Organic Solar Cells Sparking Consumer Electronics

Posted on October 30, 2011 by quest

Molecular Solar Ltd, a spinout company from the University of Warwick, has achieved a significant breakthrough in the performance of solar photovoltaic (PV) cells. They have achieved and demonstrated a record voltage for organic photovoltaic cells that means these highly flexible, low cost solar cells can now be devolved for commercial uses in a wide range of consumer electronics. The Company’s most recent advance in the development of its organic photovoltaic (OPV) cell technology is the realisation of cells with open-circuit voltages in excess of 4 volts for the first time. Molecular Solar’s research team believe this is a record for an OPV device. Dr Ross Hatton, Research Director of the company commented:
“This is an important advance. We are now very close to having highly flexible organic photovoltaic cells that will be capable of delivering electrical energy at a voltage suitable for recharging lithium ion batteries that are widely used in portable consumer electronics. Remarkably, this high voltage is achieved using a cell with only 4 junctions (sub-cells)’’.University of Warwick researcher Professor Tim Jones, who is Chief Technology Officer of Molecular Solar, added:

“The first generation of organic photovoltaics will be exceptionally well matched to consumer electronics applications. The advantage of Molecular Solar’s high voltage cells is that a single cell can be used with no requirement to connect multiple cells in series for these applications, saving manufacturing cost. ’’Andrew Oldfield, Head of Cleantech at Mercia Fund Management said, “We were attracted to Molecular Solar’s unique approach to realizing truly flexible, environmentally sustainable photovoltaics that are well matched to the burgeoning portable consumer electronics market.”

Solar Energy To Power Vertical Forrest In Milan

Posted on October 30, 2011 by quest

Bosco Verticale is a project for metropolitan reforestation that contributes to the regeneration of the environment and urban biodiversity without the implication of expanding the city upon the territory. Bosco Verticale is a model of vertical densification of nature within the city. It is a model that operates correlated to the policies for reforestation and naturalization of the large urban and metropolitan borders (Metrosbosco). Metrobosco and Bosco Verticale are devices for the environmental survival of contemporary European cities. Together they create two modes of building links between nature and city within the territory and within the cities of contemporary Europe.

The first example of a Bosco Verticale composed of two residential towers of 110 and 76 meters height, will be realized in the centre of Milan, on the edge of the Isola neighbourhood, and will host 900 trees (each measuring 3, 6 or 9 m tall) apart from a wide range of shrubs and floral plants. On flat land, each Bosco Verticale equals, in amount of trees, an area equal to 10.000 sqm of forest. In terms of urban densification the equivalent of an area of single family dwellings of nearly 50.000 sqm. The project is now underway.

The future of vertical farming in Italy

The Bosco Verticale is a system that optimizes, recuperates and produces energy. The Bosco Verticale aids in the creation of a microclimate and in filtering the dust particles contained in the urban environment. The diversity of the plants and their characteristics produce humidity, absorb CO2 and dust particles, producing oxygen and protect from radiation and acoustic pollution, improving the quality of living spaces and saving energy. Plant irrigation will be produced to great extent through the filtering and reuse of the grey waters produced by the building. Additionally Aeolian and photovoltaic energy systems will contribute, together with the aforementioned microclimate to increase the degree of energetic self sufficiency of the two towers. The management and maintenance of the Bosco Verticale’s vegetation will be centralised and entrusted to an agency with an office counter open to the public.

Electric Vehicles A History of Moving Americans Reborn

Posted on October 29, 2011 by quest

The popularity of mass-produced electric or hybrid cars is recent, but the idea behind using electricity as a power source for cars is more than 100 years old. The Smithsonian’s National Museum of American History will explore the history of the electric car from the early 20th century to the present in a new display as part of the “America on the Move” exhibition opening Oct. 27 through January 2012. “Electrifying Cars” showcases two cars—a 1904 Columbia electric runabout, the best-selling car in the United States at the turn of the century and a 1913 Ford Model T touring car, a gasoline car equipped with an early type of electric starter and electric headlights. The cars, along with a battery charger for General Motors’ EV1 and images of additional electric models, car owners and power sources, follow the historical, cultural and physical development of the electric car.

A look at electric vehicles in history

“Electricity has always been a popular feature of cars,” said Roger White, associate curator of Road Transportation. “By the 1920s manufacturers used batteries not to propel cars but to apply the conveniences of electric cars to gasoline-powered cars.” He added that in recent years a market has developed for all-electric cars and hybrid cars with gasoline and electric propulsion because they reduce energy costs and air pollution. “These cars can draw energy from a variety of sources including fossil fuels, regenerative braking and renewable sources such as solar panels and wind power,” he said.

In the early 20th century, Americans could choose electric, steam or gasoline cars. Wealthy city residents, particularly women, bought electric cars because they were easier to operate. By the 1920s, gasoline-powered cars were the vehicle of choice because they could be driven much farther than electric cars between fill-ups, and gasoline pumps, unlike electric power stations, could be readily located anywhere. Since the 1960s, smog, greenhouse gases, global warming and strained oil supplies have prompted researchers, government and the public to take a new look at electric hybrid and all-electric cars. In the 1990s GM and other manufacturers worked to put electric cars on the market. GM’s EV1, Honda’s EV+, Ford’s Ranger EV and Toyota’s RAV4 EV were leased. But by 2003, the manufacturers determined that the electric car was not commercially viable and ended the leases. By 2010, the market led to the reintroduction of electric cars, and for the first time in almost 100 years consumers could purchase all-electric or new types of hybrid cars.

