Dedicated production of biofuels has been a Holy Grail for the sector, but this study finds that this is unlikely.

How to misconstrue statistics in your favor: an example arguing against SB 32


statebystatechangeinco2emissionrateThis blog post on Fox & Hounds is an example of how to take statistics of one cause-and-effect relationship and misapply them to another situation. In this case, this graphic above shows how GHG emissions have dropped dramatically in states that used to burn coal to generate electricity, but now rely much more on natural gas. The decline in coal emissions has occurred over the last half-decade due to the fall in gas prices and the increased stringency in air quality regulations. But more importantly, those states had higher emissions that California to start with because they have been laggards in protecting their environments. The chart shows that these states are finally starting to catch up! If anything, this supports adopting SB 32 as a follow on to AB 32!

Yet the blog post misconstrues this situation to argue that it’s the “free market” that somehow is generating these greater reductions, implying that California and Mississippi had started from the same place–which of course if far from the truth. Yes, the market push from natural gas fracking explains some of this, but California was already so far ahead due to its own efforts that it has less room to improve.

Watch for these types of misrepresentations. Understand the initial premises by the authors. Ask hard questions before you accept their conclusions.

American Economics Association: Agricultural adaptation to climate change

VOL. 8, NO. 3, AUGUST 2016

Understanding the potential impacts of climate change on economic outcomes requires knowing how agents might adapt to a changing climate. We exploit large variation in recent temperature and precipitation trends to identify adaptation to climate change in US agriculture, and use this information to generate new estimates of the potential impact of future climate change on agricultural outcomes. Longer run adaptations appear to have mitigated less than half–and more likely none–of the large negative short-run impacts of extreme heat on productivity. Limited recent adaptation implies substantial losses under future climate change in the absence of countervailing investments.

Maybe time to look for High Speed Rail alternatives?

High speed rail (HSR) may not be the best means to moving people quickly from San Francisco to Los Angeles–it looks like a 20th century solution to a 21st century problem. I’ve written written about how electric vehicles will diminish the projected GHG emission reductions, and may be an effective alternative. Now comes a Chinese-designed super bus27chinabus01-master768 that can use the same I-5 lanes simultaneously with cars. (See the video in the link above.) The Dutch have developed a high-speed electric bus that also can use I-5 at little added cost.

And now comes word that the auction of greenhouse gas (GHG) allowances by the State fell well below forecasts. Due to how HSR is funded out of that allowance fund, HSR’s share will fall by 98% to $2.5 million. Given that the state still has not attracted any private investment, which is a necessity to make this go, it may be time to rethink solutions.

Reblog: Leaking Coal to Asia

Maximillian Auffhammer at UC’s Energy Institute @ Haas focuses on the issue of exporting coal from the Port of Oakland, but he turns to the issue I highlighted recently–the path to accomplishing environmental objectives should travel through compensating those who are worse off from such policies.

Differing views of the future? High speed rail vs electric vehicles

As I was driving back from Los Angeles to Davis, I thought about how convenient it would be to turn on an auto pilot that allowed us to lock into the train of cars up Highway 99. The only reason I really had to pay attention was due to the varying speeds of the traffic. But that future may be nearer than we might think. Google’s self-driving car is getting most of the press, but in fact there are many similar technologies already on the road. In fact, there’s been some concern that drivers are already pushing the limits on current controls, but collision avoidance devices may soon be standard equipment.

Which brings us to the question: How will high speed rail fare in a world with driverless electric cars? The high speed rail travel forecast appears to assume a similar mix of gasoline-fueled automobiles; in fact, the word “electric” isn’t even in the report. On the other hand, studies show that EV market share probably needs to reach 45% by 2030 to achieve an 80% reduction in GHG emissions by 2050. And the Air Resources Board is considering regulations to implement “fast refueling / battery exchange” that would make the LA-SF trip even easier in an EV. Given the shorter life of automobiles, we might expect that almost all of the highway trips are with EVs by 2045.

We’re left with the question of what are the true emission reductions from HSR in such a world? Are we building a project that’s truly useful life is less than a decade?
