The Solar Industry's New Dirty Secret

[div style="float: left; padding-right: 12px;"]"It's no secret that manufacturing solar panels often requires toxic heavy metals, explosive gases, and rare-earth elements that come from shoddy mines in war-torn republics. But here's a surprise: The solar industry is actually getting dirtier in some respects. The latest Solar Scorecard from the Silicon Valley Toxics Coalition (SVTC), released last week, reports that the industry has slipped on several key environmental metrics, with many solar-panel manufacturers now refusing to provide any information about their manufacturing practices at all.

In terms of market share, only 35 percent of the solar-panel industry responded to this year's SVTC survey, compared to 51 percent last year. According to SVTC, several major solar companies have provided almost no meaningful information about their environmental performance—stats such as the toxicity of their panels, the use of conflict minerals, or the sustainability of their supply chains—through reports to the group or on their websites.

"If they are not providing the information, we have to assume the worst," says SVTC executive director Sheila Davis."

solar cell technology has and is undergoing huge advancements and changes in materials and methods. Cells in the near future will not be anything like the old ones and are infinitely more environmentally safe from what I've read. There are many articles on the advancements in solar cell technology and you will find most of them posted on phys.org site if you care to browse.

I have no argument about the old cells having their problems with environmental safety let alone their poor performance.

Is it a surprise the nuclear fans would glom onto a report like this?

"If they are not providing the information, we have to assume the worst," says SVTC executive director Sheila Davis.


Actually Sheila Davis, no, you don't. You delegitimize yourself when you publish your assumptions as facts. If that is a window into the way you conduct business, perhaps it provides a better explanation for why the rate of cooperation is so low than anything related to the actual performance of the companies.

2. Then we pressure them to improve.

[font color="navy" face="Verdana"]No matter how you slice it, though, continued and increased use of solar energy is better than continued reliance on fossil fuels.

On edit, another thought: Since solar has become more popular, bigger companies like GE have invested more in developing it. Maybe the reason for the new secrecy in production is related to that fact? After all, the big corporations are not about doing the right thing, they're about profits, however they can get them. I'm betting that's exactly the case -- all the more reason to pressure for legislation forcing them to clean up their act.

I doubt we'll ever have 100% saturation on solar, but it's not far off the daily electric peak.

Schools, stores, and businesses should all have solar. There's usually a big area available for installation, and their peak use is during the day when solar is kicking out energy.

We had peaker plants before solar, and we're going to have them after solar too.

What if solar doesn't pan out and we instead rely on peaker plants for most of their "rated" power (actually, what's happening now)?

We need carbon-free energy.

It requires, at least at this point in time to utilize petroleum products to MAKE the stuff we need for solar arrays, hydroelectric dams, wind generators, wave generators and so on.

Solar is getting more efficient by the the year - and once it's up and running, it's pretty clean.

So is hydro-electricity - definitely NOT nuclear - too friggen dangerous, and the toxic continuous waste products are accumulating at an alarming rate.

There is no continuous toxic waste from solar, hydro and wind generators.

Given, they do have an effect on the environment, as does just the existence of 7 billion people on the planet.

If you have a totally clean solution for our energy needs,

I'd be very interested to hear it.

Nuclear energy is the safest form of dispatchable energy except for hydro.



The waste produced by an average coal plant is 400,000 tons/year of carcinogenic fly ash. The waste from a comparable nuclear plant is 27 tons/year.

and no link to boot!

However, when oil or coal fired systems have a problem, they do not pollute seawaters or land for decades afterwards.

Think Chernobyl and Japan's nuclear "accidents".

The devastating effects are still with us - AND - the USA is still fighting with states as to where to put their nuclear garbage.

USA did solve part of their problem by dumping tons of depleted uranium on Iraq in the form of bullets and missiles.

I suppose if the USA keeps its wars going, they can dump a whole lot of this toxic shit on the rest of the World.

Yes, oil and coal are dirty in the making,

but they do not have the centuries long devastation that nuclear is about to unleash on us -

maybe not right now,

but future generations are not going to remember the "nuclear generation" very fondly.

