Energy is only one issue. There is also that plastic is a petroleum product. Also even if "managed" well ultimately ends up in the landfills, and its resources don't get recycled by the environment for thousands of years. It also wreaks havoc on the environment if it ends up in the wrong place; paper largely doesn't.
