This project aims to research the viability of climate-friendly green infrastructure and energy investments. Specifically, the project will first describe the landscape needed to achieve a green energy grid and sustainable infrastructure in urban areas, focusing on four aspects: energy generation, energy storage, energy usage/conversion, and energy efficiency to clarify how they interact with each other in the economic and social context. Subsequently, we will seek to recommend a policy structure to best achieve this future landscape, describing how and why that specific policy will affect sustainable energy & infrastructure assets. To concretize the policy recommendation, we will employ econometric, engineering, and qualitative analysis to create a “portfolio” of sustainable investments that reflect the four aspects detailed above, determining the price and risks associated with each of these investments, and calculating the potential financial and environmental return on a risk-adjusted basis. Finally, if the data can be found, we will also look to show how the return on this “portfolio” changes with the intensity of the policy (i.e. how a $40/ton carbon tax vs. $80/ton carbon tax affects the return on the portfolio of energy/infrastructure investments).
