Lets Learn About Small Wind.

Glas Éireann Solutions (GES) is an ESCO (energy service company) based in Limerick, Ireland, serving the public and private sector throughout Ireland. Our team has expertise providing economical green energy solutions to the agricultural, industrial, hospitality, and transport industries. We strive to be the market leader in providing the broadest range of energy solutions, some of which can be found here, and also include design and implementation of energy savings projects, retrofit, energy conservation, maintenance and innovative financing options that improve business efficiency without any expensive capital outlays.

Today however, lets concentrate on one of these energy saving methods, and try to answer some frequently asked questions - Small Wind.

  • What is Small Wind?
    • A small wind turbine is a wind turbine used for microgeneration, as opposed to large commercial wind turbines, such as those found in wind farms, with greater individual power output.
  • How does it work?
    • Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.
  • What is wind speed needed for a wind turbine?
    • 8 kph (2 m/s) minimum is required to start rotating most small wind turbines. 12.6 kph (3.5 m/s) is the typical cut-in speed, when a small turbine starts generating power. 36–54 kph (10–15 m/s) produces maximum generation power. At 90 kph (25 m/s) maximum, the turbine is stopped or braked (cut-out speed).
  • Why do they have 3 blades?
    • This is because when one blade is in the horizontal position, its resistance to the yaw force is counter-balanced by the two other blades. So, a three-bladed turbinerepresents the best combination of high rotational speed and minimum stress.
  • Are wind turbines really effective?
    • Wind power is cost-effective. It is one of the lowest-cost renewable energytechnologies available today, with power prices offered by newly built wind farmsaveraging 2 cents per kilowatt-hour, depending on the wind resource and the particular project's financing.
  • How does a wind turbine help the environment?
    • Wind Turbines are used to convert wind, a renewable source of energy to electricity. They are thus a better choice than conventional power plants that use non-renewable sources, emit air-pollutants and greenhouse gases.
  • How are wind turbines made?
    • Rotor and rotor blades - The rotor along with the rotor blades converts wind energy into rotary mechanical movement. Presently, the three-blade horizontal axis rotor is the most popular. The rotor blades are mainly made of reinforced carbon-fibre plastics or glass fibre.
  • How much energy is produced by a wind turbine?
    • The output of a wind turbine depends on the turbine's size and the wind's speed through the rotor. An average onshore wind turbine with a capacity of 2.5–3 MW can produce more than 6 million kWh in a year – enough to supply 1,500 average EU households with electricity.
  • What is wind energy used for?
    • Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes, businesses, schools, and the like.
  • How much do they cost?
    • The cost varies significantly on the size of the wind turbine and the output required. We at Glas Éireann Solutions will assess and guarantee savings for your business, put a proposal together, conduct all installations and maintenance, and it won't cost you a single cent in capital outlay.
