  • Fact Sheet: U.S. electricity markets increasingly favor alternatives to coal

    The U.S. electric power system is gradually shifting toward cleaner forms of generation. One sign of this transition is the declining use of coal for electric power production. In 2011, use of coal for U.S. power generation dropped to its lowest level in more than a decade, according to the federal government’s independent U.S. Energy Information Administration (EIA). In fact, the EIA ...

  • Fuel reduction potential of energy management for vehicular electric power systems

    In the near future a significant increase in electric power consumption in vehicles is to be expected. To limit the associated increase in fuel consumption and exhaust emissions, smart strategies for the generation, storage/retrieval, distribution and consumption of the electric power can be used. This paper considers a vehicle configuration with a conventional drive train. Two energy management ...

  • Wind energy and system security – the grid connection moratorium in Ireland

    This examines the interaction between technical challenges and policy choices that are made regarding wind power, and uses the grid connection moratorium in Ireland as a case study. While total installed wind capacity in Ireland is low compared with Germany, Spain and Denmark, wind power penetration is higher in the Irish system than in either the British, UCTE or NORDEL systems. In December 2003 ...

  • Case study - Coater replaces old oxidizers With energy efficient systems

    Overview Emission control and the operating costs associated with meeting environmental regulations were nothing new for the Coated Products Division of Brady Corp. The company has been manufacturing coated films for nearly 60 years, demonstrating over that time a commitment to pollution prevention and emission reduction programs. But these considerations were magnified ...

  • Haiti Sustainable Energy Roadmap. Harnessing Domestic Energy Resources to Build a Reliable, Affordable, and Climate - Compatible Electricity System

    Haiti’s electricity sector stands at a crossroads. Haiti depends on imported petroleum for 85% of its electricity generation, diverting 7 percent of its annual gross domestic product to importing fuel. Still, only 25% of the Haitian population has regular access to electricity, bringing barriers to advances in economic opportunity, health, education, and social equality. Yet, according to ...

  • Biofuel - Energy Supplier of the Future?

    Biofuel like biodiesel, plant oil, ethanol, bio methane or the synthetic biomass- to- liquid (BtL)- fuels everyone is talking about them. They are at present the only renewable alternative in the mobility sector and already today make up 6.1 % of the fuel consumption in Germany. However, in the past months and years biofuels had the reputation to generate a social- und environmental dilemma. ...

  • The Energy Revolution is Here

    We live in an exciting time. Yes, glaciers are melting, sea levels are rising, and in my new home in the Western United States, earlier snowmelts, longer summers, and hotter temperatures have made wildfires 400 percent more frequent. And yet, there are encouraging signs we are in the midst of an energy revolution that is sure to transform our climate, our economy, and our lives for the better. ...

  • On the application of miniSoDAR technology to wind energy

    Introduction In the late 1990’s wind turbines with nacelle heights exceeding 60 meters were introduced to the wind energy community. Initially, wind prospecting and siting studies continued to use 50-meter wind towers and extrapolate the measurement to the nacelle heights. It was quickly determined that this approach was not sufficient for the placement of these tall turbines. The next ...
