The research was done by studying different clusters of solar panel installations in California from January 2001 to December 2011. The researchers found that residents are much more likely to install solar panels if they are already installed in their zip code, and particularly if they are installed on their street.
“We looked at the influence that the number of cumulative adoptions — the number of people who already installed solar panels in a zip code — had on the probability there would be a new adoption in that zip code,” said Kenneth Gillingham, the study’s co-author and assistant professor of economics at the Yale School of Forestry & Environmental Studies. “Our approach controls for a variety of other possible explanations, including clustering of environmental preferences or marketing activity.”
The results were pretty significant, just 10 extra solar installations in a zip code made it 7.8% more likely that someone would install them themselves. And with just a 10% increase in the number of people within a zip code to have solar installations, there will be a 54% increase in the number of those going solar.
The study also clearly shows what led to the increase: visibility and word-of-mouth. “If my neighbor installs a solar panel and tells me he’s saving money and he’s really excited about it, it’s likely I’ll go ahead and do the same thing,” said Gillingham. “Then there are others who’ll install because they don’t want to be one-upped by their neighbors.”
The new research was just published in the journal Marketing Science.

Another goal Indonesia has is 10,000 MW of geothermal by 2025. If it achieves this one, up to 800,000 people could be employed by the creation and operation of the new plants.
Foreign companies are already playing a role in Indonesia’s geothermal energy. Mitsubishi Corporation is committed to acquiring a twenty percent share of the company that manages the largest geothermal facility in the country. British Petroleum has been given permission to explore 28 locations around the nation to research geothermal potential. The largest geothermal energy producer there is Chevron Corporation, and it said it welcomes the competition with BP, should it arise.
The largest Indonesian geothermal plant is Wayang Windu located in West Java. There are two units in operation with a capacity of 227 MW. By the middle of 2013, another 127 MW is planned to be added. It is already one of the largest geothermal plants in the world.
Indonesia is one of the top five geothermal energy countries on the planet. The United States is in the top position, with the Philippines in second.

Counting wind projects from 1999-2010 (based on data from LBNL’s excellent Wind Technologies Market report) the average size of an American wind project is 80 megawatts (MW). The size of projects has risen in the past decade, from about 50-60 MW, but largely because the average turbine size in US wind projects has nearly doubled to 1.79 MW in that time period.
Interestingly, the most economical wind projects are between 5 and 20 megawatts.

The expansion has been in the works for awhile now, so the signing is somewhat of a formality, but an important one. The expansion of the line will at least double its ridership, according to FTA Administrator Peter Rogoff.
Charlotte is the home of one of North Carolina’s largest universities, but because of its location, it has remained somewhat unintegrated with the rest of the city. There have been some improvements in recent years, but none like this.
The city is hoping (rightly) that the extension will go a long way to revitalize neighborhoods running along the new extension. "If the light rail's South Corridor is any predictor, it will.” Such lines have revitalized neighborhoods and stimulated economic growth in many other cities, as well.

