The Ethanol Link between Food and Energy Prices in Pictures
US government promotion of the ethanol industry is an important element in the recent spikes in corn (and other food) prices, but rising oil and gasoline prices are also key contributors. This is the punch line of a recent presentation I gave on US biofuel policy, and a point that can be clearly illustrated in just two charts: the first chart provides a crude summary of key elements of US biofuels policy; the second chart shows trends in ethanol production, corn prices, and crude oil prices all starting to move together in the mid-2000s.
