"We are going to run out" (of gas)

On Wednesday 7 Sept at 0710 hrs on the Radio 4 'Today' programme, I heard Paul Johnson, Director of the Institute for Fiscal Studies, say:

"The reason gas prices are so high is because there is less gas around.  If the world doesn't use less gas over the next year, we are going to run out."

The other sensible person who speaks truth to power is the consumer champion, Martin Lewis.  They need to be joint/co Prime Ministers, in my opinion.