What I’m writing here is not just a thought from my own head, though — it’s based on careful psychological research. Here’s an example of this “familiarity backfire effect” from one study:
“To test for this backfire effect, people were shown a flyer that debunked common myths about flu vaccines.1 Afterwards, they were asked to separate the myths from the facts. When asked immediately after reading the flyer, people successfully identified the myths. However, when queried 30 minutes after reading the flyer, some people actually scored worse after reading the flyer. The debunking reinforced the myths.”
And just give it a little thought — if you hear or read a myth repeatedly, but any explanations debunking the myth don’t fully sink in, down the road you might just recognize the statement/myth (that you had come across is it before) and assume it must therefore be true.
Going on, John Cook and Stephan Lewandowsky write:
“The driving force is the fact that familiarity increases the chances of accepting information as true. Immediately after reading the flyer, people remembered the details that debunked the myth and successfully identified the myths. As time passed, however, the memory of the details faded and all people remembered was the myth without the "tag" that identified it as false. This effect is particularly strong in older adults because their memories are more vulnerable to forgetting of details.”
Check Out the Debunking Handbook!
This is actually just one of several common mistakes commonly made by “mythbusters.” To my great frustration or disappointment, I see people making this mistake almost every day when debunking very harmful myths. So, I’m (re)sharing this point with you all (in case you do a bit of mythbusting in your spare time), and pointing you again to this great and free Debunking Handbook created by the folks over at Skeptical Science. Please, read it, read it carefully, and follow its advice!
Mythbusting without Stimulating the Familiarity Backfire Effect
Since the focus of this post was the familiarity backfire effect, I should probably share how to avoid this mistake. Here’s the conclusion from John and Stephan:
“How does one avoid causing the Familiarity Backfire Effect? Ideally, avoid mentioning the myth altogether while correcting it. When seeking to counter misinformation, the best approach is to focus on the facts you wish to communicate.”
“Not mentioning the myth is sometimes not a practical option. In this case, the emphasis of the debunking should be on the facts. The often-seen technique of headlining your debunking with the myth in big, bold letters is the last thing you want to do. Instead, communicate your core fact in the headline. Your debunking should begin with emphasis on the facts, not the myth. Your goal is to increase people's familiarity with the facts.”

Homes built to voluntary ENERGY STAR® specifications made up about 26% of all new homes constructed in the United States during 2011. Under the latest update of the specifications that went into effect earlier this year, ENERGY STAR homes consume at least 15% less energy than those built to the 2009 International Energy Conservation Code (IECC).
There is currently no national building energy code. States have adopted a variety of codes with different levels of stringency, mostly based on the IECC, a building energy code created by the International Code Council. Often the stringency of these state building codes and ENERGY STAR participation is correlated: all but one of the eight states lacking a statewide energy code have low ENERGY STAR participation, while Arizona’s strong utility support for energy-efficient construction has fostered a high penetration of ENERGY STAR qualified homes, even though there is no statewide code there.
A home can get ENERGY STAR certification in one of two ways: the prescriptive path or performance path. Both paths have program requirements common to all qualifying homes across the nation. The prescriptive path incorporates predefined improvements based on a home’s IECC climate zone, while the performance path uses home energy modeling to account for savings based on a more flexible use of energy savings measures. A certified Residential Energy Services Network (RESNET) home energy rater verifies that specific requirements of the guidelines are met.

The type of charger the bus is equipped with is an induction charger. Induction chargers operate by using inductors to generate an electromagnetic field which another receptive inductor in the bus uses to generate electricity.
This bus is can be charged by plugging in overnight or via wireless charging.
These chargers are not the long-range type (such as microwave power transmitters) which transmit power without wires to devices hundreds of feet away, but it is a convenient short-range type that is set up in the bus lane so that the bus automatically starts charging as soon as it drives over it at a stop.
Buses Can Benefit More from Wireless Induction Chargers than Cars
Electric cars, unlike buses, don’t tend to have completely predictable, fixed schedules. So it’s not surprising that on-road wireless charging for buses is popping up first, but roads may soon be equipped with induction chargers that could charge cars at stoplights, as well.

Yep, it’s all about the Benjamins… or
“The cost of producing solar panels is constantly dropping – largely due to the arrival of major players out of China, so the barrier to entry is being lowered all the time,” a post about the Australian commercial solar shift on sister site The Inspired Economist notes. “In fact, we've seen costs of solar systems drop by around 50% from 2011 – 2012, meaning the once high capital costs associated with installing a system are diminishing – fast. By moving your business to a solar energy source, you're in effect hedging your bets against rising electricity prices.”
Yep, we just wrote about the quick, nonstop drop in solar panel prices (for the 100th time) the other day.

