Spurred by some blend of concern over global warming, renewable energy targets and generous rebates, demand for solar in California is soaring. Responding to this challenge, California companies and cities have responded with innovative ideas — be it solar maps, power purchase agreements, installations paid for by property tax assessments and customer leases — that aim to make solar more affordable.

Add satellite imagery and Web 2.0 technologies to the list.

Berkeley-based start-up Sungevity wants to streamline the process of going solar and make it cheaper and easier for the average homeowner. The company uses Microsoft’s Virtual Earth satellite imaging service and proprietary software to give users a quick online quote of the best solar power systems for their homes, obviating the need for multiple visits by a crew for site assessment.

According to Sungevity, the company’s remote appraisal system can save a customer up to 10% over other solar companies because fewer site visits are needed. Once a potential customer enters a home address online, Sungevity e-mails back a suggested set-up among five solar-system options — ranging in cost from $7,500 to $38,500, including installation — and information about the financial returns for the customer. After the customer makes a selection, the system is delivered via UPS and a certified technician comes to install the unit.

Founder Danny Kennedy told Greentech Media he wants to see solar uptake through the middle class on a large scale. “The Internet is going to be a key channel to getting to customers and making it easy and low cost,” he added.

Verde Energy is another solar company that recognizes the potential of the Internet to speed solar adoption. Verde provides a bidding service for renewable energy installations using Google Earth and a survey its customers fill out online to gather information for projects that contractors then bid on, although it still requires an onsite consultation afterward.

Former Maryland Governor Parris Glendening spoke at the EcoCity World Summit 2008 about reshaping cities, making them more compact and pedestrian-friendly, and less dependent on oil. A Prius in every garage won’t be enough. “Better cars cannot make better cities,” he declared early in his talk.

Glendening is the founder and president of the Smart Growth Leadership Institute, which is dedicated to helping state and local elected, civic and business leaders design and implement effective land use strategies to successfully leverage coming growth.

A focus of Glendening’s presentation was the U.S. Green Building Council’s impending LEED for Neighborhood Development designation. Now in the pilot phase and set to launch in 2009, LEED for Neighborhood Development will not only consider a building’s energy and water efficiency and use of materials, but the collective ecological impact of the development within a community. After all, a building rated green for its efficient use of electricity may not be so green if it’s located far from transit and the city center.

The takeaway from Glendening’s talk is that if we rebuild our cities with high density in mind we’ll have to worry far less about the efficiency of our cars and can focus more squarely on the bigger help in our fight against global warming, which is improving the efficiency of our buildings.

This second installment in our series of posts on the Ecocity World Summit 2008 features Brent Toderian, the director of planning for the City of Vancouver, British Columbia. Toderian spoke about a new city-wide initiative called “EcoDensity,” which is based on the premise that strategically located, sustainably designed density can reduce a city’s ecological footprint, and that, done well, “density is our friend.”

Vancouver, a city of 700,000, has been called the most sustainable city in North America and it boasts, according to Toderian, the lowest greenhouse gas emissions per capita of any city on the continent. Even so, Toderian was quick to point out that Vancouver is still not sustainable. Fifty percent of the city’s homes, for instance, are single-family detached dwellings — that is, traditional sprawl.

In the video below, Toderian quickly describes some of the conditions (weak property rights in Canada) and decisions (removing inner-city freeways) that have made Vancouver such a livable city.

At the end of last month, government officials, architects, urban planners and researchers representing 71 nations converged on San Francisco for the 7th International Ecocity Conference, the Ecocity World Summit 2008. Staff writer Stacey Meinzen and I attended day one of the conference, which was held at the Nob Hill Masonic Center. In an upcoming series of Power Plug posts, we’ll link to video of presentations we found especially informative and inspiring.

Greening the Capitol

Amid the rancor that marks the congressional debate over appropriate legislative remedies to tackle climate change, what’s often lost on our lawmakers is that solutions exist, and they’re simpler than they might think.

