Ireland changes the rules for microgeneration - 0 views

  •  
    The measures introduced by Energy Minister Eamon Ryan yesterday include a guaranteed feed-in tariff of 19 cents per kilowatt hour of electricity for the first 4000 microgeneration installations over the next three years.

    "Our vision is of a UK where homes are energy efficient and local power generation from renewable sources is the norm. Our purpose is to make it easy for people to get the information they need to invest in renewable energy (or decide it is not right for their home)."

Is micro (home) generation of electricity good for the environment? - 0 views

  • What if I told you that often installing microgeneration equipment does not help the environment?
  • In times of oversupply from renewables, it would be far preferable to be ramping up consumption of energy using moveable loads, rather than shutting down production from renewables.

Technology Review: A Design for Cheaper Wind Power - 0 views

  • FloDesign Wind Turbine, a spin-off from the aerospace company FloDesign based in Wilbraham, MA, has developed a wind turbine that could generate electricity at half the cost of conventional turbines. The company recently raised $6 million in its first round of venture financing and has announced partnerships with wind-farm developers. The company's design, which draws on technology developed for jet engines, circumvents a fundamental limit to conventional wind turbines. Typically, as wind approaches a turbine, almost half of the air is forced around the blades rather than through them, and the energy in that deflected wind is lost. At best, traditional wind turbines capture only 59.3 percent of the energy in wind, a value called the Betz limit.

Small-scale wind energy | Carbon Trust - 0 views

  • Small-scale wind energy (wind turbines <50kW rated capacity) is receiving increasing interest as one of a number of microgeneration technologies with potential to reduce carbon emissions. Recent years have seen new products being made available on the UK market, which a survey by the British Wind Energy Association (BWEA) suggests is growing quickly.
    • Peter Fleming
       
      Yes, but I heard that the energy generation of wind turbines was proportional to the square of the diameter. Therefore if you just half the diameter of a large one you quarter the energy captured.
  • However, the overall potential of small-scale wind energy to reduce carbon emissions, and the conditions under which maximum carbon reductions can be made, have not been entirely clear.

George Monbiot: B&Q's bluster on micro-wind power runs out of puff | Environment | guar... - 0 views

    B&Q's decision to face facts and withdraw its useless micro wind-turbines is baffling only because it has taken so long

Apeldoorn first to get the central heating boiler of the future - 0 views

  • The first of 200 micro-CHP boilers was today put into service in the Apeldoorn suburb of Woudhuis as part of a large-scale field trial. Annelies van der Kolk, member of the Gelderland provincial executive responsible for climate and environment, today set the trial period officially in motion. "I am proud of this result of innovation and cooperation by so many parties. It's one of the ways we are working together towards a sustainable Gelderland", says Annelies van der Kolk.

Study: Microwind turbines a tough sell in Mass. | Green Tech - CNET News - 0 views

  •  
    The Massachusetts Renewable Energy Trust commissioned a study last year to review electricity output from 21 small wind turbines in the state and the results were surprising: the data showed that the estimated production was about three times higher than the turbines' actual production.

Smart metering gains ground in France and UK | Energy Efficiency News - 0 views

  • A consortium of four electricity distributors is rolling out Echelon’s smart meter to 90,000 homes in France.Echelon’s Networked Energy Services (NES) meters allow the amount of electricity produced as well as that consumed to be measured. This allows the meters to be used with renewable microgeneration technologies as well.

UK gives homeowners green light for solar power | Environment | Reuters - 0 views

  • From April 6, all homeowners in Britain will be free to install microgeneration equipment like solar panels without getting planning permission for them, as the government tries to cut climate warming gases emitted from coal and gas fired power plants in order to supply electricity.

"Micro-generation technologies are the wave of the future" - 2 views

  • It's not enough to just find the very best solid oxide fuel cell distributed generation system, of which there are actually many to choose from already, which some journalists appear to have forgotten this week.  It's not about the best SOFC technology, it's about supplying kilowatt-hours (or joules of energy, or liters of clean water, etc.) at the right price and in the right way for each application.  And there are often many different ways to supply these commodities.
