When the temperature drops, the turbine stops, and needs electric heat! by The Elephant's Child

Like many states, Minnesota has invested in alternative energy.  It’s the in thing to do.  The state has spent $3.3 million on eleven wind turbines, but in an economy where everyone seems to speak in billions and trillions, that doesn’t seem like news.

But it seems the turbines don’t work in cold weather.  The special hydraulic fluid used for colder temperatures was used in the turbines, but it’s not working, so neither are the turbines.

There is a plan to heat the fluid, but officials must find a contractor to do the work.

So they need heaters to warm the hydraulic fluid.  How will the heaters work?  They will have to use either electricity or natural gas at each turbine to keep the mechanism lubricated.  That reduces the net energy gain from each turbine, depending on how much heating the turbine fluid needs, to stop congealing in the winter.  Minnesota winters last anywhere from four to six months, so that makes the wind farm fairly inefficient as an energy source.

As we were saying, you simply can’t rely on what the turbine salesmen are claiming about the efficiency of wind power.  Sometimes the wind blows, sometimes it doesn’t.  It is simply not reliable enough to be a primary energy source. But it is “Green” so there are brownie points involved.
