of the Democratic Energy initiative at the Institute for Local Self-Reliance, says the impact of the tax credit is overstated and the solar market will continue to rise.

Large solar projects can be done responsibly
BY SHANNON EDDY, Special to The Bee: As the seventh-largest economy in the world and a clean-energy leader, California plays a key role in shaping the global response to climate change. The benefits of our leadership will be on the world stage later this month during the international climate talks in Paris.
Over several decades, California has successfully advanced the development of renewable energy resources. As a result, the state boasts the highest concentration of solar projects in the nation, including several of the world’s largest. Large-scale solar power plants are enabling California to meet the goals of reducing carbon emissions to 1990 levels by 2020 and generating 50 percent of its electricity from renewable sources by 2030.
Eleakis & Elder Photography
As with any fast-growing, successful industry, it’s essential to ask questions about unintended consequences. We agree it is important to evaluate how the environmental benefits of large-scale solar – carbon reduction, reduced water use and improved local air quality – compare to any negative consequences for people and the environment.

Honoring Our Veterans through Jobs in Solar Energy
From the Department of Energy - On Veterans Day, we honor the more than 21 million living American veterans. Here at the Department of Energy, we are honored to have the opportunity to express our gratitude to veterans of previous wars, welcome home those who have recently served, and thank the future veterans who still stand sentry for our nation.
The Department of Energy is working hard to open doors to career opportunities for veterans in the dynamic solar industry, which now employs more than 174,000 people -- more than auto and light truck manufacturing -- and has been adding jobs 20 times faster than the wider economy. Already, we are proud that veterans make up more than 10 percent of the solar industry workforce. Cont'd...
Say Goodbye to Solar Power Subsidies
Mark Chediak & Chris Martin for Bloomberg Businessweek: In 2016 the U.S. will learn if renewable energy can survive without government support. The most significant tax credit for solar power will expire at the end of 2016, and the biggest one for wind already has. These federal subsidies have provided wind and solar developers with as much as $24 billion from 2008 to 2014, according to Bloomberg New Energy Finance. That’s led to a 12-fold increase in installed capacity over the past decade, helping lower costs at least 10 percent each year.
Combined, wind and solar still generate less than 5 percent of electricity in the U.S. The subsidy cuts come as both industries face stiffer competition from ultracheap coal and natural gas. An NYSE Bloomberg global index of solar stocks, including those of big developers SunEdison and First Solar, has fallen about 35 percent since June. A comparable wind index is down 20 percent.

Thin film perovskite solar cell passes the efficiency test
Matthew Gunther for Chemistry World: Perovskite solar cells may one day rival silicon-based technologies, but their performance outside the laboratory has been a constant source of contention in the past year. Now, an international team of scientists has manufactured the first thin film perovskite solar cell with a reported efficiency that has beenofficially recognised by an accredited national test laboratory.1
Since their development in 2012, the performance of light-harvesting metal–organo halide structures has seemingly improved at a staggering rate, with their efficiency increasing by six percentage points in just two years – the same increase took multi-crystalline solar cells over two decades.
But their stability has been brought into question, with some international test centres taking issue with perovskite solar cells that are so unstable that they may degrade spontaneously in air, making it hard for them to assess their performance.
It’s a state of affairs that Michael Grätzel from the Ecole Polytechnique Fédérale de Lausanne in Switzerland has had trouble dealing with. ‘Conspicuously, you could see that from the very beginning there was very scarce information on the stability of these devices,’ comments Grätzel. ‘I have raised that issue many times – one would think that now everybody does stability work after this alarm was sounded, but not so.'

