Solar Energy Innovations In San Francisco

Posted on June 29, 2012 by QuestPoint

The San Francisco Public Utilities Commission’s new environmentally sustainable headquarters building at 525 Golden Gate Avenue, designed in joint venture by KMD Architects and Stevens Architects, provides a poster-child of sustainability innovation for urban office buildings, and reflects the mission of the PUC as a provider and manager of water and energy for San Francisco. All told, 525 Golden Gate in comparison to similarly-sized office buildings features 50% less of a carbon footprint, uses 32% less energy, and consumes 60% less water.The 13-level, 277,511 gross-square-foot, $190 million SFPUC headquarters building is one of the greenest urban office buildings of its kind, bringing together in a modern, contextually-designed office tower some of the most innovative new technologies at the forefront of building design.

“What better organization than a major municipal power and water agency to create one of the most advanced buildings in green design in the U.S.,” said David Hobstetter, Principal of KMD.“Our intent from the beginning was to create the most energy-efficient office building developed in an urban setting in the United States to date,” said Ryan Stevens, KMD’s Director of Design. “Many of these features are uncommon in buildings today, but will be commonplace in years to come.”

A wind turbine tower on the north facade, solar panels on sunny exteriors, sun-shading and other techniques combine to make the building one of the most power-efficient anywhere, using 32% less energy than similarly-sized office buildings. The integrated, hybrid solar array and wind turbine installation can generate up to 227,000 kilowatt hours per year or 7% of the building’s energy needs. A state-of-the-art raised flooring system incorporates the building’s data and ventilation infrastructure and reduces heating, cooling and ventilation energy costs by 51%. Daylight harvesting that bounces sunlight at appropriate amounts into workspaces saves electricity and minimizes artificial lighting, and enhances worker productivity. Other techniques include automatic shut-off sensors after hours for lighting and work station equipment.

American Clean Energy Agenda

Posted on June 28, 2012 by QuestPoint

Fed up with the undue influence of the energy companies, utilities, lobbyists and other interests that are making it impossible for Washington to move forward decisively in achieving America’s clean energy future, 36 citizen organizations with more than 1.1 million combined members are joining forces to advance a nine-point “American Clean Energy Agenda” and to push for a serious renewable energy agenda no matter who is the next President or which party controls Congress.

As crafted by the groups, the new American Clean Energy Agenda calls for a number of bold steps, including: phasing out nuclear power, natural gas, coal and industrial biomass in favor of efficient use of renewable, non-polluting resources; opposition to a “clean energy standard” that includes coal, nuclear, oil, gas and unsustainable biomass; retooling federal “loan guarantees” to make smarter investments in renewable energy; greater emphasis on renewable energy and energy efficiency programs; and avoiding a future in which Americans suffer the consequences of mountaintop mining for coal and fracking of shale gas that is then exported for use in other nations.

Organized by the nonprofit Civil Society Institute (CSI) and the Environmental Working Group (EWG), the emergence of the new network of citizen-run organizations reflects a deep dissatisfaction among Americans about the iron grip maintained by the energy industry and its lobbyists in promoting the non-solution of an “all of the above” approach to energy that would preserve the worst options and dilute the focus on real solutions.

Waves Of Change At Rio+20 Sustainability Conference

Posted on June 21, 2012 by QuestPoint

Secretary-General Ban Ki-moon speaking yesterday at the Rio+20 Conference on Sustainable Development outlined a series of actions he believes the global community must take over the next five years to build the future we want. In a speech to the General Assembly last September Mr. Ban presented five imperatives or generational opportunities that must be addressed to ensure a better future for the world’s people. These are sustainable development; preventing and mitigating conflicts, human rights abuses and the impacts of natural disasters; building a safer and more secure world; supporting countries in transition; and working to engage the talents of women and young people. Today I want to share with you an action agenda for the coming five years, he told the Assembly as he returned to the rostrum to brief Member States on his vision for his second term.

A plan to help create a safer, more secure, more sustainable, more equitable future. A plan to build the future we want. A plan to make the most of the opportunities before us. A plan to help create a safer, more secure, more sustainable, more equitable future. A plan to build the future we want, he said. The action agenda presented today describes specific measures regarding each of the five imperatives, including an unprecedented campaign to wipe out five of the world’s major killers malaria, polio, paediatric HIV infections, maternal and neonatal tetanus, and measles.