"With gas prices this high in California, this is the perfect opportunity to spell out the extremely low operating costs electric vehicles have to consumers," said Thomas Hausch, CODA senior vice president of sales, marketing and aftersales. "When comparing vehicles, the total cost of ownership (TCO) is critical to consider, along with the purchase price, as it provides a comprehensive view of the bottom line. Once consumers review these factors and in turn, discover the benefits of an EV – including significantly lower maintenance costs, avoiding high gas prices completely, low electricity prices, access to the carpool lane, various tax incentives and more – going electric in today's climate makes a lot of sense. It makes you think: When has cutting edge technology been more affordable than the 'old school' version it replaces soon after its introduction?"
The deal makes a very clear contrast between the very low ‘fuel’ costs of EVs and the continually rising fuel costs of fossil-fuel-powered cars. Driving a CODA for 10,000 miles only costs you about $552 in electricity, compared to the $1500-$2000 you’d spend for gasoline or diesel.
The rebate will be for the new 2012 CODA, the first completely electric five-passenger, compact sedan, possessing full rear seating and large trunk space. It will have a range of at least 88 miles per charge, and up to 125 miles. And the recharge speed looks to be pretty good, at about six hours for a full charge.
With all the tax credits taken into account, the total price in California works out to about $27,250.
CODA's 10,000 free miles promotion is a point-of-sale instant rebate of $552 and is available through CODA dealers through October 31, 2012. California consumers can contact a CODA dealer for test drives and more information: CODA Los Angeles; CODA of Silicon Valley; Fladeboe CODA in Irvine, Calif.; and Marvin K. Brown CODA San Diego.

The researchers used holographic lithography to create the material, recreating the wings’ reflective properties with a “3D cross-linked pattern in a kind of material called photoresist.” Afterwards a solvent is then used, washing away all the photoresist untouched by the laser. This creates a three dimensional structure that is able to affect the light that hits it. The researchers then use a ‘poorer’ solvent to roughen up the surface, resulting in the ‘fuzzy’ water-resistant texture.
The primary goal of the researchers who worked on this was to create ‘hydrophobic coatings’ that will help to improve solar panels. These coatings will allow solar panels to be more efficient by keeping them cleaner and drier.
“Specifically, we’re interested in putting this kind of material on the outside of buildings,” Yang said. “The structural colour we can produce is bright and highly decorative.”
“The butterfly building would be connected to a chip that would let its owner change its colours and transparency at will. Because the material is water-resistant, it wouldn’t need to be cleaned as often.”
The current estimate is that the prototype will be ready in June.

This is the fourth contract Siemens has undertaken in the country, and this latest project will see the Balabanli plant achieve a capacity of 50 megawatts, enough to supply approximately 43,000 Turkish households with clean electricity.
“The Turkish wind energy market is attractive for Siemens and we expect further growth in the future,” said Felix Ferlemann, CEO of the Wind Power Division of Siemens Energy. “The fourth wind power order from Turkey shows that we are not only doing well in the offshore sector, but that we are also successful in onshore wind energy.”
Siemens will be providing 22 wind turbines, each with a capacity of 2.3 megawatts and a rotor diameter of 108 metres. Siemens will also be providing a long-term service agreement which will see the company guaranteeing availability and extended warranty on major components over the entire term of the agreement.