Texas hits new wind power milestone on Thursday
By Jordan Blum for Fuel Fix: The Texas electric grid hit a new record for wind power use early Thursday, as the state continues dominating the rest of the nation in wind farm growth.
At 12:30 am Thursday, the main Texas grid operator reported that nearly 37 percent of demand was met with wind power. The Electricity Reliability Council of Texas, which manages nearly 90 percent of the state’s electric needs, said it used 12,237.6 megawatts of wind power at the time. That bested a previous record set on Sept. 13 of 11,467 megawatts.
A megawatt powers about 500 typical Texas residences during periods of normal demand.
The new record came the same day as the American Wind Energy Association reported Texas accounted for nearly half of the nation’s wind power growth in the third quarter of the year. Texas added 771 megawatts of wind generation in the third quarter and, nationwide, about 1,600 megawatts were put online. Texas now has about 16,400 megawatts of wind power, according to the AWEA, which is about 10,000 megawatts more than the second and third windiest states, California and Iowa. Cont'd...
UK solar power industry proposes emergency plan to save renewables
Mark Tran for The Guardian: The solar power industry has proposed an emergency plan to rescue renewables, which it says would add just £1 to consumer bills by 2019, on top of the £9 a year that clean technology subsidies cost bill payers.
The scheme is a response to government plans to cut subsidies for rooftop solar panel installations by 87% from 1 January. The Solar Trade Association (STA) has warned the move could cost up to 27,000 jobs and waste public money already spent on supporting the technology.
Solar companies are already going bust as a result of the changes, with an estimated 1,000 jobs lost so far. On Friday, a company backed by the billionaire inventor Elon Musk pulled out of the UK, blaming the government for not supporting the technology.
Zep Solar UK, which is owned by SolarCity where the Tesla boss is chairman, was the fourth UK solar business to close in a fortnight. SolarCity blamed cuts to solar subsidies announced by the Department of Energy and Climate Change (DECC) in the summer.
The STA plan would include higher initial tariffs for subsidies to make investing in the technology viable, with reductions set out to allow the government to control costs and give the industry certainty. The plan would ensure that families, farmers, housing associations and community groups could continue to be involved in the move towards low-carbon power and give them more control over their energy, the STA argues.

How a Manmade Tidal Lagoon Could Change the Future of Clean Energy
FEARGUS O'SULLIVAN for CityLab: Just outside the Welsh city of Swansea, the U.K. is planning one of the most innovative power plants ever constructed. It’s not the plant’s size that is striking, though it could ultimately provide power to 155,000 homes for 120 years. It’s the source of its power that breaks ground: tides channeled into an artificially constructed lagoon.
Granted full planning permission this June, the Swansea Bay Tidal Lagoon will be the world’s first ever plant to generate electricity using this method. Should it prove successful, the plant’s template could be adopted worldwide as a way of generating green power while simultaneously providing sea wall protection to coastal communities. Cont'd...
UK - It could be lights out for solar power under this government
Terry Macalister for The Guardian: Ministers rightly wring their hands over the 2,200 jobs being lost at the 98-year-old Redcar steelworks hit by low-cost Chinese competition. But they seem deaf to warnings of 27,000 jobs being potentially lost in a brand-new industry now facing crisis due to their own clumsy cuts.
Almost 1,000 redundancies have already been made by the solar panel installersMark Group and Climate Energy. No one in the industry believes this will be the end of the sad story.
The latest flashpoint for “green” developers is the government plan to slash the feed-in tariff – which subsidises people installing solar panels on their home – by almost 90%. Meanwhile, an energy-efficiency regime has been scrapped with only a vague promise of a future replacement.
If these were isolated examples, then companies might be willing to hang on in the hope of better things to come. But they are the latest in a series of cuts not just to solar but also to onshore wind, and come at a time when it seems maximum effort is being expended on removing roadblocks to shale-gas frackingand nuclear power.

Cloaking Principle Could Boost Solar Cell Performance
Invisibility cloaking may be a long way from reality, but the principle could help improve the performance of solar cells in the near term.
In a series of simulations, researchers at the Karlsruhe Institute of Technology have demonstrated how cloaks made of metamaterials or freeform surfaces could eliminate shadows cast by energy-harvesting components onto the active surfaces of solar cells.
Contact fingers, which extract electric current, cover up to one-tenth of the surface area of a solar cell. By guiding light around these features, more of the sun's energy could be captured by the solar cell.
"Our model experiments have shown that the cloak layer makes the contact fingers nearly completely invisible," said doctoral student Martin Schumann. Cont'd...
SolarCity claims highest efficiency solar panel
Tristan Edist for the Business Spectator: SolarCity, the largest retailer of solar systems in the US (over 30% market share) and partly owned by Tesla’s Elon Musk, has announced it will produce the most efficient solar module available on the market at 22.04% conversion efficiency. SolarCity is claiming it has therefore managed to pip SunPower who have been the longstanding holder of the most efficient conventional silicon solar module on the market.
However in a subsequent discussion with Greentech Media, Peter Rive’s Chief Technology Officer conceded the majority of the panels coming off its pilot 100MW manufacturing line were hitting 21.8%. In 2017 the company will be then moving production to a new 1 gigawatt per annum capacity plant in Buffalo which can sometimes encounter challenges with achieving stable quality levels during production start-up.
SunPower claims 21.5% efficiency for its X-Series panel although often manufacturers will have some variance in performance of panels and make claims based on conservative estimates of performance. Greentech Media quotes an anonymous Sunpower source saying that 22% efficient panels are already coming off its production lines. In addition the company is targeting achieving 23% conversion efficiency from panels it will manufacture from its fifth fabrication line, scheduled for start-up in 2017.

