Kirsty Johnston digs into the detail of the Government's repeal of the oil and gas exploration ban and asks a pertinent question: what if it doesn't work? "Forecasts say there is barely enough gas left in our existing oil and gas fields to last the decade, and even that is an optimistic guess. Demand now outstrips supply, forcing some businesses to struggle for gas, others onto 'demand management' plans requiring production shutdowns to support the electricity grid, and some to close operations entirely."
