Flickr / CC BY 3.0 In the same way that solar panels are getting more efficient at converting sunlight into electricity, wind turbines are also getting better at harnessing the wind. There are two main levers that engineers can pull to squeeze out improvements: 1) Modifying the physical characteristics of the turbines, such as the shape of the blades, the components inside th..

© Skeptical Science Much ado is made about the phrase “the science is settled,” but to what does the phrase refer?? There are certainly a number of climate issues for which the scientific evidence is so conclusive and robust, they can reasonably be called “settled.”? For example, the fact that the increase in atmospheric CO2 levels is due to human emissions , the fact that the planet is warming ( as confi… Read the full story on TreeHugger US Dept Energy, EIA /Public Domain Texas faces now not only extraordinary dryness and fire danger, climate change has introduced the risk of gas production wells freezing up. Per a USDOE report: “Much colder than normal weather in the Southwestern United States in early February 2011 curtailed over 7 Bcf/d of natural gas production due to well freeze-offs (see chart); this disruption rivaled losses from major summer storms.” Imagine this on a much larger scale, in the rapidly-approaching era in which the nation will rely far more on natural gas … Read the full story on TreeHugger © Robert Fulton – Winter Field, Trees are the winner in the Landscape Photographer of the Year 2011 prize. There are now so many story lines that one can look at when examining the debate over the Keystone XL pipeline–among them pollution, greed, and a pervasive lack of leadership. The one that I gravitate toward is accountability The following piece, by Dana Nuccitelli, originally appeared in Skeptical Science . Now that the Berkeley Earth Surface Temperature (BEST) study results are in, and have confirmed the accuracy of the surface temperature record (see here and here ), those “skeptics” who spent years disputing the accuracy of the record despite all the evidence pointing to.. phault via Flickr / CC BY 2.0 Cape Wind was supposed to be the nation’s first offshore wind farm. It was announced over ten years ago, and after fighting through miles and miles of bureaucratic red tape, it was finally approved by the Department of the Interior earlier this year Jeremy Levine Design / CC BY 2.0 This post was written by J. Aquamantra /Promo image Four years ago I choked on Aquamantra , a bottled water that claimed that its water was special, that by using the basic principles of quantum theory “molecular structure of water was changed by a Zen Buddhist monk’s thought. Based on this premise, Aquamantra uses the design on its labels to affect the molecular structure of California natural spring water to make it more refreshing and wholesome to drink.”.. |
