Stanford Finds Future Of Solar Power Is Bright

Posted on June 17, 2012 by QuestPoint

Nearly everyone thinks that generating electricity via solar power is good for the environment, but there’s much less agreement on whether it makes sense from an economic point of view. At what point will solar power be competitive with electricity generated by conventional, fossil-fuel plants, and how long will subsidies need to remain in place before the solar industry can stand on its own? Those are some of the questions addressed in “The Prospects for Cost-Competitive Solar PV Power,” a new working paper by Stefan Reichelstein, William R. Timken Professor of Accounting at the Stanford Graduate School of Business, and Michael Yorston, graduate student in the Department of Management Science and Engineering at Stanford University. Their paper breaks new ground in studying the life-cycle cost of electricity generated by solar photovoltaic, paying particular attention to key factors such as location, public subsidies, and the long-term learning effects in manufacturing solar panels.

Concerning the future, and this may sound like a pun, the future of solar PV looks rather bright. The industry has consistently been able to lower the cost of solar panels. If this trend can be maintained for the next 10 years, and if subsidies are continued for that period, there is a real prospect for solar to become cost competitive on its own (that is, without a subsidy), at least for commercial installations. Utility-scale installations will take longer to become competitive; possibly 15 years, though it obviously becomes murkier to make projections that far into the future.

Renewable energy and solar in particular remain rather controversial in the public debate about energy policy. Passions have been running high. What motivated me is the bewildering range of statements you have out there regarding the cost effectiveness of electricity based on solar PV. Given the range of opinions, I wanted to do my own analysis. I’m looking at it from the point of view of a business economist who is interested in measuring the life-cycle cost of this abundant energy source.

Scientists Tap Into Underwater Solar Energy

Posted on June 14, 2012 by QuestPoint

Scientists at the U.S. Naval Research Laboratory (NRL), Electronics Science and Technology Division, dive into underwater photovoltaic research to develop high bandgap solar cells capable of producing sufficient power to operate electronic sensor systems at depths of 9 meters.Underwater autonomous systems and sensor platforms are severely limited by the lack of long endurance power sources. To date, these systems must rely on on-shore power, batteries or solar power supplied by an above water platform. Attempts to use photovoltaics have had limited success, primarily due to the lack of penetrating sunlight and the use of solar cells optimized more towards the unimpeded terrestrial solar spectrum.

“The use of autonomous systems to provide situational awareness and long-term environment monitoring underwater is increasing,” said Phillip Jenkins, head, NRL Imagers and Detectors Section. ”Although water absorbs sunlight, the technical challenge is to develop a solar cell that can efficiently convert these underwater photons to electricity.”Even though the absolute intensity of solar radiation is lower underwater, the spectral content is narrow and thus lends itself to high conversion efficiency if the solar cell is well matched to the wavelength range. Previous attempts to operate solar cells underwater have focused on crystalline silicon solar cells and more recently, amorphous silicon cells.High-quality gallium indium phosphide (GaInP) cells are well suited for underwater operation. GaInP cells have high quantum efficiency in wavelengths between 400 and 700 nanometers (visible light) and intrinsically low dark current, which is critical for high efficiency in lowlight conditions.

The filtered spectrum of the sun underwater is biased toward the blue/green portion of the spectrum and thus higher bandgap cells such as GaInP perform much better than conventional silicon cells, states Jenkins. Preliminary results at a maximum depth of 9.1 meters reveal output to be 7 watts per square meter of solar cells, sufficient to demonstrate there is useful solar power to be harvested at depths commonly found in nearshore littoral zones.The U.S. Naval Research Laboratory is the Navy’s full-spectrum corporate laboratory, conducting a broadly based multidisciplinary program of scientific research and advanced technological development.

Californians To Vote On GMO Food Labeling

Posted on June 13, 2012 by QuestPoint

Two nights ago, The California Secretary of State’s office announced that the Right to Know initiative to label genetically engineered foods will be on the state’s November ballot. The historic initiative would be the first law in the United States requiring labeling of a wide range of genetically engineered foods.“We’re thrilled that Californians will have the opportunity this November to vote for the right to know what’s in our food,” said Stacy Malkan, a spokesperson for the California Right to Know campaign. “This initiative is pretty simple. It’s about our fundamental right to make informed choices about the food we eat and feed our families.”The initiative requires labeling of genetically modified organisms (GMOs), which are plants or meats that have had their DNA artificially altered by genes from other plants, animals, viruses, or bacteria, in order to produce foreign compounds in that food. Nine out of ten voters in the U.S. and in California back labeling, according to recent polls (see Mellman 2012, Reuters 2010, Zogby 2012). An April poll by San Francisco TV station KCBS found 91% backed labeling.

The California Right to Know initiative is backed by a broad array of consumer, health and environmental groups, businesses and farmers. Major endorsers include Public Citizen, Sierra Club, American Public Health Association, United Farm Workers, California Certified Organic Farmers, Organic Consumers Association, Consumer Federation of America, Nature’s Path, Lundberg Family Farms, Organic Valley, Dr. Bronner’s, Eden Foods, Mercola.com, Center for Food Safety, Food Democracy Now! and the California State Grange. Grant Lundberg, CEO of Lundberg Family Farms in the Sacramento Valley, noted that the United States stands out as one of the few developed nations that does not provide consumers with simple labels to inform them if their food has been genetically engineered. “More than 40 other countries — including all of Europe, Japan and even China — already label genetically engineered food. Californians deserve to be able to make informed choices too,” Lundberg said.

