Sun Powers “The Rock”

Posted on by

Though the prison closed in 1963, 1.4 million visitors now tour Alcatraz each year. “The Rock” has been powered for 75 years by diesel fuel ferried across the bay. In 2012, a 280 kW solar photovoltaic system was installed on the roof of the island’s main cell house and provides roughly 66% of the island’s electricity needs. The solar array operates in combination with an extensive battery-based energy storage system to maximize solar electricity generation and use.

EN4A0310 300x213 The Next Generation In Solar Cars

The internationally recognized Sunswift solar car racing program at the University of New South Wales in Sydney, Australia recently debuted their revolutionary new solar racer “eVe”. The eVe not only inspires with its stunning design but also demonstrates long-term ecological sustainability. The students who volunteer their efforts to Sunswift created eVe in the hopes of capturing another team championship at the 2013 World Solar Challenge (WSC) – the pinnacle event for solar racing.

At this year’s WSC taking place in October  teams from top universities and private institutions around the world will compete in a 3,000 km race across Australia’s Outback from Darwin to Adelaide relying solely on the sun’s energy to power their cars. This year, eVe races in the ‘cruiser’ class, a class that rewards entrants for incorporating practical motoring features into their advanced solar technology vehicles.

Sunswift has teamed with ToyLabs to impart these invaluable science lessons to school kids. The Sunswift team uses the Volta Racer to share their passion and to inspire future generations of scientists and engineers through a series of hands-on workshops located at the University of New South Wales Engineering School and at various location en-route to WSC. During the workshops kids get to build the Volta Racer and learn about Sunswift’s innovative work on eVe. UNSW engineering student and Sunswift Project Director ‘Alex To’ went so far as to liken the Volta Racer to a “miniature version of the car we build. Both vehicles, in fact, use the same direct solar to power conversion methods to provide electricity to their motors. The Volta Racers allow these kids to have a practical hands-on experience building their very own electric car while learning about basic mechanical engineering, electronics and using solar as a sustainable energy application.”ToyLabs founder ‘Tim Curley’ is honored to lend his support to Sunswift’s efforts. “ToyLabs wants to help inspire kids to become the world’s next generation of scientists and engineers – just like the extremely bright students at UNSW working on eVe.“

Top Ten Eco Cities

Posted on by

With Earth Day just around the corner, Redfin, a technology-powered real estate broker, today announced a ranking of the country’s top 10 cities with the greenest homes. The Redfin analysis looked at each city’s overall carbon dioxide emissions, as well as the number of homes currently for sale that have “green” features or eco-friendly ratings. Examples include solar panels, low-flow faucets, dual pane windows, ENERGY STAR® appliances, LEED certified homes, and new construction by green builders. LEED stands for Leadership in Energy and Environmental Design, and is the most widely used green building program worldwide.

  1. San Francisco, CA – In addition to having the lowest carbon dioxide emission rate per capita, San Francisco has a large number of homes for sale with eco-friendly features. One incentive for locals to go green may be Pacific Gas & Electric’s rebates, which offer up to $4,000 for home energy upgrades including insulation and air duct sealing.
  2. Washington D.C. – According to the U.S. Green Building Council, Washington D.C. has the most (LEED)-certified space, which likely contributes to the city’s low carbon dioxide emission rates. In addition, the district offers a number of rebates and tax credits for residential energy efficiency, which may help explain the high number of homes for sale with eco-friendly features.
  3. Sacramento, CA – Sacramento has the second-lowest carbon dioxide emissions in the country, and new developments have focused on energy-efficient homes, such as the Northwest Land Park, which will build 800 new homes that use net-zero electricity.
  4. Boston, MA – Boston Mayor Thomas Menino launched an initiative to be “Green by 2015,” which includes powering homes using a combination of waste products and solar panels. The city also supports the Energy Positive “E+” Green Building Demonstration Program, which aims to bring green homes to Boston’s neighborhoods.
  5. Portland, OR – Portland General Electric offers residents the choice to pay a little more for renewable energy options, including wind-sourced power. In addition, Portland residents who want to make their home more green can attend Fix-It Fairs, which offer resources and information to help attendees reduce water and energy usage, among other green initiatives.
  6. Philadelphia, PA – Even though Philadelphia’s carbon dioxide emissions were higher than other cities, it ranked second for homes with eco-friendly features. In 2009 the city passed two laws that advance green building practices. The first requires that new city government buildings meet LEED Silver Certification, and the second requires all new construction to have “cool roofs” that meet or exceed Energy Star standards.
  7. Phoenix, AZ – As part of the “Green Phoenix” initiative, Phoenix offers a one-time grant to homeowners for making improvements that reduce energy consumption. The city has also received funding to retrofit low-income residential homes with cost effective energy saving measures. 
  8. Los Angeles, CA – Homeowners looking to reduce costs associated with air conditioning in L.A.’s warm climate can take advantage of the L.A. County’s Energy Loans Program, which offers loans of up to $50,000 dollars with financing as low as 4.99% when homeowners undertake home energy improvements. In addition, Energy Upgrade California offers rebates of up to $4,000 to homeowners who make their home more energy efficient. To see some stylish green homes on the market in L.A., check out this Redfin Collection.
  9. Seattle, WA – Seattle residents are known for being eco-conscious, as evidenced by the recent ban on plastic bags, so it’s not surprising they’d want their homes to be green too. Although the city is known for its rain, Seattle receives more sunlight than Germany, the world’s leading solar market, and Washington State offers financial incentives for those who generate their own electricity using solar electric systems.
  10. Austin, TX – Austin Energy is the nation’s top seller of renewable energy, and the company offers homeowners low-interest loans of up to $20,000 dollars for energy efficient upgrades. In addition, the company offers rebates for numerous upgrades, including extra attic insulation, high-efficiency clothes washers, rainwater collection barrels, and low-flow toilets.

