Elon Musk says the world still needs oil and gas

The world must continue to extract oil and gas in order to sustain civilisation, while continuing to also develop sustainable sources of energy, Tesla founder Elon Musk told reporters at a conference in Norway on Monday.

"Realistically I think we need to use oil and gas in the short-term, because otherwise civilisation will crumble," Musk said. Asked if Norway should continue to drill for oil and gas, Musk said: "I think some additional exploration is warranted at this time.

"One of the biggest challenges the world has ever faced is the transition to sustainable energy and to a sustainable economy ... that will take some decades to complete."