In March, more than one million people submitted comments to the U.S. Food and Drug Administration on a petition for mandatory labeling of genetically engineered foods, more than any other petition in FDA history. Twenty states have tried to legislate GMO labeling, but none have succeeded due to intense opposition from corporate special interests.“All eyes are on California, and the voters of this state will support our right to know what’s in our food when they vote this November,” said Stacy Malkan from the Right to Know campaign.

Cali And Panama Conference Targets Renewable Energy

Posted on June 12, 2012 by QuestPoint

The 9th annual Global California Conference will be held at the San Jose City Hall this year on June 22nd. The topic is Panama and the Canal Expansion and its impact on California job creation. One of the presentations is about great renewable energy projects and investment opportunities in the West Coast of the U.S., Panama, Latin America, the Caribbean and the World: Massive Opportunity: Impact Capital for Renewable Energy Projects.

“Panama is poised is poised to become a key player in trade between Latin America and North America as well as Asia. Its geographic location favors a number of possibilities for players and surrounding countries” says panel guest, Rodney Alves of Alves & Associates.
“Panama’s strategic location is a major global shipping and logistics hub. The massive infrastructure improvements underway, including additional Ports and the Panama Canal Expansion, enhance the importance of the U.S.‐Panama Free Trade Agreement”, states Alvaro Cabal Lachman, President of USPAW.

Notable dignitaries from Panama as well as California will be participating in the conference, such as, former Ambassador to Panama in Washington D.C, Juan Sosa, who is now the President of USPA, U.S., will be giving the ‘keynote’ speech. The conference is produced by TradePort, the Monterey Bay International Trade Association in partnership with the United States ‐ Panama Business Council West.

Will Solar Energy Generation Silence EV Critics ?

Posted on June 11, 2012 by QuestPoint

Hybrid and electric vehicles are neither clean nor green according to a new environmental book, Green Illusions (June 2012, University of Nebraska Press), written by University of California – Berkeley visiting scholar Ozzie Zehner. Green Illusions exposes numerous hidden side effects of new hybrid and electric cars, such as the Tesla, Leaf, Fisker Karma, and Prius. The analysis considers mining impacts, toxins, energy use, suburban sprawl and carbon footprints of production. From an environmental perspective, Zehner argues that hybrids and electric cars are no better than gasoline vehicles, a conclusion backed by a National Academy of Sciences report.

“Shifting from gasoline to electric vehicles is like switching a smoking habit from cloves to menthols,” asserts Zehner. “It isn’t acceptable for doctors to promote menthol cigarettes — should environmentally minded people promote alternative fuel cars?” In a California radio interview yesterday, Zehner pointed out that the higher cost of electric cars reflects the greater quantities of fossil fuels used to build them. He argued that electric cars do not eliminate the negative side effects of vehicular travel. They merely shift the problems elsewhere. Most electric vehicle studies compare traditional gasoline fuel to electric car charging, which relies primarily on coal, natural gas and nuclear power. However, fueling activities represent only a portion of a car’s total environmental impact. Zehner points out that the larger impact comes from manufacturing the car. The added copper, aluminum, rare earth metals and other materials necessary for electric car production offset any benefit achieved during the entire charging lifecycle.

Even if mining companies clean up their operations and engineers increase battery storage capacity there is still a bigger problem looming on the horizon, argues Zehner. “Alternative-fuel vehicles stand to define and spread patterns of ‘sustainable living’ that cannot be easily sustained without cars. Suburban infrastructure maintenance and road construction induce ecological consequences beyond the side effects of the vehicle itself.”Instead of subsidizing electric cars, Zehner advocates for lawmakers to support smarter urban design policies that focus on walking, bicycling and public transit.

D’Angelo Plays Eco Arts Bonnaroo Music Festival

Posted on June 10, 2012 by QuestPoint

Rock the Earth, a national not-for-profit environmental organization that partners with the music industry, just held the largest music festival in the United States – the 11th Annual Bonnaroo Music and Arts Festival in Manchester, Tenn., June 7-10. Rock the Earth held a series of artist interviews and performances live on Bonnaroo’s Planet Roo Solar Stage, as well as a series of environmental films at the festival. To coincide with its environmental programming, together Rock the Earth and Bonnaroo held a cell phone recycling campaign that rewarded participants who recycled their old and unused mobile phones with free goodies and entry into the daily drawing for prizes.

Moderated by Rock the Earth’s founder and Executive Director, Marc Ross, the theme of this year’s performances and discussions on the Planet Roo Solar Stage were on “Social Change Through Music.” Attendees learned what inspires musicians to be activists, and explored the synergies between the artists that create music and music’s interconnectedness to the environment and world.

From Manchester, Tennessee the Newsfeed Resecher reported, “D’Angelo is back. The reclusive R&B singer made his first live U.S. appearance in 12 years at the Bonnaroo Music & Arts Festival early Sunday morning, surprising a few thousand fans during Ahmir “Questlove” Thompson’s Superjam session. “I’ve been waiting 12 years to say this ladies and gentlemen, D’Angelo!,” Thompson said as the crowd roared. It was his first U.S. show since 2000 and a prelude to an appearance at July’s Essence Music Festival and a European tour with many of the same players who backed him Sunday morning. D’Angelo played live in Europe earlier this year.”
