Indian biodiesel buses switch back to fossil as prices get too high

In India, Karnataka has stopped blending pongamia oil with diesel to run its public transport buses because the oil company boosted the price of bulk diesel. Since Karnataka State Road Transport Corporation does not have its own blending facility it relies on public pumps. Until the price of bulk diesel comes back down, the nearly 1,000 buses that were running on biofuel blends will run on straight fossil diesel.
