Headline: energy needs to grow

Recently I was thrown by a headline used on a BBC News Science/Nature story:

Energy needs 'to grow inexorably'

Missing the single quote marks, I took this to mean 'energy has to grow inexorably', leaving me wondering how energy can grow. What the headline actually meant was 'energy needs are set to grow inexorably'.

For once, this bit of verb/noun confusion wasn't even caused by a lack of headline space...
