If Western Europe can do solar so can we.

Discuss.

1. Nothing to discuss. I agree. I live in Seattle and I've heard it's even doable here --
on a limited basis, but we're workin' on it!

5. Actually Seattle is a great solar area - surprisingly
If panels get too hot they lose efficiency. I guess that makes E. WA especially great! But methane is dispatchable - can be used to generate when it's dark and not windy. Also geo thermal and tidal. SnoPUD north of Seattle is dveloping that with help from FERC IIRC.

Also, correcting for power factor, stopping air leaks etc etc etc - will drop demand 35-45%.

6. Larry Hagman claims he reduced his electric bill from $37,000/yr (sic) to $13 dollars! on his ranch
thirteen dollars.

That's what he claims. I've not seen his bills!

Larry Hagman, who played Texas oil tycoon J.R. Ewing in the hit 1970s shows Dallas and also starred in I Dream of Jeannie, is calling for people to embrace solar technology as part of a new "Shine, Baby, Shine" ad campaign for solar panel manufacturer SolarWorld.

"In the past, it was always about the oil. The oil was flowing and so was money. I quit years ago but I'm still in the energy business. There's always a better alternative. Shine, baby, shine!" Hagman, 78, says in a commercial posted on the SolarWorld website, before cackling happily.


The ad shows him looking at a portrait of himself as Ewing, exiting his hillside estate in Ojai, California, where he lives with wife Maj, and looking up at a red roof containing a solar panel.

Hagman is a longtime advocate of renewable energy and owns one of the largest U.S. residential solar panel systems, which cost him $750,000 when he bought it in 2003. He says they reduced his annual power bill from $37,000 to $13.

12. Solar Electric Costs
Edited on Sat Mar-12-11 03:32 AM by jasperfondoon
If Larry Hagman paid $750,000 for his PV system and is saving $37,000 a year, it will take just over 20 years before the system starts paying for itself. That's quite a long time to recoup your initial investment. Come up with a much cheaper PV system and you'll be a winner. But, not like Charlie Sheen.

Put solar panels on every building in LA, and Southern California will have energy to spare.

As usual, today was warm and sunny. (We do have some cold days and a few, very few, rainy days.

I transplanted lettuce (and a few other plants I grew from seed) most of the afternoon.

My California poppies, roses, lavender, geraniums, begonias cosmos, nasturtiums. . . . . . . are in bloom.

I have a bunch of tomato plants growing. Tomatoes have already set on for a couple of them. In some of my neighbors' yards, the tomato plants that they planted last year are still growing and have tiny tomatoes on them. My baby figs are just starting to appear. (Cute little fellows.) The sun never stops shining for long in Southern California.

It is a waste to have so little solar in LA.

23. Think about it
Edited on Sat Mar-12-11 10:34 AM by CommonSensePLZ
A couple of candles, a really good flashlight or lantern can't light very well, even the full Moon can't. The Sun is 398,359 times brighter than the full moon. Use an oven or radiator to heat a room, maybe somewhat efficient. Use the Sun and you can heat a whole half the world, but this is what Wikipedia has to say:

In 2008, total worldwide energy consumption was 474 exajoules (474×10^18 J) with 80 to 90 percent derived from the combustion of fossil fuels. This is equivalent to an average annual power consumption rate of 15 terawatts (1.504×10^13 W).


Most of the world's energy resources are from the sun's rays hitting earth. Some of that energy has been preserved as fossil energy, some is directly or indirectly usable; for example, via wind, hydro- or wave power. The term solar constant is the amount of incoming solar electromagnetic radiation per unit area, measured on the outer surface of Earth's atmosphere, in a plane perpendicular to the rays. The solar constant includes all types of solar radiation, not just visible light. It is measured by satellite to be roughly 1366 watts per square meter, though it fluctuates by about 6.9% during a year—from 1412 W m^−2 in early January to 1321 W m^−2 in early July, due to the Earth's varying distance from the sun, and by a few parts per thousand from day to day. For the whole Earth, with a cross section of 127,400,000 km2, the total energy rate is 174 petawatts (1.740×10^17 W), plus or minus 3.5%. This value is the total rate of solar energy received by the planet; about half, 89 PW, reaches the Earth's surface.


New York city uses about 27 gigawatts (27 million kilowatts 27×10^9)
(http://en.wikipedia.org/wiki/Environmental_issues_in_New_York_City#Energy_efficiency)

Therefore if I've done my maths correctly the world receives perhaps around 100 thousand times the energy New York city uses in a year from the Sun in one day. :o

That's free fucking heat and light everyday for billions of years. But we're starting to get desperate for gas.. I'm only going purely by the numbers and the sheer magnitude of the energy we get from the sun when I agree that solar power might be a good idea, I'm no expert.

