Mark Jacobson is a leading expert in wind energy and the atmosphere. He hears some of the claims being made on behalf of E85 — that it’s supposed to be cleaner, that it will reduce ozone-forming pollution and the release of harmful compounds like benzene, toluene and xylene. Mark’s research shows that these statements are misleading, and he strongly disagrees: Burning E85 will not lead to reductions in harmful emissions, he says.
