turbine

Examples of turbine in the following topics:

• Wind power

  • Today, Denmark derives over 20% of its electricity needs from wind turbines; Germany gets over 10% of its electricity from the wind; and every year Spain installs over 2,000 megawatts of wind turbine generators.
  • In 2012, American wind turbines pumped out 50 gigawatts of energy (enough to power 15 million homes) and every year the number grows (as do the total number of jobs wind turbines create).
  • Wind turbines come in a variety of shapes, sizes and configurations, and usually last around 20 years or longer if they're maintained correctly.
  • Size-wise, wind turbines can range from huge multi-megawatt, 11-storey towers (which power thousands of homes), to modest 1 megawatt turbines that can power 350 homes, or smaller 1–10 kilowatt roof-mounted turbines which are purchased from specialized retailers and can power a house or business.
  • A model created by the National Renewable Energy Laboratory (USA), for example, found that several locally owned wind turbine projects in Iowa generated significantly higher economic impact levels than projects of equal capacity owned by other investors.

• Is wind power right for your business?

  • Some turbines are designed to operate at low wind speeds while others can withstand powerful gusts.
  • Will the noise, movement and aesthetics of the proposed wind turbine be an issue for the local community?
  • Will the turbulence (which is created by every wind turbine) effect nearby structures?
  • Keep in mind that not all wind turbine stories have happy endings.
  • For more information on turbines, visit the American Wind Energy Association website at www.awea.org.

• Are solar voltaics right for your business?

  • Note that energy from the sun can also heat water (and buildings) as well as drive steam turbines.
  • For example, calculations for concentrated solar power, which uses mirrors to concentrate sunlight onto a fluid-filled container to produce steam that drives a turbine, is cost-equivalent to oil priced at $50 per barrel (before payback) – or as low as $20 per barrel (before payback) when the technology is scaled up.

• Electric Generators

  • Possible sources of mechanical energy include: a reciprocating or turbine steam engine , water falling through a turbine or waterwheel, an internal combustion engine, a wind turbine, a hand crank, compressed air, or any other source of mechanical energy.

• Micro-hydro power stations

  • The turbines they house are small so they blend into natural settings while producing enough electricity to power several hundred homes or businesses.

• Tides

  • Energy of tides can be extracted by two means: inserting a water turbine into a tidal current, or building ponds that release/admit water through a turbine.
  • In the first case, the energy amount is entirely determined by the timing and tidal current magnitude, but the best currents may be unavailable because the turbines would obstruct ships.
  • While some generation is possible for most of the tidal cycle, in practice, turbines lose efficiency at lower operating rates.
  • Tidal energy generator that works like a wind turbine, but with the ocean currents providing the energy.
  • The circle in the middle is the turbine.

• Introduction to Macro Advantages of Micro-power

  • In Aberdeen, Scotland, the Cults Primary School set up a 5 kilowatt wind turbine in May of 2007 that not only reduced its electricity bill, but also cut its annual carbon emissions by 5,633 kilos.
  • And across the American state of Iowa, wind turbines now power ten schools either partially or completely.
  • The 4,924 m2 elementary school in Spirit Lake, Iowa, for example, installed a 250 kilowatt wind turbine that provides an average of 350,000 kilowatt-hours of electricity per year.

• New Sources of Energy

  • Both involve harnessing the power of naturally occurring events-- sunlight and wind-- and converting them into electric power through solar panels or wind turbines .
  • Critics of these sources often cite aesthetic concerns-- for example, that the panels of turbine farms block site-lines or alter landscape and architecture.
  • These wind turbines exemplify one type of a new and alternative energy source.

• Modern Architecture: Form Follows Function

  • The AEG Turbinenfabrik ("turbine factory"), 1909, designed by Peter Behrens, illustrating the combination of industry and design.

• Additional examples

  • Other changes being considered in the UK would make it easier for companies to install green technologies like solar panels and wind turbines.
  • At the time this was proposed, most businesses had to go through a lengthy planning application process (from 8 to 16 weeks) and pay the equivalent of $3,000 if they want to install a solar panel or small wind turbine.
