Despite the initial higher cost for solar shingles compared with asphalt shingles, homeowners will only need to use solar shingles on part of a roof, and their use will save consumers money in the long run, according to Pezolt.
“The Powerhouse solar shingles … will typically offset 50 percent of the electricity usage” and it is not necessary to use them on the entire roof, Pezolt said. “I think it would be fair to assume you would only dedicate 20-40 percent of your roof [usually the south-facing side] for solar shingles,” he said.
The solar cells are integrated by Dow into a proprietary polymeric-based shingle through injection molding. The interlocking shingles are designed to be used alongside asphalt shingles on a standard roofing underlayment. They can be installed with standard roofing nails at the same time as asphalt shingles. That continues to be a positive aspect, based on early installations that have been done in Spring Mesa, said Pezolt.
“You can install the solar shingles in the same amount of time using the same tools,” he said. “They are putting [the roofing] up very quickly.”
The three-part solar roofing system package includes an array of shingles, an inverter and an energy-monitoring system. The shingles are arranged to complement the style and form of the home and roof line. The inverter then converts direct-current produced from the shingles into alternating current, which is then fed to the home’s appliances or back to the power grid.
Dow’s solar business received $20 million in funding in 2007 from the Department of Energy to develop new residential solar products.
Edit.: YES, you read correctly. Dow got $20 million from taxpayers to fund the development of this product. $20 million is not even a rounding error to Dow and I think the money should have been spent helping a start up company (or 100 start up companies) get themselves into business. My opinion.
The April Fool’s Day Blizzard was a major winter storm in the Northeastern United States on March 31 and April 1, 1997. The storm dumped rain, sleet, and snow fromMaryland to Maine leaving hundreds of thousands without power and as much as three feet of snow on the ground.

It is has long been the wish of the salad industry to find a way to ensure perfect sanitisation of related produce. Since 2006, and a particularly virulent E.coli outbreak the hunt has been on for methods by which food safety standards can be improved.
The outbreak did, after all, cost the fresh salads industry and eye watering $350 million in lost sales and product recalls.
Since then heralded advances have always focused on the use of chlorine washes or testing technology, which leaves the organic sector with little recourse to food safety actions.
As a result of this Earthbound Farm teamed up with the Institute for Food Safety and Health (IFSH) at the Illinois Institute of Technology to look for solutions outside the bag. One of the promising directions of research uncovered so far is a little surprising - high power ultrasound.

On Springwise we’ve seen countless products brought into being through crowdfunding, but what happens to the projects once the funding is complete? TinyLightbulbs aims to keep businesses thriving by providing a marketplace for such enterprises.
While sites such as Kickstarter provide a popular platform for small startups to get their ideas heard about and funded, the group behind TinyLightbulbs suggests that once those startups reach their target, they no longer have the backing of a frequently visited site to support and market their products. Acting as a marketplace for those independent businesses that have completed their fundraising drives, the website aims to promote new products, sell them, and offer advice to small businesses. The site features video reviews of new merchandise and is hoping to build a community for startups. This short motion graphic explains some of the ideas behind the site:
Crowdfunding has proved how valuable it can be helping startups get their feet off the ground, but as regular readers of our Wise Words series will be all too aware, that’s often only the first of many hurdles. Time to set up a marketplace like TinyLightBulbs in your area or for a particular niche?
Gardening when you’re distracted or in a hurry is a problem. You wonder if you planted rutabagas in two rows or three. You can’t tell if the newly emerging Brassica plants are cauliflower or broccoli. And unless you taste them, it’s not easy to tell if you’re pulling weeds or tender garlic shoots. That’s why I rely on plant markers instead of my memory.
I’ve tried all sorts of markers. I like the rustic look of writing plant names on ribbons and tying them to twigs stuck in the ground, but my dogs are pretty sure those twigs need to be in their mouths. Plant names written on wooden popsicle sticks also work, but the sticks are small and hard to see after a few weeks.
So I use iced tea spoons to make garden markers. They’re durable, easily visible, and can be saved for reuse. Your kids can do the artwork.
It can be quite hypnotizing to watch the gusty trails blast across the American continent, skitter over the Sierras, get roughed up by the Rockies, and whoosh over the great plains on its way to Canada. (Which seems to give as good as it gets, sending most of its wind towards New York.)
Wind patterns are constantly changing, of course, which is why the Wind Map designers have also given us a moving-image gallery of previous blustery days.

Food Forward goes way beyond celebrity chefs, cooking competitions, and recipes to reveal the compelling stories and inspired solutions envisioned by food rebels across America who are striving to create a more just, sustainable and delicious alternative to what we eat and how we produce it. Created by a veteran documentary film making team led by Greg Roden, Food Forward explores new ideas of food in America as told by the people who are living them. Each episode will focus on a different theme—school lunch reform, urban agriculture, sustainable fishing, grass-fed beef, soil science—and spotlight the real people who are creating viable alternatives to how we grow food and feed ourselves.

“During his presidential campaign, Barack Obama promised to “create a centralized Internet database of lobbying reports, ethics records and campaign finance filings in a searchable, sortable and downloadable format.” Last week, President Obama fulfilled that promise with the rollout of Ethics.gov, which “brings records and data from across the federal government to one central location, making it easier for citizens to hold public officials accountable.”
Ethics.gov is available to the public and allows anyone to access and search the records of seven different databases:
• White House Visitor Records;
• Office of Government Ethics Travel Reports;
• Lobbying Disclosure Act Data;
• Department of Justice Foreign Agents Registration Act Data;
• Federal Election Commission Individual Contribution Reports;
• Federal Election Commission Candidate Reports; and
• Federal Election Commission Committee Reports.
According to a White House press release, the database includes millions of White House visitor records, records for entities registered with the Federal Election Commission such as PACs, records for each candidate who has either registered with the FEC or appeared on a ballot list prepared by a state elections office, lobbying registrations, and much more.
On his Sunlight Foundation blog, John Wonderlich, who is Policy Director for the Sunlight Foundation and an advocate for open government, wrote that while Ethics.gov fulfilled the president’s pledge, “neither money and politics research nor executive branch oversight are going to be revolutionized by this search page — at least not yet.” He added that while it will not happen immediately, the site could become a primary destination for investigative journalists or ethics officials.”

Oil prices are now higher than they have ever been—except for a few frenzied moments before the global economic meltdown of 2008. Many immediate factors are contributing to this surge, including Iran’s threats to block oil shipping in the Persian Gulf, fears of a new Middle Eastern war, and turmoil in energy-rich Nigeria. Some of these pressures could ease in the months ahead, providing temporary relief at the gas pump. But the principal cause of higher prices—a fundamental shift in the structure of the oil industry—cannot be reversed, and so oil prices are destined to remain high for a long time to come.
