Why not more wind farms?

The best projections of the viability of intermittant renewables such as wind and solar are around 10-15% of the available power required. As others have said, it simply needs storage to get past that 15%. I love reneawables, but I acknowledge the problem.

I am glad to see that the price is dropping, but you did not say anything about storage. How can wind generation amount to more than a couple percent without some way to store the generated energy?
When the wind stops, is it not true that the generator draws energy from the grid to keep it warm, to spin it up as the wind increases, control circuits, etc.?
And with absolutely no energy storage there must be a coal /gas / ?? always running at 100% to pick up the complete load within a couple cycles of the wind dropping (or cloud crossing the sun).

Without storage solar and wind (even if the hardware were free) can never amount to more than 10% of energy needs. True, we could put up enough generators and solar panels to cover all demands... momentarily, but night comes when no panel works, and days come when even the Santa Ana winds don't blow.

We need storage to be a viable energy source.

I personally have no concerns about the appearance of modern windmills.  I don't understand why anybody would find them aesthetically intrusive.  I find their slow steady turns fascinating to watch!

Nadine, I like your point about visual appeal, or lack thereof. They are not fun to look at, although the ones in California I've seen tend to be located away from people.

You make a good point.  The ROI increases as more users/buyers invest.  I'm curious to know how the savings break down.  Has the initial cost dropped significantly or just operating?  Or, is long-term maintenance where the significant savings are?

Where the savings lie makes a difference for future investors. 

And, on a separate note, better design would help lesson the NIMBY factor.  Many communities still fight against wind farms as a visual blight.

Thanks, Rob, I agree about the good news. I find Jerry's input about what I expected, meaning, here's a technology that's not too expensive and it's been around a long time, but has not seen mass adoption. I think much of the reason has little to do with economics or technology, and more to do with psychology. It's the early adopters vs the mass market, as we've seen in many industries, most notably personal electronics. And not that many people live on farms or in the country anymore.

Nice article, Ann. That's quite impressive that wind is becoming competitive with gas and coal, especially with gas costs moving so low. This is very good news for alternative fuels.

Every time I drive through West Texas I wonder why we don't hear more about energy from wind farms - they are certainly out there and at least in Texas there are many more than a single turbine on the occasional farm...seems like these technologies have been around a long time (like solar) but are extremely slow moving. Some folks are fascinated by renewable energy and are determined to live "off the grid" but it just doesn't seem to be very popular in the mass market place...

               That WT's in small sizes are not really cost effective is because of greed, bad busines model or something else as I can make them for well under $1k/kw vs the $4k/kw most units cost now.

 

             Remember they perfected them in the 30's!!!!  Many of them are still running like the Jacob's and others.

 

             A 2k WT enough to run an eff home in an average wind site is more simple than a moped!!  So why are they so expensive?  I see a great market with large profits I'l be filling within a yr.  I can get 200% profit and still beat the others by 50% and even beat the Chinese. 

              I did go into production of some in the late 70's but the market wasn't there but it is now for a quality unit.

 

              Done right they need little maintaining other than a yrly check and new bearings every 3-5 yrs if designed and built right.

Thanks for your comment, Lou. Since most of the technical and manufacturing efforts for wind turbines right now appear to be aimed at making them in high volumes for wind farms, I'm not surprised that an individual agricultural farmer finds a single wind turbine impractical and payback is slow. It doesn't sound like the rental model is working very well for the individual farmer, but that model could, of course, be tweaked to make it more attractive and productive.

The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
