Wind farms could supply planet's power

Recommended Posts

sounds good...

Even operating at just a fifth of their full capacity, a global network of 2.5 megawatt wind turbines sited away from urban centres would easily meet global electricity demands, a study suggests.

The Government has set a target of meeting 15 per cent of all the UK's energy demands from renewables by 2020, which means between 35 per cent to 45 per cent of electricity will have to come from green sources. Most of this is expected to be generated by wind farms.

For the new study, a team of international scientists led by Professor Michael McElroy at Harvard University in the US, divided the world into areas of around 3,300 square kilometres.

They then identified regions that would be suitable for wind farms.

The scientists worked out the potential for wind power electricity generation based on wind speed, air density, the spacing of turbines, and the size of turbine blades.

The findings are published in the journal Proceedings of the National Academy of Sciences.

The researchers concluded: "The analysis suggests that a network of land-based 2.5 megawatt turbines operating at as little as 20 per cent of rated capacity, confined to non-forested, ice-free regions would be more than sufficient to account for total current and anticipated future global demand for electricity.

"The potential for the contiguous US could amount to more than 16 times current consumption. Important additional sources of electricity could be obtained by deploying wind farms in near-shore shallow water environments."

As much "fun" as wind farms are, they aren't a perfect solution by any means. While they look "cool" is sci-fi movies, the reality is they're not really all that attractive. While the cost of operating them could potentially get quite low, the real estate costs could be quite high.

Take the coast of California for example. I can't in my wildest imagination believe that even California would put up with having the view of the coast screwed up with wind towers. We have a great wind farm on the road that leads from Palm Springs to Los Angeles and it's in a consistently windy area as well. Great location. But the article's idea that we'd somehow give up the coast line? Preposterous.

They're built about 20 miles off shore, so the change to the view from the California coast would be negligible.

We have county suporvisers here, already banning them in some counties. And we are talking on farm land here.

Also, new sites are getting harder to set because the potenial site land owners are talking to those who already have them. And when the current site owners are saying in hind site I would have never let them on my land, new sites are hard to come by.

But, like billvon, government can force landowners to allow the things on their land, much like billvon gets free use of the utitity company's poles and wires.

Some folks pay good monet for that .... Ask Bana..... But I digress.

That's true but our little island is being blighted by these damned things - you may have loads of empty spaces so that peoples lives aren't messed up by some corporations idea of that is good for us (whilst they live well outside of earshot of them) but we don't.

Also, how efficient are they (really)?

How much do they REALLY cost (materials, shipping, energy etc.... etc...)

What is the TOTAL Cost of Ownership of these damned monsters?

How long does it honestly take for them to pay back this TCO?

-kill birds...

Not as many as the envirowackos would like you to believe. According to the study below, the average bird kill is two per turbine per year. Sounds like a fair trade for oil independence and reduced air pollutants!

as far as being noisy and ugly, have you ever seen a coal fired power plant?;)?

I believe that they are having that debate... It's profile changes from time to time but energy in general is pretty high on the agenda. ...... of course 'they' seldom ask for 'our' input:(

Lot's of people try to resist Wind Farms being built in their neigbourhood ... mostly with no sucess at all.

Big money corporations 'tend' to drive policy.

It seems to me this is a perfect case of "one size does not fit all."

Wind farms are great, in some places. Southern Idaho and Northern Nevada, for example, have huge chunks of desert, with high winds. No one lives there, and they are great places for wind farms.

Sticking them in the middle of populated land really doesn't make sense in very many places.

When the government intervenes to try to "build wind power" we end up with wind farms where people don't want them, rather than where they make sense.

As a side note, did anyone else read the article about building wind farms on tethered balloons in the jet stream? Interesting stuff.

I would wager that most people resist coal plants and nuclear plants being built in their neighborhood as well. I'd be curious to see a poll on which of the three people would be the least happy to see in their neighborhood.

Where they make sense is up for argument. Sure, building them in the middle of nowhere makes sense aesthetically. But then you have to consider that you're going to have to build transmission lines to get the power from the isolated wind farm to the end users. You're also going to have to build more turbines, because more the electricity will be lost covering the distance between the turbines and the end user. What makes sense really all depends on what's important to you.

Absolutely.

That debate ought to be had amongst the people living there, though. Not amongst a bunch of people thousands of miles away who decide for them.

i'd read about high altitude kites that continuously looped and generated electricity.

I would also add that wind is not the solution for every place, as others have said. Those who plan renewable energy projects have long recognized this, but those who oppose renewable energy (usually the NIMBY crowd) like to quote it out of context and claim that the projects are not viable.

OK, maybe wind is not the best plan in the UK. Is there Anything going on over there regarding tidal energy? Spain recently had some success with this technology.

it looks like a continental/global dc transmission network will be able to connect up the remote renewable sources.

there's a plan to build a tidal barrage across the bristol channel (i think the second biggest in the world) that will possibly generate about 5% of the uk's energy.

For FUCKS sake! You can't win with the enviro's! No coal! Dirty. Wind Farm, noisy and kills birds. Solar field! NIMBY! Nuke? To risky. Dam? Harms the waterlife. OK so how do you want us to generate power?
If you find yourself in a fair fight, your tactics suck!

How do you figure?



I thought you told me that you get to sell your exess juice at retail to the power comany. Did I misunderstand you?

If I have it right then the power company sells the juice you sold them at the same price. So, they get nothing for the electricity and you get to put it out on their grid for free.

Saying it another way, You are selling at retail (and retail prices, which contain the mark ups, generate the margin needed to build and maintain the grid) and they get nothing for it and you use it for free.
