Study: It’s Cheaper to Shut Down Wind Turbine, Than to Pay for Energy Storage

       

A new study finds that it may be better for the environment to temporarily shut down a wind turbine than to store the surplus electricity it generates. (Credit: Flickr - FranceHouseHunt.com)

Conventional grid-scale batteries are fine for solar farms, but technological improvements are needed for efficient storage of wind power, Stanford scientists say. Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution, but a new study from Stanford University suggests that might not always be the case.

FAQ - How do I find a Census tract code for a specific street address?

How do I find a Census tract code for a specific street address?

The Census Bureau offers an Address Search tool in the American FactFinder that allows users to enter an address and then view each level of Census geography, including tract, in which the address is located.  The American FactFinder uses the address ranges in the Census Bureau’s MAF/TIGER database to geocode addresses.

If you are unable to locate your address using the American FactFinder tool, another option is the Federal Financial Institutions Examination Council’s (FFIEC) tool, which uses a commercial database to geocode.

New Strategy for Controlling Epidemics in Big Cities

submitted by Luis Kun

homelandsecuritynewswire.com - January 27, 2014

In a large city like Washington, D.C., with about 50,000 visitors on any given day who stay for just a few days, there is a constant influx of new people who are susceptible to infections. Further, they visit highly populated tourist destinations, where they come into contact with other visitors as well as residents. Disease can spread quickly.

Cities Mobilize to Help Those Threatened by Gentrification

PHILADELPHIA — Cities that have worked for years to attract young professionals who might have once moved to the suburbs are now experimenting with ways to protect a group long deemed expendable — working- and lower-middle class homeowners threatened by gentrification.

The initiatives, planned or underway in Boston, Philadelphia, Washington, Pittsburgh and other cities, are centered on reducing or freezing property taxes for such homeowners in an effort to promote neighborhood stability, preserve character and provide a dividend of sorts to those who have stayed through years of high crime, population loss and declining property values, officials say.

Newcomers, whose vitality is critical to cities, are hardly being turned away.

Aruba in the southern Caribbean has 107,000 people, a lot of wind and sun and, until very recently, one very big problem. Despite the trade winds and sunshine, it was spending more than 16% of its economy on importing 6,500 barrels of diesel fuel a day to generate electricity. People were furious at the tripling of energy prices in 10 years and the resulting spiralling costs of imported water and food.

Stem cells cultivated without using human or animal cells

medicalnewstoday.com - February 6th, 2014

Previously, stem cells have been cultivated using animal proteins or by growing them from other human cells. Both methods come with associated problems. But, according to a study published in the journal Applied Materials & Interfaces, researchers have now identified a new method for cultivating stem cells.

West Virginians Harvest Rainwater in Wake of Chem Spill

Some residents of the Kanawha Valley in West Virginia lost access to clean drinking water on January 9, when a coal-processing facility spilled roughly 10,000 gallons of crude MCHM—a chemical used to treat coal—into the Elk River and surrounding land. The spill affected the water supply for more than 300,000 people.

The quality of the water remains in question, but residents aren't satisfied with a choice between expensive bottled water from the store and possibly polluted water from the tap. Increasingly, they're going for a sustainable and self-sufficient alternative: rainwater harvesting.

This interactive graphic shows how each state can move to 100 percent renewable energy by 2050. See http://thesolutionsproject.org/infographic/.

Mark Jacobson and his colleagues have created a 50-state roadmap for replacing coal, oil and natural gas with wind, water and solar energy.

stanford.edu - by Mark Shwartz - February 26, 2014

Stanford University scientist Mark Jacobson has developed a 50-state roadmap for transforming the United States from dependence on fossil fuels to 100 percent renewable energy by 2050. He unveiled the plan at the annual meeting of the American Association for the Advancement of Science in Chicago.

"Drastic problems require drastic and immediate solutions," said Jacobson, a professor of civil and environmental engineering. "Our new roadmap is designed to provide each state a first step toward a renewable future."

Social Media Lie Detector Sorts Fact from Rumor

The new system will aim to tell fact from fiction

news.discovery.com - by Alyssa Danigelis - February 21, 2014

Internet trolls and anarchists beware: European computer scientists are working on a system to separate fact from false rumor online.

If all goes well, the lie-detector will be able to categorize an online rumor as speculation, controversy, misinformation or disinformation. Then it will automatically assess the source, zeroing in on factors like automated bots and newly created Twitter accounts, according to the press release. Finally it will display the results on a dashboard, making the truth easier to spot.
