This dissertation employ applied microeconomics techniques with a specific emphasis on behavioral dynamics within the realms of energy and environmental economics. In Chapter one, we investigates the impact of outdoor temperature on productivity in the service sector, using data from the India Human Development Survey. Our findings suggest a precisely estimated zero effect on interview duration, ruling out significant productivity impacts. In Chapter two, we employs a conditional demand analysis on a Canadian electricity consumer data set, highlighting the effectiveness of local heat pumps and thermostat setbacks for electricity savings. Results also reveal trends favoring newer homes in electricity consumption decline. In Chapter three, I study the causal relationship of spatial peer effects from Canada's largest home energy efficiency retrofit program on energy consumption. My results show that close neighbors to energy efficiency retrofitted homes experience a significant reduction in monthly natural gas and electricity consumption. Moreover, visible retrofits, such as windows and doors, significantly impact peer energy savings compared to less visible retrofits.
