The Secret to Solar Power

By JEFF HIMMELMAN

Most mornings, Danny Kennedy hops on a bike with orange saddlebags and rides half an hour from his home to Oakland’s Jack London Square. He makes for quite a picture cruising down Telegraph Avenue, decked out as he often is in an orange helmet, orange jacket and orange leather Adidas shoes. When he arrives at his office, he often makes his rounds on an orange indoor bike. (He’s not joking around with the orange thing.) Though Kennedy was once a young environmental activist documenting the horrors of the oil and mining industries, he’s now a 41-year-old company man. The orange that he wears daily — which extends even to the checks on his shirts, and which drives his wife crazy — is the brand color for his rapidly growing residential solar company, Sungevity, whose revenues grew by a factor of eight in 2010 and doubled again in 2011, and whose employees have grown to 260 from 3 since the company’s inception five years ago.

Given that growth, it’s somewhat surprising to learn that Kennedy and Sungevity aren’t taken very seriously by their larger competitors. Kennedy’s activist past and his willingness to wear his commitment to the solar industry quite literally on his sleeve are viewed by some as a liability in an industry desperate to demonstrate its seriousness. Thanks to increased Chinese production of photovoltaic panels, innovative financing techniques, investment from large institutional investors and a patchwork of semi-effective public-policy efforts, residential solar power has never been more affordable. But even with pricing that requires no initial capital outlay from consumers and guarantees lifetime savings — and even occasional opportunities to make money, by selling power back to the grid — Americans still aren’t buying into solar in significant numbers.

Two factors have hurt the industry’s growth. The first is abstract and well ingrained in the American psyche: the negative association of “green” technologies with inefficiency and idealistic, hippie-fueled impracticality. The second is concrete and recent: the sleek, vacant headquarters of Solyndra, the infamous federally subsidized solar-panel manufacturer that went bankrupt in 2011. The glassy campus sits just off the Nimitz Freeway, visible to commuters between San Francisco and Silicon Valley as they battle rush-hour traffic each morning, surreptitiously checking their phones.

Though the failure of Solyndra has dominated the political and social discourse around solar power, the reality of the industry — as evidenced by the enormous investments that companies like Google and Bank of America are making in residential solar power — is that it has rapidly become a smart, practical and profitable investment. Despite a lack of widespread acceptance, the market is growing and the competition is getting tight.

Where Kennedy will ultimately fit into all of this remains to be seen. He told me: “We don’t need missionaries anymore. We need mercenaries.” As the industry grows, big investments don’t necessarily flow toward the people with the deepest environmentalist roots. No matter how much orange Kennedy wears or how dedicated to corporate branding he appears to be, his bleeding heart still shows through. Missionary, mercenary: can he — can anyone — be both?

New Energy Efficiency Standards for Residential Clothes Washers and Dishwashers to Save Consumers Billions on Energy Bills

Press release from DOE:


New Energy Efficiency Standards for Residential Clothes Washers and Dishwashers to Save Consumers Billions on Energy Bills

May 16, 2012

WASHINGTON – As part of the Obama Administration’s focus on taking sensible steps to save families money while also reducing energy consumption,  the Department of Energy today announced common-sense energy efficiency standards for residential clothes washers and dishwashers that will save consumers $20 billion in energy and water costs. The new standards for both clothes washers and dishwashers were informed by important feedback from manufacturers, consumer groups and environmental advocates, producing significant savings while retaining consumer choice. The clothes washers standard announced today will save households approximately $350 over the lifetime of the appliance, while offering consumers a variety of more efficient machine choices, and as a result of the standards for dishwashers, home dishwashers will use approximately 15 percent less energy and more than 20 percent less water, directly providing consumers with savings on monthly bills.

Today’s announcement is only the most recent in a series of common-sense efficiency standards made by the Obama Administration that have covered nearly 40 different products, and will together save consumers nearly $350 billion on their energy bills through 2030.

“Working with consumer, industry and environmental groups to develop common-sense energy-saving appliance standards is an important part of the Obama Administration’s all-of-the-above approach to American energy and the Energy Department’s efforts to reduce energy costs for consumers,” said Secretary Chu. “Collectively, these energy efficiency standards for everyday appliances have saved American families hundreds of billions of dollars and offered consumers more efficient, less costly appliances without sacrificing performance.”

“DOE’s implementation of these new standards reflects the consensus agreement reached by stakeholders. It will result in tremendous energy savings for the consumer while preserving product choice and minimizing manufacturer impact. The home appliance industry is proud of its long history of energy efficiency advancements benefiting consumers and applauds DOE for working with stakeholders to increase energy efficiency,” said Joseph McGuire, President of the Association of Home Appliance Manufacturers.
“Clothes washer and dishwasher energy efficiency has improved dramatically over the past two decades while also improving clothes washing performance and maintaining dish washing performance,” said Steve Nadel, Executive Director of the American Council for an Energy-Efficient Economy.  “These improvements have been driven by a combination of manufacturer and utility efforts, Energy Star, federal tax incentives and minimum efficiency standards.  We support the new DOE minimum efficiency standards which will raise the floor, helping to spur further efficiency improvements.

