Clean, affordable and secure energy should be available to all people, and the costs of energy should be borne equitably. Stanford researchers study sustainable energy growth in developing countries, and how expanded production of biofuels, especially ethanol, is affecting economic development, food security, commodity markets and farmer incomes in all countries. Other research areas include strategy and performance of state-owned oil companies in oil-exporting countries, and resolving conflicts over major infrastructure, such as liquefied natural gas facilities and oil pipelines.