Perhaps, to start, members of Congress should pay more attention to changes under way in their own offices. Dan Beard, the chief administrative officer of the U.S. House of Representatives, used his Ecocity talk to brief attendees on the “Green the Capitol” initiative. Stacey wrote about this ambitious program, which was initiated by Speaker Nancy Pelosi, in a post earlier this year (Power Plug, 1/3/08). Conveniently, Beard’s talk serves as a comprehensive update to Stacey’s January post.

Watch and be amazed as Beard punctures the inflated balloon that is Congress’ misplaced fear of economic doom wrought by combating climate change with his description of the Capitol’s systematic greening.

SolarCity Expands No-Money-Down SolarLease to Majority of Its California Service Area

In the most recent issue of e-Newswire, staff writer Stacey Meinzen wrote about a no-money-down solar lease offered by SolarCity to residents of San Jose through July 31.

Yesterday, a representative from SolarCity sent me an update announcing that the company was extending the same no-down-payment SolarLease (PDF, 49 KB) deal to the majority of its California service area.

Under the program, SolarCity assesses a homeowner’s electricity consumption and recommends a appropriately-sized photovoltaic (PV) system. For example, the company says a homeowner with a $150 monthly electricity bill can install a 2.4-kilowatt PV system for $0 down that would lower his or her monthly electricity bill to $40. The homeowner’s monthly lease payments to SolarCity of approximately $90 would be offset by the $110 monthly reduction in their electricity bill.

Green-Collar Jobs Offer Hope to Our At-Risk Youth and Ailing Economy

Although much of the U.S. economy is currently suffering, the green sector is enjoying growth while offering opportunities to lift people out of poverty. The Oakland Green Jobs Corps and Green for All campaigns, for example, are recruiting at-risk youth, training them for and helping to place them in green apprenticeships and employment. Providing peace of mind to workers and lawmakers alike, the jobs entail tasks that cannot be outsourced offshore — installing solar panels and wind turbines, and weatherizing homes and office buildings.

“We call it green pathways out of poverty — connect the people who most need the work with the work that most needs to be done,” Van Jones, founder of the Oakland Green Jobs Corps and the national Green for All campaign, recently told the Oakland Tribune.

Green-Collar Jobs in America’s Cities outlines local strategies for developing green-collar job initiatives and pathways out of poverty

Last year, Jones helped U.S. House Speaker Nancy Pelosi draft a bill for Congress, which passed as part of the 2007 energy bill (Power Plug, 12/18/07), that included $125 million for green-collar job training.

Jones has the attention of influential politicians outside California’s Bay Area as well. On the campaign trail, Democratic presidential candidates Hillary Clinton and Barack Obama and former candidate John Edwards have all talked about providing green-collar job training programs. Clinton co-sponsored the U.S. Senate version of the green-collar jobs amendment that landed in the 2007 energy bill. And, in February 2008, while campaigning in the manufacturing belt of the Midwest, Obama proposed a 10-year, $150-million green-collar jobs program.

Despite the global credit crunch, investment continues to pour into the renewable energy sector. Worldwide investment in clean technologies, renewable energy and energy efficiency grew 60% last year to $148 billion, according to figures published in February by New Energy Finance Summit, in London. According to Jones, the question is, “Will the new green wave lift all boats?”

If Jones has his way, it will do just that.

UC Santa Barbara Joins “LED University,” Studying Deploying LEDs Campus-Wide

If the per-unit costs of light-emitting diodes (LEDs) are to come down, major purchasers (i.e., government) will need to play a role. Recognizing this, North Carolina-based LED manufacturer Cree last year created the “LED City” campaign (Power Plug, 2/14/07), which now includes Raleigh, North Carolina, Ann Arbor, Michigan, Austin, Texas, and Toronto, Ontario, to engage local governments.

Last week, Cree launched a new initiative dubbed “LED University” to make use of the technical expertise — and purchasing power — of universities worldwide. The first schools to sign up are North Carolina State University, Marquette University, the University of Arkansas, Tianjin Polytechnic University, in China, and the University of California, Santa Barbara (UCSB).

The universities agreed to evaluate and use LED lighting in offices, dorms, parking garages, and along campus walkways and streets. Each of the universities is undertaking pilot projects to track the cost and energy savings from a switch to LEDs.