“The residents of these cities are reducing their environmental footprint and saving money at the same time,” said Julie Jacobson , a LEED Green Associate certified Redfin Agent. “By making your home green, you can reduce monthly utility bills, make your home’s indoor air quality healthier, reduce your environmental footprint and even help increase the value of your home without any sacrifice in design or comfort. It is truly a win-win.”

The Politics Of Solar Power

Opinion: All Solar Wants is a Level Playing Field – Justin Pentelute.
Fine for now, but we have to focus on a major point:  continuing national and state institutional support of solar is essential.  It needs to be a broad, long-term priority.  In a political climate that is partisan and contentious, support for energy innovation sometimes gets lost in the ether.  That’s a mistake. 

In this same category, I am disappointed in the actions of some state legislatures and utility regulatory commissions.  Some have acted with disturbing inconsistency, setting helpful programs in place that foster solar installations and then pulling the plug on them before the benefits have really taken hold.  What’s equally disturbing is what I call “the race to unviability,” where programs are put in place to imminently fail and be canceled.  It seems unfair for homeowners’ access to affordable solar electricity to depend on the state in which the home happens to be built and the all-powerful utility company that provides their electricity. This is a countrywide priority and we should deal with it that way.

Think of the societal good that comes from continued development and implementation of solar electricity.  There would be less carbon in the atmosphere if our electric utilities can build fewer new fossil-fuel power plants.  That could happen because solar electric can supplement power-grid electricity generated by these plants.  Moreover, solar electricity often feeds into the grid when its output exceeds its need in residential and other applications.  That’s a plus because not many electric utilities today are anxious to build expensive new generating plants…Read on>

sam adamsX390 300x219 Portland Mayor Welcomes SoloPower SoloPower, the San Jose, California-based leader in high efficiency, lightweight, and flexible thin-film solar cells and modules, recently  announced  the grand opening in Portland, Oregon of its high-volume manufacturing (HVM) facility. The event marked a significant milestone in the company’s plan to make solar energy the primary source of power for commercial and industrial buildings worldwide, and in its ability to meet demand for its unique solutions. SoloPower was joined at the ceremony by Portland Mayor Sam Adams who toured the state-of-the-art manufacturing floor with local and state elected officials, company executives and customers. “Oregon’s manufacturers are playing a key role as we add jobs back to Oregon,” said Governor Kitzhaber. “With the opening today of this high-volume manufacturing facility, we mark a significant milestone for SoloPower and for advanced manufacturing in Oregon.”

“Portland congratulates SoloPower on the grand opening of its operations here, which are ultimately expected to employ 450 people. We have worked proactively and collaboratively to nurture the success of our local industry of which SoloPower is a growing part,” said Mayor Adams. “Portland benefits when we help maximize the global competitiveness of local businesses. SoloPower is creating living-wage jobs in a vital sector of our economy, a sector that is helping to establish Portland as one of the most sustainable economies in the world.”

SoloPower‘s lightweight, flexible SoloPanels and proprietary installation systems revolutionize the rooftop solar integration process, making solar energy easy and cost effective for nearly any commercial and industrial building. The company’s suite of solar solutions optimizes energy performance on a variety of roofs in a range of climates with diverse sun exposure conditions. Non-penetrating installation systems make it simple to remove and reinstall SoloPower‘s solutions, enabling installation on older roofs not yet due for a reroof and substantially expanding the market beyond new and reroof applications. Due to their very low profile on rooftops, SoloPower‘s solutions provide an unparalleled ability to withstand wind, opening additional segments that could not utilize solar energy in the past, particularly in areas susceptible to storms, such as Japan.

“The opening of SoloPower‘s state-of-the-art HVM facility in Portland increases our capacity to meet the energy demands of the world’s commercial and industrial buildings, which consume 40% of global electricity,” said Tim Harris, CEO, SoloPower. “Both we and our customers are very excited: It’s a huge market, our unique solutions expand that market, and now we have the ability to serve our customers who are looking for an easy-to-install, predictable, and cost-effective solution for their energy needs, no matter their continent.”

SoloPower‘s operations in Portland are ultimately expected to have a capacity of 400MW.
