A bad rep for solar tax credit and LEED

Some news and rumors still seem to spread more by word of mouth than online. One of them for me is the issue of potential misuse of solar tax credits in the US, as opposed to feed-in tariffs done elsewhere. Solar tax credits are transferable and cost-based - the higher the cost of the system, then the greater the tax credit that can be sold to other businesses. That's an obvious disincentive to lowering solar costs, but less obviously it incentivizes leasing companies to inflate their cost estimates. When the IRS starts getting involved, that can really damage the political momentum we want to keep in place just as solar becomes increasingly competitive.

The solution is to play clean, folks, and maybe tighter IRS supervision. And maybe a feed-in tariff instead. Same word of mouth tells me the feed-in that's been tried at local levels in California is too small to get business support - we need a state or federal solution.

Similar issue for LEED, an environmental rating system for building design. Word of mouth that I hear is that it's way too easy to game the point system, especially because it's based on design standards instead of actual performance. Additional complication in California is that our state-mandated building design standards do a lot that LEED does, raising the question of what value LEED adds.

I've heard less about the Green Building Council standards, other than that they're supposed to be somewhat more lenient.

Yglesias discusses the issue here. As for his "price carbon" solution, good luck with that, at least on a national level (we're getting somewhere with California's cap-and-trade). Short of that solution, we need to have some performance standards incorporated into the rating system.

Crowded crowd-funding for solar projects

On Monday, Mosaic announced it would do the first-ever crowd-funding of solar projects, with a $25 minimum investment.  Yesterday I tried to buy in myself but their four new projects are fully funded.  They look like they might be having the same problem that Kiva used to have - more money than projects (it also seems like a different model than Kiva, the money goes directly to the projects rather than paying for a general fund).

Crowd-funding seems like a good way to get micro-investors involved in startups that would otherwise be impossible, to open up a new source of money for investment, to fund smaller projects that are too small for traditional investors, and to fund entirely new and different ventures that venture capital funders find uninteresting.  My impression is that Mosaic serves all but that last interest.  Obviously no one knows if it's going to succeed but it's just as obviously worth a try.  Maybe eco-grandparents will start buying Junior shares in solar projects instead of a stock as a college investment.

The other advantage is for people who want to do something renewable but can't do it on their own property.  Our townhouse has a small roof facing east/west with shading on the east - not an ideal place for solar.  Mosaic might be a better use of money to offset our emissions, and as an offset that others can use.

The bridge we need? Fracking depends on context.

Whether fracking for gas really is a bridge to reduced greenhouse emissions depends on context - does gas replace coal, or not?

That may seem too obvious to be worth discussing, but it's helpful to me as a matter of geography and chronology, especially chronology.  The reason for time being important depends on whether you accept that the long-term trend of significant decline in solar power costs, faster than efficiency for coal, will continue in the future and reach grid parity.  Similar evidence for wind, if not quite as dramatic.  I'm mostly buying these arguments.

On the geographic scale of the middle and eastern US, fracking has clearly replaced coal, and seems beneficial from a climate perspective (ignoring the other environmental issues).  In the western half of the US and much of western Europe, coal is much less important a power source, and gas from fracking seems more competitive with low emission energy.  When you add the chronological aspect that fracking will take 5-15 years to really develop, the same time period when renewables are approaching grid parity, then the argument for its development seems a lot shakier.

Exporting gas from the US will also take a decade or more, so again from a climate perspective, that only makes sense if the exports replace reliance on coal.  Maybe in China, India, and other developing markets, the climate would be better off if they had more gas.  Exports to Europe would be bad, I think. Not sure where the gas is really anticipated to go.

Fracking is an emerging issue here in California, where we have very little coal use to displace.  And even more locally in Santa Clara County, we've got lots of shale, where we've stored in underground aquifers a year's worth of drinking water for 1.8 million people.

Climate related comments elsewhere

At Same Facts, James Wimberley continues to do a good job IMHO of defending the "solar on track to be cheaper than coal" idea. I wrote:

What I’d be most interested in knowing is the rate of starts for new coal power plants, especially in countries with no local coal supplies (therefore no coal lobby). A new plant takes a couple years to build and 30-50 years to pay off, so [Efficient Market Hypothesis] (if accurate) would expect to see a significant dropoff for these.

At Nature, on a post about whether mastodons got stuck in post-earthquake mud and starved over a period of months, I skepticized:

I follow climate change denialism closely, so I'm very suspicious when non-experts proclaim themselves to be personally incredulous regarding a conclusion by experts. 

That said, as a non-expert, I am personally incredulous that partially submerged mammoths couldn't pull themselves out of the soil when liquefaction had ended. 

Tar pits I can believe. Full submersion and immediate suffocation I can believe. But being stuck in one spot and slowly starving to death without being able to pull their legs out of the soil, is something that needs to be a little more convincing. Maybe they need to a mechanical analysis of soil strength and compare it to an elephant's strength.

Sure felt like an article I would read on April Fool's Day, but what do I know. (UPDATE:  the teeming hordes of pro-stuck-mammoth factionalists attack in the comments, all two of them, and I guess they have a point.)

Finally, not a comment but a link to an interesting NY Times article on growing crops underneath trees.  No mention of albedo issues from trees being darker than typical ag, though.
