Wind Turbine hit by lightning

#windfarm #renewable #green

ONE of Verve Energy’s wind turbines at the Esperance Wind Farm was hit by lightning last Saturday week, shredding the blade and making the turbine inoperative.

Technicians were at the site last Friday doing routine maintenance on other turbines and say that the damaged turbine has been made safe for the time being.

“We’ve been up there and cut away what debris we could and there isn’t any danger,” Verve contractor, Brian Helenius from Power Technics said.

“The blades have to come from Denmark in Europe and then they have to be finely balanced with one another, so there is a lot of work involved in replacing it.
“Each blade has a serial number and a weighting so when the three are installed together, they have to be finely tuned.”

How “green” is it to have a replacement blade come from Denmark to Washingon state?

Wind is NOT 24/7. No wind. No power.

UPDATE: For more information on wind farms and lightning, read this article (PDF). Lightning doesn't have to be a direct hit to damage a turbine. Electrical parts damaged by lightning may not be covered by manufacturerer warranty.

  1. You're a dumb ass. I'd say the pollution that comes from shipping a wind turbine by ship and then most likely train is a hell of a lot greener than burning coal for the same amount of electricity that it will generate. Wind farms are built strategically in areas with a good, consistent amount of wind. They don't need to turn 24/7 to generate electricity, and solar doesn't need to have sun 24/7 to generate enough electricity. They electricity they generate is stored, so it doesn't matter if there isn't wind for a day or sun at night. Do some freaking research. Maybe go to a house that is powered entirely by solar or wind power and then tell the people that live there that they can't turn on their lights at night because there's no sun so they don't have electricity.

  2. Would you believe an official of the San Diego Gas & Electric Co.?

    “When a cloud goes over a solar farm or the wind dies down, a {natural} gas plant has to kick it up a notch to make up the difference.”

    Home systems can store excess energy for times when the wind isn't blowing or at night for solar.
    I have researched it and commercial storage seems to be in the experimental stage and is currently not in wide use.