The vast majority of their electricity production is from nuclear power.

Which doesn't even count the fact that they export large amounts of the stuff too.

If you compare what they generate with nuclear to what they consumer in electricity (netting out the exports), they're pretty close to 100% nuclear.

84. You said most of their POWER not most of the ELECTRICAL power.
France's energy usage break down to 38% nuclear to generate electricity, 34% oil, 16% gas, and the rest hydro, coal, renewables, etc. (FYI, in my original response, I meant to say gas or oil - not coal.)

So yes, gas and oil combined supply 50% of France's energy needs.

21. Of course, you are right, but we have been stalling on every possible method
of using alternative energy sources here for several decades...whenever oil gets cheap, we all go back to sleep and forget to promote solar, wind, bio, etc...The same with the "crisis" in Social Security-didn't the politicians think the boomers would ever get older and retire?
They act like it is all a big surprize to them.
We should demand a refund of all the pay and benefits of all our elected officials over the last 40 years because they obviously did very little of any value while having a great time at our expense.

So is hooking a generator up to your exercise bicycle so you can watch TV.

The problem with both is that you don't get enough power to actually drive a modern civilization. (and, of course, you sometimes need power at night).

If Western Europe can do solar so can we.

Western Europe is "doing" solar?

What percentage of their total electricity generation would you guess is currently supplied by solar (direct solar of course)?

I would like to see both.

My town has been trying for quite a while to find some suitable spot to erect a wind tower but no luck so far. There are plenty of windy spots, but the locations themselves are probably not entirely suitable.

Like my driveway, for instance.

*And was able to, anyway

30. i looked into solar electric once
a couple years ago when I was living in madison. I went so far as to have a solr assesment done to see if it was feasible. I would have had to cut a tree down to make it work which I wasnt wiling to do anyway but what I found was the cost was prohibitive.
To supply all the electric my hous eused the system would have cpst 50-75k. even with the rebate the by power company offered it made no economic sense to do it.

solar hot water on the other hand would have made sense (if i removed the tree)

Im sorry bu solar electric just doesnt make economic sense yet..

33. I've used solar for most of my life. It is awesome.
My system paid for itself many years ago. My solar panels just sit there and provide me with basically free electricity, except that about once every 7-10 years I have to replace batteries so that costs me about $500. But I figure I'd easily spend that in a year buying electricity from a corporation.

Giant energy producing companies generate more than electricity. They generate huge masses of bullshit too. The last thing they want to see are widespread alternative energy systems that are not a constant source of profit for them. So they spread their talking points and the sheep bleat them over and over - like this - "solar energy is baaaaaad baaaaaad baaaaad".

It is so annoying.

34. Solar energy is not bad ...
.... but, there does need to be a discussion of the wastes related to the production of the photo-voltaic cells (specifically mercury and chromium) and the disposal of retired cells.

Its a smallish issue at this point in time due to the very limited use .... however, massive production and use does raise some issues.

All methods of mass production of power has significant environmental consequences. No discussion is complete without discussing reducing our use of power (generated by any source) ... SIGNIFICANTLY.

35. Of course there are problems regarding waste...but -
Solar cells last 20 years or more. My current panels are 11 years old.

Relatively speaking, the amount of waste generated by using solar systems on a mass scale would be insignificant in environmental impact and toxicity compared to the waste generated by fossil fuels and nuclear power production/use/storage/transportation. I suspect recycling of materials is already possible to an extent and/or would be possible if serious research was done.

But I do agree with you that producing probably anything on a mass industrial scale presents a waste problem.

37. Yeah, well, it works great for me, and I have generated miniscule environmental pollution
from the use of solar power in my life. Maybe some escaped gas from batteries.

But, then again, you apparently are an expert on solar; and I, alas, am just a lowly armchair proponent.

But hey! Limiting energy usage is a fantastic idea! In fact, I have probably used 1/100th, maybe even way less, of the amount of energy used by the average person my age in the US over my lifetime.

So, what kind of power do you use in your home?

Nuclear, or fossil fuel?

Your responses to posts that state that solar is a good alternative ....but not perfect appears to really rankle you ...?

Is it my assertion that a more important discussion is that of cutting our consumption of power is the most important facet ... ? I stand by that. As a whole, the best alternative is to drastically cut our consumption as a society ... this will have the largest impact.