North Carolina State University installed LED recessed lighting from Cree in the chancellor’s office and a dormitory, and is adding Beta LED fixtures to campus parking garages. Marquette University installed EverLED (e-Newswire, 10/31/07) T8 fluorescent tube lighting replacements from LED Dynamics in an administrative office, and is installing LED recessed and task lighting. The University of Arkansas installed in the chancellor’s residence the first of nearly 1,700 recessed LED lights planned for the campus. And Tianjin Polytechnic University installed 1,500 LED street lights on the campus’ main roadway.

Here in California, UCSB’s involvement with LED University comes as no surprise. The campus is home to the Solid State Lighting and Display Center, which is co-directed by Shuji Nakamura, one of the world’s leading LED researchers (e-Newswire, 6/28/06). And Flex Your Power (e-Newswire, 4/02/08), among others, has recognized UCSB for its extensive energy-saving efforts.

For its LED University project, UCSB installed a test string of nearly two-dozen LEDs from Beta LED in street lights along a campus road. Officials say the LED fixtures have slashed electricity consumption by 44%. Now, UCSB is considering installing LEDs in street lights campus-wide.

Mother Jones Releases Special Report on “The Future of Energy”

Yesterday, Mother Jones* released online a special report titled “The Future of Energy.” In their Editors’ Note from the May/June issue of the print magazine, Monika Bauerlein and Clara Jeffery explain why today’s energy crisis, made more urgent by peak oil, climate change and the war in Iraq, is unlike any we’ve faced:

Switching away from fossil energy requires an economic and social transformation at least as great as the Industrial Revolution. And we have to build this new economy on the fumes of the old, hoping that we don’t run out of gas, or ice caps, before we get there. …

MJ Future of Energy

Building a new energy economy will require enormous government and private investment. It will involve massive workforce upheaval and possibly physical dislocation. The conservation measures demanded will make victory gardens or Jimmy Carter donning a sweater look like three-day diets. …

Today’s energy crisis is on a different scale. We’re reliant on an ever-more dubious cast of characters to provide us power. And if you think the mortgage meltdown is troubling, wait till the markets discover the real price of carbon and realize that our entire economy is, essentially, built on a planetary accounting fraud.

Along with dispelling some “Clean Energy Myths” and offering a list of “Bright Ideas” (”Solar-Powered Malls” and “Get Your Utility to Use Less Power”), the “The Future of Energy” includes “Power Q&As” with energy experts such as energy efficiency guru Amory Lovins; congressional energy efficiency and renewables champion Rep. Jay Inslee; Climate Progress blogger Joseph Romm and Google “green energy czar” Bill Weihl.

If you can pull yourself away from watching election returns come in from Pennsylvania on April 22, the UC Berkeley Journalism School is hosting a discussion with some of the writers and editors, including Bauerlein, who contributed to “The Future of Energy.” The free event runs from 6:30 p.m. to 8:00 p.m. at the journalism school’s North Gate Library.

*Editor’s Note: I served as an Editorial Intern and Editorial Fellow for Mother Jones from December 2001 - July 2002.

4 MW SolarWall Installation is World’s Largest Collection of Solar Air-Heated Buildings

Fort Drum, a U.S. Army base in upstate New York, now contains the world’s largest collection of solar air-heated buildings, with 50 SolarWall systems on 27 buildings that collectively generate over 4 megawatts (MW) of peak thermal energy. According to base officials, the SolarWall systems will prevent the release of 2,000 tons of carbon dioxide and save 44 billion BTU/h annually.

SolarWall uses a patented transpired solar collector developed by Conserval Engineering to heat air headed for ventilation ducts. Ventilation heating is typically one of the largest single energy requirements for large buildings such as the vehicle maintenance garages, warehouses and hangars at Fort Drum.

In 2005, the U.S. Army Corps of Engineers commissioned a multi-million dollar program to retrofit the 27 buildings. The next year, engineers identified SolarWall one of two cost-effective technologies suited to heating large military buildings.

Eight other U.S. military bases have deployed the SolarWall, including Fort Carson, Norfolk Naval Base, Fort Huachuca, Buckley Air Force Base, Fort Lewis, Peterson Air Force Base and, here in California, Edwards Air Force Base.
