The Cost of Energy » Stats alert: Top green power users in the US - 0 views

  •  
    The US EPA has released their latest list of the top consumers of green power in the US:

    The Green Power Partnership works with a wide variety of leading organizations - from Fortune 500 companies to local, state and federal governments, and a growing number of colleges and universities. The following Top Partner Rankings highlight the annual green power purchases of leading organizations within the United States and across individual industry sectors.

The Cost of Energy» Map alert: NPR's US electricity maps - 0 views

  •  
    Hot on the heels of the release of the NRDC's renewable energy map, we have another piece of first-rate energy geek eye candy: NPR: Power Hungry: Visualizing The U.S. Electric Grid.

    This map will let you check different sources (with separate maps for wind and solar, in addition to traditional sources), and toggle transmission lines and other features on and off.

    My only gripe is that you can't zoom the maps, which in some cases makes it a challenge to click on the circle for a particular power plant.

Peak Energy: Energy 101: Where Does Our Power Come From ? - 0 views

  •  
    Inhabitat is doing a "Energy 101" series to explain why smart grids are necessary - Energy 101: Where Does Our Power Come From ?.

    Today we're excited to announce the launch of our new Energy 101 series,. in which we'll be exploring the future-forward technologies that stand to upgrade our grids, reduce our energy footprint, and slow the speed of global warming. Unless you have been living in a cave for the past few years, you've probably heard terms like "energy conservation", "off-grid energy", and "smart grid" tossed around. But before getting into the nitty-gritty of transitioning to renewable energy, we should stop and examine where exactly our power comes from now.

    Unless you derive all your power from on-site renewable energy sources like solar panels or wind turbines, chances are that you're connected to the power grid, a vast network that delivers electricity from suppliers to consumers. Right now, most energy on the grid comes from generating plants. These plants still usually get power from traditional sources like coal, nuclear, and hydroelectric dams. But as concerns over carbon emissions, safety, and long term sustainability of these sources grow, electrical utilities have begun to switch over to renewable energy sources.

On Call Street Lights: Light By Phone Saves Energy and City Budgets : TreeHugger - 0 views

  •  
    A trend is spreading through small towns across Germany. Tight budgets have forced hard decisions, including turning the lights out at night. No one is on the streets at night anyway, so why pay for the electricity to run the street lights? But residents have revolted. They fear an uptick in crime, or simply for their safety while stumbling through the dark streets to walk the dog or return from a late night out. Proving necessity is the mother of invention, a handful of clever solutions are being implemented; some with interesting consequences.

    The solution seems to have started in the small town of Morgenröthe-Rautenkranz in the Erzegebirge. Over one and a half years ago, the 900 citizens of Morgenröthe-Rautenkranz were plunged into darkness each night, but given the option to turn the lights on by mobile telephone. Older citizens were concerned about their ability to master this new technology, but practice makes perfect. The first two weeks of the program, the lights remained on almost all night long as residents remained awake late for an opportunity to test the new system! But now the lights stay off except when needed. The town saves 4000 euros ($5300) per year. According to the Berliner Morgenpost daily newspaper, Morgenröthe-Rautenkranz is the inspiration for 4300 person community of Groß Pankow, the most recent community to consider on-call streetlight.

Peak Energy: Electricity from Waste Heat - 0 views

  •  
    Technology Review has an article on a new system from Ener-G-Rotors which harvests energy from low temperature waste heat - Electricity from Waste Heat.

    Factories, data centers, power plants--even your clothes dryer--throw off waste heat that could be a useful source of energy. But most existing heat-harvesting technologies are efficient only at temperatures above 150 °C, and much waste heat just isn't that hot. Now Ener-G-Rotors, based in Schenectady, NY, is developing technology that can use heat between 65 and 150 °C.

Electricity 2.0: Using the Lessons of the Web to Improve Our Energy Networks - the video! - 0 views

  •  
    Many people have been asking me if there is a video of the presentation I gave at this year's O'Reilly Web 2.0 Expo available anywhere.

    I asked the organisers but they said they hadn't recorded it.

    Then my good friend Andrea Vascellari came to the rescue. I knew he had attended the presentation but I was unaware that he recorded it.

    He published the video above this afternoon so for all those who were interested, here you go…

Electricity: An Astonishing Abundance - 0 views

  •  
    Our story of energy begins when humans discovered the secret of fire. We burned wood and brush to protect ourselves from predators, cook food, and, later, to survive the ice age. In 12th-century Europe, with the forests fast disappearing, we started burning the strange black stones we called coal. Later, we used coal to produce steam, launching the Industrial Revolution.

    Demonstration Projects Aim at 15 Percent Reduction of U.S. Peak Load Electricity Demand

    Washington, DC- U.S. Department of Energy (DOE) Assistant Secretary for Electricity Delivery and Energy Reliability Kevin Kolevar today announced the Department's plans to invest up to $50 million over five years (Fiscal Years 2008 - 2012), subject to appropriations from Congress, in nine demonstration projects competitively selected to increase efficiency in the nation's electricity grid.