Odd

edit to add: I don't claim any expertise related to the production of photo-voltaic cells. I do claim some knowledge related to the handling and disposal of hazardous waste and I claim some knowledge of site remediation associated with contamination with these materials.

45. You go first.
Try living without your computers or heat/air-conditioning, hot showers, etc. before you lecture the rest of us to reduce our energy consumption.

The more technologically advanced a society becomes, the more power its industries needs to thrive.

We aren't going to be reducing our energy foot-print any time soon. We need power, the only question is what is the most cost-effective way of getting it while minimizing potential harm to the environment?

47. I have
Not nearly enough .... but I have.

I drive a small fuel efficient vehicle, my family and I live in a very small energy efficient home. I have traded "size" for efficiency (which oddly, is frequently more $$$) in most aspects of my life. i am so far from perfect .... but I keep working toward being better. I don't mind being the first (i'm not ... but in response to your post)to make sacrifices.

My point is this: if we switched our (a collective societal "our")reliance to solar power for all of our needs (for home, industry ...) we are simply trading problems if we don't drastically reduce our consumption .... Japan is an excellent (my heart breaks for them right now) example of cutting consumption (living spaces are small, transportation is comparatively efficient).

If you read my posts at no point do I criticize the use of solar (aside from pointing out that its not perfect ... its not) .... I simply state that its use on a societal level will bring its own problems with out tremendous reductions in our consumption.

Get real dude. Of course it isn't, and you damn well know it. I specifically wrote that I think cutting consumption of power is a great idea.

69. You made your own photovoltaic cells and panels?

So, did you use mono or polycrystalline material to start, or did you make your own silicon from scratch? What chemicals did you use for doping and what was your metallization process?

Or did you make amorphous panels from organosilicate gases? And did you make them from scratch?

Seriously, I want to hear about this "no waste" solar panel production method, because when I was in the industry, the handling of a lot of organic solvents and other chemical waste was atrocious across the board.

Edited on Sat Mar-12-11 01:12 PM by fascisthunter
because I don't see people here romanticizing anything, and I would think that anyone who understood the ramifications of nuclear fallout would be a proponent of an alternative rather than dissuader.

56. At what point do you think I favor nuclear?
I favor small efficient homes and vehicles. I favor mass transit. I favor efficient industry that is encouraged (actually mandated) to make initial (costly) investments in efficient processes.

I believe in utilizing energy from a multitude of sources, but using it sparingly. We have a culture that squanders our resources. You can be offended by that statement ... but it is my fervent belief (right or wrong it is what I believe)

I have no problem with "solar" ... and actually am in favor of it in many many settings .... I don't feel that the "public" at large has any idea of what goes into the production of photo-voltaic cells .... or what goes into the generation of power.

43. I'm going solar at home. My rooftop grid-tied PV system should be installed some time in April.
Edited on Sat Mar-12-11 12:39 PM by slackmaster
I expect to reach the break-even point in about seven years, coinciding with the payoff of my mortgage.

The only thing that could foil my plan would be San Diego Gas & Electric discovering a previously unknown, limitless source of cheap electric power and cutting everyone's rates.

55. You are 100% right. Utility companies will go for it
...until we go off-grid too much with community energy generation. But by then it will be a done deal.

Communities are starting... rural communities seem to have that 'farmers' co-op' ability that cities don't. They have methane sources too, which generates energy when the sun goes down and the wind stops blowing.

DER (Distributed Energy Resources = various types of alternative nergy) will be needed to make it work. Solar's good for commercial loads which happen during the day, but residential is generally a night time load.

64. Solar panels put out DC voltage, Computers use DC voltage
Edited on Sat Mar-12-11 02:12 PM by upi402
We convert DC to AC and then the computer converts AC back to DC. Each conversion wastes energy, causes heat which electronics hate.

Seems smart to avoid the cost of equipment and waste of solar energy. I found a manual for a junk puter online and was able to label voltage needed by each of the groups of wires coming off the power supply in the puter.

Next I'm looking at using resistors as a voltage divider???? Just chewing on an idea...

60. I have thought about that...
It is time to de-centralize power production and put it in local hands. Keep the money where it is produced and used. Less need for wars and more resistant to price swings.

82. Germany's energy policy is nothing to emulate.
Edited on Sat Mar-12-11 05:09 PM by JVS
They actually stopped making Western reactors and ended up importing energy from old Soviet reactors in the Czech republic. Even their green party is permitting the construction of new coal plant. Also, they have hampered themselves with an energy policy that avoids nuclear because the issue of nuclear weapons and nuclear power became conflated in the public mind during the cold war.