The program, Renewable Energy and Rural Electricity Access (REAP), was launched by the Mongolian government and supported by the World Bank and the Government of the Netherlands.
Over half a million men, women, and children now have access to electricity wherever they travel as they follow their herds of yak, cattle, sheep, goats, and camels around the 1.5 million square kilometres they call home.
“We are proud to be part of this effort, which means 500,000 people, or half the rural population of Mongolia, have electricity through portable and affordable solar home systems," said Pamela Cox, World Bank Regional Vice President for East Asia and Pacific in her first visit to the country.
"Now, children can study at night, families can watch TV and recharge cell phones, enabling them to connect to the world while maintaining their nomadic lifestyles. This is one of many innovative ideas that we are putting to work on the ground to make growth more inclusive."
Did they want electricity though?
These Mongolian herders have been living in this fashion for century upon century, and the first question that came to my mind upon reading this story was ‘Who wanted the herders to have electricity?’ Was it the government or the herders themselves?
That’s the only quote provided by the World Bank, though they do go on to add that herder families are now able to use television weather reports to help manage their livestock and use mobile phones to determine market prices for wool and cashmere. Economically sensible, yes, but hardly a rousing vote of confidence on the part of the herders themselves.
The World Bank press release cosily reports that “families can now relax and spend time together at night under electric lights. Children can learn by reading and from watching television.” Seems to me that families had been relaxing together and learning quite well on their own for several hundred years without the intervention of electricity.
Nevertheless, the availability of such technology for communities such as Mongolian herders is a boon for not only the industry, but those communities around the world who may in actual fact both desire and require electricity. One can only hope that the World Bank and governments like the Netherlands are looking to other countries more impoverished with similar intentions in mind.

About 88 companies are predicted to shutter PV factories, mainly in the United States, Europe, and Canada. The cost of solar panels and their manufacture has dropped so much it is simply too costly to produce them competitively in certain parts of the world. The number of companies affected by the fast-changing market conditions is huge, and very sad for the demise of their once promising ventures.
“Manufacturing costs for firms in Europe, the U.S. and Japan are currently over 80 cents per watt. The cost for their Chinese competitors is between 58 cents and 68 cents per watt. The writing is on the wall: these companies will either take what they can get via acquisition or they will bow out,” said the report’s author, Shyam Mehta, Senior Analyst at GTM.
Even the Chinese manufacturers are vulnerable, though. About 54 of them are anticipated to go under as well. Some of these companies have been called ‘solar zombies’ because they have received government support while not functioning competitively on their own.
Much political hay was made with the Solyndra demise and one can only imagine a huge loss of various solar panel companies might be similarly exploited. It is difficult to be sympathetic to failed government-supported ventures, but there are also gigantic and ongoing subsidies for fossil fuels, so I think the continued support for renewable energy is completely reasonable and justifiable.

The 1-megawatt (MW) battery went live late last week and once fully operational will store solar energy produced in the area, help smooth out peak demand, and limit regional power outages.
It may not look like much more than a simple 45-foot-long trailer, but the Battery Energy Storage System (BESS) could be the next step in community-scale energy storage. At full capacity, the nanotech polymer lithium ion battery can supply the electricity demand of 400 homes for about an hour.
The system's performance results will be independently tested and analyzed before it goes fully online in order to determine environmental, economic, and reliability impacts.
While the BESS design and output is impressive by itself, its impact on Kansas City could be even more significant. As the anchor of Kansas City Power and Light Company's (KCP&L) $48 million dollar SmartGrid Innovation Park, the battery ties together a solar array, electric vehicle charging station, regional grid monitoring station, and urban park. It's also open to the public and provides programs to educate consumers about their energy use.
In turn, the Innovation Park is at the heart of the city's Green Impact Zone, an effort to transform a 150-square block area of Kansas City. The zone has suffered severe economic decline and an estimated 50 percent unemployment rate. A combination of weatherization programs, green collar job training programs, renewable energy and smart grid investments, and overall sustainability strategy aims to transform the neighborhood into a green economic zone.

The timber tower support structure is a wooden hollow column with a multi-sided cross-section. Hexagonal, octagonal, or dodecagonal cross-sections are used. The timber used to make the wooden pieces are sourced from ecologically and economically responsible forestry practices. The wood has a PEFC certificate, which is a standard in Europe for socially responsible business.
One of the main advantages of using wood for wind power towers is cost. Steel can by very expensive, but locally sourced timber typically is much cheaper. Another advantage is transportation of the tower materials and pieces to challenging locations. Wood materials are easier to carry via large trucks than tubular steel sections.
Timber Towers are guaranteed to have a minimum life cycle of twenty years. Once a tower has exhausted its usefulness, the materials can be recycled.
