This is amazing computer animation . . .

I deleted #7640. Something about it was evidently keeping subsequent ones from showing up.

Did you even notice, Jex? What kinda autopilot you got there?

Windpower - Environmental Eyesore?

Worse than oil rigs off Santa Barbara

7648. jexster - 8/17/2008 1:47:45 AM

Yea I noticed that. Nothing I could do about Wizzers viral bomb.

7649. jexster - 8/17/2008 1:48:48 AM

What do you suggest Arky. Maybe I could post a few hidden requests that someone clean it up!

Jex - that windpower article is a scream.

My favourite bit :

(The companies have changed names and ownership several times and the Maple Ridge Wind project is now jointly owned by PPM Energy of Portland, Ore., which is part of the Spanish company Iberdrola SA, and Houston-based Horizon Wind Energy LLC, which is owned by the Portuguese conglomerate Energias de Portugal.)

Once i mention to people about our green house, I find i learn all kinds of things. Yesterday a guy started talking to me about cogeneration for residential use...apparently it's big in Europe...no surprise with their high energy costs...but it's not common here. Might be a good solution for those who can't retrofit to geothermal.

See here or here

I also learned that there is a more efficient geothermal system available where, instead of circulating fluid, they use gas so pumps to move the fluid are not required. Apparently it's a newer technology and good for smaller applications, but not larger ones.

hum yes, but they burn gas.

I finally billed the electricity company the other day for the first time, for my PV generation!

The system has actually been generating for nearly 6 years now, but I didn't like the look of the contract they were proposing in those days : they only offered to buy surplus production (i.e. net metering) not total production, and the kwh price was pretty mediocre, about 15 cents. So for five years, I was giving it away.

But about a year and a half ago, they re-jigged the contracts : this was actually a consequence of EU integration and the end of the national electricity monopolies. I could have sold my green electricity to a German company for a much better price; so of course, EDF upped their offer. I signed on for 20 years at 55 cents a kwh, selling all my production. So giving it away was actually a smart move, because now I can pay back the investment in 4 or 5 years, instead of 12 or 15 if I had signed up for 20 years at the old rate.

When I looked at the meter last week to bill them, I was bitterly disappointed : it only showed 1700 kwh generated since last August, I was expecting nearly double that. It's taken me a week to work out what the problem is... (I feared for a while that the panels were prematurely ageing. They're alleged to lose about 1% a year.)

... in fact, when EDF installed their meter to buy my power, they didn't cut the link that feeds directly from my inverter to my switchboard. i.e. I'm consuming some of my solar electricity directly, instead of sending it into the grid (then buying it back once I've sold it...)

So this weekend I will fix that... and next year's bill should be a much fatter affair.

For the co-generation thing, I'll wait for these revolutionary fuel cells mentioned up thread a bit.

7655. thoughtful - 8/20/2008 9:59:13 PM

AC, call me dense but I don't understand how you're better off selling it all to them rather than using some yourself...do they charge you less to use it than you receive when you generate it?

In our area, net metering is the only way to go as if you overproduce, the utility will only pay you wholesale prices for the amount you give them while charging higher retail prices for the amount you use. Therefore it makes sense to undersize rather than become a net power generator.

I was using Google maps today and noticed they expanded their "street views". My house is clearly photographed from several angles. I looked up some known addresses and found clear photos of those houses. It's all very strange, and I don't really see the point of photographing noncommercial areas.

7657. alistairConnor - 8/21/2008 8:19:04 AM

In Yurrup, my dear, they pay above-market rates for solar, to encourage generation. (The Germans did it first, obliging the others to follow suit.) So, yeah, when I consume during the daytime, I am actually buying back my own power at a cheaper rate. ("Will be"! I have to modify the wiring first!!)

The French method of encouraging solar was, typically, bureaucratic : I actually got more than half my investment back through subsidies. Now I get the German price too. So I'm double dipping. Not bad for what was originally a quixotic gesture.

Ahh so. You crazy Europeans!

I just saw what looks like a sensibly green car for the City...parked just around the corner...great for parking space war
