Wind power - Wikipedia, the free encyclopedia - 0 views

  • Sailboats and sailing ships have been using wind power for thousands of years, and architects have used wind-driven natural ventilation in buildings since similarly ancient times. The use of wind to provide mechanical power came somewhat later in antiquity. The windwheel of the Greek engineer Heron of Alexandria in the 1st century AD is the earliest known instance of using a wind-driven wheel to power a machine.[15][16].

  • Wind power generates electricity with... No air emissions No fuel to mine, transport, or store No cooling water No water pollution No wastes
  • Wind power can reduce pollution generated by fossil fuels such as coal, oil, and gas. A typical (750 kW) wind turbine provides enough power for 328 typical (non-electric heating) homes.

Tidal Power - 0 views

  • A dam-like structure is constructed across an estuary to trap a high tide of water and then let it pass through turbines to generate electricity. The water flow can generate electricity on the falling tide only, or on the falling and rising tide.

Visual Health Effects and Wind Turbines - The Society for Wind Vigilance - 0 views

  • In addition to noise pollution wind turbines also have visual burdens.
  • The health impact of visual burdens cannot be underestimated. An epidemiology study conducted by World Health Organization determined a “bad view out of window” increased the risk for depression by 40%. The same study also demonstrated disturbance by noise and sleep disturbance by noise increased the risk of depression 40%, and 100% respectively.
  • Wind turbines produce noise and visual burdens.

  • Scientific research confirms visuals impacts can adversely affect human health.
  • Wind turbine shadow flicker has the potential to induce photosensitive epilepsy seizures however the risk is low with large modern models and if proper planning is adhered to.
  • Wind turbine shadow flicker induced adverse human health effects include annoyance and/or stress.

How long has solar power been around and does it work? - An eNow Blog Article - 0 views

  • Solar PV (photovoltaic) was first discovered in 1839 by French scientist Edmond Becquerel. Over the next 100 years, there were other discoveries and inventions, including several discoveries by Albert Einstein, who received a Nobel Prize for his theories on the photovoltaic effect in 1921.

  • Negotiating power purchase agreements
  • In some states, where the electricity market has been deregulated, it is possible for the owner of a wind project to sell electricity directly to customers.  However, wind developers usually sell their electricity to electric utilities, which sell the electricity to customers. T his is usually done by negotiating a power purchase agreement, which is a contract requiring a utility to buy the electricity from a wind farm at a certain price over a certain period of time.  In some cases, an alternative arrangement is reached, in which the developer owns a share of the project long enough to mak

Infrastructure Battle: Renewable Tidal Energy vs. Telecommunications - 1 views

  • first tidal energy turbines
  • Both technologies require room for periodic ship-borne maintenance and repair access, with subsurface equipment which could impinge on the other facility if they're too close. And if one of the turbines breaks, as happened in 2010 with an earlier tidal turbine in the Bay of Fundy, PC Landing worries it could damage the nearby cable.

      This is a barrage system. Old tech.
  • Tidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into useful forms of power - mainly electricity.
  • Tidal power is extracted from the Earth's oceanic tides; tidal forces are periodic variations in gravitational attraction exerted by celestial bodies
  • ...2 more annotations...
  • Tidal power is the only technology that draws on energy inherent in the orbital characteristics of the Earth–Moon system, and to a lesser extent in the Earth–Sun system.
  • A tidal generator converts the energy of tidal flows into electricity. Greater tidal variation and higher tidal current velocities can dramatically increase the potential of a site for tidal electricity generation
  •  
    "tidal power has potential for future electricity generation. Tides are more predictable than wind energy and solar power."
