STAVANGER, Norway (Reuters) -- Tesla chief Elon Musk said on Monday the world must continue to extract oil and gas in order to sustain civilization, while also developing sustainable sources of energy. “Realistically I think we need to use oil and gas in the short term, because otherwise civilization will crumble,” Musk told reporters on the sidelines of the conference. 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,” he said. “That will take some decades to complete.”
He said offshore wind power generation in the North Sea, combined with stationary battery packs, could become a key source of energy. “It could provide a strong, sustainable energy source in winter,” he said.