The Western Solar Energy Zone

Posted on October 28, 2011 by quest

As part of President Obama’s commitment to developing our domestic energy portfolio, including our clean energy resources, U.S. Secretary of the Interior Ken Salazar recently made public a supplement to the federal plan to facilitate responsible utility-scale solar development on public lands in six western states – Arizona, California, Colorado, Nevada, New Mexico and Utah. The revised plan, the Supplement to the Draft Programmatic Environmental Impact Statement for Solar Energy Development (Solar PEIS), reinforces and improves upon Interior’s work to establish meaningful solar energy zones with transmission solutions and incentives for solar energy development within those zones. The blueprint’s early, comprehensive analysis will ultimately make for faster, better permitting of large-scale solar projects on public lands.

“Between the proposed solar energy zones, the flexible variance process, the additional state-based planning efforts, and the commitment to process pending applications, Interior is taking an ‘all-hands-on-deck’ approach to building a strong solar energy economy now and into the future,” said Deputy Secretary David J. Hayes.

How The West Was Won

“Tapping the vast potential of solar resources in the Western states will go a long way to diversifying the country’s energy portfolio and re-establishing our position as a clean energy leader in a global market worth trillions of dollars in the long term,” said U.S. Energy Secretary Steven Chu. “Advancing the deployment of utility-scale solar projects will not only help provide clean power to local utilities, it will also drive down the cost of solar energy and create American jobs in the rapidly-growing clean energy economy.”

SolarWorld Walks The Sustainability Talk

Posted on October 28, 2011 by quest

SolarWorld, the largest U.S. solar panel manufacturer, has been recognized by three independent rankings as the global renewable-energy industry’s leader in sustainable corporate management, environmentally sound manufacturing and transparent financial reporting.The 2011 annual report of the Carbon Disclosure Project (CDP) for Germany, released in Frankfurt in mid-October, positions SolarWorld as the “Sector Leader” among its renewable energy peers. The CDP is a cooperative endeavour by more than 551 institutional investors worldwide to improve corporate transparency on greenhouse gas emissions affecting the climate. To this end, participating companies voluntarily report their annual C02 emissions and their strategies and steps toward climate protection. SolarWorld was deemed to most fully disclose its data, placing the company at the top of the CDP’s ranking.

Kevin Kilkelly, president of SolarWorld Americas said, “As a company, we believe it is not valid to claim to sell a green product if your own business and manufacturing practices are not equally sustainable. Sustainability – environmental, social and fiscal – is at the very core of who we are and what we do.” Earlier this year, the Silicon Valley Toxics Coalition (SVTC), a watchdog group that has monitored the sustainability of the computer and solar industries, ranked SolarWorld first among world solar producers on a range of issues pivoting on sustainable performance. Among factors was the company’s voluntary compliance with reporting regimens encompassing a company’s entire impact, one of which is the U.N.-backed Global Reporting Initiative.

SolarWorld’s performance on the SVTC’s Solar Scorecard was the second year in a row in which the company ranked highest among producers of crystalline silicon solar technology on the only annual ranking of all solar companies on sustainable performance.For the high quality of its financial reporting, SolarWorld also received accolades in this year’s “Best Annual Reports” competition by Manager Magazine. With its integrated financial and sustainability reporting, which includes environmental and social key performance indicators, SolarWorld outpaced all other companies in the renewable-energy sector.

Solar Powering 10,000 Climate And Water Saving Homes

Posted on October 27, 2011 by quest

Build It Green, a California leading expert on residential green building, announced a major milestone today: 10,000 single- and multi-family homes will receive the GreenPoint Rated label, representing the gold standard in green home construction and remodels, by the end of 2011.These GreenPoint Rated homes are saving California over 112 million gallons of water — enough to fill Crystal Springs Reservoir five times over — and avoiding nearly 9,000 tons of greenhouse gases, the equivalent of taking over 1,500 cars off the road for a year. According to the U.S. Environmental Protection Agency, an estimated 17 percent of the nation’s greenhouse gas emissions are from residential homes each year. GreenPoint Rated is designed to help homeowners and builders ensure their home or development is built or remodeled to meet high environmental standards. Like a report card for green homes, the rating system assigns points based on five categories: Energy Efficiency, Resource Conservation, Indoor Air Quality, Water Conservation and Community Benefits. Point values are determined based on the use of verified green construction practices and sustainable materials that exceed California’s residential building and energy code requirements.

To ensure a home is built or remodeled to maximize efficiency and minimize environmental impacts, GreenPoint Rated assesses points based on green building techniques including: Increasing energy efficiency by implementing energy saving construction techniques and equipment such as solar power, solar water heating and ENERGY STAR appliances. The GreenPoint process also includes; Conserving water, creating livable communities, enhancing quality of life and minimizing pollution through community benefits like proximity to public transportation, stores and other services. “In designing my green home, it was important to me to create a home that is not only good for the environment today, but establishes a legacy of sustainable living practices for my children and future generations,” said Ian Macleod, owner of a GreenPoint Rated home in Albany, CA that won the American Institute of Architects, San Francisco Chapter, Energy + Sustainability Citation Award in May 2010. “As an architect and Certified Green Building Professional myself, I knew the GreenPoint Rated label represented the high environmental standards I wanted for my family’s home.”

In addition to environmental benefits, homes that have been built or remodeled using green building techniques have been shown to lower the cost of monthly utility bills, home maintenance and repairs. Early research also indicates that green homes may retain their value better, even in a tough real estate market, and are attractive to a growing number of homeowners and buyers.“With so many homeowners and developers now building green, we could see the number of GreenPoint Rated homes in California double over the next five years,” said Tenaya Asan, Build It Green’s senior program manager for GreenPoint Rated.