Renewable Energy Surpasses Coal in the UK
Written by Keith Kohl for Energy & Capital: For the first time ever, more energy in the UK was supplied by renewable sources than coal. For an entire quarter. Wind, solar, and bioenergy checked in at 25% of the energy supplied.
All of this was possible due to the fact that more wind turbines and solar panels were installed, which must be a good amount if you want to compare it to the same period last year, for which these energy options only accounted for 16.4% of electricity.
Recently, the UK has been working to close aging coal and nuclear power plants.
Of course, this will lead to its own issues...
[Solar Panels] Conservative ministers collectively believe that the subsidies given to renewable energy were too numerous, going so far as to suggest plans for an 87% reduction of solar power, and to cut support for onshore wind farms.
With that kind of spending cut, it's not surprising to hear that industry execs believe these actions would unjustly put an end to renewable energy just as it was gaining traction. Cont'd...
Can the U.S. Jump-Start Offshore Wind Power?
By Camille von Kaenel and ClimateWire: The Department of Energy has awarded around a half-million dollars to New York, Maine, Rhode Island and Massachusetts state organizations to cooperate on scaling up the offshore wind industry in the region. Under the leadership of the New York State Energy Research and Development Authority (NYSERDA), the group will lay out a collaborative road map by the end of the year on how to build up the new industry. The project largely aims to reduce the cost of offshore wind projects, which has been a barrier to development, and establish a regional supply chain. Industry and state representatives learned about the federal grant at the first-ever offshore wind summit hosted by the White House yesterday. Offshore wind has struggled to take off in the United States. Europe, meanwhile, has more than 80 offshore wind farms with more than 10,000 megawatts of capacity. The White House summit marks a renewed effort to get the industry going in the United States, said various attendees. Cont'd...
Researchers develop cool way to improve solar cell efficiency
By Kelly Hodgkins for Digital Trends: A team of engineers from Stanford University have invented a cool way to improve the performance of solar panel arrays. A new material that the team produced literally will lower the temperature of solar cells even while they are operating in full-strength sunlight. As the solar cells cool, their efficiency will rise, leading to significant gains in the amount of energy harvested from the sun.
Solar panel technology has improved by leaps and bounds, but the technology has a flaw that limits the efficiency of the system. The panels must face the sun to operate, but the heat from this exposure diminishes their ability to convert light into energy. The hotter they get, the less efficient they become. This issue has perplexed the industry for years, but the Stanford team may have discovered a material that can help dissipate this excess heat without affecting the operation of the solar array.
The solution, proposed by Stanford electrical engineering professor Shanhui Fan, research associate Aaswath P. Raman, and doctoral candidate Linxiao Zhu, uses a material that is able to capture and emit thermal radiation (heat) away from the solar call. While deterring heat buildup, the thin, patterned silica material does not block sunlight, allowing the photons to enter the solar panel where they are converted to energy. It’s a win-win situation, allowing the free flow of sunlight and the removal of excess heat from the system. Cont'd...
El Niño Buffers U.S. Wind Power Dreams
Tim Maverick for Wall Street Daily: The National Oceanic and Atmospheric Administration (NOAA) made it official last week. The current El Niño is classified as a strong event.
An El Niño falls into the “strong” category if weekly sea surface temperatures depart from the average by more than two degrees Celsius.
In fact, this El Niño has nudged ahead of the 1997 El Niño as the strongest in the modern era!
Meteorologists believe this occurrence is actually the most potent since 1948. And it’s expected to persist through winter and into spring.
Every El Niño’s effects are different. At the moment, this one is having a surprisingly negative effect on the wind power industryin the United States.
You see, this occurrence of El Niño has produced the weakest winds across the United States in 40 years. Forecasters say this situation will continue and may even worsen through the spring of 2016. Cont'd...
