Environmental footprints

After Obama was elected, businesses thought that environmental regulations were coming. Pepsi/ Tropicana researched the carbon footprint of orange juice, finding that fertilizers were the biggest part of the impact. Now, eight years later, I see the second footprint analysis, finding again that for a food product (in this case bread) the impact of fertilizer comprises 40% of the impact. That far outweighs transportation, packaging, and all other individual part of the story.

A few questions: first, why are these analyses still so rare? The more recent one was done by academic researchers, highlighting the answer to my question: government doesn't require them. I guess it's like the gun lobby banning research on guns- if you don't hear about it, it must not be a real issue. Second, how about that fertilizer? That's really a problem: it's come up big in two studies. I wonder what % of food's carbon footprint is attributable to fertilizer? As Lamar Odom used to say, "Not small!"

Heartland vs. Trump

One way Mexico may try to indicate their displeasure with our current administration is to buy fewer products from the US. One large US export, corn, goes predominantly to that country, and though it's not as easy as they would like to find another supplier that can produce as much as we can here in the US, a significant cut in their imports could adversely affect the price of US corn, and hurt farmers' pocketbooks. Since these farmers are living on a fairly thin margin, with costs up and revenue down over the past few years, a drop in prices could really hit agriculture where it hurts. Otherwise, the prognosis is for corn prices to stay about the same in the short run, at least.

Update on offshore wind

For years I've been telling my Resource Econ class that offshore wind just isn't economic. I hadn't been able to find any cost estimates since the EIA posted these in 2011:

With Offshore looking like it costs three times the price of onshore wind, it didn't seem to make much sense. However, the tech seems to have improved over the past five years. (Go engineers!) This NYT article says that costs on one project were as low as 78 Euros/MWh or about $83. Wow! That's quite an improvement. If those costs are sustainable, i.e. not just building costs but maintenance costs and all, that could be huge. Some good news in bleak times for clean energy....