Count on it.

10. Nuclear is safer than both hydro and solar

The Banquiao Dam break in China in 1975 killed 171,000 people.

http://nextbigfuture.com/2008/03/deaths-per-twh-for-all-energy-sources.html

• Depleted uranium is not used in bullets and missiles to "dump" it - it's used because it's heavier than any other material.

• Coal and oil have caused far more pollution and millions more fatalities than nuclear, and will continue to do so

Annual deaths from coal pollution
Mercury contamination from coal

These are facts. If you want to contest them with better facts, I'm very open to continuing this discussion. However, I don't have a lot of patience for debunked Greenpeace hysteria.

the solution probably lies in better batteries and other storage, rather than better nucs. Imagine what several billion dollars in R&D could accomplish in this area, rather than supporting an industry that has been pampered with subsidies for sixty years and can not justify the fear it instills, to the general public.

Call it ignorance on one side, or instinct on the other, if you like; still, a publicly palatable solution has not been found in nuclear; it might be time to give the same monetary devotion to renewables and their supporting systems.

We've got backs to the wall and no time to mess around. Whether it's palatable or not, nuclear offers the possibility of salvaging some semblance of the world and the life in it that we're familiar with.

Renewables do not.

Renewables shut down fossil and nuclear. There is proof.

German energy giants pull plug on conventional power

German power company RWE is shutting six domestic plants and rival E.ON is threatening to relocate to Turkey as the sector tots up the cost of the government's energy policy turnaround.

...But the turnaround is depriving utilities, including market leaders RWE and E.ON, of massive profits from their atomic plants and turning their gas and coal-fired stations into loss-makers as they are sidelined by rival renewable sources of energy.

...Following the boom of solar power in recent years, nourished by generous subsidies, the capacity of renewable sources of energy is such that, if the wind is blowing and the sun is shining, Germany can actually do without its conventional power plants.

In the period from April to June, a number of RWE's plants were operating at less than 10 percent of capacity, said finance chief Guenther.

And with wholesale electricity prices at the current lows in Europe, that means substantial losses. That was the case with gas-fired plants until recently, but coal-fired generators are now barely profitable as well, he said....

It is in the process of happening here also and it is why the nuclear/coal utilities are so damned petrified of people putting a few solar panels on their roofs. In spite of the lies it is only going to get worse for them (you).

Cost of Solar Power to Drop 75% by 2020? US Military Embraces It
by Stuart Burns on AUGUST 20, 2013


Not one to shy away from overstatement, Ambrose Evans-Pritchard is not a writer we would normally quote extensively; well-renowned as the Telegraph newspaper is, for which he frequently writes in the Business section, but his article last week on solar power trumping shale gas even had us sitting up and taking notice.

True, many of the figures quoted in his article come from firms involved in the solar industry and as such we can expect them to put a positive gloss on the numbers, but we wouldn’t count the US Energy Department to be biased and they are quoted as saying they expect the cost of solar power to fall by 75% between 2010 and 2020.

By then, average costs will have dropped to $1 per watt for big solar farms, $1.25 for offices and $1.50 for homes, achieving what the Telegraph terms the Holy Grail of grid parity with new coal and gas plants without further need for subsidies. That’s the crunch, isn’t it – the subsidies. But if we think subsidies in the US or UK have been high, consider Germany, early starter in the solar power race.

Households have been bled dry to subsidize solar power – around €100 billion or more has been frittered away on costly feed-in tariffs. In addition, German investors have lost their shirts on a string of solar ventures that have gone bankrupt, only to see the gains leaked out to copycat companies in China which are able to undercut German rivals in their own market with cheap labor and giveaway credit.

Still, that artificially created market has spurred investment around the world; even the US defense establishment is heavily involved, with Evans-Pritchard quoting a string of projects, each of which will help bring down costs and improve efficiencies....

I think flywheels hold a lot of promise. For houses in suburbia, buried in the yard like septic tanks of old. The main thing is economy of scale. Start building them for industrial use, then downsize the technology for residential.

Here's an article that claims 80% efficiency.
