Windmills on the horizon

Wind Power -- why settle for one plant when you can have two?
Of course, none of you will do this.
The picture with the article has a funny history.
It appeared a couple of years ago in the Deseret News with a caption, "Waiting for a stiff breeze". The article with it noted that Evanston, where the windmills in the picture are located, was socked is under an inversion. The windmills were not turning!
Like I said, you who like to be boosters of something you will not take the time to understand, can do more harm than good in our technically sophisticated world.
The Deseret News needs to take this to heart and stop embarrassing themselves.
Also, Anonymous @ 10:37:
The electricity from the wind farm goes directly into the grid along with all the power from coal/natural gas/etc. So every contribution of a kilowatt to the grid means one less kilowatt from coal or other non-renewables.
I'm proud of the Spanish Fork wind farm. The only disappointing thing about it is that because our country was so SLOW to get our renewable-energy act together that we don't have an industry set up. (Bush spends more in 1 month in Iraq than he's spent on renewable energy during his entire presidency.) As a result, nearly every nut and bolt of the wind farm had to be imported.
This isn't necessarily true.
1) Wind power can be used to create hydrogen that can be then sold to power future cars.
2) wind power can be used to compress air that can then be used during peak electrical use times, making it un-necessary to have natural gas fired plants to provide peak electricity.
Use your imagionation, Wind energy in the USA is in an infantcy, there are many great used it can be used for.
Idaho Power studied wind energy integration and found that it was more costly; this cost will be passed on to the consumer. Wind energy is 30 % efficient at best. Because of this many power generating plants cannot be taken off line. Denmark has 20 % of total power production coming from wind but 84 % was exported because of the variability of wind and costly nature of integration. France�s president has placed a moratorium on further wind turbines because of the destruction of France�s landscape.
The inconvenient reality is that our nation cannot replace fossil fuel energy with renewable energy. What happens when the subsidies expire or when it becomes too costly to integrate wind or when our politicians finally decide that more nuclear power plants need to come on line to meet our demands? Are we to have a graveyard landscape of these massive wind turbines lining our mountain ridges and forever change what we have loved of our environment?
Can we at some point convert from fossil fuels to wind energy to help decrease global warming? This can never be as wind energy is very inconsistent at best. According to the Federal Energy Information Agency, the actual experience of industrial wind power in the US is only 25 % of its capacity, or 500 kilowatts.
As a nation we need all sources wind, geothermal, nuclear if we are ever going to not be so dependent on foreign sources.
Lets get working.
While, as an engineer, I recognize the weaknesses in wind energy, I also think the most promising scenario for integrating wind produced energy onto the grid is to couple it with nuclear power plants to provide the baseload.
RE: Grimble: Besides the massive subsidies wind power is already receiving, the props needed to make wind assessable for daily use, WHEN WANTED, will make it much more expensive than other sources.
A Deseret News article on the Spanish Fork wind projects noted this wind power would sell for 3.8 cents per kWh whole the power from a totally flexible Payson, gas fired power plant would sell for 4.5 cents per kWh. However, remember wind-power's massive subsidies.
As I said earlier, try educating yourself a little about the inconvenient realities of wind energy, (to borrow that excellent phrase). Try my circuit breaker experiment to find out how you like the irregularity of wind energy. If you won't try it for a week, try it for ten seconds... at least.
BTW: The goofy picture for this article appeared in DN on Nov 06, 2004.
I have educated myself on this issue, thank you very much.
Maybe YOU should educate yourself a bit so that you can rebut the points of my earlier comment instead of ignoring them and hoping that your condescending tone will make it seem like you addressed them.
We will have storage capabilities for wind and solar within a few years, and in the mean time every minute they're feeding energy into the system is that much less coal and smog. And if we'd get on the ball in the manufacturing sector we could make it even more cost effective; but as it is, most technology and parts are imported from Denmark; in the near future China, India, and Germany will have competitors in the marketplace. But because we listened for too long to technological pessimists like Dick Cheney, we never got in the game.
It's not too late.
I just can't make any sense of your effort to paint wind energy as a bad thing.
Our electric power utilities do a great balancing act of providing stable power over the grid. The part-time lazy and part-time he-man output of windmills plays hob with that balancing act. It will always need a lot costly help to make it useful.
The $torage capabilities you mention...will cost a lot more money to install. The $torage ideas involve vast amount$ of expen$ive and huge machinery or very $pecial sets of circumstances to make them practical.
Energy $torage = Money $pent!
Nuclear has super-powers. By that I mean that it not only provides baseload, but it provides essentially no-cost power, as far as fuel consumption is concerned, in off-peak times.
Environmentalists need to get their heads out of the sand and remove their aging battlements/roadblocks against nuclear power so it can surge forward. It will take a team of technologies--(including conservation)-, especially including nuclear to keep America a first world economic power.
Nuclear has the track record of preventing GHG's = 16 billion tons. That is four times the mass of the Kennecott waste pile along the west side of the valley.
Take another look at the picture for this DN article. The blades are stopped, or nearly so. and there is no power output when it is cold and beclouded.
Learn the basic lesson from the picture.
Oh, and at least try the super-short lesson on turning your power off: turn just your kitchen light off, pretending you were on wind power and the wind stopped...lights OUT!

(They're also an enormous waste of taxpayer dollars, decimate raptor populations, and destroy property values. But never mind that, in the eyes of the Deseret News' editorial writers, they are "symbols" of all we should strive for.)
Give me a break.
