4:19 PM | Could sugar dumping push ethanol production up?
Pulling out an interesting little option from the 2008 Farm bill, the USDA is considering re-directing US produced sugar to ethanol production to drive up sugar prices.  From what I understand, the US sugar industry is completely supported by farm … Continue reading →

2:52 PM | The “future” of clean coal – is not in our future
A new report from the CRS reveals the sad state of what many believe is an impossible venture – “clean coal” that involves capturing the CO2 released as the coal is burned: http://thehill.com/blogs/e2-wire/e2-wire/293655-report-federal-clean-coal-power-project-faces-uncertain-future

3:20 PM | IMF report on energy subsidies, implications for a carbon tax & energy security
IMF presents some new analysis of energy subsidies which I have previously wondered about.  It is worth looking over: http://www.washingtonpost.com/blogs/wonkblog/wp/2013/03/27/imf-want-to-fight-climate-change-get-rid-of-1-9-trillion-in-energy-subsidies/ $25/ton as the cost of carbon seems low to me.  $502 billion in US energy subsidies including this carbon tax.. I don’t … Continue reading →

3:05 PM | post about RINs, ethanol, etc
As we’ve hinted at before, some interesting things are starting to happen with high corn prices, high RIN prices, the blend wall and ever compounding RFS requirements! We all know that corn prices have been high – so high in … Continue reading →

4:03 PM | the rebound effect and how energy efficiency may not be the “low hanging fruit”
An interesting paradox: as we conserve more energy, we use more. We pointed out some research in the past on this effect, and some debate about the potential impact of this effect has surfaced in a couple places.  First, there … Continue reading →

8:45 PM | Has biofuels led to major land use changes in the US?
And is the land that is being converted from grassland to corn and soy the “marginal land” that people take about growing dedicated bioenergy crops?  A new article in PNAS this week seems to answer “yes” to both these questions. … Continue reading →

7:41 PM | updates on the court challenge to the RFS: minimal long-term impact
