The document summarizes key findings from an Accenture analysis of how demand for different energy sources may change between now and 2035. It identifies five portfolio plays that could help oil and gas companies succeed in the changing energy landscape: 1) Growing natural gas demand, especially in Asia. 2) Producing oil at the lowest possible cost. 3) Developing carbon capture and industrial efficiency technologies. 4) Producing "blue" hydrogen from natural gas with carbon capture. 5) Winning in biofuels and low-carbon products like bio-lubricants. The analysis projects continued overall energy demand growth but significant changes in the fuel mix across regions and sectors.
