First Town In US To Become 100% Wind Powered

gundar99 writes "Rock Port Missouri, population 1,300, is the first 100% wind-powered city in the US. Loess Hill Wind Farm, with four 1.25-MW wind turbines, is estimated to generate 16 gigawatt hours (16 million kilowatt hours) of electricity annually. 13 gigawatt hours of electricity have historically been consumed annually by the residents and businesses of this town."

      That's pretty much nonsense, sorry.

      AC is horrible over (really) long distances, because long lines act as inductivities, which increase the impedance (complex resistance) for AC, but not for DC.

      AC has a historic advantage over DC because it is trivial to convert AC to a different voltage (using a transformer), whereas it is fairly complicated to do that to DC. Higher voltages decrease the line losses since less current has to flow to deliver the same amount of power. That makes AC better in cases where you just don't have the technology to build an efficient DC voltage converter, or for short- to medium-distance distribution where you don't want to deal with the additional complexity or the efficiency of a transformer beats the efficiency of the DC voltage converter.

      If you want to send power over _really_ long distances (1000 km and more), AC is a poor choice. High-voltage DC is used instead.

      I knew there would be a post like this. This always comes up when people discuss wind and solar. First, if they were not on the grid they could use "peak storage". There are a number of ways to do that. In areas where water and elevation are available, you can pump water back up a hill into a holding pond and re-cycle it through a turbine--augmented hydro power. Other methods of peak storage include: flywheels, batteries, and even compressed air pumped into abandoned mines that have been properly sealed to hold in the pressure. Choice of method depends on a variety of factors of course.

      Now, since they are connected to the grid, the peak storage issue isn't very important. They just feed the grid when they have excess, and draw from the grid when they don't. Therefore, they are actually *over* 100% since they are expected to feed the grid more often than they draw from it. If everybody did what they did, then peak storage would be required because it is possible for calm conditions to persist over fairly wide areas--perhaps wide enough to make transmission impractical. The only difference here is that they are using the grid as a virtual peak storage system.

      When wind power is sent to "town B", they can idle one of their fossil-fuel generators. The fuel un-burned by said generator is another way to account for peak storage.

      Using the grid as peak storage just makes better econonmic sense than building your own peak storage and declaring independance like some kind of cult or something.

      Each source type has two flags: reliable, and fueled; and one valuation: emission output.

Then throw in the fact with steam power that you really need to use fuel, because you want to maximize uptime, since powering down can cool the plant down, and thermal transients can do bad things wear and tear wise.

      Also what's the effect of a worst case catastrophic failure in a windfarm (thrown blades or a tower collapse) in one of many parallel turbines vs. a catastrophic failure (something going boom) in a steam based powerplant?

Unless you are going to argue that nuclear power is unacceptable (which typically involves some serious truth-bending with regards to putting things in perspective ) wind power simply isn't worthwhile.

    I think the main problem is people don't understand the scale of things.

In comparison a single nuclear power plant can produce between 500MWe - 3000MWe with a capacity factor close to 90%, and in some plants a single reactor can produce more than 1000MWe, and then there is some 2000MW of spill heat you could use for district heating on top of that. Thus if you are planning on replacing nuclear generating capacity in a country such as France, you will literally need hundreds and thousands of wind turbines at the very least, and likely millions or tens of millions if you are to guarantee an adequate supply around the year. Now keep in mind, this is not "one on each rooftop" millions, this is giant offshore, interferes with marine life and shipping routes millions. This is before you start considering the energy needed to replace petroleum in our cars, oil used for heating etc...

    But wait, they may have a calm day, or a _storm_. During storms you don't make more power, you align the blades so the turbine doesn't spin. So someone else has to have the capacity to produce an extra 8 MW for them, for those cases.

    The point is that someone still has to be able to cover the peak power, so just as many power plants have to be built as before. Only now you have to keep some of them idle at peak time, so you don't recoup your investment as quickly.

    The total power produced maths are also a bit mis-leading. They use more power at peak, they give some power back when noone needs it. The problem isn't producing enough energy at 1 AM, the problem is producing enough energy at peak times. That's when those brownouts some years ago happened. The rush to build more power plants, and dealing with NIMBY syndrome, is to be able to supply the whole use at peak hours, not at night.

    Because wind can and will occasionally fail you, someone has to build the same capacity again as some other kind of power. Only, again, keep it idle a bunch of the time so they won't get their money back as fast.

    Essentially, they just passed someone else the cost of building the peak storage for them. They get their peak storage (and more importantly: backup power) all right, only now "Town B" from your example is the one who gets the bill for it.

This decay produces hydrogen sulphide (generally nasty) and methane (a greenhouse gas IIRC 400x stronger than CO2). This is the origin of concerns about how much greenhouse gas production that hydropower offsets.

    Then, when the water level dives down, you kill the anaerobic systems, leaving a barren coastline (both just above and just below the waterline at the coast) which is less hospitable to fish and terrestrial animals whose life is based around this environment.

    Yes, you use someone else's share at peak time (i.e., at the time when it matters), and give it back to them at night, when they don't need it.

Because a power company usually _has_ to buy energy that individual users pump back, whether they want it or not.)

The part about the spinning reserve is true but they don't give all the information. The whole plant doesn't go on spinning reserve when the wind plant makes energy. Only part of it does. Plus it doesn't use as much fossil fuel in this mode as otherwise. I don't have the hard and fast numbers but I'm willing to bet that wind power cuts down on fossil fuel consumption. It's kind of like how solar power can be generated at a home and sold back to the grid. Of course solar generates power during peak times but solar also doesn't work well everywhere.

    I think the point of misunderstanding is that you are treating this solution in isolation while everyone else is thinking in terms of a fabric of similar plants scattered across the country. They don't all have to be wind farms, btw. Some can be solar, some nuclear, etc.

    The point is, if you're on the grid, you share capacity with everyone else. Peak usage will vary by timezone, so if the grid is large enough, no problem from having to build too much overcapacity in any single plant.