Mr. Ban also announced that the UN will work with Member States to make Antarctica a World Nature Preserve and that he will appoint a new special representative for youth. Among his other proposals is the convening of a first-of-its-kind World Humanitarian Summit to help share knowledge and establish common best practices, and the creation of a New UN Partnerships Facility to harness the full power of transformative partnerships across the world body. Waves of change are surging around us, he told the Assembly. If we navigate wisely, we can create a more secure and sustainable future for all. The United Nations is the ship to navigate these waters.

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.

California Leading US Clean Energy Revolution

Posted on May 31, 2012 by quest

Clean Edge’s third annual State Clean Energy Index, released today, provides the industry’s most comprehensive and objective analysis of how all 50 states, and the individuals, businesses, and organizations that operate there, compare across the clean-energy spectrum. According to Clean Edge’s assessment and ranking of more than 70 different indicators in technology, policy, and capital, the top 10 states in the nation this year are California, Oregon, Massachusetts, Washington, Colorado, New York, Illinois, New Mexico, Vermont, and Minnesota.

Clean Edge managing director Ron Pernick said,“Against the backdrop of partisan attacks and general inaction within Congress, the state-level scene shows a diversity that crosses political boundaries and regions. The next decade will determine which nations, states, and cities lead in clean tech, and our State Index provides critical insights on the dramatic shifts and best practices that are leading the way within the U.S.” Key market indicators tracked by Clean Edge via its State Clean Energy Index subscription service include total electricity produced by clean-energy sources, hybrid and electric vehicles on the road, clean-energy venture and patent activity, and policy regulations and incentives. The 2012 State Index paints an important and insightful picture of the U.S. clean-energy landscape. For example; California’s clean-energy venture capital dollars in 2011 exceeded the total of all the other 49 states combined. The number of registered hybrid cars in the U.S. grew to nearly 2 million while all-electric vehicles neared the 50,000 registered-vehicle milestone. Six states, twice as many as last year, now generate more than 10 percent of their utility-scale electricity from wind, solar, and/or geothermal.

An executive summary of this year’s State Index is available. The executive summary provides a glimpse at topline findings from the State Clean Energy Index report, the centerpiece of a larger advisory subscription service. Along with access to the full State Index report – containing detailed Index results, comprehensive data tables, and individual state report cards – subscribers receive custom presentations, clean-tech company database access, and advisory hours.

Russian Students On Global Energy Adventure

Posted on May 29, 2012 by quest

The Energy of Adventure, organized by the non-profit partnership Global Energy, announced in Moscow that two young Russians have won a round-the-world trip to discover the most interesting energy-related stories of the planet. The two researchers, Maria Khromova, a young Muscovite engaged in the power industry, and Egor Goloshov, a future economist from Zlatoust will be taking a trip around the world to 21 countries over a period of three months. The project Energy of Adventure, instituted by the non-profit partnership Global Energy, got under way last November with a nationwide contest. Every day Egor and Maria will share with the global community their power industry impressions and findings, and their small adventures through social networks such as Twitter and Facebook.

“Travelling around the world is always an interesting experience. I have been given this unique opportunity to tell the world about the most important energy-related discoveries, and it’s no secret that the power industry is an integral and key part of the economic stability of any country. I plan to use this unique material to write a scientific paper,” said Maria. Egor Goloshov began to think about energy conservation back in school. Egor has a special interest in renewable sources of energy such as tidal, wind and solar energy. Egor is currently a student enrolled in the Moscow Higher School of Economics. “I have always been aware that traditional sources of energy are running out. I am truly elated that I have been given the honour to tell people all over the world about what are definitely important problems in the modern-day power industry. I will do everything in my power, and even more, to meet the challenges entrusted to me under this project,” Egor pledged.

The main purpose of Energy of Adventure is to draw attention to contemporary global and local energy issues and inspire people to ponder over possible solutions. The president of the non-profit partnership Global Energy, Igor Lobovsky, commented: ” These are real steps and real efforts. This is why talented young people will be crisscrossing the globe in a bid to draw valuable experience from people, companies and authorities in the most far-flung corners of the planet. This is a great opportunity and also an onerous responsibility.”Interest in this unique project has been tremendous, with about 49,000 applications submitted from people in 50 cities across Russia.
