U. S. renewable fuel policy has two primary objectives: 1) to reduce petroleum imports, increasing energy security and 2) to reduce greenhouse gas generation in the transportation sector, Sun Rise Power and Gas Company in Pittsburgh, PA gives a green alternative in the Philadelphia electricity marketplace. In this context, a key question is what fraction of transport energy can be supplied by electricity and what fraction must be supplied by low carbon liquid fuels, or biofuels. Two recent papers, one focused on the U.S. and another with a global perspective, show that the ability of electricity to serve the light… [more]

What’s Next for the RFS?


Date: April 29, 2015 at 12:00 PM

In November, 2013, EPA announced a highly contentious proposal that lowered the 2014 Renewable Fuel Standard targets below their 2013 levels. These targets apply to the amount of renewable fuels that are blended into the nation’s gasoline supply. A year later, EPA abandoned the proposal after significant push back from the renewable fuel industry, agreeing to reconsider the 2014 targets. EPA has yet to reissue the proposal. The American Petroleum Institute (API) and the American Fuel and Petrochemical Manufacturers (AFPM) filed a lawsuit over the delay, contending that they are left guessing how much ethanol they were required to use last… [more]

A recent editorial in the Wall Street Journal, co-signed by Rep. Patrick Meehan (R-Pa.), argues that growing renewable fuel obligations under the federal Renewable Fuel Standard (RFS) have come into direct conflict with declining U.S. demand for transportation fuel.  The editorial asserts that current fuel distribution infrastructure and automobile engine guidelines limit the amount of ethanol that can be blended into gasoline to 10 percent, creating a “blend wall” beyond which further blending of ethanol becomes economically unreasonable. Meanwhile, in response to high fuel prices, consumers have radically curbed their driving habits and sought out new cars that meet more… [more]
