Megadams Are Dismal Investments By Blake Schmidt March 13, 2014 Photograph by Taylor Weidman/Zuma Press Indigenous Munduruku men at the quarry site for Belo Monte It’s hard to overstate the massive proportions of Belo Monte. When completed, it will be the world’s third-largest dam. Set in the heart of the Brazilian Amazon, it will funnel water through 18 turbines, each with the diameter of the Space Shuttle. When the last one is switched on in 2019, Belo Monte will have a capacity of 11,233 megawatts—enough to supply power to 40 percent of Brazil’s households. Construction crews, which began work in 2011, will have to dig up almost twice as much dirt as was removed to build China’s Three Gorges Dam, and truck in enough steel to build 16 Eiffel Towers, according to the dam’s developers. About 26,000 laborers toil in shifts around the clock. Massive is a word that also applies to the hydropower project’s price. Norte Energia, the consortium awarded a 35-year concession [...]

NEWS via FCW.com: Why Maps Matter

Why maps matter By Frank Konkel Mar 17, 2014 People used to use maps so they wouldn’t get lost. But in recent years, access to the Global Positioning System and the proliferation of mobile technology have made paper-based maps almost irrelevant. Unless you’re in uncharted territory, it’s hard to get lost anymore. Basic geography is as easy as inputting an address and letting your mobile phone tell you how to get there. And as mapping technology advances, it allows for far more than foolproof directions. Federal agencies now use geospatial data, geo-analytics and multi-layered maps for myriad purposes, including gathering intelligence, predicting disease outbreaks and sharing data pools with the public. The allure of mapping lies in its intuitiveness. Even simple “dots on a map can be a powerful way to see trends in data,” said Josh Campbell, geographic information system architect for the Humanitarian Information Unit at the State Department. “Maps [...]

Crimea: Economic fallout of a ‘yes’ vote By Alanna Petroff and Mark Thompson  @CNNMoney March 15, 2014: 7:54 AM ET Crimea is voting on Sunday in a referendum to decide if the region should break from Ukraine and join Russia.  LONDON (CNNMoney) The Ukrainian region of Crimea votes Sunday on whether to join Russia, a move that could tip Europe back into a Cold War with its powerful eastern neighbor. The West has called the vote illegal, saying Russian military activity in Crimea violates Ukraine’s sovereignty and will influence the outcome of the referendum. U.S. and European leaders say Russia will pay a price for annexing Crimea, and German Chancellor Angela Merkel has warned of a potential “catastrophe.” Related: Live coverage of the crisis in Ukraine If, as expected, Crimeans choose Russia over Ukraine, the fallout could ultimately affect economic growth, trade, investment and energy supplies.

These Maps Show Which Areas Of The Country Have The Biggest Carbon Footprints KELLY DICKERSON YESTERDAY AT 10:01 AM    19 It’s no secret that the U.S. is one of the biggest carbon emitters around. Households in the U.S. alone are responsible for 20% of greenhouse gas emissions, even though they account for just over 4% of the global population. But which areas in the U.S. are contributing the most? These interactive maps from the University of California, Berkeley show where the U.S. has the biggest carbon footprint. You can even calculate your city’s carbon footprint on their site. The carbon footprint measurement equals the total greenhouse gas emissions of the zip code in question. An area’s carbon footprint includes things like energy people use at home, energy used by businesses, and transportation. The biggest source of emissions depends on the area. For example, the suburbs have a higher percentage of emissions coming from individual vehicles than big cities do. [...]
