There's been some talk on a potential feedstock deficit from growing renewable fuels. Here's a story explaining that, and the larger #renewable energy market. https://www.reuters.com/article/us-usa-energy-feedstocks-graphic/u-s-renewable-fuels-market-could-face-feedstock-deficit-idUSKBN2BW0EO #OOTT
Fuels such as biodiesel, renewable diesel and sustainable aviation fuel draw from the same feedstock pool. Goldman Sachs estimates a 13-billion pound feedstock deficit by 2024 bc of renewable diesel capacity. https://graphics.reuters.com/USA-ENERGY/FEEDSTOCKS/yzdvxelkrpx/
Animal fat and grease are used to produce renewable diesel, biodiesel and sustainable aviation fuel. https://graphics.reuters.com/USA-ENERGY/FEEDSTOCKS/qzjvqlrzjpx/index.html
Biomass currently accounts for roughly 5% of U.S. energy use. Meanwhile, renewable energy makes up 9.8% of total energy consumption. That's expected to grow to 12.5% by 2024. https://graphics.reuters.com/USA-ENERGY/FEEDSTOCKS/azgpodooevd/index.html
Renewable diesel and sustainable aviation fuel have both grown in production over the last 5 yrs. There's no official production numbers on either, but here's an analysis of each market, using RIN generation data. https://graphics.reuters.com/USA-ENERGY/FEEDSTOCKS/xklvyraaepg/