65. Our national grid isn't built for utility-scale solar.
It makes the most economic sense to have utility-scale solar power plants. Unfortunately the places you would most likely put it are far from the coast, which is where most people live. The grid can't handle massive output from, say, Nevada to the Western coast. We also need better storage. We currently just consume what we're producing as we produce it. Can't always do that with solar. Similar arguments can be made about wind.

Don't get me wrong, I love solar and wind. Heck, I was one of the founding members of Ohio State's 2009 Solar Decathlon team. If you aren't familiar with it, I recommend checking it out.

Use the solar to produce hydrogen. Ofcourse that would also require transportation, but we already have some sort of distribution for petroleum.

79. Where are you getting that baloney?
California was swindled out of billions of dollars and made into black-out crisis by Enron and other traders fraudulently manipulating the grid. Californians responded by conserving up to 40% of power and scared the crap out of the industry. Gray Davis was taken out as governor so that California would not sue the cheats to get the money back and throw them in jail. Junior and Arnold were their guys.

A solar system on each home and business with battery storage power tied into a grid is the ticket. Try 20 million cars here in California each with a 20KWh battery tied to a smart grid with 10 million 8KW residential and 100 thousand 100KW business solar systems for sustainability. We can do it in 5-10 years if there is the will.

93. You haven't actually disputed anything I said.
Putting that part aside, you're right. If each residence has its own production and storage then that could work. But now you're requiring everybody to purchase and install a PV system and EVs. That's incredibly expensive and not always practical. In addition to all that, it makes little sense to go through all that trouble to power an inefficient house - a ton of what you produce will just be wasted. It makes more sense for people with limited resources to spend the money on updating old appliances, replacing old windows, and insulating their houses. After that, I'd rather have people install solar thermal first, preferably in conjunction with a radiant floor system for heating. Solar thermal has a faster ROI than PVs.

I'll admit I don't have enough knowledge on the commercial implementation you suggested. As I said, my experience was with residential. But the one problem I foresee is maintenance. We need better batteries for that.

Sorry, but the only way you're realistically going to get solar up any time soon is if you do utility-scale, concentrated solar. Even that's being held up by environmentalists worried about potential impacts on reptiles and such.

67. Because you are ignorant of the toxic chemical mess of solar production

But, hey, the Chinese will poison themselves for your "clean" power, so, cool.

Photovoltaic panels just come shooting out of the assholes of grass fed free range unicorns in your world, I suppose.

The SVTC warns that solar panel production creates many of the same toxic byproducts as those found in semiconductor production, ...

http://cleantechnica.com/2009/01/14/danger-solar-panels-can-be-hazardous-to-your-health/


And how does this pollution compare to nuclear or oil pollution? Does it contribute to global warming or wars? Can it be lessened or changed to minimize it?

Look at the list of chemicals that are in our food and water and air that could be hazardous to our health that we really don't know the toxicity. Thousands and thousands that are untested.

70. Europe is trying to get out of the vise-grip.
We should be too. Safety or economics or both will determine where we invest.

Probably the most important but least immediate safety issues of fossil carbon burning is global climate warming, and that overhangs us all. The other dangers of burning oils are wars to secure future sources, and becoming stupid from terrific propaganda to support these wars and to deny the dangers of this pollution. Then there is the dangerous costs to freedom and the pocketbook to protect against these infuriated and desperate people that these invasions and occupations create.

Which ties in with the other topic of nuclear safety. Nuclear power plants and materials have to be protected from these desperate and radicalized people that would use it as a weapon, practically for ever. And as Mother Nature has just shown, the materials are inherently dangerous and risky.

While solar, and wind power for that matter, are produced locally and variously and so are not as vulnerable to disruptions and accidents. Also, the electric power generated can be stored in batteries and as hydrogen for off-production time use, and shared into a grid.

Plus Solar is going to make us employed and free from debts and wars and restore our personal freedoms. And make us romantic as hell and in touch with nature at the same time.

I think it will be a combination of things. Wind, solar, and fossil fuels during peak loads, and when mother nature doesn't cooperate. In the worse case it would be night with no wind blowing.

92. What's to discuss? It's obvious.
Solar, wind, wave...those are resources that aren't going anywhere as long as the planet sustains life.

They don't have toxic waste products; they don't come with health risks.

They simply require research and infrastructure that diverts resources from those with an interest in keeping riskier sources on top.
