No, not really. I personally believe that there is no compelling evidence that AGW exists, or that CO2 is in any way a pollutant - but that has absolutely *nothing* to do with why I'm against solar subsidies, whether backed by the GOP, the Democrat party, or anyone else. (Not solar itself, note the difference...)
(Disclosure - I've spent the last five years in the solar industry, dragging it kicking and screaming into the modern world...)
Solar still has a great many problems, and is very, very far from the panacea that most people in the industry (and green fanboys) delude themselves into believing.
First, solar is not economically feasible without huge government subsidies unless you live on an island or similarly remote area and have to ship in your fuel. This is not easy to change - panels are cheap (and getting a little cheaper), but most of the money in a solar install is not the panels, but rather the BOS (balance of system) cost. BOS costs are NOT falling, and may be going up with increased regulation. Let solar grow into the places where it makes sense - subsidies only distort the market and create huge incentive for graft, corruption, and cronyism. (Solyndra really is a great example here - it was clear from the very beginning that there was no way a company could spend $7/Watt to build goofy tubular PV and sell into a market where top-grade German panels could be had for $4/W. This was just the worst sort of corrupt cronyism on an unprecedented scale.) Recent studies in Spain have shown that any ground-mount array not only produces marked ecological damage, but that you will *never* recover the site prep energy required by a large-scale ground-mount array. And we're just starting to wake up to the risk that rooftop solar arrays present in a fire - there are downsides to materials that MUST (according to quantum physics) produce voltage when exposed to sunlight - many fire departments are instituting "watch it burn" policies for building with rooftop solar arrays, since there is no other reasonable way to protect firefighters on a solar roof. Bottom line, Solar is still *really* expensive, and not reliable enough to benefit the grid on a large scale. (Germany's grid is facing instability issues related to their relatively high usage of solar.) The US EIA reports that the LCOE (levelized cost of energy, taking into account lifecycle costs) of solar PV is at best about 3X that of combined cycle natural gas, with a capacity factor (availability) of only around 25%, compared to 85-90% for coal, gas, or nuclear. "Grid parity" is still a pipe dream.)
Second, solar panels don't last *nearly* as long or work nearly as well as people (including the manufacturers) say. I know - my team built and collected the largest database of per-panel performance data the world has ever seen. Very minor soiling (say, a business-card-sized drop of bird crap) eliminates 1/3 of the power output of most panels. Add another one or two in that string, and you've now removed that entire string's power production from your array. Even a little shade, as you might expect, can cripple the performance of entire arrays. The harsh economic reality is that you need at least 20-25 years of production to breakeven - even *with* most subsidies. (With current technology, the power output of even quality panels degrades very rapidly after about 20 years. Yes, that's right, you get to re-buy your solar power generation every couple of decades, and deal with difficult-to-get-to toxic heavy metal waste in the old ones...) There are good quality panels out there that last, but we're starting to see way too many arrays with third-tier Chinese panels beginning to fail in the field after only 5-8 years (delamination and backing failures being the most common). Arrays being built with most of the crap that's on the market now will *never* breakeven. (And even the Chinese cannot afford to continue selling panels at current prices - a shakeout is virtually inevitable, and will traumatize the industry even further.)
Third, this is without question the sleaziest industry I've ever seen, much less been involved in. The "true believers" are deniers of the worst sort, refusing to look objectively at anything that doesn't comply with their green-tinted preconceived views. I know lots of people here love to villify the oil industry, but I've worked there too, and I can *honestly* say that the oil industry not only operates in a vastly more ethical way than the solar industry, but having worked in building oilspill response networks for the largest oil company in the world, I think the oil industry actually has more real concern and stewardship for the environment. (The toxic heavy metals washing out of most Chinese solar panel plants is staggering - these things are NOT clean to make...) Now to be fair, most of the people flogging solar are well-intentioned, but they are way too quick to look the other way rather than face the sometimes-ugly reality of the industry.
That said, I actually want solar to continue to develop and become an important (if always unreliable) power source. Solar PV (along with other forms of distributed generation - perhaps natural gas microturbines and fuel cells) *will* eventually make sense, but we're probably some years away from that point. I've even looked at putting solar panels on my own house, but concluded that it still doesn't make economic sense even with the relatively high subsidies offered here in Austin. That may change one day, but barring huge improvements in technology, manufacturing, and policy, it's not going to be soon.