The new standards – developed in partnership with companies like Whirlpool, General Electric and LG Electronics, industry advocates, national environmental organizations, consumer groups and other stakeholders – build on previous minimum energy efficiency requirements for clothes washers and dishwashers and go into effect starting in 2015 and 2013, respectively.

Today, clothes washers and dishwashers account for approximately 3 percent of residential energy use and more than 20 percent of indoor water use in homes across the country.  The new standards for clothes washers will reduce the energy consumption of front-loading clothes washers by 15 percent and reduce water consumption by 35 percent, while top-loading washers will save 33 percent on energy and 19 percent on water use.

As companies look for ways to further boost the efficiency of their products,  companies will continue to undertake additional research and development, partner with entrepreneurs working on new efficiency technologies and invest in manufacturing innovations that will help drive better, more efficient appliances and broader job creation across the economy. For example, according to a 2011 trade report, standards laws signed by President Reagan and both Presidents Bush and DOE rulemakings generated approximately 340,000 jobs in 2010 alone.

The standards announced today are part of the Obama Administration’s broader all-of-the-above approach to American energy and the Department of Energy’s efforts to help families save money by saving energy.  Other energy and cost-saving standards adopted under the Obama Administration include:
  • March 2009 - 14 consumer and commercial products with standards prescribed in the Energy Independence and Security Act of 2007 (EISA 2007), including dishwashers, general service incandescent lamps and residential clothes washers
  • April 2009 - Microwaves, kitchen ranges and ovens
  • July 2009 - General service fluorescent lamps and incandescent reflector lamps
  • July 2009 - Commercial heating, air-conditioning and water-heating equipment
  • August 2009 - Beverage vending machines
  • December 2009 - Commercial clothes washers
  • February 2010 - Small electric motors
  • March 2010 - Residential water heaters, direct heating equipment and pool heaters
  • April 2011 - Residential clothes dryers and room air conditioners
  • June 2011 - Residential furnaces and residential central air conditioners and heat pumps
  • September 2011 - Residential refrigerators, freezers, and refrigerator-freezers
  • October 2011 - Fluorescent lamp ballasts
  • November 2011 - Direct heating equipment
  • May 2012 - Residential clothes washers
  • May 2012 – Residential dishwashers

Lease Option Increases Rooftop Solar's Appeal, Study Says

From the U.S. Dept. of Energy's National Renewable Energy Laboratory (NREL):

Lease Option Increases Rooftop Solar’s Appeal, Study Says

Low Down Payment, Immediate Savings, Lure a New, Less Affluent Demographic


Friday, January 20, 2012


Rooftop solar panels are attracting a new demographic of customers who are choosing to lease rather than buy, and enjoying the low upfront costs and immediate savings.
The new third-party-lease business model lets homeowners save money the very first month, rather than breaking even a decade later after an initial investment of $10,000 or $20,000.

Analysts with the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) found that the solar lease models are surging in southern California. And they're being adopted in less affluent neighborhoods that had few customer-owned systems.
The NREL study, "The Transformation of Southern California's Residential Photovoltaics Market through Third-Party Ownership," is in the current edition of the journal Energy Policy.

The study indicated an attraction for third-party leasing in neighborhoods with less affluence than those most likely to go for the customer-owned option.
It found a positive correlation between customers outright buying solar energy systems and customers living in neighborhoods where the average household income was $150,000 or more.

But with third-party-leased photovoltaic (PV) panels, that positive correlation appeared in neighborhoods where the average household income was just $100,000 or more.
If what's true in southern California proves true for the nation, it means that rooftop solar power could prove tempting for an additional 13 million Americans who live in households that earn between $100,000 and $150,000 per year.

"What is so interesting about the southern California data is that the strong decrease in PV prices – from lower retail costs and stronger federal incentives – didn't pick up a new demographic. But the new business model – leasing – did pick up a new customer demographic," NREL's Easan Drury, the lead author of the report, said.

Repackaging the value of photovoltaics as a simple savings on the monthly bill is an attractive alternative to the pitch that it will pay for itself in a decade, he said. "If someone comes up to you and says you can make money next month and forever, that totally changes how people see the value of solar."

Among Drury's other findings:
  • Third-party leasing usually eliminates the need for home-equity-style financing and, thus, the need for significant equity in the home. Without the hurdle of financing, more people can adopt solar, Drury said. 
  • Along with the lower income threshold, Drury found a surge in solar leasing in neighborhoods with younger families.
  • In the Los Angeles and Orange county markets, customer-owned PV was five times more prevalent than third-party owned in 2009. In 2010, the ratio had dropped to 2 to 1. And for the first quarter of 2011, the ratio was almost even.
Homeowners can put as little as $3,000 down and see an immediate drop in their electricity costs,  albeit that first year the drop may be just a couple dollars a month.
The real benefits come over the next two decades, when the $40 or $50 per month they're paying to lease the solar panels stays constant, while, presumably, the cost of electricity goes up. Third-party companies are touting potential customer savings of $10,000 to $15,000 over two decades.
