  • What rural Alaska can teach the world about renewable energy

    I flew into Unalakleet, Alaska, on a late fall day. With about 700 people, Unalakleet is large by rural Alaska standards and serves as a regional hub. The village is located on a sandy spit of land where a clear river meets the turbid water of the Bering Sea. Out the plane window the sun shone bright, glittering off the wind-tossed whitecaps of the sea. To the east, the rolling Nulato Hills, clad ...

  • Small Wind Turbines tested: “Fortis Montana best performance”

    The market for commercial wind turbines is maturing even as they get bigger and bigger, but the market for small wind turbines is quite young, with some people comparing it to the car industry early in the 19th century. Although some manufacturers have been in the business for over two decades, most suppliers are from this millennium. And that shows. As in most immature markets, there are ...

  • A small island in the Indian Ocean offers big lessons on clean power

    The Indonesian island Sumba is working to provide 100% renewable electricity to all 650,000 residents by 2025. As the sun sets on the small Indonesian island of Sumba, Danga Beru Haba begins weaving under the glow of a single incandescent lightbulb, the only one in her home. Although she is tired from working dawn to dusk in the fields surrounding her village of ...

  • UK offshore load factors accelerate on tech breakthroughs: 10-year study

    UK offshore load factors accelerate on tech breakthroughs: 10-year study The Crown Estate’s Offshore Wind Operational report 2015 shows there has been a gradual increase in the load factor for the UK fleet since 2004 on the back of more productive wind turbines, wind farms being built at windier sites and improved plant availability. The Crown Estate manages UK sovereign ...

  • Micropower system modeling with Homer

    The HOMER Micropower Optimization Model is a computer model developed by the U.S. National Renewable Energy Laboratory (NREL) to assist in the design of micropower systems and to facilitate the comparison of power generation technologies across a wide range of applications. HOMER models a power system's physical behavior and its life-cycle cost, which is the total cost of installing and operating ...

  • US plant shutdowns, grid focus drive storage growth: Greensmith CEO

    Power plant closures and hiking transmission costs are driving up US utilities’ investment in renewable energy storage, John Jung, CEO of Greensmith, an energy storage services firm, told Wind Energy Update. Some 60 GW of US coal-fired capacity is set to close between 2012 and 2020, according to the EIA. Nuclear plant lifespans will end and the US plans $180bn in planned transmission ...

  • Green Futures Rely on Strong Magnets

    When lodestone was first discovered before the 1800s people were amazed at this rock that got attracted to itself. They noticed that it pointed to a specific direction every time it was suspended freely or was placed on water. This led to its use in the first compass to give sailors direction as they went for expeditions at sea. Further investigations led to the production of stronger ...

  • Inclusion of biodiesel and PV modules in a wind diesel hybrid system supplying electrical loads on a small farm

    The growing interest in biofuels is a consequence of the need to reduce operating costs of energy systems and the need to reduce emissions of greenhouse gases. The same applies to PV modules, comprising a solution environmentally desirable for power generation. This paper presents a study on the inclusion of biodiesel and PV modules in a system already in operation on a small farm in southern ...

  • Influence of exogenous and endogenous factors on the exergy analysis of 3–column array wind farm

    Influence of exogenous and endogenous factors on the exergy analysis of 3 column array wind farm for two different layouts are highlighted in this paper. Nine turbines were placed in two different layouts to analyse the influence of exogenous factors such as wind velocity, wind direction, wind distribution and distance between turbines. Endogenous factors considered were diameter of rotor, hub ...

  • 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 ...

  • Iowa and South Dakota Approach 25 Percent Electricity from Wind in 2012: Unprecedented Contribution of Wind Power in U.S. Midwest

    Defying conventional wisdom about the limits of wind power, in 2012 both Iowa and South Dakota generated close to one quarter of their electricity from wind farms. Wind power accounted for at least 10 percent of electricity generation in seven other states. Across the United States, wind power continues to strengthen its case as a serious energy source. ...

  • Small wind turbine emulator with armature controlled separately excited DC motor via analogue electronic circuit

    In this paper, a small wind turbine emulator (WTE) using separately excited DC motor is modelled, designed, simulated, implemented and tested. A 1 HP separately excited DC motor is used to emulate the characteristics of the rotor of small wind turbine. The DC motor is driven by a thyristor bridge with closed–loop cascaded PI controller for armature control. A separately excited DC generator with ...
