Energy Systems

Energy sectors account for roughly two thirds (~64%) of total greenhouse gas emissions contributing to global warming. This includes everything from the fuels that powers our vehicles and heat our homes to commercial and industrial consumption of electricity and fossil fuels. Our researchers model various energy-production scenarios that would allow countries to decrease their carbon footprint while meeting goals for more sustainable growth and development. They also study the policies and incentives that govern decision-making around energy sectors, including the role of foreign investment in emerging markets.
