2015 was a banner year for Renewables. The EPA finally finalized RFS volumes for 2014-2016 in November. In December, Congress passed the tax extenders package which included both the $1 per gallon biodiesel blender credit and cellulosic blending credit of $1.01 per gallon, retroactively.
We also saw the Paris Climate Change Summit in November (Here's a quick recap of where we were then in terms of Climate Change regulations). The Summit saw 190 countries agree to Climate Change resolutions and almost univerally agreeing that each country would lower its carbon emissions.
2015 saw increases in renewable fuels use essentially across the board, and 2016 projections are optimistic on growth. I wrote an article for Oil & Energy's March issue that goes into depth on current levels, projections, and how the renewables mix looks like it will shake out through 2016.
